Tigercat 1075C/1085C Forwarder

THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING PROTECTIVE STRUCTURE STANDARDS: ISO 8082:2003 (Roll Over) Maximum Machine Mass 29 869 Kg/ 65,850 Lb ISO 8083:2006 (Falling Object) ISO 8084:1993 (Operator) * MODIFICATIONS AND REPAIRS: The integrity of the Roll Over, Falling Object, Operator protection 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 Roll Over, Falling Object and Operator protection structure will become void if any such modifications 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 Roll Over, Falling Object and Operator protection standards so that they will withstand force and absorb energy during a roll over, when resisting the impact of a falling object and minimize the possibility of operator injury from penetrating objects.

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.

Use only the recommended adhesive for fastening windows. Operator protection standard requirements may not be met if an adhesive other than the one recommended is used. Replace windows only with factory approved parts.

The mounting and the frame or chassis to which the cab is attached is considered an integral part of the Roll Over, Falling Object, Operator protection structure 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.

Tigercat 1075C/1085C Forwarder FLUID INJECTION INJURY

Safety 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.

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.

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.

•

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.

Safety

Tigercat 1075C/1085C Forwarder

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.

LIGHTNING SAFETY AWARENESS

Tigercat 1075C/1085C Forwarder LIGHTNING SAFETY 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.

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.

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.

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.

•

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.

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.

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.

1.20

Tigercat 1075C/1085C Forwarder

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:

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

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.

•

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:

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 fibreglass or plastic body shells or in convertible top vehicles. None of these are safe, as they do not offer skin effect lightning protection.

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.

1.21

•

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.

Safety

Tigercat 1075C/1085C Forwarder 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.

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

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

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.

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

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

6. Avoid entering any small enclosures or shelters.

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.

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.

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.

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

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. Call your local emergency response telephone number immediately.

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.

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

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

11. Do not use the telephone except for emergencies.

1.22

Tigercat 1075C/1085C Forwarder

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.

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 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.

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. 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 smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

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 15 METERS (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.

1.23

Safety 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.

Tigercat 1075C/1085C Forwarder 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.

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

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

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.

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.

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.

suppression system** on your machine.

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

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.

Pull the pin at the top of the extinguisher that keeps the handle from being pressed.

Break the plastic seal as the pin is pulled.

WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED •

1. Ensure that the cause of the fire is determined and all appropriate repairs are completed.

Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. In order to put out the fire, you must extinguish the fuel, not the flames. Hose nozzles are often clipped to the extinguisher body.

Release the hose before taking aim.

Squeeze the handle to release the pressurized extinguishing agent. The handle can be released at any time to stop the discharge.

Sweep from side to side at the base of the fire until the fire is completely out or the fire extinguisher is empty

Before returning the machine to work.

2. Ensure that the fire detection system*

or the fire suppression system** is properly serviced and in working order (if applicable).

3. Ensure that all extinguishers used in fighting the fire are replaced or recharged.

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

Only if you can safely do so, open the access panels to the machine in the area of the fire.

Failing all attempts to access the machine compartment, discharge the extinguisher through the mesh or any available openings on the machine.

Ensure that the machine and all components have cooled down sufficiently after a fire so that re-ignition does not occur.

Remain with the machine until help arrives.

1.26

Tigercat 1075C/1085C Forwarder 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.

6. PARKING BRAKE SWITCH P

FULL ON POSITION - When the switch is in the FULL ON position, the fan control system is overridden and the fan will run at FULL speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling. The FULL ON position is intended for use in the event of a temporary failure of the fan control.

This is a two position switch which operates the parking brake function.

Press the top of this switch (ON) to ENGAGE the parking brake. The parking brake icon P on the main menu of the computer display will be illuminated when the parking brake is engaged.

The parking brake switch is also used to break the pilot. Placing the parking brake switch in the ON position will break the pilot.

CLEAN POSITION - When the switch is held in the CLEAN position the direction of rotation is reversed. Reverse rotation is used to clean the charge air cooler, radiator, oil cooler, A/C condenser and air intake hood screens. By “reversing” the flow of the fan, air flow is propelled in the opposite direction, thereby forcing dust and debris off of the coolers.

Press the bottom of this switch (OFF) to DISENGAGE the parking brake. The parking brake icon will remain illuminated until the parking brake pressure switch is disengaged.

To reset the pilot the parking brake switch must be in the OFF position and the cab doors must be closed. Refer to PILOT RESET SWITCH in THIS SECTION for more information.

CLEAN is a manual operation and the switch must be held in the CLEAN position to perform this operation. It is also best to have the engine at high idle when using the CLEAN operation.

NOTE ALSO: The drive interlock system prevents the machine from being driven and function controls from being operated while the parking brake is ENGAGED.

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

Refer to CLEANING A/C CONDENSER AND COOLER PACKAGE in THIS SECTION.

7. COOLING FAN SWITCH ( /AUTO/ )

8. EMERGENCY SHUT-OFF SWITCH

This is a three position switch, FULL ON/ AUTOMATIC/ CLEAN. This switch along with an electronic fan control, controls the operation of the hydraulic cooling fan.

AUTO POSITION - AUTO is the normal operating position for the fan control switch.

When the switch is in the AUTO position, the fan will operate completely in an automatic mode. It will speed up or slow down all based on the temperature of the charge air, engine coolant and/or the temperature of the hydraulic oil. The electronic control automatically adjusts fan speed to the minimum required level to maintain optimal operating conditions, and default to fan at full speed if an error in the controller exists.

When the emergency shut-off switch is pressed DOWN, it immediately turns OFF electrical power to all functions within the cab including the computer system which, in turn shuts down the engine and hydraulic systems.

To allow the power to return to the cab, turn clockwise to allow it to pop back up.

IMPORTANT! The emergency shut-off switch should only be used in emergencies. Error codes will accumulate in the engine computer when the emergency shut-off switch is used.

9. WARNING HORN SWITCH

When the switch is in the AUTO position and the fan runs at minimum speed due to low charge air, engine coolant or hydraulic oil temperatures, turning ON the A/C will cause the fan control to increase the cooling fan speed slightly. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

This is a two position momentary switch.

Press and hold this switch to sound the safety alert horn.

Always use this horn prior to starting the engine and to alert other personnel in the area of your presence.

GENERAL CRANE

The following crane functions can be adjusted to fine tune the operating speeds and start/ stop ramps. In addition band width limiting and dampen settings can be adjusted.

Crane Speed (%) Crane speed is a single adjustment that will reduce the maximum crane speeds of all the crane functions (except grapple open or close). The new speeds will be the maximum speed setting of each crane function multiplied by the percentage displayed.

Refer to JOYSTICK CONTROL OUTPUT ADJUSTMENT SETTINGS in THIS SECTION for more information about how start slope, stop slope, fine control, BWL and dampen settings affect function performance.

Crane Working Speed (rpm) The crane working speed adjustment is used to customize the crane working speed function speed setting according to operating conditions/operator preference.

Refer to COMPUTER – ADJUSTMENT MENUCRANE ADJUST – CRANE ADJUSTMENT SETTINGS REFERENCE CHART in THIS SECTION for range and default setting information.

Refer also to CRANE ON/OFF SWITCH and CRANE WORKING SPEED SWITCH in THIS SECTION.

Main Boom Stop Cushion +/(Tigercat Crane Only) This setting adjusts the performance of the main boom stop cushion function. This function uses the signal from the main boom proximity sensor to reduce main boom speed as the boom approaches the limit of cylinder stroke. A lower setting will result in a harder main boom stop impact. A higher setting will result in a softer main boom stop impact.

NOTE: Default computer settings require that the crane on/off switch be used in conjunction with the crane working speed switch. In this case the minimum engine rpm setting is available only when operating the crane.

Alternately settings can be adjusted to make this minimum engine rpm setting available for travelling operations in addition to crane operation. In this case the crane working speed switch works independently of the crane on/off switch. Refer to COMPUTER – ADJUSTMENT MENU-CRANE ADJUST– GENERAL CRANE – WORKING SPEED ACTIVE ALWAYS.

Stick Boom Stop Cushion +/(Tigercat Crane Only) This setting adjusts the performance of the stick boom stop cushion function. This function uses the signal from the stick boom proximity sensor to reduce stick boom speed as the boom approaches the limit of cylinder stroke. A lower setting will result in a harder stick boom stop impact. A higher setting will result in a softer stick boom stop impact.

Working Speed Active Always This setting toggles the operation of the crane working rpm switch from default to alternate settings.

SLEW (CRANE SWING) Slew adjustments are used to customize the crane swing functions +CW/-CCW.

If this setting is No (default setting) the crane working rpm switch works with default computer settings which require that the crane on/off switch be used in conjunction with the crane working speed switch. In this case the minimum engine rpm setting is available only when operating the crane and the operator’s seat is facing the crane.

MAIN BOOM Main boom adjustments are used to customize the main boom function +UP/-DOWN. STICK BOOM

If this setting is Yes (alternate setting) the crane working rpm switch works independently of the crane on/off switch making the minimum engine rpm setting available for travelling operations in addition to crane operation, regardless of seat position.

JOYSTICK CONTROL OUTPUT ADJUSTMENT SETTINGS (CURRENT OUT)

START/STOP SLOPE Current [mA] Max current

The following settings fine tune the operating speeds and start/stop ramps for the joystick controlled functions. In addition band width limiting and dampen settings can be adjusted.

A general description of each adjustment is given below as a guide to using these function adjustments to customize joystick operated machine functions according to operator preferences.

More information about specific adjustable functions is provided on the following pages which cover the machine adjust, crane adjust and drive adjust menus.

Minimum current settings control function start speed. Coils on hydraulic valves require a certain amount of current before they begin to operate the valve. The Min current value is the current that will be sent to the hydraulic valve coil when the joystick is moved a very small amount.

Fine Control changes the current output to joystick position curve from being a straight line to being a curved line. Lower numbers make the first 50% of joystick movement create more output. Higher numbers make the first 50% of joystick movement create less output.

The min current is adjusted to a value that causes the function to just begin to move.

MAXIMUM CURRENT Current [mA]

Tigercat 1075C/1085C Forwarder

Controls and operation

BWL (BAND WIDTH LIMITING) Band width limiting settings decrease the frequency bandwidth of the (joystick) output signal whenever the change of the output signal is smaller than BWL window. The bandwidth limit will decrease linearly with smaller changes. When the change of the signal is zero, the bandwidth will also be zero. When the signal change is larger than the window, no bandwidth limitation will be used.

This function is particularly good to use for signals that are “nervous” but where a normal filter would decrease the overall dynamics of the signal, such as joystick control for a crane function.

An example is operating on uneven and rough terrain where the machine movement may make the operator’s hands shake and unintentionally stroke the joysticks causing a spike in output signal. The BWL filters clip off the high points in output signal, smoothing changes in joystick function movement.

Setting BWL to a low value (0% minimum setting) will result in less filtering. Setting BWL to a high value (50% maximum setting) will result in more filtering smoothing out the function operation.

DAMPEN Dampen settings control the amount of travel required on the joysticks to reach full function speed. The value of the dampen setting is the percent of full travel that the joystick needs to be moved, to reach full function speed.

Adjusting dampen settings to a low value, will result in very sensitive control, and reduces movement of hands, fingers and wrists – resulting in reduced operator fatigue.

Adjusting dampen settings to a high value, will utilize more of the complete joystick travel and will make the function control less sensitive (easier to operate) but, will require more hand movement.

For inexperienced operators, dampen settings should be set high. Once operators are comfortable with operating the function, the dampen settings can be brought down to a desired level, based on operator preference.

CARE OF THE MACHINE

CARE OF POLYCARBONATE WINDOWS IN CAB

1. Ensure that all fluid levels are always at the proper level. Use the preventative maintenance schedule 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. Apply grease to all lubrication points at required intervals.

4. Do not apply load to a cold engine.

5. Close and secure all doors and access covers.

6. Do not allow branches, twigs, leaves or pine needles to build up around hood screens, or engine air intake screens or anywhere else on the machine. Clean frequently but at least once daily.

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 CLEANING A/C CONDENSER AND COOLER PACKAGE in THIS SECTION. 7. Be sure that the crane is in the park position and the blade (if equipped) is resting on the ground before servicing or parking the machine.

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

IMPORTANT !

When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the exhaust tube. Water in the exhaust tube will damage sensors and SCR system components and affect the proper operation of the aftertreatment system and the engine.

IMPORTANT !

When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the air inlet. Water in the air inlet will damage the air intake system components and affect the proper operation the engine.

INSPECTION AND MAINTENANCE

RESISTANCE TO CHEMICALS

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

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.

•

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.

Other chemicals however can seriously weaken the polycarbonate.

•

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.

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

•

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.

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 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

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.

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

GRAFFITI REMOVAL

CLEANING COOLER PACKAGE

•

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.

The A/C condenser core, oil cooler, radiator and charge air cooler all make up the cooler package.

The hydraulically driven fan draws air from the front of the machine through the hood screen, the A/C condenser, the oil cooler, the engine radiator, and the charge air cooler blowing it out on either side of the engine.

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

The fan switch has a clean position for reversing the fan rotation. By reversing the fan rotation the air flow is propelled in the opposite direction forcing dust and debris off the cooler package and hood screen. See COOLING FAN SWITCH in this section for details of fan operation.

COOLER PACKAGE

FIRE PRECAUTIONS 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.

1075C-140

A/C CONDENSER AND COOLER PACKAGE

This cooling assembly must be checked daily for debris and may have to be thoroughly cleaned on a weekly or monthly basis, depending on operating conditions. Compressed air or water may be used for cleaning. If an oil leak has occurred 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 will cause dust and dirt to cling to surfaces reducing the fan’s ability to distribute air. Care must be taken when cleaning this assembly, as the components can be damaged by careless handling and cleaning.

The hood screen, A/C condenser core, oil cooler, engine radiator and charge air cooler should be manually checked every 8 hours (every shift) for accumulation of twigs, leaves, pine needles and dust.

TIGERCAT OIL ANALYSIS 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 analyse 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, front and rear axle differentials, planetaries, bogie housings, transmission, etc.

Tigercat Oil Analysis Kits are available from your Tigercat dealer parts department. If required, arrangements can also be made with your Tigercat dealer to supply and perform all of the required followup oil samples.

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, main pump, differentials, planetaries, bogies, transmission, 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.

3.4

Tigercat 1075C/1085C Forwarder

Lubrication and Maintenance

TIGERCAT OIL ANALYSIS PROGRAM 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.

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.

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.

•

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, Differentials, Planetaries and Bogie Axle Samples: • These samples can be taken during the oil change process.

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.

3.5

•

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

•

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 When welding, secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings

CAUTION All handles, steps and platforms must be kept free of grease, oil, fuel, mud, snow and ice.

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires

Clean around fill caps before checking or adding fluids.

Always have a fire extinguisher at hand and know how to use it

Release hydraulic pressure and clean around hydraulic fittings before breaking connection.

Plug or cap immediately.

For safety; when leaving the cab or leaving machine unattended or during service, always place the crane in the park position or other SECURE position, and lower the blade (if equipped). Turn the ignition switch off. Turn the battery disconnect switch off.

Clean up ALL spills immediately.

Always use clean oil and containers.

Drain dirty oil while still warm.

Do not exceed recommended fluid levels.

For safety, always block or support the crane and blade (if equipped) when working under them.

Service all hydraulic filters, and return strainer after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system.

Top up diesel fuel at end of each shift to reduce contamination by condensation.

CHECK EMERGENCY EXITS MONTHLY

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.

Alternate exit route is provided: the window on the right side of the cab. This exit is only to be used if the cab door cannot be opened.

It is therefore essential that this emergency exit be checked at least once per month to ensure it is fully operational.

Refer to EMERGENCY EXITS in SECTION 2 of the OPERATOR'S MANUAL and CAB EXITS in SECTION 1 of THIS MANUAL.

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.

Before welding on machine be sure master switch is disconnected and disconnect multi pin connectors on engine CPU and engine wiring harness.

GENERAL 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.

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.

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 turn off the engine before discharging the fire suppression system.

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

Tigercat 1075C/1085C Forwarder FILTERS - REMOVE AND REPLACE IMPORTANT !

Failure to service and replace filters at the proper intervals specified in the manufacturer's manuals, could cause damage to the machine and result in the product warranty becoming NULL and VOID. Check Tigercat parts catalog for replacement filters.

PRIMARY FUEL FILTER AND SECONDARY FUEL FILTER/WATER SEPARATOR This machine is equipped with two fuel filters. The primary fuel filter is on the engine. The secondary fuel filter/water separator is a combination unit, with a replaceable fuel filter with drain valve and a reusable water in fuel sensor. For service and replacement intervals see SERVICE AND LUBRICATION POINTS in THIS SECTION.

Lubrication and Maintenance 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. The engine fuel injection system requires extremely clean fuel. To accomplish this, the engines typically use filters with a finer micron rating.

If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual. It is also recommended that the fuel/water separator bowl be drained daily.

Operating the machine with a clogged fuel filter will result in low engine power and severe fuel injection system damage.

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.

HAND PRIMER

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.

SECONDARY FUEL FILTER/ WATER SEPARATOR

WARNING To lower the risk of causing accidental fires, DO NOT leave fuel or oil soaked rags laying around.

PRIMARY FUEL FILTER

FUEL WATER SEPARATOR Changing the primary fuel filter: 1075C-066

WARNING

Refer to the appropriate ENGINE MANUFACTURER'S OPERATION and MAINTENANCE MANUAL for correct procedures, time intervals and filter specifications, when servicing the engine oil and fuel filters. Read and understand the SAFETY section in each of these manuals.

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

WARNING The fuel pump high-pressure fuel lines and fuel rail contain very high pressure fuel.

Never loosen any fittings while the engine is running. Personal injury and property damage can result.

If a plugged inlet 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.

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 inlet 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.

IMPORTANT !

When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the air inlet. Water in the air inlet will damage air intake system components and affect the proper operation the engine.

The air cleaner on this machine uses two filter elements, a primary element and a safety element accessible from the left side of the engine compartment.

A filter restriction indicator is connected to the outlet side of the air filter. Replace the primary air filter when the indicator shows RED. This indicator provides a continuous reading whether the engine is running or is turned off. After replacing the filter, reset the indicator by pressing the reset button.

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

A filter restriction indicator is mounted to the output side of the filter, this should show green when the engine is running under load.

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

Service is required if the indicator shows red. This machine is equipped with a switch used to send a signal to the computer control system in the event of an air intake filter restriction.

When a signal is received from the restriction indicator switch on the engine air cleaner a message will be displayed. Refer to COMPUTER – MESSAGES - ALERT – ENGINE AIR INTAKE FILTER RESTRICTED in SECTION 2 of the OPERATOR'S MANUAL.

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 valve should suck closed at 1/3 throttle.

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 should be soft and flexible. If it is 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.

INTAKE TUBING AND JOINTS

OUTLET TUBE

Check all air intake system components, rubber elbows, connector hoses, tubes and clamps for damage, hardening, wear, cracks, leaks, loose clamps or loose hanger bracket hardware and repair or replace immediately.

PRIMARY 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.

SAFETY ELEMENT

In addition to the SCHEDULED MAINTENANCE, the following instructions should also be noted.

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 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 engine manufacturer’s guidelines, should a filter be replaced.

NOTE: This does not apply to oil filters.

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single reason for engine damage due to dust.

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

AIRCLEANER

AIR FILTER ELEMENTS

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Thoroughly clean the air cleaner housing and surrounding area before opening air cleaner.

2. Release the cover latch gently to reduce the amount of dust dislodged.

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

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

5. Always clean the inside of the outlet tube and filter housing.

6. Check your old filter, It can 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.

7. Inspect the new filter for damage.

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

9. Check connections and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Check rubber elbows for splits or wear points. Leaks here send dust directly to the engine.

Tigercat 1075C/1085C Forwarder DIESEL OXIDATION CATALYST / SELECTIVE CATALYTIC REDUCTION AFTERTREATMENT SYSTEM (DENOX 2.2 SYSTEM - TIER 4 FINAL)

Lubrication and Maintenance The DOC/SCR aftertreatment system consists of the following components:

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 electronic 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.

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).

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 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).

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.

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum 3.30

ADJUSTING SNUBBER TENSION

Remove 3 bolts on the left side then loosen 3 bolts on the right side of the snubber enough to separate the end cap from the housing to remove the first half of the shim.

The snubber should be adjusted such that the grapple swings freely past center and then stops.

Snubbers that are overtightened can reduce the effect of lubricating grease and cause premature clutch wear.

Loosely reinstall the 3 bolts on the left side of the snubber then remove the 3 bolts on the right side keeping the end cap separated from the housing enough to remove the other half of the shim.

PROCEDURE Tension is adjusted by removing shims from the snubber. Remove only the minimum number of shims required to achieve correct adjustment.

1. Park machine on level ground, install articulation lock bar, lower the blade (if equipped) and place grapple on the ground for service, stop engine, remove key, then switch battery disconnect off, and block wheels.

Reinstall bolts and tighten in a crisscross pattern.

3. Fill snubber with grease until grease comes out the exhaust port.

2. Remove one shim at a time to increase snubber friction. One split shim at a time can be removed from each snubber without completely removing the end caps.

Lubrication and Maintenance must be adjusted or replaced before they wear down to a minimum thickness of 2 mm beyond the bracket.

Check the vertical and horizontal play of the telescopic boom as part of scheduled maintenance every 250 hours. Wear of the boom guides will result in an increased amount of play horizontally and vertically when operating the telescopic boom.

Note that adjustment or replacement of the rear boom guides requires disassembly of the telescopic boom. For this reason it is recommended that rear boom guides be replaced whenever major maintenance is performed on the telescopic boom. If the rear boom guides are only slighltly worn they can be adjusted with shims under the boom guides. Do not add too many shims under the rear boom guides as this will push them too far out of the brackets holding them in place and may cause them to pop out of place while in use.

The boom guides at the front and rear of the telescopic boom wear during normal use and require adjustment. Cranes that are frequently overloaded or used in extreme conditions will wear faster. Lack of regular greasing will also result in faster wear.

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.
