Safety

WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints (example: eczema). Always observe strict hygiene.

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

Observe the following when working with oil: • Oils used in this machine may be hot enough to cause serious burns.

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

• Avoid contact with oil, particularly heated oil.

• Wash off oil on the skin immediately with soap and water.

• Wear protective gloves. Clean hands before putting on gloves. Apply protective cream to the hands to make washing easier.

• Don't put oily rags in your pockets.

The following procedures are recommended when inspecting equipment subjected to high temperatures such as fire: • Visually inspect any seals or gaskets which have suffered from heat damage. They will appear black and sticky. If these are found, do not touch!

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

• Change oil soiled clothing as soon as possible.

• Always keep an extra overall handy, but not in the machine where it can become dirty.

• Attend to cuts and abrasions immediately. Clean them and apply first-aid.

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

• Avoid breathing in oil fumes.

• Wash hands and arms frequently, for example, at each meal break or as often as possible.

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

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

Safety

Tigercat TH570 Harvesting Head

SAFETY HAZARDS – OPERATING • Maintain a charged fire extinguisher on the vehicle at all times and know how to use it.

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

• Be aware, when performing service and maintenance tasks, surfaces and grab handles in and around the engine and cooling system may become very hot when the engine has been running.

Contact with hot surfaces may cause injury.

• Do not allow anyone who may be unfit, physically or mentally, or who may be under the influence of alcohol or drugs, to operate the machine.

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

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

• Read, understand and follow all general safety precautions specified in the ATTACHMENT MANUFACTURER'S DOCUMENTATION.

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

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

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

• Maintain a minimum distance of 3 m (10 ft) between the machine, including the boom or attachment, and any power line carrying up to 50,000 V. Add 1.5 m (5 ft) for each 150,000 V increment beyond 50,000 V. For example, if a power line carries 350,000 V, keep back at least 6 m (20 ft).

WARNING

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

Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Wash hands after handling.

• If the machine must be transported, adequately secure it to the transporting vehicle. Refer to VEHICLE MOVING AND TRANSPORTING INSTRUCTIONS literature supplied with the machine.

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

Reduce engine speed to LOW IDLE and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed.

This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

Safety AVOID INJURY FROM BACKOVER ACCIDENTS

CAUTION

Lead-acid batteries contain sulfuric acid which can severely damage eyes or skin on contact.

Always wear a safety face shield, rubber gloves and protective clothing to reduce risk of accidents.

Before moving the machine, be sure all persons are clear of the area.

• Always be alert for bystanders moving into the work area. Use the horn to warn bystanders before moving the machine.

Lead-acid batteries produce flammable and explosive gases. Keep arcs, sparks, open flames and lighted tobacco a safe distance from the batteries.

• When using a signal person, keep the person in view at all times. Always be sure the signal person is clear before backing up.

• If acid is accidentally splashed into your eyes, flush immediately with clean water and get medical attention.

• To avoid backover accidents: • Always look around before you back up. Be sure everyone is clear.

• Do not attempt to charge a frozen battery. It can explode.

• Keep the machine motion alarm in working condition. The motion alarm must sound when the machine is moving forward or in reverse.

• Use a signal person when backing up if the view is obstructed. Always keep the signal person in view.

• Learn the meaning of all flags, signs and markings on the job site and who is responsible for signalling.

• Before servicing the machine, remove the negative (−) battery terminal cable (to the starter motor) from the battery.

• When service is complete, connect the negative (−) battery terminal cable and turn ON the battery disconnect switch.

• Do not short out the battery terminals for any reason.

Serious burns or an explosion can result.

1.9

• Keep all windows, mirrors and lights in good condition.

Safety

Tigercat TH570 Harvesting Head

OPERATING SAFETY PRECAUTIONS

CAB EXITS There are three ways to exit the cab in case of an emergency.

1. Front Door– This is also the main point of entry and is the only door that should be used under normal operating conditions to enter or leave the cab. This door is also equipped with a safety interlock switch.

See safety interlock switch on front door in machine operators manual.

• Turn OFF the engine when refuelling – do not refuel the machine while smoking or near an open flame or sparks.

• Check that no other personnel have moved into a hazardous area before starting the machine.

• Sound the machine horn before starting the machine.

2. Side Door– This door should be used for emergency exits only. Do not use this door to routinely enter or leave the cab. This door is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. ALWAYS turn OFF engine before using the side door exit.

3. Escape hatch – This is a third cab exit for use if the side exit or front door exit become blocked. This hatch is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. Always turn OFF engine before using the escape hatch exit.

IMPORTANT! The operator of the machine must be familiar with these emergency exits and how to use them.

• The operator’s seat is equipped with lap and shoulder harness belts. Use both of these restraint systems at all times when operating the machine.

• Start the engine according to the instructions in the manual. Refer to OPERATING MACHINE in SECTION 2 of the MACHINE OPERATOR'S MANUAL.

WARNING Never use a liquid starting aid to start an engine.

This machine is equipped with a computer controlled heating element in the engine intake system. Starting fluids will explode on contact with the heating element.

All operators should practice using all the cab exits to become familiar with escape procedures should they need to perform them in the dark, when the machine is in a rolled position, or other possible adverse condition.

All three exits should be checked to make sure that they are operational and will function in an emergency. The safety interlock mechanism on the front door or the side door and escape hatch retaining mechanisms must not be tampered with or defeated.

IMPORTANT! Unlock both doors before operating the machine to allow opening from the outside in case of an emergency. Make sure the doors are operational. Open the doors twice; once using the exterior latch handle and once using the interior handle.

For additional information, refer to EMERGENCY EXITS in the MACHINE OPERATOR'S MANUAL.

• Before moving the machine to the work site, check to ensure that all doors, panels, and access covers are installed properly and secured.

HARVESTING ATTACHMENT – GENERAL SAFETY

• Always fell trees in the direction that they are leaning.

Improper operation, maintenance or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any maintenance or repair of this product until you have read and understood the operation and repair information contained in the manuals provided by the attachment manufacturer.

The following are general safety guidelines for harvesting attachments. Note the design, operation, and maintenance of attachments varies among manufacturers. Always follow the specific safety, maintenance, and operating procedures provided by the attachment manufacturer.

The operator of the carrier and harvesting head must be properly trained in the operation of the equipment and its safety requirements.

PRIOR TO STARTING OPERATION

• Never fell trees close to overhead power lines, vehicles, houses, roads/pathways, etc.

WARNING The operator must release trees from the attachment, place attachment on the ground, and shut pilot system off if someone enters into the hazard zone.

• Never fell trees when there are personnel on the ground within the 150 m (500 ft) “hazard zone.”

• During operation do not allow anyone within the safety zone of at least 150 m (500 ft) from the machine.

• Never fell trees in the direction of the operator’s cab.

WARNING

WARNING

Avoid the risk of chain shot. Never operate the attachment so the saw bar is directly in line with the cab or any personnel!

The attachment may release held trees when the cab front door is opened, the pilot system is turned off or the fire suppression system is activated. Never exit the cab with a tree suspended in the attachment.

• Ensure no one is near the machine where the risk of personal injury is present.

• Ensure no one is in the line of the chain saw when starting or operating the harvesting head. The hydraulically driven saw chain reaches high speeds and is an extreme hazard if the chain breaks.

• Do not process trees with the saw guide (bar) aligned with the operator’s cab. The hydraulically driven saw chain reaches high speeds and is an extreme hazard if the chain breaks.

• Operate so the chip discharge area of the harvesting head is not directed at people, livestock, houses, buildings, roads or other machines.

WARNING

• Regularly inspect, check and maintain the saw guide (bar), the saw chain and sprocket, ensuring that all components are secure and not damaged as detailed in the harvesting attachment operator’s manual.

• Ensure that all safety equipment upgrades available from the attachment manufacturer have been installed.

• Before starting each shift the operator must test ALL functions of the carrier and attachment to ensure that they are in proper working order.

• THROWN OBJECTS HAZARD. • KEEP CLEAR AS HIGH SPEED EJECTION OF CHAIN SAW PARTS CAN CAUSE SERIOUS INJURY OR DEATH. • NEVER POSITION HEAD SO THAT CHAIN SAW BARS ARE IN LINE WITH ANY BYSTANDERS, OTHER MACHINES OR CAB. 29921A R1

OPERATION Felling trees with the harvester is very dangerous and should be done only by properly trained and experienced operators.

• Lower attachment to ground into park position and turn pilot system off whenever machine is not in use.

1.11

• Be particularly observant with the zone in line with the chain saw.

Safety HARVESTING HEAD CONTACT WITH CAB

Tigercat TH570 Harvesting Head Working with the harvesting head in close to the machine: • Increases operator visibility, permitting better placement of the head on the tree and improving awareness of saw bar location and penetration, tree species and areas of rot, splits and crooks.

• Reduces the potential for damage to both the standing trees and the harvesting head and stick boom components.

• Improves the stability of a machine working on uneven ground as the weight of the boom, head and tree need not be extended as far out in front of the machine.

The boom of this machine is designed to enable the harvesting head to be tucked in close to the operator’s cab. This ability maximizes the manoeuvrability of the harvesting head to work around standing trees and while thinning in dense stands. See both the upper and lower sections of Figure 1.

• Broadens the working area that can be reached by the boom and thereby lessens the need to reposition the machine as frequently during harvesting operations.

Safety

Working with the harvesting head in close to the machine also increases the chances of the harvesting head making contact with the front area of the cab, particularly if the head is swinging backwards as it dangles from the end of the stick boom. See both the upper and lower sections of Figure 2.

Should contact between the harvesting head and the cab occur at any time during the operation of the machine, the following procedure must be completed.

For all machines equipped with a harvesting head, the following procedures must be followed during the operation of the machine to avoid contact of the harvesting head with the cab.

2. Refer to CARE OF POLYCARBONATE WINDOWS IN CAB and INSPECTION AND MAINTENANCE in SECTION 3 of the MACHINE OPERATOR'S MANUAL.

1. Inspect the cab, the front door and the front window immediately to determine if any damage has occurred.

1. When nearing boom positions shown in Figure 1.

• Always keep the head in the upright harvesting position.

• Do not tilt the head from the harvesting to the processing position as the saw housing may contact the cab.

• Reduce the speed of boom movement. Rapid movement could cause the base of the harvesting head to swing backwards towards the cab.

• Avoid any sudden movements with the track drive system as this could cause the head to swing backwards into the cab.

2. Never bring the harvesting head in close to the machine while the harvesting head is swinging on the end of the stick boom. See Figure 2.

3. Do not use the head to pull downed trees directly towards the cab. If the clamping arms slip on the tree, the head may quickly swing towards the cab.

CHAIN SHOT – LOGGING SAFETY

HOW CHAIN SHOT OCCURS

Chain Shot is the high-speed ejection of chain parts that can occur in the event of a derailed or broken chain.

While the risk of a chain shot event can't be eliminated, it can be minimized by following some simple operational recommendations.

A

WARNING There is risk of serious injury or death to machine operators and bystanders from chain shot. Follow the manufacturer's application and maintenance instructions and those provided for the equipment on which the cutting chain is used.

Generally, chain shot originates near the driven end of the cutting system, but can also originate from the guide bar tip area. In either situation, it poses the same risk of serious injury or death to the machine operator and any ground personnel nearby.

1.14

Tigercat TH570 Harvesting Head

Safety CAN CHAIN SHOT BE ELIMINATED?

WARNING

In simple terms, no, it can’t. Properly designed chain shot guards and shields reduce the danger of a chain shot from the drive sprocket area. However, there is currently no known way to place similar guards in the guide bar tip area without significant disruption to the cutting operation. Because no guarding is currently possible in the guide bar tip area, chain shots can be generated and pose the same risk of serious injury or death as those generated at the drive sprocket area.

CHAIN SHOT HAZARD! It is the operator's responsibility to ensure any bystanders and themselves are not in the plane of the cutting chain.

Orient bar and chain so high velocity parts are thrown away from people and equipment.

Refer to applicable manuals for additional safety information

Care should be taken to minimize the exposure of the machine operator and ground personnel to the cutting plane of the cutting system and Shot Cone Zone.

Ground personnel should stay back at least 150 m (500 ft) away and outside the Shot Cone Zone of a working harvester.

A

A 575-502

A Cutting Plane

Saw chain pieces usually travel in the cutting plane of the guide bar, but can deviate to either side. Although the 'Shot Cone Zone' reflects the most likely chain shot path, deflection can occur, substantially expanding the distance and area chain pieces may travel.

860C-446

A 150 m (500 ft)

Hazard Zone

Chain shot projectiles travelling at the speed of a bullet can travel far beyond the above recommended stay back distance.

The stay back distance will help reduce the risk of a chain shot injury, but not eliminate it.

The following items should be observed in accordance with the saw manufacturer's recommendations: • Cutting system maintenance.

• Saw chain maintenance.

575-503

• Clean and dress guide bars on a regular basis.

• Replace worn drive sprockets.

1.15

Safety Do not exceed the manufacturer’s recommendations for chain speed. Cutting systems must be inspected frequently. Dull, damaged saw chains should be immediately removed from service for inspection, repair or replacement. Saw chain loops which have broken twice, must be removed from service.

Drive sprockets must be aligned with the groove of the guide bar. Ensure the saw chain/guide bar lubrication system is functioning properly: 0.404-pitch cutting systems should use approximately 7.6 L (2 US gal) of guide bar/chain lubricant or more per eight hour shift in harvesting operations - more when used in processing operations. Three-quarter-pitch cutting systems should use approximately 9.5 L (2.5 US gal) or more per eight hour shift in harvesting applications - more when used in processing operations.

Tigercat TH570 Harvesting Head IN COLD CUTTING CONDITIONS • Use a lighter weight lubricant, if possible, doubling the flow rate.

• Periodically cycle the guide bar without cutting (air cuts), this increases lubricant present on the cutting system.

• Reduce bar feed force.

CONDUCT PROPER GUIDE BAR MAINTENANCE • Clean the guide bar groove from bar tip to bar tail and keep the oil hole open.

• Turn the guide bar over on a daily basis to equalize wear.

OPERATIONAL RECOMMENDATIONS

• Cycle the guide bar several times to remove moisture from the guide bar tip.

IN GENERAL

• Maintain proper chain tension, checking it often.

• Never begin a cut with the machine operator and ground personnel in the Shot Cone Zone.

• Always begin a cut as close to the ground as possible.

• Always use new and approved parts when assembling and repairing chain.

• Maintain chain in agreement with chain manufacturer’s recommendations.

• Never force a dull chain to cut. A sharp chain places less wear and tear on the cutting system.

• Chain should be sharpened or replaced with a sharp chain at least once per operational shift, or more often if damaged.

• During work breaks and at the end of each shift, relieve chain tension to prevent damage to the guide bar tip, saw motor and/or the chain as the chain cools and contracts.

• Reduce chain speed.

In simple terms, your harvester head, when operational, should be treated as if it is two loaded guns (the bar tip and the bar tail) that pose a risk of serious injury or death to the machine operator and ground personnel.

The risk of a chain shot event cannot be eliminated, but the risks can be reduced by following the recommendations provided by your cutting system manufacturer, and the operational recommendations presented here.

• Depth gauges (rakers) must be maintained through the life of a chain.

• Never exceed your chain manufacturer’s operation recommendations.

FLUID INJECTION INJURY WARNING

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.

Diesel fuel or hydraulic oil under pressure can penetrate the skin and cause serious personal injury, blindness, or death. If any fluid is injected under the skin, it must be surgically removed within a few hours by a doctor familiar with treating this type of 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 occurs, a fine, high velocity stream of fluid will result.

Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.

Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation. There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun.

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

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

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

SEARCHING FOR POSSIBLE FLUID LEAKS: • Do not search for leaks with your bare hands.

Always wear thick protective gloves.

• Always wear safety goggles for eye protection.

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

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

• Place the end of a long piece of wood in the suspected path of any fluid stream. Do not use any part of your body.

• Recognize 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.

• Do not grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

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

• Do not use any hoses that you suspect could be defective.

Tigercat TH570 Harvesting Head

Safety

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 – 400 bar (246 – 5801 psi). It takes less than 7 bar (100 psi) to inject a substance through human skin.

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

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

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.

• Install protective shrouds 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

LIGHTNING SAFETY

WHAT IS A LIGHTNING STRIKE?

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.

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 ft) 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.

Loggers can increase their chances of avoiding a lightning strike by following a few simple safety practices: • Designate a member of your crew to: • Monitor daily weather forecasts • Observe local weather conditions • Alert all other members of the crew when a possible lightning threat develops • Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

• 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.

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

• 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, seek shelter there first.

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.

1.22

Tigercat TH570 Harvesting Head

Safety

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

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

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.

IF INSIDE A MOTOR VEHICLE OR FULLY ENCLOSED ROPS EQUIPMENT CAB: • Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

• 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.

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.

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

IF YOU ARE CAUGHT OUTSIDE AND HAVE NOWHERE TO GO:

Note 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.

WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER IF YOU CAN, GET INSIDE:

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

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

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

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

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

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

• Avoid entering any small enclosures or shelters.

IF INSIDE A BUILDING:

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

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

• 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.

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

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

• Do not use the telephone except for emergencies.

1.23

Safety

Tigercat TH570 Harvesting Head

WHAT TO DO IF YOU FEEL YOUR SKIN TINGLING, YOUR HAIR STANDS ON END, LIGHT METAL OBJECTS VIBRATE OR YOU HEAR A CRACKLING SOUND: • Lightning is probably about to strike. You only have a few seconds to act.

• 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.

• 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: • The victim does not carry any electrical charge.

There is no danger to anyone helping this person.

You can touch him or her immediately.

• Call your local emergency response telephone number immediately.

• If the victim has no pulse, their heart has stopped or they have stopped breathing, call for professional medical help immediately and then begin administering appropriate first aid. Use a portable defibrillator if one is available (as required).

• 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

FIRE PREVENTION

• Clean out all accumulated forest debris (twigs, pine needles, branches, bark, leaves, sawdust, 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.

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris 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.

Use the following fire prevention guidelines to supplement the operator’s fire prevention efforts. In no case are the guidelines to be used, or assumed, to be 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: • Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. • 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 COOLER Package, CLEANING in SECTION 3 of the MACHINE OPERATOR'S MANUAL. • 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 is vital after blow-off to ensure thorough cleanliness. Engine exhaust systems provide numerous small pockets where sawdust, 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.

• 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.

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

• Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic oil 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.

• Use only non-flammable solutions for cleaning the machine and components.

• 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. All exhaust leaks or defective parts must be repaired immediately.

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

• 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. When exhaust leaks occur during operation, shut down the machine immediately and do not put it back to work until the necessary repairs have been completed.

• Park the machine at least 15 m (50 ft) away from other equipment at the end of each shift.

• Do not leave the machine parked with boom, arch or blade suspended off the ground. If supporting hydraulic hoses burn through during a fire, they will inject pressurized hydraulic oil into the fire causing the boom, arch or blade to fall rapidly to the ground.

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

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

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

FIRE PREVENTION

Tigercat TH570 Harvesting Head • Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic oil tank compartments and all machine belly pans at least once each month, or more frequently when working in conditions with high volumes of forest debris • Use only non-flammable solutions for cleaning the machine and components.

When working in a forest environment combustible debris will collect in tight corners of the machine. Left unchecked, this debris may cause a fire; when mixed with fuel, oil, or grease in a hot or confined place, the danger of fire greatly increases.

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.

• Maintain a charged fire extinguisher on the machine at all times. Know how to use it.

• Remove dust and debris regularly from the air intake doors, cooling system components, and A/C condenser to prevent engine and hydraulic system overheating and to maintain efficient operation.

Refer to CLEANING COOLER PACKAGE in SECTION 3 .

• Remove all forest debris and fine organic material around engine intake and exhaust components (turbocharger, exhaust manifold, exhaust pipes, muffler) at the end of each shift, or more frequently when working in conditions with high volumes of combustible forest debris. Check carefully in small pockets and cavities around the engine enclosure where smouldering debris may gather.

NOTE: Minor debris accumulations near hot components can ignite and smoulder. Smouldering debris may shift and cause fire to spread.

• Clean out all accumulated forest debris (twigs, needles, branches, bark, leaves, saw dust, wood chips) and any other combustible materials from inside the machine belly pans, lower machine structures, and engine, hydraulic, and fuel system areas no less frequently than at the completion of each work shift.

• Inspect the machine regularly for evidence of diesel fuel or hydraulic system leakage. Check for worn or damaged hydraulic and fuel lines before turning on the engine.

• Clean up any grease, diesel fuel, or oil spillage (hydraulic or lubricating) immediately.

• Inspect the exhaust system daily for evidence of leakage. Check for worn, cracked, broken, or otherwise damaged pipes or muffler, and missing or damaged bolts or clamps. Make repairs immediately. Engine exhaust leaks can cause fires.

Do not operate the machine until exhaust leaks are repaired.

NOTE: Changes or increases in engine exhaust noise levels often indicate exhaust leaks. Do not ignore these warnings. Shut down the machine immediately and complete repairs.

• Park the machine at least 15 m (50 ft) away from other equipment at the end of each shift.

• Never leave the machine parked with the boom raised off the ground. Should the hydraulic cylinder hoses burn through in a fire, hydraulic oil will escape and the boom will fall rapidly to the ground.

• Turn OFF the battery disconnect switch when parking the machine.

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

• Remove the ignition key, and lock the cab and fuel cap at the end of shift to reduce the risk of vandalism or theft.

• Do not smoke in the vicinity of the machine.

• Do not smoke during fuelling operations, when the fuel system is open to the atmosphere, or when servicing the batteries. Exercise caution if smoking in the woods.

• After transporting a machine by road, open all doors and access panels; remove any debris that may have settled around the engine and exhaust system during the journey.

• Before undertaking repair work or welding, clean the surrounding area and place a fire extinguisher within easy reach.

• Store rags and other combustible materials safely in a fireproof location.

• Do not operate the machine near burning timber. Do not use the machine to push burning timber into a pile.

• There is no substitute for fire prevention. Time invested in prevention is repaid through productivity on the job site.

1.26

Tigercat TH570 Harvesting Head

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

NOTICE Equipment fires undermine productive logging, may increase your insurance premiums dramatically, or prevent you from obtaining insurance coverage. Make fire prevention a priority.

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

HOW TO PREPARE FOR A MACHINE FIRE • Inspect and maintain all machine systems on a routine basis.

• Maintain fire extinguishers in proper working order. Follow the manufacturer’s instructions for inspection and maintenance (on the label of the fire extinguisher and in the user's manual).

• Verify that any pressurized water systems on the machine are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE as applicable in SECTION 3.

• Verify the correct types of fire extinguishers are available at the work 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.

• Know how to use the fire extinguisher, the pressurized water system (as applicable), and the fire suppression system (as applicable) on your machine. There is no time to read instructions during a fire emergency. Be prepared to act.

• Keep emergency contact information readily available in case of fire.

IN CASE OF A MACHINE FIRE If a machine fire occurs: 1. Lower all working attachments to the ground.

2. Turn OFF the engine.

NOTE: If equipped, use the Emergency Stop Button to override the Hot Engine Shutdown Prevention Strategy.

Activate the fire suppression system as applicable.

3. Radio or call for help. Report a fire immediately.

4. Turn OFF the battery disconnect switch if it safe to do so.

5. Dismount the cab; take the fire extinguisher and pressurized water system hose (if applicable) with you.

• Class C fires apply to energized electrical equipment.

• The nozzles on fires extinguishers and pressurized water systems (if applicable) must fit within the fire extinguisher access ports on the machine doors.

• Keep the fire detection system in working order as applicable. Refer to fire DETECTION system in SECTION 2.

6. Put your personal safety and the safety of other persons first. Approach any fire with extreme caution. All fires are potentially very dangerous and life threatening.

Before deciding to fight the fire, be certain that: 7. The fire is small and not rapidly spreading.

• Keep the fire suppression system charged and in working order as applicable. Refer to fire suppression system in SECTION 2.

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

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

• Know the recommended fire procedures in your organization's emergency action plan.

• Follow all national, state/provincial, and local fire fighting regulations. Regulations will vary from region to region but most will require that: • Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

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

1.27

If in doubt about your ability to fight the fire, do not attempt to fight it. Stay well back. Wait for help to arrive.

NOTE: Engine coolant, diesel fuel, or hydraulic hoses may fail during a fire. Hot coolant, fuel, or oil could be ignited, or may spray at high velocity from damaged hoses.

Safety

Tigercat TH570 Harvesting Head

When fighting a fire:

AFTER A MACHINE FIRE

1. If possible, use a dry chemical fire extinguisher or fire suppression system first.

Before returning a machine to operations:

2. 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 debris or hot machine components in the area. Water cools the area, reducing the chances of re-ignition.

3. Use the fire extinguisher PASS method: Pull the safety pin at the top of the extinguisher that prevents the discharge lever from being depressed.

Break the plastic seal as the pin is pulled.

Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. To put out the fire, the fuel must be extinguished, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

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

1. Determine the cause of the fire.

2. Complete all necessary repairs.

3. Service and recharge the fire suppression and detection systems as applicable.

4. Report the fire to your dealer and/or Tigercat Industries Inc. by completing an incident report (Tigercat form 5101).

NOTE: Fire detection systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine.

NOTE: Dry and wet chemical fire suppression systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

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

822C-190

Typical Fire Extinguisher Access Port

4. Insert the fire extinguisher nozzle into the appropriate access port and discharge the extinguisher.

5. If it is safe to do so, open the access panels in the area of the fire and aim the extinguisher directly at the base of the flames.

6. If it is impossible to reach an access port or to open a panel or door, discharge the extinguisher through mesh screening or any available opening.

7. Monitor the machine after extinguishing a fire in case of re-ignition; remain until help arrives.

1.28

Tigercat TH570 Harvesting Head

Safety

DRY CHEMICAL CLEANUP PROCEDURES ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder. The powder comprises very fine particles that penetrate and cover all components in the vicinity of the discharge.

Areas in contact with dry chemical power must be neutralized and cleaned after a fire. Wear protective clothing, safety goggles, and a fine particle dust mask.

1. De-energize electrical systems prior to any cleanup.

2. In areas that remained cool and dry during the fire, the dry chemical remains in powder form.

Clean these areas immediately to prevent residual powder from coming into contact with water or ambient moisture.

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.

Wipe all surfaces with a damp cloth.

3. In areas exposed to moisture during the fire, the dry chemical powder combines with water to form a paste that is mildly acidic. All surfaces covered in dry chemical paste, including electrical contacts, are vulnerable to corrosion.

Neutralize the acidic paste on large surfaces by spraying or washing these areas with a mixture of three parts hot water to one 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.

Clean electrical contacts with a contact cleaner that has no flash or fire point and is non-corrosive and non-conductive, such as CRC Contact Cleaner 2000.

4. In areas exposed to heat during the fire, the dry chemical powder melts, 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.

When exposed to moisture the caked dry chemical is also mildly acidic. When the breakdown procedure has been completed, follow this immediately with the neutralizing procedure as described in step 3.

1.29

WET CHEMICAL CLEANUP PROCEDURES The wet chemical suppression fluid contains frost protection, rust inhibitor, and film-forming liquids that are broken down by natural organisms. When the fluid dries, the corrosion protection loses its effect. Clean up wet chemical discharges as soon as possible to avoid corrosion on metal parts.

If the suppression fluid is sucked into the engine air intake, it will not significantly change engine functioning.

However, starting difficulties may occur with diesel engines because the suppression fluid contains water.

The suppression fluid also may cause corrosion damage if the engine is not cleaned soon after a fire.

Clean affected areas promptly to protect electrical system functions and prevent short circuits.

To clean affected areas: 1. Flush the affected area with pressurized fresh water.

2. Use an alkaline washing detergent to remove the film. (Film residue attracts dirt and other impurities on affected surfaces.)

3. Flush affected areas a second time to remove detergent residue.

NOTICE To protect engines, electrical installations, and other metal parts against corrosion, flush the remains of dried or moist suppression fluid as soon as possible after the release of the piston accumulator (use a high pressure washer if possible).

CONTROL SYSTEM COMPONENTS

H. CONTROL HANDLES Two control handles are used for operator control of machine and harvesting head functions. Control handles and button arrangement vary depending on option selected. See CONTROL HANDLES in this section.

A. CAB ELECTRICAL CONTROL BOX The electrical control box mounted on the cab wall behind the operator’s seat houses the main controller and the joystick input module.

The electrical terminal assembly (E) contains fuses for various circuits, and wiring connections for the main controller and joystick modules.

IMPORTANT !

Prior to operating the machine, navigate to the “Keypad Status/Test” page to check the keypad layout and familiarize yourself with the button functions for the current operator.

There are two primary switches on the electrical control box. A red locking switch (F) on the top left of the box, and a black switch (C) with a green LED on the bottom right of the box. The red locking switch is a service disconnect, which must not be switched unless the system has been shut down for over 90 seconds and only power # 8 LED on the main controller is on. The only case for switching the service disconnect is when welding work is required or for long term storage. The switch will isolate the valuable measuring system components. The black switch controls initialization of the system and display.

I.

D5 PRIO DISPLAY The computer display is located in the cab typically on the left side facing the operator. It has a multifunction colour display with touch screen functionality.

J. D5 PRIO PC/OPTIMIZATION DISPLAY This computer display is located in the cab and used with the Prio PC/Optimization operating system. It has a multifunction colour display with touch screen functionality.

K. HEAD ELECTRICAL BOX The head electrical box is located on the harvesting head and contains fuses for each module and a terminal strip for making connections between the modules and solenoids on the head.

IMPORTANT !

If welding must be done, shut down the Tigercat D5 measuring system fully as described below. Failure to follow this procedure will result in irreparable damage to valuable measuring system components.

L. D5IO12 (AG046) INPUT-OUTPUT MODULES Two input‑output modules are attached to the head electrical box that control output to coils for all functions. The modules receive instructions from the main controller via CAN 1. They are active only when the carrier pilot system is active.

PROCEDURE FOR FULL SYSTEM SHUTDOWN 1. Turn the ignition off.

2. Turn off the battery disconnect (if equipped).

3. Turn off the system switch (C).

4. Wait at least 90 seconds for the computer to back up.

M. D5CI12 (AG055) HEAD CONTROLLER The head controller has inputs for all head sensors and communicates with the main controller and input‑output modules via CAN 1. The head controller is active only when the carrier pilot system is active

5. Turn off the service disconnect switch (F).

B. D5MC-F (AG060) MAIN CONTROLLER The main controller is the computer for the complete Tigercat D5 measuring system. The main controller communicates with all other modules via the CANBUS, interfaces with the display via DVI and USB cables, and has USB interface for the printer, license key, and memory stick transfers.

D. D5IO48 (AG054) CONTROL HANDLE INPUT MODULE The control handle input module is located in the electrical control box. This module accepts input from the control handles and communicates with the main controller via CAN 2.

G. PRINTER (OPTIONAL) This is an optional device for typically printing harvesting related details. It is located in the cab to the right of the operator’s seat. The printer connects to the main controller through one of the USB ports.

2.3

N. KEYBOARD (OPTIONAL) This is an optional item used for navigation and data entry into the measuring system. Requires the USB receiver of the keyboard to be installed into one of the USB ports of the measuring system computer.

O. CALIPERS (OPTIONAL) This is an optional item used for completing control measurements and calibrations. By comparing measurement information recorded by the Tigercat D5 system with measurements made with the calipers, recommendations are made for adjusting the calibration of the harvesting head. Requires the Tigercat D5 Prio PC / Optimization system.

Planning plays a decisive role in mechanized timber harvesting. Successful planning utilizes previous experience.

Many aspects are considered when formulating a harvesting plan. These include terrain (area to be harvested), ground conditions, waterways, soil type, erosion control, species, stem density, stem form, undergrowth, access, roading, boundaries, historic sites, environmental areas, transmission lines, gas lines, public access ways, storage sites, landings, equipment to be used, staff ability, and haul distance.

These factors all determine the way a plan is formulated to gain a safe, productive, and profitable harvesting operation.

Site inspection is necessary by operators before harvesting operations commence. Ensure all members of the harvesting team are aware of the constraints, hazards, and requirements of this harvesting operation.

Make sure the machine has been completely serviced and is in good condition with clean windows.

Inspect the saw chains: make sure they have been sharpened and tensioned and are in good condition.

Test all controls before commencing work.

Run all the functions to ensure the hydraulic components have been warmed up. If hot oil under high pressure runs through cold components, the thermal shock can cause excessive wear and/or damage.

Determine location of roads, waterways, and boundaries.

Before work begins identify additional hazards.

CLEAR-CUT HARVESTING FELLING

Tigercat TH568 Harvesting Head THE FELLING PROCESS The direction of fall is determined by the position of the head on the tree. The tree should fall in a direct line with the tilt frame.

Position the head on the tree as low as possible while gaining the correct felling angle. This requires tilting the head up and fully opening the arms of both knives and feed wheels. Then place the tree in the opening and close the knife and feed wheel arms.

A slight amount of pressure is then applied to the tree to ensure the saw will not jam as the tree is being cut and also assist with the tree fall direction.

When the saw is activated, the “Head Close” circuits will operate to ensure the tree does not move within the head while cutting is taking place. A visual indication of the cutting taking place is the chips exiting the saw box area. Keep the saw activated until the tree is ready to be dropped. Stop the saw, which automatically retracts, and apply force to the tree in the direction of fall.

The felling stage in clear-cut harvesting influences the whole operation.

The felling direction and log presentation for extraction requires careful attention in order to reduce breakage and to be able to present a well-delimbed stem for quick extraction or further processing.

To reduce breakage and provide a larger working radius, it is preferable to fell trees against standing trees to cushion the fall and reduce the amount of undergrowth around the base of trees to be felled. This is achieved by felling the tree just off-centre to a standing tree preventing the falling tree from becoming “hung-up”.

When felling, tree control is reduced if the head is at full reach. Optimum felling is achieved using the head as close as possible to approximately 3/4 of maximum reach. During these manoeuvres, the machine chassis/ undercarriage should remain stationary at all times.

Should the machine chassis/undercarriage become unstable, a reduction in reach should be applied immediately. Ensure the tracks are on a firm footing at all times, avoiding locating one or both tracks on stumps, which could allow the machine to move unexpectedly during manoeuvres.

Positioning of the machine chassis/undercarriage will determine the working envelope. Higher production is achieved through maximum ground coverage with minimal track movement. This also reduces environmental impact.

It is preferable an operator has had manual felling experience, which allows a better understanding of felling techniques.

Controls and Operation

DELIMBING

FELLING AND DELIMBING

At this point the tree is ready to be delimbed, which involves slewing the base and driving the stem through the head while obtaining the correct direction of the butt.

Once the butt has been positioned, the remainder of the tree can be delimbed by using the momentum of the base to assist the delimbing effort of the head.

To improve delimbing it is beneficial to feed the tree through while felling, allowing the weight of the tree to assist with the delimbing operation.

While the tree is falling, the drive wheels can be activated to allow the tree to pass through the head and delimb. Once the drive wheels are activated, the knife arms and feed wheel arms will automatically go into proportional clamp mode allowing the tree to pass through the head.

Ensure the head is kept to a minimum height in this operation to reduce the impact on the head from the falling tree.

To improve delimbing performance, slew into the feed direction.

WARNING Due to variations in tree weight, the operator must be aware of the machine manufacturer’s specifications in regard to the ability of the machine to safely handle the tree being processed.

Use care when swinging stems around not to allow contact with the operator’s structure, and be aware of tail swing, which could damage other trees or stems.

Ensure the delimbing knives are kept sharp and in form to reduce the effort required to remove limbs.

The delimbing procedure is about balance and stem control, which, when perfected, gives excellent results and increases production.

Do NOT feed the stem through the head while the stem is facing the operator’s structure.

It is recommended to delimb the stem with the head just high enough to position the butt and clear objects.

Operating the head too high will result in loss of control of the stem and also stem breakage.

THINNING TECHNIQUES

FULL-TREE THINNING

Felling in thinning requires the harvester to be placed approximately 2 meters up the tree and then driven down the stem. This allows the knives to provide a clear area for the harvester to grip when felling.

The procedure is similar to the above, and used in conjunction with skidding extraction.

In order to gain the maximum merchantable volume and reduce bark damage to remaining trees, different methods are used within the stand: cut to length or full length.

The pathway is harvested in the same manner at the same spacing.

CUT-TO-LENGTH AT THE STUMP A path of stems approximately 4 meters wide is felled to allow access to both the harvester and the forwarder.

While this path is being harvested, stems both sides of the path are harvested and processed.

More care is required when felling to correctly position the stem, allowing processing without damage to standing stems due to the longer lengths being handled.

The major differences is the direction the processed stems are stock piled to allow extraction with minimal damage. It is not always possible to process over the pathway, so harvesting slash is distributed over the complete swath.

Stems are stacked either side ready to be removed by the forwarder.

Decide where to stack the stems.

Fell the tree on the left and process it to the left or right. Process the stems over the path and lay the stems on the opposite side. This method results in the harvesting slash being left on the path, thus providing a load‑bearing surface for both harvester and forwarder and a clean area for the stacks.

Stems need to be processed and piled with the butts placed outwards providing easy access for extraction.

SELECT THINNING Select thinning depends on the finished crop stocking levels and the area available to manoeuvre a machine between trees.

This method also requires a reduction in paths cut from a block while still providing access for extraction.

With this system, trees can be felled consecutively left and right to reduce the amount of machine movement, ensuring stacks are positioned so the forwarder can easily load.

When stacking, use colour marking and separate piles to identify grades, which will assist the loading by the forwarder.

2.18

Tigercat TH568 Harvesting Head

Controls and Operation

CUTTING

A side tear along the tree may stop the chainsaw from returning if it is not cut on the downward pass. The cut should be made past this tear. Stems should be supported when cutting as this will avoid splitting.

GENERAL Trees with a heavy forward lean can be felled by placing multiple front cuts to create a larger area to compress while back cutting.

A small amount of upward lift may be required as the chainsaw completes the cut. This will keep the cut open and avoid chain stall.

Larger trees should be released once the tree is falling.

This will avoid harvester damage.

Care should be taken the end of the bar does not cut into the ground when completing a cut. The chainsaw may also cut into another log damaging the log, or, if the harvester head is moving, may result in damage to the bar and chain.

Tops of hills and uneven ground can also cause the tree to swing up causing the machine to lift or harvester damage.

Releasing trees as they are falling into another standing tree can sometimes allow the tree to roll off.

USING THE TOPPING SAW UNIT

If the fallen tree is hung up in another be careful when pulling it down. Watch the holding tree is not being pulled in the same direction. If so, pushing the fallen tree will release the holding tree away from the machine.

USING THE MAIN SAW UNIT

The topping saw is designed for cutting small-diameter tops off trees. The tip of the chainsaw can be pinched if larger diameters are attempted. The topping saw chain can be derailed if branches or the end of the log is under load. It is advised the topping saw bar be visible when cutting.

Before using the chainsaw • Keep in mind that • The head may go into float when the saw is activated depending on the Tilt Release setting.

• The direction of fall should be convenient for delimbing.

• The boom hydraulics and the cab should be protected.

• The chainsaw bar should remain in view if possible.

• Ensure the tree is clamped. A loose tree may move after the chainsaw begins the cut. This may derail the chain or stop the chainsaw from cutting.

While cutting, push in the felling direction avoiding upward pressure. As the cutting unit completes the cut, the saw will increase in speed and bark chips may be visible.

Once the cut is completed, release the saw button and the saw will return automatically.

When felling it is possible to jam the saw. Stop the activation of the saw and slowly lift the head supporting the weight of the tree. The lifting distance should be just enough to release the saw.

Check that the saw has returned by the saw home indicator before moving the tree too far.

PROCESSING

SPECIAL TECHNIQUES

GENERAL

In instances where crutched trees, multi leaders and other abnormalities are encountered during felling, delimbing, and processing, it may be necessary to use special techniques to safely handle stems with minimal damage to the machine

When working on confined landings ensure safety procedures and practices are in place and adhered too.

Do not process toward the cab.

Once the tree has been delimbed, it is ready to be crosscut into desired lengths.

Depending on log size, it will be necessary to support the large end when cross cutting.

When processing multiple log grades, make sure each grade has a designated placement for easy identification during extraction operations.

MEASURING Inspect butt of tree and recut if needed.

When using the Find End function, length accuracy will be poor for the following reasons: • Tree is crooked • The butt is not cut square • Sensor is dirty • Tree is too small • Sensor gets a false signal from bark or debris • Sensor gets reflections if the head is too close to the ground or other objects For best results, use the saw to cut the butt square if accuracy is critical.

Avoid reversing when measuring; returning to the log end and starting again will give more accurate length measuring.

Observing the diameter readout and the length controller is essential before activating the chainsaw.

DOUBLE CUTS Double cuts allow the tree to fall freely and minimise butt damage. It is recommended that larger-diameter trees be double cut to prevent bar damage.

Two cuts, a front (or compression) cut and then a back (or release) cut, are advised for larger trees. Using the two-cut method means the top or tip of the cutting unit is not travelling over the direction of fall, which can cause damage if the tree moves forward and down.

Position the harvester to the front or the desired direction of tree fall. Make the front cut with no side or upward pressure. The cut should finish when it is square with the direction of fall. The back cut should be higher than the front cut. This will allow the tree to fall to the front-cut level and avoid splitting wood towards the cutting unit.

According to the lean and size of tree, a slight side and upward pressure should be applied to the tree as it is being cut.

The aligning of the two cuts is important as there may be holding wood left on either side, which may cause damage to the saw unit if they are not parallel. Overcutting the back cut with the front cut can also stop the cutting unit from returning if the tree begins to fall.

QUARTER CUTS This method is used on various occasions to gain better control when felling. Use a saw cut placed at the base of the tree in the direction of fall approximately a quarter of the diameter into the tree. The head is then moved to the back of the tree ready for felling.

Calibration checks should be carried out at regular intervals if measuring equipment is being used.

WARNING Do not overcut the tree. Always work on one tree at the time and do not leave trees quarter-cut.

Ensure the back cut is placed higher in the tree than the quarter cut– approximately a quarter of the tree diameter.

When placing these cuts ensure both cuts are parallel to ensure a hinge affect is achieved otherwise loss of control will result.

2.20

Tigercat TH568 Harvesting Head

Controls and Operation

In some cases several quarter cuts will prevent the tree snapping off too soon. This method is used on large butt flares, heavy leaners, badly swept butts, multi leaders, and any other situation that requires more operator control in the felling procedure to prevent damaging the tree or machine.

FELLING ON HILLSIDES Felling trees on hillsides may expose the saw to dirt and debris on the uphill side of trees.

FELLING MULTI LEADERS

When felling on hilly terrain, ensure the harvester is positioned correctly and not allowing the bar tip to enter the ground on the uphill side of the tree.

Crutched trees can be cut either at a point where both separate, or if one side is of small diameter, it can be lifted until the crutch splits.

Felling direction should be up-slope or across the slope.

Avoid felling downslope as loss of control and head damage may occur.

Crutched trees at the base may need to be felled separately if the split line is close to the ground.

1

Carefully assess the situation and identify whether the tree is sound at the base, in which case the possibility of felling complete could be considered.

Signs of rot (1) identify the need to remove each leader individually. This is done in a conventional manner except at a greater height.

WARNING Caution must be exercised to ensure leaders do not break away unexpectedly. When cutting leaders, ensure the saw is not pinched between them.

• Always have a fire extinguisher at hand.

FIRE PREVENTION 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 once 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 and hydraulic hoses are properly restrained and clamped to prevent damage from chaffing.

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

For additional information, refer to FIRE PREVENTION on page 1.25.

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 onto 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.
