WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints such as eczema. Strict hygiene should always be observed.

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

Some advice which should be observed:

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

• Oils used in this machine may be hot enough to cause serious burns.

• Avoid contact with oil, particularly heated oil.

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

• Oil on the skin should be washed off immediately with soap and water.

• Wear protective gloves. Hands should be clean before putting on gloves. Apply protective cream to the hands to make washing easier.

• 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!

• DO NOT put oily rags in your pockets.

• Determine the material composition of any seals or gaskets, If fluoroelastomer 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.

• Oil soiled clothing should be changed as soon as possible.

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

• Avoid breathing in oil fumes.

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

• 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.

• Cuts and abrasions must be attended to immediately. Clean them and apply first-aid.

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

Safety

Tigercat Mulching Head

URBAN PRECAUTIONS

AVOID FENCES • DO NOT drive the mulcher into fences, especially chain link fences. Chain link fencing can damage the rotor. Refer to AVOID METAL AND WIRE in THIS SECTION.

Increased safety precautions are required when working: • Near streets.

• Near highways.

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

• In parks, on golf courses or other inhabited areas.

• Near buildings.

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

ESTABLISH SAFETY PARAMETERS THAT FIT THE SITE • String coloured warning tape to cordon off the area.

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

• Erect barriers.

ASSESSING THE POTENTIAL DANGERS OF THE JOB SITE Before working in a new area a visual survey of the area to be worked is helpful in identifying undesirable materials which may be present. Remove as much of the undesirable materials as is practical before proceeding.

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

• Work within your operating skills. DO NOT attempt to cut down a tree that is too large to handle.

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

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

AVOID METAL AND WIRE • Metal can break rotor teeth and create a projectile hazard.

• Never use this machine to clear an area when other equipment and operator's are also moving in.

Preplan to work the area in advance before other equipment arrives.

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

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

USE CAUTION WITH STRINGY VEGETATION Shredding materials like Palmetto, Bird of Paradise, and yard waste tied with plastic should be approached with caution. Stringy vegetation and plastic ties gravitate toward the bearings. The operator should exercise caution while working with this type of material.

• Stop the mulching head rotor before leaving the mulching area.

NOTE: The rotor may continue to free wheel for several minutes after the rotor switch has been turned OFF.

AVOID PLASTICS

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

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

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

• Inspect the rotor for clinging strands often.

ANIMAL REMAINS Animal remains such as calf and deer carcasses will plug the machine due to their leathery skin. Avoid the unpleasant task of removing the remains from the rotor.

FLUID INJECTION INJURY

Safety SEARCHING FOR POSSIBLE FLUID LEAKS WARNING

WARNING Diesel fuel or hydraulic fluid under pressure can penetrate the skin and could result in serious injury or death. 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.

Never search for leaks with your bare hands.

Always wear thick protective gloves.

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.

• Be sure to wear safety goggles for eye protection.

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

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

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

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.

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

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

• 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 • Turn OFF the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

IN THE EVENT OF ANY SUSPECTED FLUID INJECTION INJURY

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

• Hoses must always be rated for the pressures to which they will be subjected.

• Report the injury to your supervisor immediately.

• Seek professional medical attention immediately.

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

The best defence against suffering the effects of fluid injection is to prevent the accident from occurring.

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 • 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.

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

• Wear proper protective equipment 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.

• Protective shrouds must be installed on all grease gun nozzles as safety devices.

• Remove dirt and grease from the grease fittings prior to greasing.

• Replace any defective grease fittings 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.

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

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.

• 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.

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.

• 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.

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.

• 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, always 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.

1.19

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.

Tigercat Mulching Head 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.

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

• 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.

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.

• 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.

IF YOU ARE CAUGHT OUTSIDE AND HAVE NOWHERE TO GO: • Avoid wide-open areas where you project above the surrounding landscape.

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.

• 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.

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

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

IF YOU CAN, GET INSIDE: 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 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 well away from corded telephones, electrical appliances, lighting fixtures, radio microphones, electrical sockets and plumbing pipes and fixtures.

• 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.

1.20

Tigercat Mulching Head

Safety

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.

FIRE PREVENTION

• 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.

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.

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: • 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 CLEANING COOLER PACKAGE in SECTION 2.

• 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.

• 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 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. 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.

• 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.

• 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 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.

• 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.

1.22

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

Safety WHAT TO DO TO PREPARE FOR A MACHINE FIRE • Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and always well maintained.

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

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

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

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

• 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.

• Make sure the nozzle of any hand held extinguisher and pressurized water system available on the machine and at the work site fits within the fire extinguisher access holes in the doors of the machine.

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

• Ensure that your fire detection system* is in working order. Refer to FIRE DETECTION SYSTEM in SECTION 2.

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

• Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2.

• DO NOT use the machine on top of or to push piles of burning timber. A machine fire will most probably result.

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

NOTICE

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

Equipment fires adversely effect your ability to log, may increase your insurance premiums dramatically or prevent you from obtaining insurance coverage at all.

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

1.23

Safety

Tigercat Mulching Head

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

5. Be aware that, hoses containing engine coolant, diesel fuel or hydraulic hoses could fail during a fire.

If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

• 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.

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

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

• Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system** on your machine. There is not enough time available to read instructions during a fire emergency.

• Use the PASS method. This is the most effective use of a fire extinguisher.

• Pull the pin at the top of the extinguisher that keeps the handle from being pressed. Break the plastic seal as the pin is pulled.

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

• Aim the nozzle at the base of the fire. DO NOT aim the nozzle at the flames. In order to put out the fire, you must extinguish the fuel, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

WHAT TO DO WHEN A MACHINE FIRE OCCURS If operating the machine when a fire occurs:

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

1. Lower all working attachments to the ground.

2. Turn OFF the engine.

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

3. Activate the fire suppression system**.

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

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

6. At all times ensure your own personal safety and the safety of anyone that may be in the area. Approach any fire with extreme caution. All fires can be very dangerous and life threatening.

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

Before deciding to fight the fire, be certain that: 1. The fire is small and not rapidly spreading.

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

700068

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

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

TYPICAL FIRE EXTINGUISHER ACCESS HOLE • Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

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

1.24

Tigercat Mulching Head

Safety

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

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

• 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.

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

• Remain with the machine until help arrives.

WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED • Before returning the machine to work:

• In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic.

• Make sure the cause of the fire is determined and all appropriate repairs are completed.

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

NOTE: All surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

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

To neutralize the acidic paste on large surfaces, spray or wash 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. Cleaning of electrical contacts should be done using an electrical contact cleaner that has no flash or fire point and is non-corrosive and non-conductive such as CRC Contact Cleaner 2000.

• Notify your equipment dealer and/or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101. *NOTE: Fire detection systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine. **NOTE: Dry chemical fire suppression systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

• In areas exposed to heat during the fire, the dry chemical powder will melt forming a coating that cakes or crusts on all surfaces. To break down the caked dry chemical, spray or wash these areas with a 50/50 mixture of hot water and isopropyl alcohol.

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

DRY CHEMICAL CLEANUP PROCEDURES Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability.

These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

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

Service and Maintenance

PREVENTIVE MAINTENANCE SCHEDULE

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

NEW MULCHING HEAD MAINTENANCE

1. Pine needles and bark when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

INITIAL PRE-DELIVERY INSPECTION Perform the initial pre-delivery inspection using Tigercat form numbers 5338 and 5347: PDI and 125 hour inspection report

FIRST 125 HOUR INSPECTION AND SERVICE REPORT

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.

With the owner's mechanic present, perform an inspection and service according to the Tigercat form numbers 5338 and 5347: PDI and 125 hour inspection report.

3. In case of fire lower the boom system to the ground and shut off the engine before discharging the fire suppression system (if machine is equipped).

This must be completed within the first 125 hour time frame.

NOTE: The mulching head has no provisions that can be connected to a fire suppression system.

IMPORTANT! To qualify for continued warranty, this report must be completed and returned to Tigercat Industries Inc. Warranty department.

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

NOTE: Use of filters other than genuine Tigercat replacement filters is not recommended.

TIGHTENING POINTS All hydraulic connections Hose clamps All cylinder and boom pin retainers Motor mounting bolts Drive belt tensioner Any other loose nut, bolt or fitting

HOUR METER – MAINTENANCE Check the machine hour meter on a regular basis to determine the scheduled maintenance times for the mulching head.

The intervals and times on the scheduled maintenance chart in this manual are for normal operating conditions.

If the mulching head is being operated in difficult or severe conditions, use shorter service intervals.

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.
