440B 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 & 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 must stay with the machine when it is sold.

Replacement Operation & 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 & 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 English edition or a combination English, French, German, Italian, Dutch & Spanish edition.

• 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 dealer. This course is intended to provide rules and practices for correct operation of the Bobcat loader. The course is available in English and Spanish version.

• 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.

SAFE OPERATION NEEDS A QUALIFIED OPERATOR* A QUALIFIED OPERATOR MUST DO THE FOLLOWING:

• UNDERSTAND THE WRITTEN INSTRUCTIONS, RULES AND REGULATIONS • The written instructions from Melroe Company include the delivery report, Operation & Maintenance Manual and plastic handbook, EMI Safety Manual (available in Spanish) and machine signs (decals).

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

Regulations may identify a hazard such as a utility supply line.

• HAVE TRAINING WITH ACTUAL OPERATION • Operator training must consist of a demonstration 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.

• 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. For example, in handling certain loose material with a given bucket, he must know whether he can safely take a full load, or only part of a bucket load.

• The operator must know any prohibited uses or work areas, for example, he needs to know about excessive slopes.

• Wear tight fitting clothing. Always wear safety glasses when maintaining or servicing loader. Safety glasses, hearing protection or loader special applications kit are required for some work. See your dealer about Melroe Safety equipment.

* For an operator be qualified, he must not use drugs or alcoholic drinks which impair his alertness or coordination while working. An operator who is taking prescription drugs must get medical advice to determine if he can safely operate a machine.

440B 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 spark arrestor muffler 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.

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

• 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 near 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 glow plugs. 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. (See Page 27.)

• Use the procedure in the Operation & Maintenance Manual for cleaning the spark arrestor muffler. (See Page 31.)

A fire extinguisher is available from your local dealer.

HYDRAULIC/HYDROSTATIC SYSTEM

A

The hydraulic/hydrostatic systems use the same hydraulic fluid reservoir. Use only recommended fluid in the system. (See Specifications, Page 49.)

The hydrostatic pumps are driven by a belt from the engine. The hydraulic pump supplies fluid to the lift and tilt hydraulics.

Fluid also goes from the control valve to the port block to the hydrostatic pumps to provide charge pressure and cooling.

A hydraulic filter element is located at the right side of the loader under the operator cab. This filter is used to clean the fluid in the hydraulic/hydrostatic systems.

Checking/Adding Fluid to the Reservoir Put the Bobcat loader on a level surface. Lower the lift arms and tilt the bucket fully backward.

B–9082

Open the rear door. Remove the dipstick from the reservoir fill tube [A].

B

The fluid level is correct if the fluid level is between the marks on the dipstick.

NOTE: The dipstick may indicate an incorrect level of fluid when first removed because of expansion or contraction of oil in the fill tube.

Always (1) remove the dipstick, (2) wipe the dipstick, (3) insert the dipstick again and (4) re–check the fluid level.

If the fluid level is not at the top mark, add the correct fluid to the reservoir until the level is correct.

B–9081

Diesel fuel or hydraulic fluid under pressure can penetrate skin or eyes causing serious injury. Fluid leaks under pressure may not be visible. Use a piece of cardboard or wood to find leaks. Do not use your bare hand. Wear safety goggles. If fluid enters skin or eyes, get immediate medical attention.

SPARK ARRESTOR MUFFLER

A

Do not operate the loader with a defective exhaust system.

This loader is factory equipped with a U.S.D.A. Forestry Service approved spark arrestor muffler. It is necessary to do maintenance on this spark arrestor muffler to keep it in working condition. The spark arrestor muffler must be serviced by dumping the spark chamber every 100 hours of operation.

B–9055

If this machine is operated on flammable forest, brush or grass covered land, it must be equipped with a spark arrestor attached to the exhaust system and maintained in working order. Failure to do so will be in violation of California State Law, Section 4442 PRC. Make reference to local laws and regulations for spark arrestor requirements.

I–2022–1285

Stop engine and allow the muffler to cool before cleaning the spark chamber. Wear safety goggles. Failure to obey can cause serious injury.

Cleaning the Spark Arrestor Muffler Stop the engine and open the rear door.

Chaincase Fluid Level Put the loader on a level surface.

Remove the plug at the front of the chaincase [A]. If the fluid can be reached with the tip of the finger through the hole the level is correct.

Add fluid through the check plug hole until the fluid flows from the hole. Tighten the plug.

TIRE MAINTENANCE Check the tires regularly for wear, damage and correct pressure.

B–9066

B

Tire Rotation Front tires usually wear faster than rear tires. To keep tire wear even, rotate the tires as shown [B].

Tires must be the same size and pressure for best handling of the loader. If the tires are worn different amounts, loader durability is improved by matching pairs of tires on each side of the loader.

Tire Installation on Rim When installing a tire on a rim, avoid excess pressure which can rupture the tire and cause serious personal injury. During inflation of the tire, check the tire pressure frequently to avoid over inflation.

The rim flange must be clean and free of rust. The tire bead and rim flange must be lubricated with a rubber lubricant before mounting the tire to avoid damage to the tire or rim.

C–1965

Tire Pressure Recommended tire pressure must be maintained to avoid excessive tire wear and loss of stability and handling.

The tires may be inflated above or below operating pressure for shipping. Check for correct pressure before operating the loader. The correct tire pressure is 40 PSI (276 kPa).

Wheel Nuts See the Service Schedule Page 19 for the service intervals to check the wheel nuts. Correct torque is 40–45 ft.–lbs. (54–61 Nm).
