Introduction

S.A.E. STANDARDS ROLL-OVER PROTECTION STRUCTURES (ROPS) FALLING OBJECTS PROTECTION STRUCTURES (FOPS) OPERATOR PROTECTION STRUCTURES (OPS) * MODIFICATIONS AND REPAIRS: The integrity of the ROPS, FOPS, OPS structure and its continued ability to provide the level of protection it was designed for could be seriously affected by any modifications to the structure, its mounting or to the chassis to which it is attached.

Tigercat emphasizes that the certification of approval of the ROPS, FOPS, OPS structure will become void if any such modification(s) take place.

Tigercat may officially grant approval for modifications only by: i. Written approval of repairs or modifications signed by the Tigercat Engineering Manager; or ii. Approved modifications officially released by Tigercat.

Both of the above are provided that the work is carried out in the factory approved manner.

Unauthorized modifications and/or repairs made or contributed to by a customer or a Tigercat distributor may result in creating a dangerous situation and therefore the customer or Tigercat distributor will be considered to have assumed the risk involved or be negligent in creating this situation.

Tigercat will not be held responsible for situations arising from having created unauthorized modifications/changes to the structure.

Operator's cabs are designed to ROPS, FOPS, OPS standards so that they will withstand force and absorb energy during a roll-over (ROPS), when resisting the impact of a falling object (FOPS) and minimize the posibility of operator injury from penetrating objects (OPS). When a permanent deflection of the structure occurs, the structure can no longer provide the original designed level of protection and should be replaced. Attempts to straighten the structure, particularly by the application of heat, can reduce still further the structures remaining capability to protect.

The mounting and the frame or chassis to which the cab is attached is considered an integral part of the ROPS, FOPS, OPS and is included in the design, test and certification of the product.

Contact the Tigercat Service department before attempting any modifications or repair to roll-over protective structures.

Safety

Safety Hazards - Viton Seals O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (Hydrofluoric) when subjected to temperatures above 315°C (600°F).

Maintain a distance of 3 m (10 ft) between the machine or boom and any power line carrying up to 50,000 volts or less plus 10 mm (½ in.) for each additional 1,000 volts above the 50,000 volt level.

If State/Provincial, local or job site regulations require even greater safety distances than stated above, adhere strictly to these regulations for your own protection.

This contamination can have extreme consequences on human tissue since it is almost impossible to remove after contact.

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to VEHICLE MOVING INSTRUCTIONS in SECTION 2 of the OPERATOR'S MANUAL.

The following procedures are recommended when inspecting equipment that has been subjected to high temperatures such as fire: •

Visually inspect any seals or gaskets which have suffered from heat; they will appear black and sticky.

•

If these are found, Do Not Touch!!!

•

Determine the material composition of any seals or gaskets. If fluoro-elastomer seals (Viton, fluorel, or tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.

•

Disposable heavy duty gloves (neoprene) must be worn and the affected area decontaminated by washing thoroughly with limewater (Calcium Hydroxide solution).

•

Any cloths, residue and gloves must be safely discarded after use.

Even though the brakes are fully engaged, block the wheels to prevent movement during transport.

Install the articulation lock bar when ever the machine is to be transported.

Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.

Reduce engine speed to LOW IDLE and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

NOTE: Burning discarded items is not recommended except in an approved incineration process where the dangerous products are treated by alkaline scrubbing.

Safety Hazards - Operating Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT.

Be aware when performing service and maintenance tasks that surfaces and grab handles in and around the engine and cooling system may become very hot when the engine has been running. Contact with hot surfaces may cause injury.

Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided and approved with seating for the operator only.

Comply with instructions in this manual and also your company’s regulations for the operation of this machine.

Do not allow anyone to operate the machine who may not be physically fit or who may be under the influence of alcohol or drugs.

Read, understand and follow all general safety precautions specified by attachment manufacturer.

When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.

WARNING Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Approach with extreme caution any area where overhanging electrical power lines are present.

Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines.

MULCHING OPERATION SAFETY

DANGER ZONES

Land clearing operations generally involve other machinery and people on the site. Operators must maintain an awareness of all working traffic within 500 feet of the mulching operation.

Danger exists most prominently to the rear and front of the mulching head.

Operate so that the main discharge areas of the mulching head are not directed at people, livestock, buildings or other machines.

Pieces of wood, debris from the ground and even cutting tools separating from the rotor become potentially dangerous projectiles when thrown from these machines.

Throw distance for metal pieces and stones can be many times the distance for wood chips.

Danger is greater if the site contains stones or abandoned metal.

Inspect cutter tools, cutter tool fasteners, rotor and mulching head assembly.

Poor maintenance increases the danger.

Thorough timely inspection and replacement of worn cutter tools, fasteners and wear plates.

Always heed warning signs of missing cutter tool parts or sounds of striking rocks and adjust operation to suit the site.

Ensure that all cutter tool retaining bolts are at correct torque value.

Replace all worn cutter tools.

Always replace the fastener whenever replacing a cutter tool.

Do not operate in a way that throws chips in a direct line at the machine cab.

Inspect the rotor for weld cracks and other damage.

REAR DANGER ZONE

Check that the rotor does not wobble due to worn shaft bearings.

Chunks of wood and rock can be thrown from the rear of the mulching head. This occurs when the mulching head is raised high enough to allow debris to escape the guard chains. No one should be allowed within the HAZARD ZONE. This condition is dangerous, refer to HAZARD ZONE in THIS SECTION. The following precautions should be followed:

Never start or use a machine if the rotor has missing cutting tools, missing cutting tool fasteners or a bent rotor.

Shut down the machine immediately if you feel excessive vibration when the rotating cutter is running.

Check that the cutter housing is clear and undamaged.

• •

DANGER

•

ROTATING CUTTER

The safety of persons outside the cab is the responsibility of the machine operator.

Danger caused by flying debris. Improper operation of the attachment and failure to follow safety precautions can result in personal injury.

FRONT DANGER ZONE

FRONT DANGER ZONE To the front a lower volume of projectiles may be experienced. However, no one should be allowed within the HAZARD ZONE. Refer to HAZARD ZONE in THIS SECTION. The following precautions should be followed:

REAR DANGER ZONE

• •

URBAN PRECAUTIONS

ANIMAL REMAINS

Increased safety precautions are required when working:

Animal remains such as calf and deer carcasses will plug the machine due to their leathery skin.

Avoid the unpleasant task of removing the remains from the rotor.

• • • •

Near streets Near highways In parks, on golf courses or other inhabited areas.

Near buildings

AVOID FENCES Do not drive the mulcher into fences, especially chain link fences. Chain link fencing can damage the rotor. Refer to AVOID METAL AND WIRE above.

Establish Safety parameters that fit the site: • • •

String coloured warning tape to cordon off the area.

Use a traffic director when the hazard zone impinges on pedestrian or vehicular traffic.

Erect barriers.

When operating mulching head properly position head for push working and pull working for safety and improved operation.

When tree toppling always know and control the direction a tree will fall to prevent injury to coworkers or damage other vehicles.

ASSESSING THE POTENTIAL DANGERS OF THE JOB SITE

IMPORTANT! To prevent component damage, always have deflector door open when preparing to fell standing trees

Before working in a new area a visual survey of the area to be worked is helpful in identifying undesirable materials which may be present.

Remove as much of the undesirable materials as is practical before proceeding.

Work within your operating skills, do not attempt to cut down a tree that is too large to handle.

AVOID METAL AND WIRE.

When pull working (moving in reverse), watch for obstacles in your path.

Metal can break cutter tools and create a projectile hazard.

Always travel with mulching head as close to the ground as possible, never elevate the mulching head unless necessary.

Wire wraps itself around the rotor shaft especially near the bearings. Near bearings this can cause wire to enter past the grease seals and cause damage to bearings if it is not removed promptly.

Never use this machine to clear an area when other equipment and operator's are also moving in. Pre-plan to work the area in advance before other equipment arrives.

USE CAUTION WITH STRINGY VEGETATION Shredding materials like Palmetto, Bird of Paradise, and yard waste tied with plastic should be approached with caution. Stringy vegetation and plastic ties gravitate toward the bearings.

The operator should exercise caution while working with this type of material.

Never work alone. Regularly inform other crew members of your intentions, location and length of time to perform duties.

Stop the rotating cutter before leaving the mulching area. NOTE: The cutter will continue to free wheel for several minutes after the cutter switch has been turned OFF.

AVOID PLASTICS Hoses, bags, tarps and ropes must be removed as soon as they are seen.

To stop cutter from rotating, CAREFULLY lower the rotor onto a stump. This should be done gently to prevent unnecessary loading of the rotor, housing and bearings.

Mattresses, rugs, clothes and cloth will plug the machine immediately.

Inspect the rotor for clinging strands often.

Safety GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 - 400 Bar (246 - 5801 psi).

It takes less than 7 Bar (100 psi) to inject a substance through human skin.

ALWAYS get professional medical treatment immediately after any type of injection injury.

Provide the physician with information on the type of grease, the pressure setting of the gun, and similar details.

If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a buildup of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.

The amount of fluid injected, type of fluid (or material), pressure at which it was injected, and the elapsed time between injection and surgery all influence the chances of successful treatment for this type of serious injury.

Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.

Prior to using a high pressure pneumatic grease gun perform the following:

If you don't have an exhaust pipe extension, either work outside, or open the shop doors.

Dispose of fluids properly.

Do not pour fluids into the ground, stream, pond or lake.

Before draining any fluids, know the proper way to dispose of them.

1.16

•

All operators of high pressure pneumatic grease guns MUST be trained in the hazards of its operations and the treatment for such injuries.

•

DO NOT OPERATE a high pressure pneumatic grease gun unless you have been trained in the proper operation and are aware of all safety precautions of such a tool.

•

Wear protective clothing such as gloves, safety hat and safety glasses.

•

Inspect all parts of the grease gun for wear and tear and replace all worn or damaged parts.

•

Ensure that protective shrouds are installed on all grease gun nozzles as safety devices.

•

Remove dirt and grease from grease fittings prior to greasing.

•

Replace any defective grease fittings on equipment with new fittings immediately.

•

When badly positioned fittings are identified, replace them with angled or swivel fittings for easier access.

Safety

FLUID INJECTION INJURY

WARNING

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose should occur, a fine, high velocity stream of fluid will result. Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.

Diesel fuel or hydraulic fluid under pressure can penetrate the skin and could result in death or serious injury. If any fluid is injected under the skin, a medical doctor familiar with the treatment of this type of injury must surgically remove it within a few hours.

In the event of any suspected fluid injection injury • Report the injury to your supervisor immediately.

• Seek professional medical attention immediately.

As always the best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

When searching for possible fluid leaks • Never search for leaks with your bare hands.

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

• Keep all body parts well away from the area being investigated for leaks.

• Use the end of a long piece of wood to move hoses or other obstacles.

Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation.

There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun.

Similarly fluid injected directly into a blood vessel can spread rapidly through your circulatory system. The human body has little ability to purge injected fluid.

Diesel fuel or hydraulic fluid under pressure can penetrate the skin and could result in death or serious injury. If any fluid is injected under the skin, a medical doctor familiar with the treatment of this type of injury must surgically remove it within a few hours.

•

Place the end of a long piece of wood in the suspected path of any fluid stream. Never use any part of your body.

• Recognize that the source of the leak and the fluid streaming from it may be very small and not easily visible. You may only be able to see the fluid that accumulates as a result of the fluid stream.

When performing any service work • Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

• Never grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

• Always ensure that hoses are rated for the pressures to which they will be subjected.

• Never use any hoses that you suspect could be defective.

Time becomes critical as tissue damage progresses rapidly. The longer you delay getting professional medical attention, the more damage can occur.

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

Safety LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

In spite of the popular myth that being struck by lightning is an unlikely event, the facts show that lightning strikes occur frequently. As a result loggers are at high risk because their work is outdoors and close to known strike points such as tall trees and heavy equipment.

Loggers can increase their chances of avoiding a lightning strike by following a few simple safety practices.

1. Designate a member of your crew to

WHAT IS A LIGHTNING STRIKE? Lightning is a discharge of the electricity produced by a thunderstorm. As the thunderstorm develops, many small particles of ice within the storm clouds bump together. These collisions create a positive charge at the top of a cloud and a negative charge at the bottom. As this continues a second positive charge builds up on the ground beneath the cloud, concentrated around high objects such as hills, trees, buildings, equipment and even people.

•

Monitor daily weather forecasts

•

Observe local weather conditions

•

Alert all other members of the crew when a possible lightning threat develops.

2. Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

3. Anticipate a high-risk situation and take action early by moving to a low-risk location. Do not hesitate. If there is lightning, you are in danger.

When the difference between the electrical charge in the cloud and on the ground becomes great enough to overcome the resistance of the insulating air between them, an electrical current flows instantly. This is a lightning strike.

4. Obey the rule - If you see lightning, Flee. If you hear thunder, Clear.

5. Do not follow the now obsolete guideline to take shelter when the time between seeing lightning and hearing thunder is 30 seconds or less. This does not provide sufficient time to ensure safety. Always follow step 4.

The electrical potential in a lightning strike can be as much as 100 million volts. Lightning strikes can occur over very large distances, even as much as 60 km (37 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped.

Lightning can hit in the same place, many times and often spreads out over 18 m (60 feet) within the soil around the strike point.

6. Remain in your safe location for 30 minutes after the last sight of lightning or the last sound of thunder.

The safest location during lightning activity is inside a fully enclosed, substantially constructed building, a house, office, school, shopping area, etc. These are the safest because of the electrical wiring and plumbing that they contain. Should lightning strike, the electrical current will travel through the wiring or plumbing into the ground.

When such a building is nearby, always seek shelter there first.

Thunder always accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F). The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

In many areas of the world, lightning strikes are second only to flooding as the greatest cause of storm related deaths and injuries. Although only 10% of lightning strike victims are killed, virtually all from cardiac or respiratory arrest, over 70% of those that survive suffer severe, life-long injury and disability. The symptoms of a lightning strike include memory loss, fatigue, chronic pain, dizziness, sleeping difficulty and the inability to complete several tasks at one time.

1.18

Tigercat M726E Mulcher

Safety WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER.

Unfortunately loggers do not often work close to buildings and therefore other alternatives need to be considered.

If you can, get inside.

Sheds, weather shelters, hunting blinds, tents and other partially open or small structures are not safe against lightning strikes as they lack the electrically grounded components of larger buildings. They are intended for sun or rain protection only. Do not seek shelter from lightning strikes inside these structures.

1. Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately. Being anywhere outside is not safe.

2. If inside a building:

The second safest location during lightning activity is inside a fully enclosed car, van, truck or bus with a metal roof and metal sides. The electrical energy of a lightning strike to these vehicles is carried to ground by the conducting outer metal surfaces. This is called the skin effect.

Do not seek safety from lightning strikes in vehicles with fiberglass or plastic body shells or in convertible top vehicles. None of these are safe, as they do not offer skin effect lightning protection.

•

Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

•

Stay well away from corded telephones, electrical appliances, lighting fixtures, radio microphones, electrical sockets and plumbing pipes and fixtures.

3. If inside a motor vehicle or fully enclosed ROPS equipment cab:

Heavy forestry equipment such as a skidder, loader, feller buncher, forwarder, etc. with a fully enclosed rollover protective structure (ROPS) cab take advantage of the skin effect and are therefore safe in electrical storms.

However machines with a rollover canopy only are not safe against lightning strikes as they are open to electrically conductive rainwater and do not benefit from the skin effect. Operators of this equipment must abandon their machines and get to a safer location before lightning strikes.

Note that the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes. Lightning has already travelled a great distance through the air to strike the vehicle.

In comparison a few inches of rubber in a tire offers absolutely no additional insulation.

1.19

•

Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

•

Shut down all operation, turn off the engine, close all doors and raise all windows.

•

Sit squarely in the seat with your hands in your lap and your feet flat on the floor mat.

•

Do not touch any metallic objects referenced to the outside of the vehicle.

Do not touch any door and window handles, control levers, foot pedals, steering wheels, cab interior walls and any other inside to outside metal objects.

•

Do not touch any radio or telephone connected to an outside antenna.

Tigercat M726E Mulcher

Safety

If you are caught outside and have no where else to go.

What to do if you feel your skin tingling, your hair stands on end, light metal objects vibrate or you hear a crackling sound.

1. Avoid wide-open areas where you project above the surrounding landscape.

1. Lightning is probably about to strike. You only have a few seconds to act.

2. Seek shelter in a low place, such as a ditch, ravine, valley, canyon or cave.

2. Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down. Cover your ears to protect them against the noise of the thunder.

3. Get away from open water such as ponds or streams.

4. Do not take shelter under any isolated tall trees or small groups of trees.

3. Do not lie flat on the ground. By touching as little of the ground as possible, the lightning may not move across the ground to you.

5. Seek shelter amongst the dense, thick growth of the shortest trees.

What to do if a co-worker has been struck by lightning.

6. Avoid entering any small enclosures or shelters.

1. The victim does not carry any electrical charge. There is no danger to anyone helping this person. You can touch him or her immediately.

7. Do not seek shelter under any motor vehicle or heavy equipment.

8. Keep clear of any materials that can conduct electricity such as wire fences and gates, metal pipes, poles, rails and tools.

2. Call your local emergency response telephone number immediately.

9. Stay at least 15m (50 feet) away from metal objects such as a fuel tank, a vehicle or machinery without a cab, motorcycle, ATV, etc.

10. Stay at least 5m (16 feet) apart from any other members of a group so that lightning won’t travel between you.

11. Do not use the telephone except for emergencies.

3. If the victim has no pulse, their heart has stopped or they have stopped breathing, start cardiopulmonary resuscitation (CPR) or mouth –to-mouth resuscitation immediately. Use a portable defibrillator if one is available.

4. Be careful about staying in the storm to take care of the victim. You can get hit by lightning too. If you can, move the victim to a building as soon as possible.

Safety 4. Clean out all accumulated forest debris (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials from inside the machine belly pans or lower machine structures as well as from areas in proximity to the engine, fuel and hydraulic oil systems no less frequently than at the completion of each work shift.

FIRE PREVENTION

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris, in itself, may cause a fire; however, when mixed with fuel, oil or grease in a hot or confined place, the danger of fire is greatly increased.

The following fire prevention guidelines should be used to supplement the operator’s fire prevention efforts. In no case should the guidelines be used, or assumed, as replacements for diligent operator efforts at preventing fires.

The following guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum.

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 2. Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 3. Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smolder. If dislodged this smoldering debris can fall into other areas of the machine and thereby spread a fire.

5. Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage.

Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

6. Clean up any grease, diesel fuel, hydraulic and lubricating oil accumulation and spillage immediately.

7. Steam clean the engine, transmission, brake, fuel and hydraulic tank compartments of all equipment at least once a month or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

8. Use only nonflammable solutions for cleaning the machine and components.

9. Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler. Also check for missing or damaged bolts or clamps.

Should any exhaust leaks or defective parts be found, repairs must be made immediately.

Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

10. During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

11. Park the machine at least 50 feet away from other equipment at the end of each shift.

12. Never leave the machine parked with boom, arch or blade suspended off the ground. Should their supporting hydraulic hoses burn through during a fire, pressurized hydraulic oil may be injected into the fire and the boom, arch or blade will fall rapidly to the ground.

1.21

Tigercat M726E Mulcher 13. Turn the battery disconnect switch to OFF at shut down to de-energize all electrical circuits.

14. Remain with the machine for at least 45 minutes at the end of operations while the machine cools.

Safety 17. AFTER transporting (trucking) a machine from one job site to the next, open all doors and access panels and blow off any debris that may have repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

18. Before starting repair work, such as welding, the surrounding area should be cleaned and a fire extinguisher should be close by.

19. Store rags and other combustible materials in a safe, fireproof location.

20. Do not use the machine on top of or to push piles of burning timber. A machine fire will most probably result.

EQUIPMENT FIRES ADVERSELY EFFECT YOUR ABILITY TO LOG, MAY INCREASE YOUR INSURANCE PREMIUMS DRAMATICALLY OR PREVENT YOU FROM OBTAINING INSURANCE COVERAGE AT ALL. WHAT TO DO TO PREPARE FOR A MACHINE FIRE

15. Remove all keys, lock equipment and fuel cap at the end of operations to reduce the risk of vandalism.

•

Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and always well maintained.

•

Ensure that any hand held fire extinguishers are charged and in working order. Fire extinguishers require routine care. Follow the manufacturer’s instructions for inspection and maintenance shown on the label of the fire extinguisher and in the extinguisher manufacturer's manual.

•

Ensure that any pressurized water systems on the machine (if applicable) are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3 of the OPERATOR’S MANUAL.

•

Ensure that you have the proper fire extinguishers on site. Most fires involving mobile forestry equipment will be Class A or B. Dry chemical extinguishers should be rated ABC and pressurized water extinguishers should be rated A. Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics, Class B fires occur with flammable liquids such as diesel fuel, oil and grease and Class C fires apply to energized electrical equipment.

16. Be cautious when smoking. An open flame, a lighted cigarette, etc., should not be permitted around any vehicle, especially during fuelling operations or when the fuel system is open to the atmosphere or when servicing batteries.

1.24

Tigercat M726E Mulcher DRY CHEMICAL CLEANUP PROCEDURES Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability. These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

Safety 3. In areas exposed to heat during the fire, the dry chemical powder will melt forming a coating that cakes or crusts on all surfaces.

To break down the caked dry chemical, spray or wash these areas with a 50/50 mixture of hot water and isopropyl alcohol. Allow this mixture to stand in place for several minutes.

The caked dry chemical when exposed to moisture is also mildly acidic. Therefore when the break down procedure has been completed, follow this immediately with the neutralizing procedure as described in step 2.

The following are recommendations for the cleanup and neutralizing of areas exposed to dry chemical powder.

Workers performing this work should wear protective clothing, safety goggles and a fine particle dust mask to minimize their personal exposure to the dry chemical powder.

Ensure that all electrical systems have been completely de-energized prior to any cleanup.

1. In areas of the machine that remained cool and dry during the fire, the dry chemical will stay in powder form.

Be certain to clean these areas immediately to prevent any settled residual powder from coming into contact with moisture whether through direct contact or humidity in the air.

Remove the powder residue by blowing off with air, sweeping, dusting or vacuuming using a HEPA filter capable of trapping the small dry chemical particles. Then wipe all surfaces with a damp cloth.

2. In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic. Note that all surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of 3 parts hot water to 1 part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution.

Rinse thoroughly with water. Blow-dry to remove all residual water.

Cleaning of electrical contacts should be done using an electrical contact cleaner that has no flash or fire point and is non-corrosive and non-conductive such as CRC Contact Cleaner 2000.

Several types of heads involved Tigercat wheel type feller-bunchers and crawler feller-bunchers can be supplied with several optional makes and models of high speed disc saw tree felling heads. Because each has certain advantages and disadvantages they are chosen where they best do specific types of work.

Stored energy The saw blade stores energy from the hydraulic motor during the times between tree cuts so that it can supply up to 1000 hp during a 1 sec tree cut. However this rotational energy, if misapplied can result in wood materials or other objects being thrown strongly enough to cause damage and to hurt people.

Be aware of the hazards It is important that users of machines with disc saw felling heads are aware of certain safety precautions that need to be taken. In this section some previously unknown, unexpected safety hazards are illustrated and explained . These should be studied before use of the machinery and then reviewed again after use has begun.

Safe practices It is understood and expected that logging organizations and operators will develop and practice additional rules that suit (for example) particular conditions of terrain, trees, soil and job requirements. The information given here is intended to assist towards a quicker understanding of how and why things can happen when a high speed disc saw is in use; and hence to assist in development of safe operating practices.

It should not be assumed that all possible dangers have been discovered and described here.

Other instructions It is also understood and expected that all instructions contained in service and operator's manuals for use and maintenance of Tigercat disc saw heads and other disc saw heads installed on Tigercat machines will be followed.

THE DANGERS

There are at least these means by which a rotating disc saw can cause harm by throwing: • The normal throwing of chips from the cut.

• Soil particles are thrown from the ground.

• Loose chunks of wood encountered or produced are tossed by the exposed blade.

• Sticks and debris falling onto the blade or sliding across the blade are struck by the teeth and thrown.

• Metal pieces from the blade or from objects encountered are thrown.

• Wood pieces enter the saw housing and are expelled by the blade.

• In very peculiar cases the saw can throw long lengths of wood as spears.

TYPE OF HOUSING MAKES A DIFFERENCE Since the configuration of the saw housing can affect the safety of its use we need to identify some particular types of housing shapes and guarding being used.

Figure 3 shows a typical commonly used saw housing plan where there is a continuous skirt around the saw except at a mouth opening where the trees are cut and taken. The skirt extends below the saw enough to intercept tangential throw. There are snouts on both sides of the mouth so that if pushed against the side of a felled tree or log the saw teeth will not contact the wood.

THROW ANGLE

IF A SAW HEAD IS PUSHED AGAINST THE SIDE OF A FELLED TREE, SNOUTS PREVENT SAW TEETH FROM CONTACTING WOOD.

FIGURE 3: TYPICAL COMMONLY USED SAW HOUSING, CONTINUOUS SKIRT WITH OPENING WHERE TREES ARE CUT. SNOUTS ON BOTH SIDES OF THE MOUTH.

4

Using high speed disc saws safely

Tigercat

Figure 4 shows another commonly used plan. It has no blade guarding snouts so that the saw blade teeth do protrude ahead of the housing. This may be preferred over figures 3 and 5 for dexterity in tree getting.

THROW ANGLE

IF A SAW HEAD WITHOUT SNOUTS IS PUSHED AGAINST THE SIDE OF A FELLED TREE, SAW TEETH WILL CONTACT WOOD.

FIGURE 4: ANOTHER COMMONLY USED HOUSING PLAN WITH NO SNOUTS, BLADE TEETH PROTRUDE AHEAD OF THE HOUSING.

In figure 5 there is a much longer snout on the ingoing side of the mouth, i.e., where the teeth of the rotating blade are entering the housing. The broad side of a log, if nudged, will not contact the saw teeth and more thrown material will be intercepted by the extra length of snout.

NUDGED LOG WILL NOT CONTACT SAW TEETH. EXTRA LENGTH OF SNOUT WILL INTERCEPT PORTION OF THROWN MATERIAL.

FIGURE 5: HOUSING USES LONGER SNOUT ON IN-GOING SIDE OF MOUTH WHERE ROTATING BLADE ENTERS HOUSING.

Tigercat

In figure 6a and 6b there is an additional opening in the housing skirt. Openings in this location are sometimes provided for escape of wood chips produced by the saw teeth in the cut and being taken into the housing.

FIGURE 6b

FIGURE 6c

FIGURE 6: ADDITIONAL OPENING IN THE HOUSING SKIRT.

In figure 6c a guard has been added to the chip escape port so that tangential travel of chips and other material is intercepted as soon as it leaves the housing.

Each figure shows a shaded area where normally tangentially thrown material can escape from the saw housing. Deflected and dropped chips escaping below the bottom edge of the housing skirt are not included. The areas and angles are not exact but do show that one head can be different from another.

It is important that the operator familiarize himself with the blade rotation direction, the effectiveness of any snout on the in-going side and which direction any chip escape ports allow material to fly.

Using high speed disc saws safely COMMENTS AND INSTRUCTIONS

Tigercat

Recognizing the Dangers While it may appear that these illustrated danger areas can be visually recognized on the job by observing how far chips fly during a cut, that is only true for chips and other light weight materials. Metal parts and wooden spears can be thrown to surprisingly greater distances. Even distant personnel on the ground, in other vehicles, or in buildings are at risk if the throw is in their direction.

Direction of throw The direction of possible tangential throw for metal parts and stones is dependent on the housing configuration and might be expected to be the same as observed for the chips. However, these throws can occur at any time the saw is running, in whichever direction the angle of throw is pointed by boom geometry, not just when a cut is being made.

Throw distance The throw distance for metal pieces and stones, can be many times the distance shown by the pattern for chips. More testing and data collection is needed to pin down a “safe distance” but if someone or something is in a place that can be seen by the operator and in the throw direction of a high speed disc saw, then the operation is not safe regardless of the distance.

Safe operating areas These saw heads must not be used in areas where the logging operation does not have control over the presence and movement of people. In particular, clearing of vegetation in urban and populated areas should not be done with a Tigercat manufactured or supplied high speed disc saw. High speed disc saw heads are intended for high productivity wood harvesting in areas remote from normal habitation. The possible presence of people and property within throw range and the likelihood of encountering scrap metal, wire fencing, steel posts and concrete must be respected.

Assessing the potential dangers on the job site The extent of danger from high speed disc saws on the logging operation has to be assessed on the job site, depending on how much other work activity is in the area and whether the operator can do his job of cutting and bunching with good control of throw patterns.

Danger is greater if the saw is equipped with detachable, or fragile, or brittle teeth, or if the site contains stones or abandoned metal.

Regular maintenance Poor saw maintenance increases these dangers. Some designs that might allow fasteners to wear thin or fatigue and suddenly break, need thorough timely replacement procedures. It is important that the warning signs of missing saw tooth parts or the sounds of striking rocks be heeded and the operation adjusted to avoid danger.

High angle wrist rotation ability When a felling machine is equipped with a high speed disc saw head with a high angle wrist rotation ability it should be determined that the limits of the boom, stick, tilt, wrist, upper leveling and any other freedoms, do not permit a direct throw at the operators cab during normal operation, see figure 7a. It is probably essential that the housing have a long snout on the throw side and that if a chip escape port is used it should be guarded.

With these high mechanical freedom arrangements there is a chance that an unforeseeable operator misadventure or equipment failure could result in an accidental direct or deflected throw at the operators cab, refer to figure 2 and 7b. The cab should be capable of resisting such accidental and ricochet throws. The velocity energy of metal or rock pieces leaving the blade is extremely high. The operators cab cannot be considered safe to routinely operate in the chip throw area, even if it has been especially constructed to prevent penetration by accidentally thrown objects.

Throwing long wood pieces Dangers from throws of long wood pieces are illustrated in figures 8 to 11. Tests and experience have shown that when a high speed rotating saw is applied to a loose piece of wood, the wood is either blown or pushed away, without a throw. If the wood is held firmly in all directions and the saw advanced into it at any feed speed, cutting will take place. If the wood is only held against escape from the saw radially, but not held tangentially, then the wood will be both partly cut and partly moved tangentially. In this last case tests have shown that if the piece of wood is backed-up by a solid slippery surface; and if the feed in is very fast; and if the piece of wood is long enough; then the tangential movement is a dangerous spear-like throw.

Figures 8 and 9 show two ways that this might happen in the woods if using the saw head of figure 4 (where the throw contact can be long). A slab, still partly attached to a well backed-up tree bole and wet with sap, makes an ideally bad throw situation which could unintentionally occur in woods work. A small log in a pile of other logs might also be propelled out with enough length of continued contact to reach near saw tip speed.

A SMALL LOG IN A PILE OF OTHER LOGS MIGHT ALSO BE PROPELLED OUT WITH ENOUGH LENGTH OF CONTINUED CONTACT WITH THE BLADE TO REACH NEAR SAW TIP SPEED.

Figure 10 shows how a head with snouts does not allow a long throw contact. Although tests show that a short contact length on a long log or tree butt does not result in a spear like throw, this action should nevertheless be avoided because abnormally large chips are sometimes produced and thrown.

Saw blade throw gap Saw blades have gaps between adjacent teeth and holders to permit installation and removal of the teeth and to provide spaces to accumulate chips in the cut, see figure 12. Fallen sticks and debris or sticks and debris sliding across the the saw blade can enter these gaps when the blade is rotating and be struck by the teeth and be tossed or thrown. Larger gaps and lower rotation speeds increase these dangers.

Saw housing entrance and exit space To avoid the ingestion of materials into the housing space above the disc (and later ejection) the ingoing entrance for the saw rim of teeth is kept as small as practical. It is important that this high wear area be maintained at its original size and shape. The outgoing opening is large enough to allow the housing to clean itself and will allow most things inside to be thrown out, see figure 13. Its throw direction and angle must be respected. A long snout on the other side reduces this danger.

THE INGOING ENTRANCE OF THE HOUSING FOR THE SAW RIM OF TEETH SHOULD BE SMALL

This information is offered by Tigercat as part of interim action to make saw heads safer. It is based on what has recently been reported from the field and on tests conducted on proving grounds. Tigercat is continuing to do design and testing of tree felling machinery towards achieving greater safety in the woods. Tigercat would be thankful for written reports describing any unsafe happenings, including near misses, in the use of felling heads and their carriers.

The following are some “SAW HEAD DON’TS” that apply particularly to throw prevention.

Do not point the throw of a disc saw head in a direction towards people, vehicles or buildings at any visible distance.

Do not operate in a way that throws chips in a direct-line at the machine cab.

Do not push hard with the saw against anything except a standing tree to be cut.

Do not mix new sharp teeth with old dull teeth on the same saw.

Do not change the blade rotation from its designed direction in the head.

Do not over speed the blade rpm.

Do not remove or shorten snouts provided by the head manufacturer or installer.

Do not neglect tooth fastening inspection, maintenance and replacement.

Do not neglect to repair worn or damaged saw housings.

Do not neglect to replace any covers removed for service or clean out.

Do not count on skis to give the throw protection that snouts do.

Do not nudge loose short pieces with the front of any type of head.

Do not nudge anything, even long logs, with the front of a head which has no snouts.

Do not cut short small stalks when blade speed is low.

Do not operate a high speed disc saw in a populated area.

Do not assume that visitors and other workers are aware of disc saw dangers.

Do not assume that the operator will spare you, a visitor, from danger.

Do not select and operate heads that throw rearward.

Each attachment on a multifunction machine has an attachment ID connector in the head that indicates to the controller which attachment is currently on the machine. The computer must be in the correct attachment mode to correspond to the attachment currently on the machine or the electronic system will not allow the pump to turn on. If the attachment mode DOES NOT correspond to the attachment on the machine a message will be displayed on the computer screen.

INSTRUMENT PANEL CONTROLS AND SWITCHES 5. CUTTER SWITCH - (SAW/MULCHER) 480-258

Use this switch to turn the saw/mulcher ON or OFF. This switch sends a signal to the controller, the controller then sends a signal to the cutter pump and valve to turn it on. The cutter icon on the computer display will turn green when either cutter is ON.

If at any time during operation the controller loses connection with the attachment ID connector, the cutter pump will turn off and a message will be displayed on the computer screen.

NOTE: Hydraulic and electrical hose connections for the attachment must be checked daily to ensure that they are tight.

In extreme conditions the connections must be checked more often. See Changing the Attachment and Hose Connections later in this section for details.

Controls and Operation

5B. CUTTER INDICATOR

Machine equipped with a saw: Ensure that the computer has been changed to SAW mode. Each saw installed on a multifunction machine is equipped with a saw blade speed sensor with intigrated attachment ID. When the correct mode is selected and the cutter switch (5) is turned on, the controller will stroke the pump to the correct flow and pressure required to run a saw. During operation of the saw, the controller will turn the cutter pump off and the following Critical message will appear on the computer screen if the:

SAW OPERATION: Ensure that the computer has been changed to SAW mode.

Each increment on the gauge represents approximately 1000 psi. During cutting operations the indicator value will rise as the blade slows down due to cutting, and fall as the blade speeds up. A 2/3 value or higher indicates that the blade has not attained full speed from the previous cut or has jammed.

Further cutting should be delayed until the indicator value falls below the 1/3 increment to prevent stalling the saw blade during the next cut. Below 1/3 the saw blade is at optimum cutting speed.

•

MULCHER OPERATION: Ensure that the computer has been changed to MULCHING HEAD mode. Each increment on the gauge represents approximately 1000 psi. The cutter indicator shows an increase in pressure the harder the Mulcher circuit is working. The indicator gauge will show 5/6 of full scale when it is working the hardest. Example: recovering from a static drum or mulching large objects.

If the mulching drum is running at full speed but not mulching anything, the indicator gauge should read below 1/3 of full scale..

saw blade exceeds its maximum allowable speed.

The following Alert message will appear on the computer screen if the:

Machine equipped with a mulcher: Ensure that the computer has been changed to MULCHING HEAD mode. If the Incorrect Attachment critical message appears change the computer setting to MULCHING HEAD mode.

NOTE: When the cutter is turned on with the engine speed below 1500 rpm or the hydraulic oil temperature below 38 °C (100 °F) the cutter pump will ramp on very slowly to avoid lugging the engine excessively or to avoid sending cold hydraulic oil to the mulching head motors at high pressure.

•

saw blade has been stalled (or pinned) for an extended period of time.

•

speed sensor signal wire has become disconnected.

NOTE: The Cutter pump will still function normally.

Controls and Operation FIRE DETECTION SYSTEM COMPONENTS The Fire Detection System consists of the following main components:

FIRE DETECTION SYSTEM NOTE: This system is for FIRE DETECTION ONLY, it is not a fire suppression system.

In no way does the installation of this fire detection system reduce the need to adhere to the guidelines given in the FIRE PREVENTION section of this manual.

WARNING LIGHT

The fire detection system is only a warning system and will not extinguish a fire. If a fire is detected it must be extinguished manually using certified fire fighting equipment.

SYSTEM OPERATION There are 3 thermostats mounted in the engine and hydraulic area that are connected to the computer control system. The thermostats are automatic heat detection devices and are set to “close” at 177°C (350°F). When a thermostat closes it sends a signal to the computer which activates an audible alarm, flashing warning light and a visual warning on the computer screen indicating that a fire has been detected.

This message will be displayed, alarm light will flash and alarm will sound when this engine has idled for more than 4 consecutive hours.

Shutdown engine to prevent damage to the emission control system.

1. Saw head is installed when in Mulcher mode or a mulching head is installed when in saw mode.

2. The attachment ID harness is not connected properly when attempting to turn the cutter on.

IMPORTANT !

Engine should not idle longer than 4 consecutive hours. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the SCR after treatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components. It will take 45 minutes at 40% load (or an SCR exhaust outlet temperature of 320°C (608°F)) to burn off the hydrocarbon that accumulates during a 4 hour long idle.

Symptoms: Cutter will not be allowed to turn on.

If the Cutter is already on and the harness to the attachment were to get damaged, the error will not show up until the cutter switch is turned off.

Cutter cannot be turned on again until the problem is addressed.

When DEF levels are low information messages and warnings will be shown on the computer display. Note that extremely low DEF levels may result in derating of engine performance to meet emission standard requirements. Action to correct DEF levels should be taken immediately to avoid affecting engine performance. Refer also to COMPUTER~MESSAGES AND WARNINGS in THIS SECTION.

DEF is used by the Selective Catalytic Reduction (SCR) after treatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust of this vehicle.

The DEF tank and DEF supply lines are heated when temperatures are low, the system will thaw DEF within 30 minutes of engine start for proper operation of the SCR after treatment system.

Note also that whenever the engine is stopped all DEF is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds. Refer to SELECTIVE CATALYTIC REDUCTION SYSTEM in SECTION 3 of THIS MANUAL.

When a problem with DEF quality is detected information messages and warnings will be shown on the computer display. Note that DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR after treatment system components. Refer also to COMPUTER~MESSAGES AND WARNINGS in THIS SECTION.

It is important to avoid contamination of DEF when filling the tank as this may cause costly damage to SCR system components and affect the proper operation of the SCR system and the engine.

Diesel exhaust fluid (DEF) is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water. Note that DEF may also be referred to as AUS32 or AdBlue and should meet ISO 22241 specifications. Use only DEF meeting this standard.

IMPORTANT! DEF should be stored between -11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

Refer also to SELECTIVE CATALYTIC REDUCTION SYSTEM in SECTION 3 of THIS MANUAL for more information regarding the use of DEF and its function in the SCR after treatment system.

WARNING Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. DEF fluid is sprayed into the exhaust system at high temperatures during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

• ENGINE EQUIPPED WITH HEATER STARTING AID.

IMPORTANT !

• USE OF ETHER COULD RESULT IN DEATH OR SERIOUS INJURY.

Engine should not idle longer than 4 consecutive hours. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the SCR after treatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components. It will take 45 minutes at 40% load (or an SCR exhaust outlet temperature of 320°C (608°F)) to burn off the hydrocarbon that accumulates during a 4 hour long idle.

CARE OF POLYCARBONATE WINDOWS IN CAB

•

(Windshield, skylight and three rear windows) Most windows used in the cab are made from a polycarbonate resin thermoplastic. This material is a replacement for glass when improved strength, durability and safety is required.

Polycarbonate material is expected to resist heavy impact from large branches and falling tree tops and to absorb high levels of energy when contacted by high velocity thrown objects such as wood chips, disc saw blade teeth or broken harvester head saw chain.

The extreme operating environment seen in logging applications heightens the need to regularly inspect and properly maintain polycarbonate cab windows.

Polycarbonate windows are an essential piece of operator protective equipment and should be maintained as such. It is important to note that cracks, chips, notches or scarring anywhere on the viewing surface or edges of the window will decrease ability to resist heavy impacts and therefore compromise effectiveness as operator safety protective equipment. Windows with these defects must be replaced immediately.

Refer to the next section for detailed information regarding inspection and maintenance of polycarbonate windows.

• • •

•

Cracks, chips, notches or scarring anywhere on the viewing surface of the window will decrease ability to resist heavy impacts.

Windows with these defects must be replaced immediately.

Bent, dented or missing window retaining parts must be replaced immediately.

Rubber materials used in mounting the window must be maintained in good condition.

Identification of the polycarbonate originally used by Tigercat is hot stamped in a corner of the window to identify its composition. Do not use any replacement window without proof of its material composition. Do not substitute with any other materials.

Skylights, cab structures, windows and window retaining parts must not be modified or replaced with components that are not approved by Tigercat.

RESISTANCE TO CHEMICALS The resistance of polycarbonate material to chemical exposure varies widely. Fortunately, polycarbonate materials have good resistance to diesel fuel, grease, hydraulic oil, kerosene and engine oil.

Other chemicals however can seriously weaken the polycarbonate.

DO NOT permit any of the following chemicals to come into contact with polycarbonate windows: • acetone • air conditioning refrigerant • ammonia • anti-freeze • benzene • brake fluid • carbon tetrachloride • cutting oils • gasoline • lacquer thinner • toluene • turpentine • xylene RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

INSPECTION AND MAINTENANCE Daily inspection and maintenance is essential to confirm that the window’s ability to protect the operator has not been compromised.

• Inspect all windows daily and immediately after any impacts.

• Check for any damage to the window material or steel structure in the area of the window mounting.

• The edges of the polycarbonate window must be evenly and fully supported on a flat surface around the entire window opening at all times.

Bent or dented skylight structures must be replaced immediately. Bent or dented cab structures must be evaluated immediately for possible repair or replacement.

• The edges of the polycarbonate window must be free from cracks, chips, notches or scarring and must not be pinched or stressed.

These defects will decrease ability to resist heavy impacts. Windows with these defects must be replaced immediately.

2.85

Tigercat M726E Mulcher

Controls and Operation

Exposing polycarbonate to repeated steam cleanings or high temperature pressure washing may result in crazing, a phenomenon that causes clouding of the surface. Crazing can ultimately result in a loss of physical strength and may precede a fracture.

CLEANING INSTRUCTIONS The viewing surfaces of polycarbonate cab windows are specially treated with a hard coating to provide enhanced resistance to abrasion and ultra-violet (UV) radiation.

The following instructions are provided to prolong the life of this protective hard coating.

•

DO NOT use brushes, razor blades, scrapers, squeegees or other sharp tools on polycarbonate windows.

•

DO NOT clean polycarbonate windows when the daytime temperature is high or in direct sunlight.

•

DO NOT use abrasive or highly alkaline cleaners on polycarbonate windows.

•

DO NOT use glass cleaners in either aerosol or non-aerosol containers to clean polycarbonate windows.

•

Failure to follow these cleaning instructions will shorten the service life of polycarbonate and may cause visual hazing, loss of light transmission and delamination of the polycarbonate hard surface coating.

1. Rinse the window thoroughly with lukewarm water 2. Using a soft cloth, cellulose sponge or chamois, gently wash the window with a mild solution of soap or detergent in lukewarm water. Do not scrub or use brushes or squeegees.

CONCEALING HAIRLINE SCRATCHES The appearance of scratches and minor abrasions on the surfaces of polycarbonate windows can be minimized by using a mild automotive polish such as:

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik • Formula 409 • Hexcel F.O. 554 • Joy • Lysol • Mr. Clean • Neleco-Placer • Pine-Sol • Top Job

• • •

Be certain to clean the polycarbonate window as outlined prior to application of an automotive polish. Refer to CLEANING INSTRUCTIONS. GRAFFITI REMOVAL •

For removal of paints, marking pen inks, etc., the use of Butyl Cellosolve is generally effective. The use of masking tape, adhesive tape or lint removal tools works well for lifting off old weathered paints.

•

To remove labels, stickers, etc., the use of kerosene, VM&P Naphtha, or petroleum spirits is generally effective. When the solvent will not penetrate sticker material, apply heat (hair dryer) to soften the adhesive and promote removal.

3. Rinse the window thoroughly with lukewarm water.

4. Dry the window with a moist soft cloth, cellulose sponge or chamois to prevent water spotting.

5. To remove grease or oil, first rub lightly with a good grade of VM&P Naphtha or isopropyl alcohol followed by the same rinse, wash, rinse and dry procedure described in steps 1 to 4.

Refer also to RESISTANCE TO CHEMICALS for a list of chemicals which should not be permitted to come into contact with polycarbonate windows.

Refer also to RESISTANCE TO CHEMICALS for a list of chemicals which should not be permitted to come into contact with polycarbonate windows.

FIRE PRECAUTIONS

CAUTIONS •

Johnson’s Paste Wax Novus Plastic Polish #1 and #2 Mirror Glaze Plastic Polish

Polycarbonate window material will ignite when exposed to an ignition source in excess of 427°C (800°F). When working around polycarbonate windows, observe similar fire precautions to those in place for wood.

DO NOT use abusive cleaning procedures either by hand or pressure washing on polycarbonate windows.

The ¾” (smaller) couplers have a “Fully connected” line. Ensure that the end of the coupler is even with this line. The 1 ¼” (larger) couplers should be threaded on by hand until they bottom out. All couplers will be sealed in this position, but debris and vibration may bump them loose. All couplers should be tightened just past hand tight by tapping them lightly with a hammer to ensure that they remain tight. When attaching mulcher hoses, it is easiest to attach the large 1 ¼” couplers first.

TIGERCAT OIL SAMPLING PROGRAM Using the Tigercat Advanced Oil Analysis Program on a regular basis is an excellent preventative maintenance tool. Oil sampling cost is at the owner’s expense, however, studies have shown that it is possible to receive a 10 to 1 payback when looking at the amount saved on repair costs to the amount invested in a scheduled oil analysis program. Some of the benefits of a sampling program include: •

Detect problems early before they become major catastrophic failures.

•

Better ability to schedule downtime and forecast cost of repairs.

•

Monitor maintenance schedules and practices and confirm that the required maintenance is being done on time.

•

Increase used equipment value by providing proof of proper maintenance.

This Program uses the most modern technology available to analyze all oil samples. Most test results are available within 24 hours after receipt of the sample and are supplied in an easy to understand report, which calls for specific action and makes detailed recommendations. This report is available as a mailed or faxed hardcopy, sent via e-mail or can be viewed on the internet.

This program will provide Tigercat machine owners access to an Advanced Oil Analysis Program for all major machine components including powertrain components, specifically hydrostatic pump and motors, boom/steer pump, axles, transfer case, pump drive gearbox, etc.

Refer also to OIL SAMPLE COLLECTION PROCEDURES in THIS SECTION for sample valve and drain plug locations.

TIGERCAT OIL ANALYSIS KITS Each kit includes a Pre-paid Sample Bottle and Sample Information Form. Pre-printed mailing labels are also included to ensure all samples are quickly returned directly to the lab for immediate analysis and results within 24 hours of receipt.

The same type of sample bottle can be used for all types of oil testing including: Hydrostatic pump and motors, boom/steer pump, axles, transfer case, pump drive gearbox, etc.

To ensure accurate and meaningful results are obtained, each kit also includes detailed instructions on how to properly collect, prepare and ship the oil samples.

Contact your Tigercat Dealer Parts Department to order Kits.

TIGERCAT OIL SAMPLING PROGRAM OIL SAMPLE COLLECTION PROCEDURES

OIL SAMPLING CONNECTOR

Fill out the Sample Information Form (SIF) completely and accurately. When taking multiple oil samples, fill out all of the required SIF forms in their entirety, prior to taking any oil samples. Then, immediately package each completed SIF form together with the matching oil sample in the black outer shipping container as each individual sample is taken. This will reduce the possibility of mixing up or incorrectly identifying the SIF forms and oil samples. Incorrectly identified samples could result in a false warning alarm.

The accuracy of the lab analysis results is very dependent on the quality of the oil sample taken. Collection of clean oil samples that are representative of the main body of oil are essential if meaningful lab results are to be obtained.

Erroneous readings may result if proper collection, handling, packaging and shipping practices are not followed prior to the sample being tested by the lab. To be able to accurately compare and trend the lab results over time, all follow-up samples should be consistently taken from the same location using the same techniques as all previous samples.

•

Ensure that all sample valves and drain plugs are clean and free of debris.

•

Remove the sample bottle cap only when ready to take the sample. Keep the cap clean – do not put it in your pocket or let it get contaminated in any way.

•

Do not allow any airborne dirt, etc. to enter the sample bottle.

•

Avoid contamination of the sample – replace the sample bottle cap immediately after filling the bottle to approximately ¾ full. All samples taken should be immediately forwarded to the lab for processing.

Contact your Tigercat dealer to purchase additional or replacement hydraulic sample valves or drain plugs.

In cases where oil samples must be pumped or otherwise drawn out of a reservoir or housing, a hand operated oil suction pump is also available from your Tigercat dealer.

WATER ABSORBING ELEMENT (COLOR BLUE) M726E-110

HYDRAULIC OIL RETURN FILTERS

Hydraulic Oil Samples: • Hydraulic oil samples should be taken from the circulating oil flow at operating temperature, with no functions actuated, using sample valves that are permanently located on the machine whenever possible.

•

To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of 3 or 4 ounces of oil into a separate container and discard this oil using approved recycling methods.

•

Replace the dust cover on the sample valve immediately after taking the oil sample and sealing the sample bottle.

Transmission, Axle and Pump Drive Gearbox Samples: •

These samples can be taken during the oil change process.

•

To obtain a representative oil sample, ensure the oil is warm and has not settled very long (within 30 minutes of shutdown).

•

Place the required drain container under the machine to capture the used oil to be discarded using approved recycling methods.

•

Remove the drain plug and allow approximately 50% of the oil to drain, then place the sample bottle in the stream of draining oil to obtain a representative sample.

Lubrication and Maintenance

GENERAL CAUTION All handles, steps and platforms must be kept free of grease, oil, fuel, mud, snow, ice and forest debris to prevent risk of personal injury. þ Clean around filler caps before checking or adding fluids. þ Clean around hydraulic fittings before breaking connection. Plug or cap immediately. þ Clean up spills as soon as possible. þ Always use clean hydraulic oil and filters. þ Drain dirty oil while still warm. þ Do not exceed recommended fluid levels. þ Service all hydraulic filters after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system. þ Top up diesel fuel at end of each shift to reduce contamination by condensation. þ Clean up oil spills on walking surfaces and top of engine enclosure immediately. þ Inspect the EXHAUST SYSTEM DAILY for any signs of LEAKAGE. Check for worn, cracked, broken, or damaged pipes or muffler.

Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, DO NOT OPERATE the machine until the exhaust leak is repaired.

þ During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed. þ Before welding on machine be sure master switch is disconnected and disconnect multi pin connectors on engine CPU and engine wiring harness. þ When welding secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings. þ Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires. þ Always have a fire extinguisher at hand. þ For safety, always lower boom assembly to the ground when leaving cab, leaving machine unattended or during service. þ For safety, when working under boom, always lower to ground, support properly or install lift boom cylinder locking device .

GENERAL CHECK FIRE EXTINGUISHER, DAILY:~

FIRE PREVENTION Maintaining your machine properly will greatly extend its life and reduce your operating costs.

Fire can result in a machine loss which can be financially devastating.

CAUTION

CHECK CHARGE GAUGE DAILY

AFTER transporting (trucking) a machine from one job sight to the next, open all doors and access panels and blow off any debris that could have re-positioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

1. Forest debris and fine organic material (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

2. Pay close attention to wiring and plumbing routings during maintenance, ensure that ALL wiring harnesses or hydraulic hoses are properly restrained and clamped to prevent damage from chaffing.

3. If equipped, read the fire suppression system manual and have the system serviced regularly by qualified personnel.

4. In case of fire lower the boom system to the ground and shut off the engine before discharging the fire suppression system.

Also refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL for additional information.

A portable fire extinguisher is located in operator's cab. The extinguisher should be checked daily to ensure that it is charged. The pointer on the charge gauge should point to the green region.

If the indicator falls out of this green area, the extinguisher should be serviced immediately.

Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. Refer to the manufacture's Use and Information manual for proper usage, additional information and recommended inspection and maintenance intervals.

Lubrication and Maintenance FUEL FILTER AND FUEL FILTER/WATER SEPARATOR The fuel filter is supplied with the engine. Refer to the engine manufacturer's operation and maintenance manual for service information and replacement interval.

The fuel filter/water separator is a combination unit, with a replaceable fuel filter and a removable water sediment bowl on the bottom of the unit.

The water sediment bowl is only replaced if it becomes damaged or non-functional. For service and replacement intervals see SERVICE AND LUBRICATION POINTS in THIS SECTION. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended that the fuel/water separator bowl be drained daily.

When installing a new fuel filter, DO NOT pre-fill with diesel fuel, or engine fuel pump damage will result. This type of failure is not warrantable by the engine manufacturer.

Unfiltered fuel used to pre-fill filters enters directly into the fuel system. Contaminants in unfiltered fuel can cause significant and costly damage to the engine. The cleanliness of fuel cannot be guaranteed unless it is always pre-filtered before use.

IMPORTANT! Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the engine manufacturer's operation and maintenance manual.

For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION.

Changing the filters:

There is a bypass valve built into each filter head preset at 25 psi (1.7 bar), which will open in the event the elements become restricted. Before this valve is activated, a 20 psi (1.4 bar) filter restriction switch, located on the return manifold, will generate a critical message on the computer screen.

3. Place rags below to catch the spillage of oil.

1. Park machine on level ground, install articulation lock bar, lower attachment to ground, stop engine, engage parking brake and block wheels.

2. Wipe clean the area around the filter and head.

480-017

M726E-073

The engine air precleaner cleans engine air before it reaches the air cleaner filter elements. It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance.

However, it should be checked periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

NOTE: The precleaner compartment should be checked and cleaned out daily to ensure proper operation of the precleaner.

NOTE: Periodically remove the precleaner assembly and check the spinner assembly for wear or dirt build-up on the blades. Clean the spinner assembly or replace it if the blades are worn.

1. Dirty air (1) enters the Precleaner, which is clamped onto the engine air intake.

2. Specially-designed vanes (2) , curved and angled to precisely direct air flow, move the dirty air toward the stainless steel impeller (3).

3. The dynamically balanced, one piece impeller (3) (only moving part) creates a tornado inside the housing.

4. The centrifugal force of the tornado expels the heavier than air dirt particles (4), chaff, dust, snow, rain, etc., out the discharge louver 5. Cleaned air (5) enters the engine air cleaner intake pipe, and the filter element has only the very light particles to remove.

RESULTS • Cleaner Air for The Engine!

• Longer Filter Element Life!

• Increased Engine Life!

• Increased Engine Performance!

• Reduced Operating Costs!

AIR CLEANER UNLOADER VALVE

The most common and damaging servicing problems are: OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks dirty may actually be more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

UNLOADER VALVE

NOTE: This does not apply to hydraulic oil or diesel engine oil filters.

SERVICING Engine exposure to dust during servicing is a large reason for engine damage due to dust.

M726E-076

This rubber valve on the tube of the air cleaner housing should be checked before every shift (8 hours). If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should suck closed at 1/3 throttle.

Abrasive dust can easily enter the intake system once the air cleaner cover and protective filter element are removed for replacement. The safety element does reduce this risk but it should also be replaced at every third primary element change.

This valve should be replaced every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing. Check and clean the valve.

A good valve is soft and flexible. If plugged, be sure to check the filter elements as they may need replacing as well. Reattach the valve to the tube.

When operating in high dust conditions, the unloader valve should be checked and squeezed every 2 hours to release dust buildup.

SAFETY ELEMENT

Replace all air intake rubber components such as elbows and connectors every 2000 hours - High temperatures in this area can cause the rubber to harden.

PRIMARY ELEMENT 470-04

AIR FILTER ELEMENTS

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Release the six overcenter latches and lift cover/dust bowl off of air cleaner assembly .

2. Avoid dislodging dust from filter element(s) by gently pulling the element off the outlet tube.

3. Always clean the sealing surface of the outlet tube before inserting a new filter element.

4. Always clean the inside of the outlet tube.

5. Check your old filter sealing surfaces. This will help you detect foreign material on the sealing surface that is causing leakage.

NOTE: Filter elements should never be cleaned and reused. Cleaning causes dust to bypass the filter and be deposited on the inner surface of the filter media. The dust is then drawn directly into the engine.

6. Inspect the new filter for damage.

7. Insert the new filter properly. Apply pressure to the outer rim of the filter not the flexible centre.

8. Check connections and ducts for an air tight fit.

Ensure that all clamps, bolts and connections are tight. Check rubber elbows intake tubing and joints for hardening cracks, splits or wear points and replace as needed. Leaks in these locations send dust directly to the engine.

SELECTIVE CATALYTIC REDUCTION AFTER TREATMENT SYSTEM (DENOX 2 SYSTEM)

The SCR after treatment system consists of the following components:

The engine on this machine is equipped with a Selective Catalytic Reduction (SCR) after treatment system to limit the nitrogen oxide exhaust gas values (NOX) to meet Tier 4i emission standard requirements with low fuel consumption.

This process is electronically controlled by the DENOX 2 system.

The SCR process is based on series of chemical reactions which involve the reaction of ammonia with the oxygen in the exhaust gas to reduce nitrogen oxides (NOX) in the exhaust gas by transforming it into inert compounds: free nitrogen (N2) and water vapour (H2O).

470-040

The supply module pump picks up the DEF solution from the tank and sends it under pressure to the dosing module (DEF injector) and mixer tube to be injected into the exhaust pipe upstream of the catalytic converter.

The first phase of the process takes place in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust fumes and ammonia at the proper reaction temperature, are introduced into the catalytic converter, where the second phase of the process takes place: by reacting with the oxygen in the exhaust gases the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

NOTICE

• DO NOT IDLE THIS ENGINE FOR MORE THAN 4 HOURS. • DAMAGE TO EMISSION CONTROL SYSTEM WILL RESULT.

59912BENG R0

IMPORTANT !

Engine should not idle longer than 4 consecutive hours. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the SCR after treatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components. It will take 45 minutes at 40% load (or an SCR exhaust outlet temperature of 320°C (608°F)) to burn off the hydrocarbon that accumulates during a 4 hour long idle.

HEATER UNIT

Diesel exhaust fluid (DEF) is used by the Selective Catalytic Reduction (SCR) after treatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust of this vehicle. DEF is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water. Note that DEF may also be referred to as AUS32 or AdBlue and should meet ISO 22241 specifications. Use only DEF meeting this standard.

DEF tank capacity is 43 L (11.4 US gal). DO NOT overfill tank. This tank is equipped with an expansion capacity of 7% required to allow for the expansion of DEF in cold temperature conditions.

DEF freezes at -11°C (12°F).

It is important to avoid contamination of DEF when filling the tank as this may cause costly damage to SCR system components and affect the proper operation of the SCR system and the engine.

IMPORTANT! DEF should be stored between -11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

A DEF level indicator is shown on the main menu of the computer display, below the fuel gauge.

WARNING Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. DEF fluid is sprayed into the exhaust system at high temperatures during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

NEVER fill the DEF tank with any other fluid.

Doing so may cause a fire risk which could result in death or serious injury.

The DEF tank includes a fill location, a drain, and a heater unit. The heater unit incorporates a heater coil, heating system inlet/outlet connections, DEF inlet/outlet connections, a breather, level sensor, temperature sensor and electrical connector.

When DEF levels are low or a problem with DEF quality is detected information messages and warnings will be shown on the computer display.

Note that extremely low DEF levels and/or DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct these problems should be taken immediately to avoid affecting engine performance and damage to SCR after treatment system components.

The catalytic converter is equipped with soundproofing material and replaces the exhaust silencer. Chemical reactions inside the catalytic converter reduce nitrogen oxides (NOX) in the exhaust gas.

The first phase of the SCR process takes part in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust fumes and ammonia at the proper reaction temperature, are introduced into the catalytic converter, where the second phase of the process takes place: by reacting with the oxygen in the exhaust gasses the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

DOSING MODULE

MIXER TUBE

The dosing module is mounted on the mixer tube upstream of the catalytic converter. The dosing module injects DEF fluid into the exhaust pipe.

Note that this module must be mounted at the correct specified angle to function properly.

MIXER TUBE The mixer tube is mounted on the exhaust pipe upstream of the catalytic converter.

The insulated high-turbulence mixer tube is used to mix the DEF solution and exhaust gases together before they enter the catalytic converter.

EXHAUST TEMPERATURE SENSORS

The sensor, cable and control unit are considered to be one part for service/replacement purposes.

Note that cable length cannot be changed as this will affect the proper operation of the sensor.

TAG

IMPORTANT! When checking or replacing any sensor or plugs in the exhaust or the after treatment system it is important to use only approved anti-seize as specified by Tigercat. Use of nonapproved compounds can affect the operation of the NOX sensor and a malfunction of the SCR after treatment system. This may result in poisoning of the catalytic converter and require replacement of expensive after treatment system parts.

620E-087

EXHAUST TEMPERATURE SENSOR

Temperature sensors are mounted at the inlet and outlet of the catalytic converter. These sensors send inlet and outlet exhaust temperature signals to the Denox DCU. The DCU uses this information to calculate the amount of DEF fluid to be injected into the system.

Refer to APPROVED ANTISIEZE PASTES FOR EXHAUST / AFTER TREATMENT LINE (TIGERCAT BY FPT Tier 4i ENGINES) in SECTION 3 of THIS MANUAL. HUMIDITY SENSOR

Note that to distinguish between inlet and outlet temperature sensors the inlet exhaust temperature sensor has a black tag and the outlet exhaust temperature sensor has a brown tag.

NOX SENSOR ELECTRONIC CONTROL UNIT

620E-089

The humidity sensor is located on the air intake just past the air cleaner. This sensor monitors the temperature and humidity of intake air sending signals to the engine ECU and Denox DCU. This information is used to calculate the amount of DEF fluid to be injected into the system.

CERAMIC SENSOR

620E-088

HUMIDITY SENSOR

NOX SENSOR

The NOX sensor is mounted at the outlet of the catalytic converter. The NOX sensor detects and sends information about the dosing of DEF solution and the efficiency of the catalytic converter to the engine ECU and the Denox DCU. This information is used to to calculate the amount of DEF fluid to be injected into the system and to monitor SCR after treatment system operation.

The NOX sensor consists of ceramic sensor and an electronic control unit linked by a cable. The sensor detects the concentration of nitrogen oxides in the exhaust.

When checking or replacing any sensor or plugs in the exhaust or the after treatment system it is important to use only approved anti-seize as specified by Tigercat.

Use of non-approved compounds can affect the operation of the NOX sensor and a malfunction of the SCR after treatment system. This may result in poisoning of the SCR catalyst and require replacement of expensive after treatment system parts.

DIESEL EXHAUST FLUID (DEF) HANDLING Diesel exhaust fluid (DEF) is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water. Note that DEF may also be referred to as AUS32 or AdBlue and should meet ISO 22241 specifications. Use only DEF meeting this standard.

It is important to avoid contamination of DEF as this may cause costly damage to SCR system components and affect the proper operation of the SCR system and the engine.

When a problem with DEF quality is detected information messages and warnings will be shown on the computer display. Note that DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR after treatment system components. Refer also to COMPUTER~MESSAGES AND WARNINGS in SECTION 2 of the OPERATOR'S MANUAL or SECTION 6 of the SERVICE MANUAL.

AVOID DEF QUALITY PROBLEMS WITH PROPER HANDLING PRACTICES Most DEF quality problems can be avoided entirely with a little care and proper handling of DEF fluid.

FILLING THE DEF TANK •

Always clean the area around the fill cap and avoid introducing contaminants into the DEF tank when filling.

•

Always use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. Use of any other fluid will contaminate the after treatment system and may pose a safety hazard.

USE OF PROPER STORAGE CONTAINERS •

To prevent contaminants from affecting DEF quality it should be handled only in storage, transport and filling containers intended exclusively for that purpose.

•

Polyethylene or stainless steel containers are recommended. Refer also to DEF manufacturer's recommendations.

•

DEF is corrosive to metals other than stainless steel. Transport in metal containers other than stainless steel will result in contamination.

PROPER STORAGE CONDITIONS TO MAXIMIZE SHELF LIFE •

DEF should be stored between -11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

•

DEF quality problems can often be avoided with proper storage and handling practices to maximize shelf life.

•

DEF storage areas should always be out of direct sunlight and away from heat sources to avoid reducing shelf life.

•

DEF shelf life is limited. It should be consumed on a first in first out basis, within manufacturer's recommended shelf life limits.

DEF beyond manufacturer's recommended shelf life limits may not meet ISO 22241 specifications.

For safety information refer to DIESEL EXHAUST FLUID (DEF) in SECTION 1 of THIS MANUAL.

WARNING Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. DEF fluid is sprayed into the exhaust system at high temperatures during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

NEVER fill the DEF tank with any other fluid.

Doing so may cause a fire risk which could result in death or serious injury.

FAN CONTROL ELECTRONIC CONTROLLER

The temperature sensor in the hydraulic tank operates in a similar manner to the engine coolant temperature sensor but independently and with a different temperature range. This temperature range depends on the type of hydraulic oil used.

This sensor will signal the electronic control module to turn the fan ON at the minimum set point temperature. As the temperature of the hydraulic oil increases, the speed of the fan will also increase to a maximum 2200 rpm fan speed @1850 rpm engine speed, at this point the temperature of the hydraulic oil will be at the maximum set point or higher.

COOLING SET POINTS

Charge Air Min 60°C (140°F) Charge Air Max 82°C (180°F) Engine Coolant Min 84°C (183°F) Engine Coolant Max 95°C (203°F) Hydraulic Oil Temp values depend on type of oil used.

ELECTRONIC CONTROLLER

This control consists of an electronic processing module, a three position FAN switch in the operator's cab with CLEAN/AUTO/FULL ON* positions for fan control.

FAN SWITCH

When the switch is in the AUTO position and the fan is stopped due to low engine coolant, air intake or hydraulic oil temperatures, turning ON the A/C will immediately turn the cooling fan to run at 1200 rpm. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

CAUTION M726E-044

Before placing the fan switch in the CLEAN (PURGE) position make sure that there are no personnel on the left side of the machine in the area where the fan will expel debris

CONTROL PANEL FULL ON AUTO CLEAN

M726E-131

When the engine coolant temperature reaches 84°C (183°F) the sensor on the engine in conjunction with the electronic control module will send a signal to the control valve to start to turn the fan slowly. The fan speed is variable from zero up to a maximum of 2200 rpm fan speed @1850 rpm engine speed. As the temperature of the coolant increases so does the speed of the fan up to the maximum 2200 rpm fan speed @1850 rpm engine speed. At this point the engine coolant temperature will be 95°C (203°F), or higher.

When the switch is in the FULL ON (OVERRIDE) position, the fan will run at FULL speed for cooling regardless of coolant, air intake or oil temperatures. The AUTO CLEAN/REVERSE feature will not function in the FULL ON position.

When the switch is pressed momentarily to the CLEAN (PURGE) position, the control module will signal the control valve to reverse the flow of oil to the motor and turn the fan in reverse. The control module will also turn the air conditioning system OFF for as long as the fan switch is in the CLEAN (PURGE) position.

See COMPUTER, GENERAL SETTING to make adjustments to FAN PURGE INTERVALS and FAN PURGE LENGTH in SECTION 2 of the operator's manual.

Assembly Torque The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts. The flat surface of the port compresses the O-ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head on to the flat surface of the port compressing and trapping the O-ring in the groove and leaving no gap for it to extrude under pressure. The hydraulic pressure is thus sealed by the compressed O-ring as long as the bolts are tightened enough to maintain solid metal to metal contact between the flange head at the outside diameter of the O-ring and the top of the port.

The 4-Bolt Split Flange consists of four main components: • A body (flange head) • An O-ring • One “captive” or two “split” flange clamps

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly

FLANGE HEAD

The steps to properly assemble the flange port clamping bolts are: 1. Make sure sealing surfaces are free of burrs, nicks, scratches or any foreign particles.

2. Lubricate the O-ring.

3. Position flange and clamp halves.

4. Place lock washers on bolts and insert through clamp halves.

5. Hand tighten bolts.

6. Torque bolts in diagonal sequence (see Fig. T9) in small increments to the appropriate torque level listed in Table T6 or Table T7 on this page.
