Introduction

Tigercat 718E Feller Buncher

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

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

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

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

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

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

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

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

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

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.

FLUID INJECTION INJURY 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.

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

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

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

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

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

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

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

•

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

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

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

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

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

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

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

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

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.

Safety LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

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

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.

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

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.

•

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.

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.

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.

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.

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

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.

1.19

Safety

Tigercat 718E Feller Buncher WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER.

LIGHTNING SAFETY AWARENESS continued

If you can, get inside.

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

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

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.

2. If inside a building:

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

•

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:

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.

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.

1.20

•

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.

LIGHTNING SAFETY AWARENESS continued

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

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

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

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

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.

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

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.

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.

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

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

6. Avoid entering any small enclosures or shelters.

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

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

2. Call your local emergency response telephone number immediately.

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

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.

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.

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.

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

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

11. Do not use the telephone except for emergencies.

Tigercat 718E Feller Buncher 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.

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

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

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

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

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.

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

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

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

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

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

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

1.22

Tigercat 718E Feller Buncher

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

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

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

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

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.

Tigercat 718E Feller Buncher

DRY CHEMICAL CLEANUP PROCEDURES

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.

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.

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 noncorrosive and nonconductive such as CRC Contact Cleaner 2000.

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

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

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

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

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

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

THE DANGERS

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

• Soil particles are thrown from the ground.

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

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

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

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

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

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

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

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

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

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

FIGURE 6: ADDITIONAL OPENING IN THE HOUSING SKIRT.

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

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

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

COMMENTS AND INSTRUCTIONS

Recognizing the Dangers While it may appear that these illustrated danger areas can be visually recognized on the job by observing how far chips fly during a cut, that is only true for chips and other light weight materials.

Metal parts and wooden spears can be thrown to surprisingly greater distances. Even distant personnel on the ground, in other vehicles, or in buildings are at risk if the throw is in their direction.

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

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

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

Assessing the potential dangers on the job site The extent of danger from high speed disc saws on the logging operation has to be assessed on the job site, depending on how much other work activity is in the area and whether the operator can do his job of cutting and bunching with good control of throw patterns. Danger is greater if the saw is equipped with detachable, or fragile, or brittle teeth, or if the site contains stones or abandoned metal.

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

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

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

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

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

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

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

Figure 11 warns that blocks of wood can be tossed in any direction when improvising with a disc saw to trim over-size stumps. A long snout and a slow feed speed lessen danger during stump trimming.

A similar danger of throw may exist when clearing small brush with multiple pass cuts.

Comments and Instructions cont.

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

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

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

Comments and Instructions cont.

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

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

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

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

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

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

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

Do not over speed the blade rpm.

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

Do not neglect tooth fastening inspection, maintenance and replacement.

Do not neglect to repair worn or damaged saw housings.

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

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

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

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

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

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

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

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

Do not select and operate heads that throw rearward.

Do not select and operate heads with unnecessarily wide throw angles.

Do not neglect to read and follow all instructions provided by the saw and head manufacturers.

PROBLEMS AND CORRECTIVE ACTION

SEAT ADJUSTMENTS

RIDES TOO STIFF/SEAT TENDS TO PUSH OR THROW OPERATOR FORWARD The RIDE ADJUSTMENT KNOB has been tightened (turned counter-clockwise) too much.

This typically happens because the operator is trying to use additional RIDE ADJUSTMENT KNOB rather than the HEIGHT ADJUSTMENT LEVER to raise the seat. Operator is riding the seat in the low height position setting. Refer to HEIGHT ADJUSTMENT.

BACK ANGLE ADJUSTMENT

LUMBAR HORIZONTAL ADJUSTMENT (NOT SHOWN)

RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The seat RIDE ADJUSTMENT KNOB has not been tightened (turned counter-clockwise) enough. Insufficient ride adjustment 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 ride adjustment instead of using the HEIGHT ADJUSTMENT LEVER. Refer to HEIGHT ADJUSTMENT.

Consider the four gauge increments as 1/4, 1/2, 3/4 and 1. During cutting operations the indicator value will rise to 1 as the blade slows down due to cutting, and fall as the blade speeds up. A 3/4 value or higher indicates that the blade has not attained full speed from the previous cut or has jammed. Further cutting should be delayed until the indicator value falls below the 3/4 increment to prevent stalling the saw blade during the next cut. Between 1/4 and 3/4 the saw blade is at optimum cutting speed.

INSTRUMENT PANEL

HYDRAULIC PUMP COMP'T

NOTE: Wait for 30 seconds after turning key switch off before turning the battery disconnect switch off. The engine ECM requires time after the engine is turned off to record the engine data and log the information for the current operating session. If the battery disconnect is turned off too soon, the data will not be recorded and an error message will be displayed when the battery power is turned back on and the key switch is turned on.

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

IMPORTANT: Only use the battery disconnect switch 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.

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

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

SYSTEM OPERATION There are 3 thermostats mounted in the engine and hydraulic area which are wired to the warning light and buzzer. The thermostats are automatic heat detection devices and are set to “close” at 177°C (350°F). When a thermostat closes it sends an electrical signal to the warning light and buzzer indicating that a high temperature has been detected. The stop engine light and horn will also be activated.

IN CASE OF FIRE DETECTION ALARM: 1. Stop machine operation, park machine in a safe location and lower the attachment to the ground.

CARE OF POLYCARBONATE WINDOWS IN CAB

•

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

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

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

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

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

• • •

•

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

Windows with these defects must be replaced immediately.

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

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

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

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

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

Other chemicals however can seriously weaken the polycarbonate.

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

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

• Inspect all windows daily and immediately after any impacts.

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

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

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

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

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

2.44

Tigercat 718E Feller Buncher

Controls and Operation

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

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

•

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

•

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

•

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

•

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

•

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

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

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

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

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

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

•

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

3. Rinse the window thoroughly with lukewarm water.

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

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

Controls and Operation 5. To deactivate the parking brake it will be necessary to provide portable hydraulic pressure 17.2 bar (250 psi) at the parking brake supply (C3) on the pilot manifold.

TOWING INSTRUCTIONS A malfunction of the machine's equipment may make towing necessary.

Towing is only recommended over short distances. It is always better to make repairs at the point where the machine is parked whenever possible.

1. To facilitate towing, the transmission must be placed in NEUTRAL, this will disconnect the wheels from the hydraulic motor.

718E-004

On two speed transmissions shift the gear shift lever in the cab to NEUTRAL.

C3

Block the wheels. Remove parking brake supply hose from pilot manifold (C3) and connect to a portable hydraulic power source.

Plug port on pilot manifold. Pressurize circuit to 17.2 bar (250 psi) to disengage parking brake.

On single speed transmissions shift the lever on the transmission to NEUTRAL position.

2. Raise the felling attachment off the ground and install the boom cylinder lift lock. Turn off the engine.

6. Remove articulation lock bar.

3. Install articulation lock bar.

STEERING CYLINDERS

PILOT MANIFOLD

7. The machine will be towed from the rear, making use of the towing lug at rear of machine underneath the bumper.

STEERING CYLINDERS

Ensure a vehicle of equal power and size is used for towing.

When going downhill, be sure to use a holdback vehicle as the machine is now without any effective braking.

SM47

NORMAL HOSE CONNECTIONS

8. When towing is completed, install articulation lock bar and reconnect steering cylinder hoses in proper location, remove remote hydraulic power source and reconnect parking brake hose to C3 port on the pilot manifold.

HOSES ON ONE CYLINDER CROSS CONNECTED FOR TOWING

4. To allow the machine to steer while towing and prevent damage to the steering cylinders, cross hydraulic hoses on one of the steering cylinders. This will allow trapped oil to flow freely between the two steering cylinders, providing ease of turning with some dampening effect.

CAUTION Before towing, the transmission must always be placed in NEUTRAL. Never tow a machine in gear. The extremely high forces created will cause significant damage to the components of the hydrostatic drive system and the transmission.

Never tow the machine at over 3 kph (2 mph). This will cause significant damage to the transmission.

Never press the forward or reverse pedals while the transmission is in neutral. This will cause significant damage to the transmission.

Refer to NEW MACHINE MAINTENANCE in THIS SECTION. FOLLOW-UP SAMPLES All follow-up samples must be taken as indicated in the chart above and will be the responsibility of the machine owner.

Copies of all oil analysis results must be forwarded to the Tigercat Warranty Department for continued warranty coverage. If samples are taken using the Tigercat Oil Analysis Program, a copy of all results will automatically be sent to Tigercat.

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 Prepaid Sample Bottle and Sample Information Form. Preprinted 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: Hydraulic Circuits, Final Drives, Axles, Gearboxes, Engines, etc.

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

Contact your Tigercat Dealer Parts Department to order Kits.

3.4

Tigercat 718E Feller Buncher

Lubrication and Maintenance

TIGERCAT OIL SAMPLING 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.

OIL SAMPLING CONNECTOR

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.

BOOM, STEER, SAW RETURN FILTERS

720E-014

HYDRAULIC OIL RETURN FILTERS

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

•

To obtain a representative oil sample, the 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, Axles and Pump Drive Gearbox Samples: • These samples can be taken during the oil change process.

•

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

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

•

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

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.

•

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.

Before welding on machine be sure master switch is disconnected and disconnect multipin connectors on engine CPU and engine wiring harness. þ When welding secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings. þ Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires. þ Always have a fire extinguisher at hand. þ For safety, always lower boom assembly to the ground when leaving cab, leaving machine unattended or during service. þ For safety, when working under boom, always lower to ground, support properly or install lift boom cylinder locking device . (Refer to section 2 of this manual) ______________________________________

þ Clean around filler caps before checking or adding fluids. þ Release hydraulic pressures and clean around hydraulic fittings before breaking connection.

Plug or cap immediately. þ Clean up spills as soon as possible. þ Always use clean hydraulic oil and filters. þ Drain dirty oil while still warm. þ Do not exceed recommended fluid levels. þ Service all hydraulic filters after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system. þ Top up diesel fuel at end of each shift to reduce contamination by condensation. þ Clean up oil spills on walking surfaces and top of engine enclosure immediately. þ Inspect the EXHAUST SYSTEM DAILY for any signs of LEAKAGE. Check for worn, cracked, broken, or damaged pipes or muffler.

Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, DO NOT OPERATE the machine until the exhaust leak is repaired. þ During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

þ

CHECK EMERGENCY EXITS, MONTHLY: Two alternate exit routes are provided: right hand cab door and the skylight/emergency exit. These are only to be used if the left hand cab door cannot be opened.

It is therefore essential that these emergency exits be checked at least once per month to ensure they are fully operational.

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.

CHECK FIRE EXTINGUISHER, DAILY:

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

CHECK CHARGE GAUGE DAILY

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

2. Pay close attention to wiring and plumbing 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.

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

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

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

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

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

FILTERS - REMOVE AND REPLACE IMPORTANT:

WATER SEPARATOR

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 catalogue for replacement filters.

FUEL FILTER

FUEL FILTER/WATER SEPARATOR Two fuel filters are supplied with the engine.

Refer to the engine manufacturer's operation and maintenance manual for service information and replacement interval.

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.

724E-027

FUEL FILTER/WATER SEPARATOR

PRIMING THE FUEL SYSTEM

Tigercat generally does not recommend the prefilling of fuel filters due to the risk of damage to the fuel system caused by unfiltered fuel. Unfiltered fuel used to prefill filters enters directly into the fuel system. Contaminants in unfiltered fuel can cause significant and costly damage to the engine. The cleanliness of fuel cannot be guaranteed unless it is always prefiltered before use.

Whenever the fuel system has been drained, disconnected or the fuel filters have been replaced, the fuel system must be primed to remove any air from the system.

1. Turn the ignition key to the 'ON' position to activate the fuel shut-off valve.

2. Open the primer (hand) pump on the fuel filter/ water separator and pump fuel into the filters until fuel begins to seep out of the vent on the primer pump shaft. Close the primer pump and wipe up any spilled fuel.

3. Refer to the engine manufactures operation manual for more information on priming the fuel system.

FUEL TANK STRAINER This is a stainless steel fuel strainer, screwed on to the inlet pipe of the engine fuel feed line inside at the bottom of the fuel tank.

Changing or cleaning the strainer: 1. Park machine on level ground, install articulation lock pin, lower cutting head to ground, stop engine, engage parking brake and block wheels.

2. Drain the fuel tank. (plug in bottom).

3. Remove the round fuel tank cleanout cover plate and O-ring from the access hole.

4. Before removing the strainer, clean any debris from the bottom of the tank and wipe it clean.

5. Remove the fuel strainer using the hex on the end of strainer. Carefully clean the strainer (it may be damaged by rough handling).

718E-060

FUEL TANK STRAINER

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.

6. Check for a buildup of foreign materials where the strainer threads on to the pipe and elbow.

7. Reinstall the strainer using the hex on end.

8. Reinstall fuel tank cover plate with O-ring.

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

9. Refuel and check for leaks. Start the engine and check for leaks again.

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.

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 prefiltered prior to adding it to the machine.

It is extremely important that the fuel be kept clean and free of dirt, water and any other contaminants. Use only clean prefiltered fuel to refuel this machine. Refer to the engine manufacturer's operation and maintenance manual for fuel specifications and recommendations.

The air cleaner on this machine uses two filter elements; a primary element and a safety element accessible in the hydraulic pump compartment.

AIR INTAKE PRECLEANER

ENGINE 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. This precleaner is self powered and self cleaning requiring virtually no maintenance.

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

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

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

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

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

3.22

Tigercat 718E Feller Buncher

Lubrication and Maintenance

This valve should be replaced every 1000 hours.

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

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

SAFETY ELEMENT

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

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in THIS SECTION, 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 may actually be more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

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

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

PRIMARY ELEMENT 726D-006PLT AIR FILTER ELEMENTS IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Release the cover latch gently to reduce the amount of dust dislodged.

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

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.

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

4. Always clean the inside of the outlet tube.

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

EVERY 125 HOURS Check the Engine Air Intake System components (including the charge air cooler) rubber elbows, connector hoses, tubes and clamps for damage, hardening, wear, cracks, leaks, loose clamps or loose hanger bracket hardware and repair immediately.

6. Inspect the new filter for damage.

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

Also check the Charge Air Cooler for damage, wear, cracks, or leaks and repair immediately.

8. Check connections and ducts 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.

MIDDLE AND REAR DRIVE SHAFT SPLINE LUBRICATION When operating in extremely wet or dusty conditions or when the regular service schedule has been neglected, insufficient lubrication to the spline area of the middle drive shaft will result in premature wear. In addition old grease often forms into a semi-solid, rubber-like plug preventing the purging of contaminants (water, dirt, sand, etc.) through the slip spline seal.

726M-012

The most common cause of joint and slip spline failure is lack of proper lubrication.

REAR SLIP SPLINE

726M-009

REAR SLIP SPLINE LUBRICATION Apply grease to grease nipple (1) until new, clean grease appears at the relief hole at yoke end of slip spline, FIG. 'C'.

Plug or cover relief hole and continue to apply pressure to grease nipple until new, clean grease appears at slip spline seal.

If grease does not appear at slip spline seal and continues to exit from the covered relief hole, remove the drive shaft and inspect for "hardened" grease build up, rust or other contaminants within the drive shaft. Repair or Replace drive shaft.

START-UP PROCEDURE AFTER MAJOR MACHINE MAINTENANCE

1. Check oil levels in the engine, the pump drive gearbox and the transmission.

This procedure should be followed:

2. Check coolant level in the radiator.

•

After major service or a rebuild.

•

Whenever the machine has been drained of hydraulic oil.

•

When any major component has been removed, repaired or replaced.

•

If the engine fuel supply has been disconnected or drained, refer to priming fuel system procedure in this section.

3. Do a final inspection of all fittings and clamps to make sure they are tight and will not leak.

4. Install the articulation lock bar and engage parking brake.

5. Do not start engine. Purge air from hydraulic system as follows: •

Ensure all filters are in place.

•

Remove the plug on the top case port of the drive pump. This port will assist in venting air as hydraulic oil is filling the system components. Reinstall the plug when hydraulic oil free of air begins to flow out the port.

•

Fill the hydraulic tank if it has been drained.

•

Fill all the pumps and motors with prefiltered hydraulic oil through the highest case drain ports and close the ports.

NOTE: If the axles were drained of oil, refer to FILLING THE AXLES in this SECTION and SECTION 8 of THE SERVICE MANUAL. NOTE: Changing strainers, filters and replacing the hydraulic oil tends to aerate the oil. For maximum pump life, the machine should sit for 1 hour after servicing to allow entrained air to escape from the oil prior to applying working pressures to the pumps.

6. Proceed to MACHINE START-UP procedure.

MACHINE START-UP

NOTE: If charge pressure gauge does not indicate a rise in pressure, check for possible cause (air in system, leaks, loose hose fittings, pumps not turning, etc.). Repair problem.

Repeat step 5 until a rise in charge pressure is noticed.

Before beginning this procedure, perform the PRE START-UP AND FILLING steps.

NOTE: When the saw head is attached, retorque all teeth (See saw manual). Attach the SAW BLADE GUARD and insert the SAW BLADE LOCKING PIN.

6. Reconnect engine wiring harness multi-pin connector.

1. Ensure the articulation lock bar is installed.

7. Start engine. If charge pressure does not rise within 20 to 30 seconds, TURN ENGINE OFF. If charge pressure is between 18-31 bar (260-450 psi.), run engine at IDLE for 20 minutes. Check engine oil pressure in cab. Do not operate any functions.

DISCONNECT THE MULTI-PIN PLUG FROM THE ENGINE CPU

8. With engine at IDLE, parking brake ON, hold foot brake down, bleed brakes in rear axle.

724E-020

2. Disconnect the engine wiring harness multi-pin connector (prevents engine starting).

CAUTION Machine operator must ONLY take directions from the person doing the set-up.

9. On machines 7180901 to 7181080 and 7181103 to 7181108, hold both differential locks ON and run engine at IDLE for 30 minutes to purge air and fill axles with oil (axles fill with leakage from differential locks).

If wheels are not on, operate forward and reverse pedals very slowly with differential locks on to fill axles with oil.

IMPORTANT!

Without a felling head attached, the tilt function can cause damage to the arms.

Watch the two LINK ARMS very carefully, as they may drop down beside the boom arms and wedge, causing the crank arms to bend.

When necessary, lower the boom DOWN, watching closely and tilt FORWARD, again watching the link arms closely.

INSTALL A 0 - 70 BAR (0-1000 PSI) GAUGE AT ‘M3’ PORT.

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.
