Safety

SAFETY HAZARDS – VITON SEALS

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.

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

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 12 mm (1/2 in) for each addition 1,000 volts above the 50,000 volt level.

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

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

•

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.

Visually inspect any seals or gaskets which have suffered from heat; they will appear black and sticky. If these are found, Do Not Touch!!!

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to Vehicle Moving Instructions page in SECTION 2 of the OPERATOR'S MANUAL.

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.

•

Wear disposable heavy duty gloves (neoprene) and decontaminate the affected area by washing thoroughly with limewater (Calcium Hydroxide solution).

•

Safely discard any cloths, residue and gloves after use.

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 5 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

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.

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

FLUID INJECTION INJURY

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.

WARNING 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.

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.

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.

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.

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

•

Seek professional medical attention immediately.

1.16

•

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.

•

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.

SERVICING SAFETY PRECAUTIONS Continued 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.

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.

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

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.

Tigercat 234B Loader 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 • Monitor daily weather forecasts

WHAT IS A LIGHTNING STRIKE?

• Observe local weather conditions

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.

• 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 mi). 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 ft) 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 234B Loader

Safety WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER. If you can, get inside.

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

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

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

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.

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

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.

• 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 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.

• 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.

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.

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

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

Safety

Tigercat 234B Loader 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. Lightning is probably about to strike. You only have a few seconds to act.

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. 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.

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

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

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

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.

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

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

2. Call your local emergency response telephone number immediately.

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

3. If the victim has no pulse, their heart has stopped or they have stopped breathing.

Start CPR or mouth-to-mouth resuscitation immediately. Use a portable defibrillator if one is available.

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

6. Avoid entering any small enclosures or shelters.

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.

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.

To further increase your awareness about lightning safety, see the following web sites.

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

National Weather Service Lightning Safety http://www.lightningsafety.noaa.gov National Lightning Safety Institute http://www.lightningsafety.com

10. Stay at least 5 m (16 ft) 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.

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

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.

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.

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

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.

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

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

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

1. Maintain a charged fire extinguisher on the machine at all times and KNOW HOW TO USE IT.

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.

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 COOLER PACKAGE in SECTION 2 of the OPERATOR'S MANUAL.

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.

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.

11. Park the machine at least 15 m (50 ft) 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.

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

1.21

Safety

Tigercat 234B Loader

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

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

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

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

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.

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.

1.22

•

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

4. Radio or call for help. Be certain to report a fire immediately.

5. Exit the machine taking fire extinguisher and pressurized water system hose (if applicable) with you.

Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

6. At all times ensure your own personal safety and the safety of anyone that may be in the area. Approach any fire with extreme caution.

All fires can be very dangerous and life threatening.

Ensure that you follow all national, state / provincial and local regulations dealing with fire fighting in effect in your specific geographic region. Regulations will vary from region to region but most will usually require that:

7. Only if you can safely do so, turn OFF the battery disconnect switch.

Before deciding to fight the fire, be certain that.

Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

1. The fire is small and not rapidly spreading.

2. There is always a clear, safe escape route to your back.

Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

3. You have received training in the use of the available fire extinguishing systems and are confident that you can operate them effectively.

Whenever portable fire extinguishers are provided for use in the workplace, training must be provided to familiarize workers with the general principles of fire extinguisher use and the hazards involved with fire fighting.

4. If in any doubt about whether or not to fight the fire – DON’T. Instead stand well clear of the fire and wait for help to arrive.

Training must be provided upon initial employment and at least annually thereafter.

•

Ensure that all information necessary for you to immediately contact all sources of help (local fire department, etc) in the event of a fire emergency is recorded and readily available at all times.

5. Be aware that engine coolant , diesel fuel or hydraulic hoses could fail during a fire. If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system on your machine.

There is not enough time available to read instructions during a fire emergency.

6. If possible a dry chemical fire extinguisher or fire suppression system** should be used first to fight a machine fire. Then immediately afterwards use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available). A fire suppressed by dry chemical may re-ignite from the heat retained by any debris or hot machine components in the area. The water will cool the area, reducing the chances of re-ignition.

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.

FIRE PREVENTION Continued DRY CHEMICAL CLEANUP PROCEDURES

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.

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.

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.

3. THROTTLE CONTROL

4. INTERLOCK RESET SWITCH

This is a three position 'momentary' switch connected into the engine CPU circuit to adjust the engine rpm between the (IDLE) and (FULL) throttle set points.

This function is provided to prevent accidental or improper use of the controls from anywhere but the operators seat.

With the engine running and the LH arm rest DOWN, push this switch to REACTIVATE the interlock system after it has been deactivated by raising the LH arm rest, or by turning the Key switch to the OFF position.

NOTE: Engage the interlock reset to increase engine speed. When the system is deactivated the engine speed will reset to minimum rpm.

PRESS and HOLD this switch in the position to increase engine speed (rpm).

Release switch at desired rpm or continue to HOLD to place engine at the correct FULL throttle setting.

PRESS and HOLD this switch in the position to decrease engine speed (rpm).

Release switch at desired rpm. or continue to HOLD to place engine at the correct MINIMUM throttle setting.

NOTE: All operations should be performed at FULL throttle.

Maintaining Correct Engine rpm 234-089

It is most important that the IDLE and FULL rpm of the engine be correct at all times:

LH ARMREST SHOWN IN UP POSITION

5. INTERLOCK LIMIT SWITCH When the LH arm rest is placed in the UP position, a limit switch shuts OFF the interlock system DEACTIVATING all operating functions. When the LH arm rest is placed in the DOWN position, the limit switch closes and turns the interlock system ON. The operating functions are not REACTIVATED until the INTERLOCK RESET switch is pressed.

IDLE - 1000 - 1250 rpm (No Load) Factory Default is 1200 rpm FULL - 1600 to 2200 rpm max. (No Load) Factory Default is 2000 rpm RATED WORKING — ­ 2200 rpm NOTE: At start-up the engine will always default to IDLE. The above values are with the hydraulic and engine oil at normal operating temperatures and no functions activated. These values are pre-set into the engine CPU (computer) and cannot be adjusted without the proper electronic programming software equipment.

Auto Idle Down If the engine is set to run at full throttle and no functions are activated for 10 seconds, the engine will idle down. The engine will return to the set idle speed as soon as a function is activated.

The All button should be used to ensure that each stabilizer is applying equal pressure to the ground prior to operating the loader or lifting any loads.

This is a three position switch, labelled FULL ON / AUTO / CLEAN. This switch along with the Iqan system, controls the pitch of the engine cooling fan.

Use buttons (3B), (3C), (3D) or (3E) to control each stabilizer separately.

Also see SETTING THE MACHINE in THIS SECTION. 2.15

Controls and Operation

Tigercat 234B Loader

AUTOMATIC POSITION - AUTOMATIC is the normal operating position for the fan control switch. When the switch is in the AUTOMATIC position, the fan will operate completely in an automatic mode. The computer control system will automatically control the fan pitch to minimize system energy losses and improve performance based on the temperature of the charge air, engine coolant and hydraulic oil. The computer system automatically adjusts fan air flow to the minimum required level to maintain optimal operating conditions.

Automatic control of fan air flow to match your operating conditions can lower fuel consumption and reduce operating costs. In high temperature operating conditions the fan air flow is increased to improve cooling ability and efficient operation of the cooling assembly and air conditioning systems. In low temperature operating conditions fan air flow is reduced, as less cooling is required for efficient operation of the cooling assembly.

CAUTION Before placing the fan switch in the CLEAN position make sure that there are no personnel near the REAR of the machine in the area where the fan will expel debris.

CLEAN - DOWN POSITION - Momentarily pressing the switch to the CLEAN position will manually start the automatic clean cycle, reversing the flow of air (there is no need to hold the switch down). The pitch of the fan blades is changed and the direction of airflow through the engine enclosure is reversed. The change in airflow will blow debris from the radiator and reduce the risk of overheating and poor engine performance caused by a clogged radiator. When the CLEAN cycle is complete the fan automatically returns to normal air flow direction.

The auto clean cycle is adjustable through the computer control system menu Refer to COMPUTER ~ MAIN MENU - AUTO CLEAN FREQUENCY and AUTO CLEAN DURATION in THIS SECTION.

Note that when the switch is in the AUTOMATIC position and the fan air flow has stopped due to low charge air, engine coolant and hydraulic oil temperatures, turning ON the A/C will cause the computer system to immediately place the fan blades at a pitch to provide 30% air flow. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

It is also important to manually clean debris from the machine on a regular basis to maintain low machine operating temperatures.

Refer to CLEANING A/C CONDENSER AND COOLING ASSEMBLY in THIS SECTION.

In addition and if enabled, when this switch is in the AUTOMATIC position, the system will automatically run an auto clean cycle as per the frequency setting.

The auto clean cycle is adjustable through the computer control system menu Refer to COMPUTER ~ MAIN MENU - AUTO CLEAN FREQUENCY in THIS SECTION. FULL ON (OVERRIDE) UP POSITION When the switch is in the FULL ON position, the computer control system is overridden and the fan will run at FULL air flow (blades pitched to 100%), for cooling regardless of charge air, engine coolant or hydraulic oil temperatures. Normally the fan control switch is placed in the AUTOMATIC position for optimal cooling. The FULL ON position is intended for use in the event of a temporary failure of the control system.

PROBLEMS AND CORRECTIVE ACTION

ARMREST ADJUSTMENT

Rides Too Stiff/Seat Tends To Push Or Throw Operator Forward

Each armrest has 3 adjustments to place it in the required position. Loosen adjustment locking wing-bolts to reposition armrest height, angle and fore/aft position. The wing-bolt handles can be pulled outwards and repositioned to work like a ratchet. Loosen adjustment bolts on the underside of the armrest to adjust the width position.

The ride control knob has over tensioned the seat spring. This typically happens because the operator is trying to use the ride control knob to adjust the ride height rather than using height adjustment lever to raise the seat. Refer to height adjustment.

Rides Too Soft Or Bottoms Out And Pinches Operator The ride control knob has under tensioned the seat spring Insufficient tension exaggerates the knee-action movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of spring tension instead of using the Height Adjustment lever. Refer to height adjustment.

FORE/AFT ADJUSTMENT BOLT

234-103

Seat Too High/Seat Too Low

VIEW FROM LEFT OF SEAT

Loosen the fore/aft adjustment bolt to allow the armrest to slide forward or back.

There are several things which can cause improper seat height. Refer to the HEIGHT ADJUSTMENT and adjust seat to the desired position. If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

UP/DOWN/ANGLE ADJUSTMENT BOLT

Operator’s legs falling asleep The seat is adjusted too high, and the ride control adjustment knob has under tensioned the seat spring, resulting in the operator sitting in a 'bucket'. Refer to height adjustment and RIDE ADJUSTMENT.

Controls and Operation

COLD WEATHER STARTING

NOTICE

During cold weather, the engine idle speed is controlled by the computer to limit maximum engine speed until the hydraulic system temperature has warmed to a specific temperature based on the oil grade selected.

TEMPERATURE

21°C (70°F)

4.5°C (40°F) 1400 RPM

1850 RPM

• DO NOT IDLE THIS ENGINE FOR MORE THAN 9 HOURS. • DAMAGE TO EMISSION CONTROL SYSTEM WILL RESULT.

ENGINE SPEED

As the machine hydraulic system temperature rises the engine idle speed can be increased. The length of time it takes is dependent on ambient temperature and oil grade selected.

63281BENG R0

Example: ISO 46 oil grade at 21°C (70°F) or above, engine speed can be increased to maximum idle speed of 1850 rpm.

IMPORTANT! Engine should not idle longer than 9 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 aftertreatment 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 9 hour long idle.

NOTE: The idle down function will not work until the engine idle speed can be increased to full rpm.

DEF fluid is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) aftertreatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

The DEF tank is located in the compartment beside the boom saddle. The DEF tank fill cap can be accessed by lifting the hinged lid on top of the compartment. The DEF tank fill point is equipped with a filter to prevent contaminants from entering the tank.

DEF tank capacity is 43 L (11.4 gal US). 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).

DEF is used by the SCR after-treatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust of this vehicle.

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

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.

When DEF levels are low information messages 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 in THIS SECTION.

When a problem with DEF quality is detected information messages 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 in THIS SECTION.

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 aftertreatment 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.

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 aftertreatment system.

IMPORTANT !

Engine should not idle longer than 9 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 aftertreatment 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 9 hour long idle.

WARNING

DANGER

When the stabilizers are on the ground, Hydraulic oil in the cylinders can be under very high pressure. Never remove the check valve or the counterbalance cartridges when the stabilizers are on the ground.

Moving stabilizers can cause serious injury or death. Ensure area is clear of all personnel prior to operating stabilizers.

The loader must be located and firmly set in place prior to operating.

LOWER FRAME

VERTICAL CENTERLINE COUNTERBALANCE VALVE

Refer to the following steps to ensure safe operation. (a) Locate the loader on firm level ground only. (b) Lower the stabilizers to set them firmly on stable ground. If the loader is mounted to a trailer, the stabilizers should be used to raise the rear of the trailer off the ground. Ensure loader is sufficiently stable to perform all log loading operations.

STABILIZER UP IN VERTICAL POSITION

(c) Stabilizers should be lowered so that the weight is just taken off the trailer or carrier tires and the loader is level. The machine should not be operated with the stabilizer cylinders fully extended; they should have at least 1/2" of unused stroke so that the counterbalance valves may relieve pressure build up caused by an increase in temperature.

STOPPING THE ENGINE

Note that whenever the engine is stopped all DEF solution 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 for more information.

IMPORTANT! Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool.

Note also that this machine is equipped with an After Run/ Accessory Relay which delays by 90 seconds the power disconnect to engine related fuses and relays (ECM /ATS relay, NOx Sensor relay, NOx Sensor fuse, ECM Power fuse, DCU fuse).

Always follow this engine shut down procedure. The important benefits are: •

Extended life of engine, cooling and exhaust systems.

•

Reduced risk of post shutdown fires.

•

Interior of machine cools significantly reducing risk of touching hot surfaces.

IMPORTANT! Only use the master disconnect to shut off a running machine in an emergency. A fault code will be logged by the ECM on the engine for improper shut down and power down.

1. Ensuring grapple and booms are fully supported by lowering grapple onto the trailer, carrier or stable ground.

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

3. Ensure all controls are in neutral positions and that all accessories and functions are turned off.

4. Do not race engine before shut-off 5. Stop engine by turning Key switch to the OFF position.

6. Ensure grapple and booms are fully supported and that all functions are turned off. Remove key from switch, lock up cab and turn battery disconnect switch to OFF prior to leaving the machine.

7. Perform daily maintenance at the end of the shift (greasing, clean engine compartment etc.). This allows the machine time to cool down while under the watchful eye of the operator.

CARE OF MACHINE

CARE OF POLYCARBONATE WINDOWS IN CAB

1. Ensure that all fluid levels are always at the proper level. Refer to the LUBRICATION AND MAINTENANCE SCHEDULE provided in SECTION 3 of THIS MANUAL.

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.

2. Follow proper procedure for cleaning windows described in this section.

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.

3. Lubricate all necessary points as per the maintenance schedule provided.

4. Never apply a load to a cold engine.

5. Close and secure all doors and access panel prior to operating machine.

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

6. Clean machine including all platforms, inside engine enclosure and around radiator of all dirt and debris on a regular basis.

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.

7. Keep all steps, ladders and platforms clear of oil and other material or debris that can cause an unsafe condition.

8. Ensure grapple head or boom is resting securely before shutting down the machine or servicing.

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

Controls and Operation

Tigercat 234B Loader

INSPECTION AND MAINTENANCE

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.

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.

•

•

•

•

Other chemicals however can seriously weaken the polycarbonate.

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.

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.

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

•

Acquer 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.

Exposing polycarbonate to repeated steam cleaning 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

CAUTIONS

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.

•

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

•

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.

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

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 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.

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: • • •

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

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

OIL SAMPLE COLLECTION PROCEDURES 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.

FILTER RESTRICTION INDICATOR

OIL SAMPLING CONNECTOR

HYDRAULIC OIL RETURN MANIFOLD 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.

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.

• To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of 90 – 120 mL (3 or 4 oz) of oil into a separate container and discard this oil using approved recycling methods.

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.

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

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

Gearbox Samples: • These samples can be taken during the oil change process.

• 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.

• 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.

• 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.

• 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.

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 oil and containers. 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 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 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 Top up diesel fuel at each shift to reduce contamination by condensation. þ Clean up oil spills in engine enclosure immediately. þ Before welding on machine be sure the negative battery terminal is disconnected and all multi-pin connectors from the engine are unplugged. 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 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. *OIL LOST FROM LEAKAGE

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.

IMPORTANT! 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 repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

SLIDING WINDOW HANDLE

1. Pine needles and bark 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.

Open the right side window by lifting the latch handle and slide the window open.

INSIDE CAB

2. Pay close attention to wiring and hose routing 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.

234T-046 234T-047

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

R.H. WINDOW SCREEN

On machines equipped with window screens, there are two hand knobs (1), one on the inside and one on the outside that can be removed to open the window screen. Only one hand knob has to be removed to open the window screen as follows:

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

From inside the cab: Open the cab window and turn the inside hand knob (1) counterclockwise to remove the hand knob and open the window screen. Push the window screen out to open it. Exit the cab if you can safely do so.

HYDRAULIC TANK VACUUM SYSTEM

The purpose of the vacuum pump system is to hold the hydraulic oil in the tank when servicing pumps and other hydraulic components, minimizing oil spill. When activated, a solenoid valve closes off the hydraulic tank breather air supply. The pump removes tank air to create a vacuum, which then holds the oil in the reservoir. This system eliminates the need to drain the hydraulic tank beforehand.

NOTE: When the ignition key is in the RUN position, the vacuum pump system will not start.

Alternatively if the vacuum pump is on, the engine cannot be started. The vacuum pump also will not start if the battery disconnect switch is in the OFF position.

Do not use the vacuum pump when changing hydraulic filters, instead use the Air Vent Valve to release pressure from the hydraulic tank. Using the vacuum pump system while changing filters creates the risk of introducing much more air into the hydraulic system.

It is OK to use the vacuum system when changing the case drain strainers.

SWITCH IN ENGINE COMPARTMENT This switch is "unswitched" and will function even with the battery disconnect switch in the off position. With the ignition key switch in the OFF position and the key removed, push the right hand side of the switch to put it in the ON position to activate the vacuum pump.

Activating the pump will create a vacuum condition (9 in.Hg) in the hydraulic tank. The vacuum pump will automatically start and stop as necessary to maintain the tank vacuum. The vacuum switch will also lock out the start solenoid to prevent the engine from being started.

Relieve the vacuum in the tank by placing the vacuum switch in the OFF position.

NOTE: The engine will not start until the tank vacuum has been relieved.

IMPORTANT! It is recommended that the start key be removed while servicing the hydraulic system.

Do not attempt to START the machine or turn key to the RUN position.

Do not leave machine unattended or overnight with vacuum pump on.

HYDRAULIC HAND FILL PUMP

The hydraulic hand fill pump is used to add oil to the hydraulic reservoir. It is located inside the engine compartment near the front left corner and is made accessible by removing the front access panel.

Adding Oil Prior to adding oil to the reservoir, determine and repair the source of the oil loss. Remove hose clamp from end of suction hose, remove hose from stored position, thoroughly clean outside surface of suction hose and insert end into supply drum. Open the oil fill shut off valve (ball valve located on top of the hand pump). Operate the pump by moving the handle back and forth at medium speed and a steady motion. The oil passes through the filters on the return lines of the hydraulic system. When the sight gauge reads between LOW and HIGH cease pumping and return handle to upright position. Close the oil fill shut off valve.

HYDRAULIC RETURN FILTERS

The majority of return oil entering the hydraulic tank passes through 4 spin-on hydraulic oil filters.

One of the filters is a water absorbing filter (color blue) which is in place to assist with the removal of unwanted moisture from the hydraulic oil (the filters are rated 10 micron absolute).

Each filter head has a bypass valve with a 1.7 bar (25 psi) cracking pressure so that oil can bypass the filters if they become restricted.Before this valve is activated, a 1.4 bar (20 psi) filter restriction pressure switch installed in the return manifold, will send a signal to the computer control system when an oil flow in excess of 1.4 bar (20 psi) is encountered at the return filters. This pressure switch closes and the hydraulic oil filter bypass icon displays RED on the MD3 computer and the master alarm will sound.

NOTE: Turning on the hydraulic tank vacuum pump will assist the filling procedure.

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 manual.

Tier III and IV engines typically use filters with a very fine micron rating. 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.

Loosen the plug on the top of the remote fuel filter/water separator. Pump the hand primer until fuel begins to seep out around the loosened plug, continue to pump until no air bubbles are visible (approximately 30 pumps).

Tighten the plug. Pump the hand primer 30 more times.

9. Start the engine and check for leaks. Refer to STARTING ENGINE in SECTION 2 of the OPERATOR'S MANUAL.

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

WARNING

Drain fuel filter into a container and dispose of all fluids properly.

To prolong the operating life of the fuel filter, ensure that the fuel supply storage tank is clean and free of water and that the fuel is pre-filtered prior to adding it to the machine.

The air cleaner on this machine uses 2 filter elements, a primary element and a safety element.

To ensure maximum engine protection, it is important that the elements be serviced correctly and at proper servicing intervals.

234B-0082

AIR FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure beside the air cleaner. The indicator is remote mounted and is connected to the outlet side of the air filter with a 1/4" diameter hose. Replace the primary air filter when the restriction indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After replacing the filter, reset the indicator by pressing the reset button.

NOTE: Replace the safety element every third primary filter change.

AIR CLEANER UNLOADER VALVE This rubber valve on the tube of the air cleaner housing should be checked at the beginning of every shift. (8 hours) If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective. The unloader 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 should be soft and flexible. If it is plugged, then check the filter elements, they may need replacing. Re-attach the valve to the tube.

The valve should suck closed at about 1/3 of full throttle.

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

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.

OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that is dirty is actually 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 the engine manufacturer’s guidelines, should be replaced.

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single factor contributing to engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner element has been removed for replacement. The safety element reduces the risk, however it must also be replaced at every third primary element change.

726D-006PLT

AIR FILTER ELEMENTS

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Release the cover latches gently to reduce the amount of dust dislodged.

2. Avoid dislodging dust from filter element(s) by gently pulling the element out of the housing.

3. Check your old filter sealing surfaces, This will help 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.

4. Always clean the inside of the housing.

5. Always clean the sealing surface before inserting a new filter element.

6. Inspect the new filter for damage.

7. Insert the new filter properly. Apply pressure to the filter frame not the pleated filter surface.

8. Check connections hoses and tubes for an air tight fit. Ensure that all clamps, bolts and connections are tight. Check rubber elbows for splits or wear points. Leaks in these locations send dust directly to the engine.

NOTE: Refer to diesel engine manufacturer's operation and maintenance manual for more details and additional required maintenance of the Air Cleaner or replacement of the air filter elements.

AIR CLEANER PRECLEANER

AIR PRECLEANER 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. The air precleaner should be checked every 8 hours to make sure that foreign materials have not plugged the intake area or the discharge louver area. Clean as required.

IMPORTANT! The air precleaner must be checked every 8 hours and cleaned as required.

If the inlet/precleaner is plugged causing a restriction to airflow, reduced engine performance and increased fuel consumption may result.

If a plugged inlet/precleaner is left too long, excessive air intake restriction may damage the rubber air intake tube. A damaged air intake tube will lead to ingestion of dirt into the engine which may result in engine failure.

480-017

PRECLEANER OPERATION

OPERATION: 1. Air enters the precleaner.

2. Specially designed vanes move dirty air toward the impeller.

3. The spinning impeller spins the air creating centrifugal force to separate contaminants from the clean air.

4. Contaminants are blown out the discharge louver.

5. Clean air enters the intake to the air cleaner.

Note that the air filter restriction indicator may not function properly if the air intake tube is damaged.

Engine failures due to improper maintenance are not covered by Tigercat or Engine Manufacturer’s Warranty and any such claim will be denied.

IMPORTANT! For peak engine performance and maximum fuel economy, please ensure that the air precleaner is regularly checked and cleaned as required. All intake air tubes and clamps should be thoroughly inspected on a regular basis and any damaged or missing components should be replaced immediately.

Tigercat 234B Loader DIESEL OXIDATION CATALYST / SELECTIVE CATALYTIC REDUCTION AFTERTREATMENT SYSTEM (DENOX 2.2 SYSTEM - TIER 4 FINAL) The engine on this machine is equipped with a combination Diesel Oxidation Catalyst (DOC) and high efficiency Selective Catalytic Reduction (SCR) aftertreatment system to limit the nitrogen oxide exhaust gas values (NOX) to meet Tier 4 Final emission standard requirements with low fuel consumption. This process is electronically controlled by the DENOX 2.2 system.

The diesel oxdation catalyst (DOC) uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2).

Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR aftertreatment system as a whole.

The high efficiency SCR process is based on a 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). In addtion the high efficiency catalytic converter includes a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

DOC/SCR AFTERTREATMENT SYSTEM

The DOC/SCR aftertreatment system is electronically managed by the DeNOX 2.2 system incorporated into the engine control unit (ECU).

The ECU calculates and adjusts the flow rate of the DEF solution into the system based on current engine speed, torque delivered, exhaust temperature, amount of nitrogen oxides and ammonia present.

The exhaust passes through the diesel DOC which uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). It also converts nitrogen oxide (NO) into nitrogen dioxide (NO2) which enhances the performance of the SCR catalyst.

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

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).

Finally the high efficiency catalytic converter incorporates a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

IMPORTANT !

Engine should not idle longer than 9 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 DOC/SCR aftertreatment 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.

The first phase of the SCR 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.

250D-064

OUTLET NOX SENSOR ECU

The outlet NOX sensor is mounted at the outlet of the catalytic converter and the outlet NOX sensor ECU is mounted on the same bracket as the NH3 sensor ECU next to the radiator of the left side of the engine compartment.

The NOX sensors detect and send information about the dosing of DEF solution and the efficiency of the catalytic converter to the Denox 2.2 control system. This information is used to calculate the amount of DEF fluid to be injected into the system and to monitor DOC/SCR aftertreatment system operation.

Each 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.

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.

DIESEL EXHAUST FLUID (DEF) HANDLING

AVOID DEF QUALITY PROBLEMS WITH PROPER HANDLING PRACTICES

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.

Most DEF quality problems can be avoided entirely with a little care and proper handling of DEF fluid.

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 aftertreatment system components. Refer also to COMPUTER – MESSAGES AND WARNINGS in SECTION 2 of the OPERATOR'S MANUAL or SECTION 6 of the SERVICE MANUAL.

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 aftertreatment 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.

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. NEVER fill the DEF tank with any other fluid.

DEF fluid is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) aftertreatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

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.

CHECKING AIR CONDITIONING SYSTEM

CAUTION

IMPORTANT! It is recommended that during cold weather when the A/C system is not in use, that it be run for a period of 5 minutes every two weeks to circulate oil to all components of the system.

R134a REFRIGERANT

PAG OIL

Without cab riser: 1.5 kg (54 oz) 74 mL (2.5 oz) With 29" cab riser: 1.8 kg 64 oz) 89 mL (3 oz) With 62" cab riser: 1.9 kg (68 oz) 104 mL (3.5 oz) Any service work must be performed by authorized A/C technicians. The system should be charged with R134a refrigerant. At least the minimum amount of PAG (polyalkylene glycol) oil, shown above, should be present in the system and must be used on O-rings and fittings during assembly.

• If using compressed air for cleaning, use 2 bar (30 psi) or less.

• Always use personal protective equipment to guard against flying debris.

Use the following checklist to maintain system between service intervals. The compressor and charge valves are located on the left side of the engine and accessible through the engine compartment door. The receiver dryer is located in the lower engine compartment beside the front left engine mount and accessible from either underneath the engine compartment or through the engine compartment door.

Perform the following checks on system:

Tigercat 234B Loader CLEANING COOLER PACKAGE

The A/C condenser core is located on the right side of the machine and is one of the cores in a stack of four that make up the cooler package.

The cooling fan is mounted on the front of the engine. The fan draws air from the right side of the machine through the door screen and the cooler package blowing it out of the opposite side of the machine.

Lubrication and Maintenance PROCEDURE:

CHARGE AIR COOLER T250D-029

Remove the 3 capscrews and washers and swing open the screen door on the right side of the engine compartment.

CAUTION

OIL COOLER

234E-288

CHECK CHARGE AIR COOLER, RADIATOR, A/C CONDENSER AND OIL COOLER The cooler package should be manually checked every 8 hours (every shift) or more often where conditions cause accumulation of twigs, leaves, pine needles and dust. All of the engine enclosure doors should also be checked.

• If using compressed air for cleaning, use 2 bar (30 psi) or less.

• Always use personal protective equipment to guard against flying debris.

This cooling assembly must be checked daily and may require thorough cleaning on a regular basis depending on operating conditions. Compressed air or water may be used for cleaning. Use personal protective equipment to guard against flying debris.

If an oil leak occurs in this area it should be thoroughly power-washed with a mild soap to ensure that all of the oil is removed. The presence of oil causes dust and dirt to cling to surfaces which will impair the reversible fan's ability to remove dust and dirt particles.

Care must be taken when cleaning this assembly, as the components can be damaged by careless handling and cleaning.

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.
