873 Bobcat Loader Operation & Maintenance Manual

SAFETY INSTRUCTIONS SAFETY IS THE OPERATOR’S RESPONSIBILITY The Skid Steer Loader is a highly maneuverable and compact machine. In operation, it is rugged and useful under a wide variety of conditions. This presents an operator with hazards associated with off highway, rough terrain applications. The loader has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill or cause illness so the loader must be used with adequate ventilation. The loader has a spark arrestor muffler which is required for operation in certain areas.

The dealer explains the capabilities and restrictions of the loader and attachments for each application. The dealer demonstrates the safe operation of the loader according to Melroe’s instructional materials; which are also available to operators. The dealer can also identify unsafe modifications or use of unapproved attachments. The attachments and buckets are designed for rated capacity and secure fastening to the loader. The user must check with the dealer, or Melroe Company literature, to determine safe loads of materials of specified densities for his loader–attachment combination.

The following publications provide information on the safe use and maintenance of the loader and attachments: • The Delivery Report is used to assure that complete instructions have been given to the new owner and that the machine is in safe operating condition.

• The Operation and Maintenance Manual delivered with the loader gives operating information as well as routine maintenance and service procedures. It is a part of the loader and can be stored in a container (later models) provided inside the cab. Replacement Operation and Maintenance Manuals can be ordered from your Bobcat loader dealer.

• The loader has machine signs (decals) which instruct on the safe operation and care. The signs and their locations are shown in the Operation and Maintenance Manual. Replacement signs are available from your Bobcat loader dealer.

• The loader has a plastic Operator’s Handbook fastened to the operator cab. Its brief instructions are convenient to the operator. The Handbook is available from your dealer in an English edition or one of many other languages. See your Bobcat dealer for more information on translated versions.

• The EMI Safety Manual (available in Spanish) delivered with the loader gives general safety information.

• The Service Manual and Parts Manual are available from your dealer for use by mechanics to do shop–type service and repair work.

• The Skid–Steer Loader Operator Training Course is available through your local Bobcat dealer. This course provides information for safe and efficient operation of the Bobcat loader. The course is available in English and Spanish versions.

• The Bobcat Skid–Steer Loader Safety Video is available from your Bobcat Dealer.

The dealer and owner/operator review the recommended uses of the loader and attachments when the loader is delivered.

If the owner/operator will be using the loader for a different application(s) he must ask the dealer for recommendations on the new use.

Call Before You Dig 1–888–258–0808 When you call, you will be directed to a location in your state/city for information about burried lines (telephone, cable TV, water, sewer, gas,etc.).

• Check the rules and regulations at your location. The rules may include an employer’s work safety requirements.

Regulations may apply to local driving requirements or use of Slow Moving Vehicle emblem. Regulations may identify a hazard such as a utility line.

• HAVE TRAINING WITH ACTUAL OPERATION • Operator training must consist of a demostration and verbal instruction. This training is given by your dealer before the loader is delivered.

• The new operator must start in an area without bystanders and use all the controls until he can operate the loader safely under all conditions of the work area. Always fasten seat belt and lower seat bar before operating.

• The Skid Steer Loader Operator Training Course is available in English and Spanish. The course provides information for safe and efficient operation. See your dealer for availability.

• KNOW THE WORK CONDITIONS • For each material to be handled, the operator must know how to avoid exceeding the rated operating capacity of the loader.

873 Bobcat Loader Operation & Maintenance Manual

FIRE PREVENTION The loader has several components that are at high temperature under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcs or sparks.

Flammable debris (leaves, straw, etc.) must be removed regularly. If flammable debris is allowed to accumulate, it will increase the fire hazard. The loader must be cleaned as often as necessary to avoid this accumulation. Flammable debris in the engine compartment is a fire hazard when the loader is parked with a hot engine.

The exhaust system is designed to control the emission of hot particles from the engine and exhaust system, but the muffler and the exhaust gases are still hot.

• Do not use the Bobcat loader where exhaust, arcs, sparks or hot components can contact flammable material, explosive dust or gases.

• The engine compartment and engine cooling system must be inspected every day and cleaned if necessary to prevent fire hazard and overheating.

• Check all electrical wiring and connections for damage. Keep the battery terminals clean and tight. Repair or replace any damaged part.

• Check fuel and hydraulic tubes, hoses and fittings for damage and leakage. Never use open flame or bare skin to check for leaks. Tighten or replace any parts that show leakage. Always clean fluid spills. Do not use gasoline or diesel fuel for cleaning parts. Use commercial nonflammable solvents.

• Do not use ether or starting fluids on this engine. It has a glow plug. These starting aids can cause explosion and injure you or bystanders.

• Always clean the loader and disconnect the battery before doing any welding. Cover rubber hoses, battery and all other flammable parts. Keep a fire extinguisher near the loader when welding. Have good ventilation when grinding or welding painted parts. Wear dust mask when grinding painted parts. Toxic dust or gas can be produced.

• Stop the engine and let it cool before adding fuel. No smoking!

• Use the procedure in the Operation & Maintenance Manual for connecting the battery.

• Use the procedure in the Operation & Maintenance Manual for cleaning the spark arrestor muffler.

• Know where fire extinguishers and first aid kits are located and how to use them.

A fire extinguisher is available from your local dealer. The fire extinguisher can be installed in the location shown [A].

ATTACHMENTS AND BUCKETS

A

WRONG

Never use attachments or buckets which are not approved by Melroe Company. Buckets and attachments for safe loads of specified densities are approved for each model.

Unapproved attachments can cause injury or death.

W–2052–1285 B–06587

The dealer can identify, for each model loader, the attachments and buckets approved by Melroe Company.

The buckets and attachments are approved for rated operating capacity and for secure fastening to the Bob–Tach.

The rated operating capacity for this loader is shown on a decal in the operator cab. (See SPECIFICATIONS Page 91.)

The rated operating capacity is determined by using a standard dirt bucket, and material of normal density, such as dirt or dry gravel. If longer buckets are used and load center moves forward it reduces the rated operating capacity. If very dense material is loaded, the volume must be reduced.

AVOID INJURY OR DEATH Do not exceed rated operating capacity.

Excessive load can cause tipping or loss of control.

W–2053–0887

Exceeding the rated operating capacity [A] can cause the following problems: 1. Steering the loader may be difficult.

B

2. Tires may wear faster.

WEIGHT OF LOADS LBS. (KG) (Without counterweights)

1680(760)

4. The life of the Bobcat loader will be reduced.

Use the correct size bucket for the type and density of material being handled. For safe handling of materials and avoiding machine damage, the attachment (or bucket) should handle a full load without going over the rated operating capacity for the loader. Partial loads make steering more difficult.

Maximum load to be carried when using a pallet fork is shown in figure [B]. See your Bobcat loader dealer for more information about pallet forks and other available attachments.

P–10142

B

Inflate tires to the MAXIMUM pressure shown on the sidewall of the tire. DO NOT mix brands of tires used on the same loader.

I–2057–0794

Rear tires usually wear faster than front tires. To keep tire wear even, move the front tires to the rear and rear tires to the front [B].

It is important to keep the same size tires on each side of the loader. If different sizes are used, each tire will be turning at a different rate and cause excessive wear. The tread bars of all the tires must face the same direction.

B–09976

Recommended tire pressure must be maintained to avoid excessive tire wear and loss of stability and handling capability. Check for the correct pressure before operating the loader.

Tire Mounting Tires are to be repaired only by an authorized person using the proper procedures and safety equipment. Tires and rims must always be checked for correct size before mounting. Check rim and tire bead for damage.

Do not inflate tires above specified pressure.

Failure to use correct tire mounting procedure can cause an explosion which can result in injury or death.

W–2078–1285

The rim flange must be cleaned and free of rust. The tire bead and rim flange must be lubricated with a rubber lubricant before mounting the tire, avoid excessive pressure which can rupture the tire and cause serious injury or death. During inflation of the tire, check the tire pressure frequently to avoid over inflation.
