Literature Information

This manual should be stored in the operator's compartment in the literature holder or seat back literature storage area.

This manual contains safety information, operation instructions, transportation information, lubrication information and maintenance information.

Some photographs or illustrations in this publication show details or attachments that can be different

from your machine. Guards and covers might have been removed for illustrative purposes.

Continuing improvement and advancement of product design might have caused changes to your machine which are not included in this publication. Read, study and keep this manual with the machine.

Whenever a question arises regarding your machine, or this publication, please consult your Cat dealer for the latest available information.

Safety

The safety section lists basic safety precautions. In addition, this section identifies the text and locations

of warning signs and labels used on the machine.

Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and repair on this machine.

Operation

The operation section is a reference for the new operator and a refresher for the experienced operator. This section includes a discussion of gauges, switches, machine controls, attachment controls, transportation and towing information.

Maintenance Intervals

Use the service hour meter to determine servicing intervals. Calendar intervals shown (daily, weekly, monthly, etc.) can be used instead of service hour meter intervals if they provide more convenient servicing schedules and approximate the indicated service hour meter reading. Recommended service should always be performed at the interval that occurs first.

Under extremely severe, dusty or wet operating conditions, more frequent lubrication than is specified in the maintenance intervals chart might be

necessary.

Perform service on items at multiples of the original requirement. For example, at every 500 service hours or 3 months, also service those items listed

under every 250 service hours or monthly and every 10 service hours or daily.

California Proposition 65 Warning

Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer,

birth defects, and other reproductive harm.

Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands

after handling.

Certified Engine Maintenance

Proper maintenance and repair is essential to keep the engine and machine systems operating correctly. As the heavy duty off-road diesel engine owner, you are responsible for the performance of the required maintenance listed in the Owner Manual, Operation and Maintenance Manual, and Service Manual.

Photographs and illustrations guide the operator through correct procedures of checking, starting, operating and stopping the machine.

Operating techniques outlined in this publication are basic. Skill and techniques develop as the operator gains knowledge of the machine and its capabilities.

Maintenance

The maintenance section is a guide to equipment care. The Maintenance Interval Schedule (MIS) lists the items to be maintained at a specific service interval. Items without specific intervals are listed under the "When Required" service interval. The Maintenance Interval Schedule lists the page number for the step-by-step instructions required to accomplish the scheduled maintenance. Use the Maintenance Interval Schedule as an index or "one

safe source" for all maintenance procedures.

Cat Product Identification Number

Effective First Quarter 2001 the Cat Product Identification Number (PIN) has changed from 8 to 17

characters. In an effort to provide uniform equipment identification, Caterpillar and other construction equipment manufacturers are moving to comply with the latest version of the product identification numbering standard. Non-road machine PINs are defined by ISO 10261. The new PIN format will apply to all Cat machines and generator sets. The PIN plates and frame marking will display the 17 character PIN. The new format will look like the

following:

Machines and generator sets produced before First Quarter 2001 will maintain their 8 character PIN

format.

Components such as engines, transmissions, axles, etc. and work tools will continue to use an 8 character

Serial Number (S/N).

Safety Section

General Hazard Information

When maintenance is performed above ground level, use appropriate devices such as ladders or man lift machines. If Equipped, use the machine anchorage points and use approved fall arrest harnesses and lanyards.

Pressure Air and Water

Pressurized air and/or water can cause debris and/or hot water to be blown out. The debris and/or hot water could result in personal injury.

When pressurized air and/or pressurized water is used for cleaning, wear protective clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield.

The maximum air pressure for cleaning purposes must be reduced to 448 kPa (65 psi) when the nozzle is deadheaded and the nozzle is used with an

effective chip deflector and personal protective equipment. The maximum water pressure for cleaning purposes must be below 448n kPa (65 psi).

Make sure that all protective guards and all covers are secured in place on the equipment.

Keep the equipment free from foreign material. Remove debris, oil, tools, and other items from the

deck, from walkways, and from steps.

Secure all loose items such as lunch boxes, tools, and other items that are not a part of the equipment.

Know the appropriate work site hand signals and the personnel that are authorized to give the hand signals. Accept hand signals from one person only.

Do not smoke when you service an air conditioner. Also, do not smoke if refrigerant gas may be present. Inhaling the fumes that are released from a flame that contacts air conditioner refrigerant can cause bodily harm or death. Inhaling gas from air conditioner refrigerant through a lighted cigarette can cause bodily harm or death.

Never put maintenance fluids into glass containers. Drain all liquids into a suitable container.

Obey all local regulations for the disposal of liquids.

Use all cleaning solutions with care. Report all necessary repairs.

Avoid direct spraying of water on electrical connectors, connections, and components. When using air for cleaning, allow the machine to cool to reduce the possibility of fine debris igniting when redeposited on hot surfaces.

Trapped Pressure

Pressure can be trapped in a hydraulic system. Accumulators in a hydraulic system will store pressure. Allow a sufficient amount of time for the pressure that is stored in the accumulators to be released. Releasing trapped pressure can cause sudden machine movement or attachment

movement. Use caution if you disconnect hydraulic lines or fittings. High-pressure oil that is released can cause a hose to whip. High-pressure oil that is released can cause oil to spray. Fluid penetration can cause serious injury and possible death.

Fluid Penetration

Pressure can be trapped in the hydraulic circuit long after the engine has been stopped. The pressure can cause hydraulic fluid or items such as pipe plugs to escape rapidly if the pressure is not relieved correctly.

Do not allow unauthorized personnel on the equipment.

Unless you are instructed otherwise, perform maintenance with the equipment in the servicing position. Refer to Operation and Maintenance Manual for the procedure for placing the equipment in the servicing position.

Do not remove any hydraulic components or parts until pressure has been relieved or personal injury may occur.

Tire Information

SMCS Code: 7000

Explosions of air inflated tires have resulted from heat-induced gas combustion inside the tires. Explosions can be caused by heat that is generated by welding, by heating rim components, by external fire, or by excessive use of brakes.

A tire explosion is much more violent than a blowout. The explosion can propel the tire, the rim components, and the axle components from the machine. Stay out of the trajectory path. Both the force of the explosion and the flying debris can cause property damage, personal injury, or death.

Illustration 88 g02643077

The recommended location for mounting the fire extinguisher is inside on the left-hand access door (1).

Make sure that a fire extinguisher is on the machine. Make sure that you are familiar with the operation of the fire extinguisher. Inspect the fire extinguisher and service the fire extinguisher regularly. Obey the recommendations on the instruction plate.

If the fire extinguisher is mounted on the ROPS, strap the mounting plate to a leg of the ROPS. If the weight of the fire extinguisher is more than 4.5 kg (10 lb), mount the fire extinguisher as low as possible on one leg. Do not mount the fire extinguisher on the upper one-third area of the leg.

Illustration 89 g02166933

Typical example of tire is shown

Do not approach a hot or an apparently damaged tire.

Prentice recommends against using water or calcium as a ballast for the tires except in machines designed for this additional mass. For those applicable machines, the maintenance section will contain

instructions on the correct tire inflation and filling procedures. Ballast, such as fluid in the tires, increases overall machine weight and may affect braking, steering, power train components, or the certification of the protective structure such as the ROPS. The use of tire/rim rust preventatives or other liquid additives is not required.

Dry nitrogen gas is recommended for inflation of tires. If the tires were originally inflated with air, nitrogen is still preferred for adjusting the pressure. Nitrogen mixes properly with air.

Page 48

Safety Section Electrical Storm Injury Prevention

SEBU9420-01

Nitrogen inflated tires reduce the potential of a tire explosion because nitrogen does not aid combustion. Nitrogen helps to prevent oxidation of the rubber, deterioration of rubber, and corrosion of rim

components.

To avoid overinflation, proper nitrogen inflation equipment and training in the usage of the equipment are necessary. A tire blowout or a rim failure can result from improper equipment or from misused equipment.

When you inflate a tire, stand behind the tread and use a self-attaching chuck.

Servicing tires and rims can be dangerous. Only trained personnel that use proper tools and proper procedures should perform this maintenance. If correct procedures are not used for servicing tires and rims, the assemblies could burst with explosive force. This explosive force can cause serious personal injury or death. Carefully obey the specific instructions from your tire dealer.

• Never intentionally let the disc hit a rock

• ONLY fell with the disc horizontal and the bunching head vertical. DO NOT cut with the feller buncher head tipped forward.

Operation in Rocky Terrain

Flying debris, falling trees, limbs, and tops can cause severe injury or death. Do not operate saw within 91 M (300 feet) of personnel or machinery.

Operating feller buncher in rocky conditions is hazardous and should be avoided. If felling in rocky conditions cannot be avoided the following precautions should be taken:

• Use only solid steel teeth. DO NOT use carbide tipped teeth.

• Make the cut high enough to clear the rocks.

NOTICE

Teeth breaking when hitting a rock can damage the tooth seat on the saw disc. The more economical option is to use a segmented disc. When broken tooth damages the tooth seat, replace tooth and the segment instead of a whole disc.

Dangerous Operation Practices

Do not use feller bunchers to harvest trees in a fallen or blown over condition. Serious personal

injury or death may result from high velocity projectiles being thrown through the cab window.

Feller bunchers are intended to fell standing trees, not for harvesting fallen or blown over trees.

Do not use feller buncher to cut when the head and saw disc are tilted forward from the cab more than 20 degrees. Such use may result in high velocity

projectiles, like wood pieces, being thrown with enough force to penetrate cab window. Projectiles penetrating the cab windows or entering the cab can cause serious personal injury or death.

Slope Operation

SMCS Code: 7000; 7615

Machines that are operating safely in various applications depend on these criteria: the machine model, configuration, machine maintenance, operating speed of the machine, conditions of the terrain, fluid levels and tire inflation pressures. The most important criteria are the skill and judgment of the operator.

A trained operator that follows the instructions in the Operation and Maintenance Manual has the greatest impact on stability. Operator training provides a person with the following abilities: observation of working and environmental conditions, feel for the machine, identification of potential hazards and operating the machine safely by making appropriate decisions.

When you work on side hills and when you work on slopes, consider the following important points:

Page 52

Safety Section Equipment Lowering with Engine Stopped

SEBU9420-01

Note: Operation of this machine on slopes greater than 30% (16.7 deg) is not recommended. A 30% slope can be visualized by a .91 M (3 ft )rise in a 3 M (10 ft ) distance. Local slope conditions may dictate a lower safe slope than 30% (16.7 deg).

Speed of travel – At higher speeds, forces of inertia tend to make the machine less stable.

Roughness of terrain or surface – The machine may be less stable with uneven terrain.

Direction of travel – Avoid operating the machine across the slope. When possible, operate the machine up the slopes and operate the machine down the slopes. Place the heaviest end of the machine uphill when you are working on an incline.

Mounted equipment – Balance of the machine may be impeded by the following components: equipment that is mounted on the machine, machine

configuration, weights and counterweights.

Nature of surface – Ground that has been newly filled with earth may collapse from the weight of the machine.

Surface material – Rocks and moisture of the surface material may drastically affect the machine

traction and stability. Rocky surfaces may promote side slipping of the machine.

Slippage due to excessive loads – May cause downhill tracks or downhill tires to dig into the ground, which will increase the angle of the machine.

Width of tracks or tires – Narrower tracks or narrower tires further increase the digging into the

ground which causes the machine to be less stable.

Implements attached to the drawbar – May decrease the weight on the uphill tracks. May also decrease the weight on the uphill tires. The decreased weight will cause the machine to be less stable.

Height of the working load of the machine – When the working loads are in higher positions, the stability of the machine is reduced.

Operated equipment – Be aware of performance features of the equipment in operation and the effects on machine stability.

Operating techniques – Keep all attachments or pulled loads low to the ground for optimum stability.

Machine systems have limitations on slopes – Slopes can affect the proper function and operation of the various machine systems. These machine systems are needed for machine control.

Note: Safe operation on steep slopes may require special machine maintenance. Excellent skill of the operator and proper equipment for specific applications are also required. Consult the Operation and Maintenance Manual sections for the proper fluid level requirements and intended machine use.

Guards

(Operator Protection)

SMCS Code: 6700; 7000; 7150-MCH; 7150; 7325

There are different types of guards that are used to protect the operator. The machine and the machine application determine the type of guard that should be used.

A daily inspection of the guards is required in order to check for structures that are bent, cracked, or loose.

Never operate a machine with a damaged structure.

The operator becomes exposed to a hazardous situation if the machine is used improperly or if poor operating techniques are used. This situation can occur even though a machine is equipped with an appropriate protective guard. Follow the established operating procedures that are recommended for your machine.

Roll over Protective Structure (ROPS), Falling Object Protective Structure (FOPS) or Tip Over Protection Structure (TOPS)

The ROPS/FOPS Structure (if equipped) on your machine is designed, tested, and certified for that machine. Any alteration or any modification to the ROPS/FOPS Structure could weaken the structure.

Placing the operator into an unprotected environment. Modifications or attachments that

cause the machine to exceed the weight stamped on the certification plate also place the operator into an unprotected environment. Excessive weight may inhibit the brake performance, the steering performance, and the ROPS. The protection that is offered by the ROPS/FOPS Structure will be impaired if the ROPS/FOPS Structure has structural damage. Damage to the structure can be caused by an overturn, a falling object, a collision, etc.

The Tip Over Protection Structure (TOPS) is another type of guard that is used on mini hydraulic excavators. This structure protects the operator in the event of a tipover. The same guidelines for the inspection, the maintenance, and the modification of the ROPS/FOPS Structure are required for the Tip Over Protection Structure.

Other Guards (If Equipped)

Protection from flying objects and/or falling objects is required for special applications. Logging applications and demolition applications are two examples that require special protection.

A front guard is required when a work tool that creates flying objects is used. Front guards that are approved by Prentice or polycarbonate front guards that are approved by Prentice are available for machines with a cab or an open canopy. On machines that are equipped with cabs, the windows should also be closed. Safety glasses are recommended when flying hazards exist for machines with cabs and machines with open canopies.

If the work material extends above the cab, top guards and front guards should be used. Typical examples of this type of application are listed below:

• Demolition applications

• Rock quarries

• Forestry products

Additional guards may be required for specific applications or work tools. The Operation and Maintenance Manual for your machine or your work tool will provide specific requirements for the guards. Consult your Prentice dealer for additional information.

Do not mount items (fire extinguishers, first aid kits, work lights, etc.) by welding brackets to or by drilling holes in the ROPS/FOPS Structure. Welding brackets or drilling holes in the ROPS/FOPS Structures can weaken the structures. Consult your Prentice dealer for mounting guidelines.

Towing the Machine

SMCS Code: 7000

Personal injury or death could result when towing a disabled machine incorrectly.

Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.

To perform the towing procedure properly, use the following recommendations.

Use these towing instructions for moving a disabled machine over a short distance of 8 km (5 MI) or less. Do not move the machine faster than 3 km/h (2 mph) . Move the machine to a convenient location for

repair. Always haul the machine if long distance moving is required.

Shielding must be provided on the towing machine in order to protect the operator in case the tow line or the tow bar breaks.

Do not allow riders on a machine that is being towed unless the operator can control the steering and/or the braking of the towed machine.

It may be necessary to connect a larger machine or additional machines to the disabled machine in order

to provide sufficient control and sufficient braking. This procedure will prevent the disabled machine from rolling away out of control on a downgrade.

The requirements for all different situations cannot be specified. Minimal towing machine capacity is required on smooth, level surfaces. Maximum towing machine capacity is required on inclines or on poor surface conditions.

Any towed machine with a load must be equipped with a braking system that can be operated from the operator compartment.

Consult your Cat dealer for more information about towing a disabled machine.

Towing with a Running Engine

If the engine is running, the machine can be towed for a short distance under certain conditions. The

power train and the steering system must be operable. Tow the machine for a short distance only. For example, pull the machine out of mud or to the side of the road.

The operator on the towed machine must steer the machine in the direction of the tow line.

Carefully obey all of the instructions that are outlined in this topic.

Towing with a Stopped Engine

Before you tow the machine, inspect the tow line or the tow bar. Make sure that the tow line or the tow bar

is sturdy enough for towing the disabled machine. The tow line or tow bar must have a strength that is equal to 1.5 times the gross weight of the machine that is being towed.

Do not use a chain for pulling. A chain link may break. This procedure can cause personal injury. Use a wire rope that has cable loops or end rings. Position an observer at a safe location. The observer

should stop the pulling procedure if the cable starts to break or the cable starts to unravel. If the towing machine moves without the pulled machine, stop the pulling procedure.

Keep the tow line angle to a minimum. Do not exceed a 30 degree angle from the straight ahead position.

Quick machine movement could overload the tow line or the tow bar. This procedure could cause the tow

line or the tow bar to break. Gradual, smooth machine movement works better.

Normally, the towing machine should be as large as the disabled machine. The towing machine must have enough brake capacity, enough weight, and enough power for the grade and the distance that is involved.

Care must be taken to ensure that fluids are contained during performance of inspection, mainte-

nance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, “Dealer Service Tool Catalog” for tools and supplies suitable to collect and contain fluids on Cat

Dispose of all fluids according to local regulations and mandates.

Perform the following steps before you tow the machine.

1. Reverse the hydraulic steering hose connections on one cylinder only. This procedure will allow the steering cylinders to move freely.

Note: Make sure that the cylinder hoses are connected correctly before you operate the machine again. The steering system will not function if the hose connections are reversed.
