SAFETY INSTRUCTIONS (CONT’D) Fire Prevention The machines and some attachments have components that are at high temperatures 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.

Use the procedure in the Operation & Maintenance Manual for cleaning the spark arrestor muffler (if equipped).

Figure 1

Flammable debris (leaves, straw, etc.) must be removed regularly. If flammable debris is allowed to accumulate, it can cause a fire hazard. Clean often to avoid this accumulation. Flammable debris in the engine compartment is a potential fire hazard.

The spark arrestor 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 machine 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 hazards 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 any engine that has glow plugs. These starting aids can cause explosion and injure you or bystanders.

•

Always clean the machine and disconnect the battery before welding. Cover rubber hoses, battery and all other flammable parts. Keep a fire extinguisher near the machine 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 and for jump starting.

•

Know where fire extinguishers and first aid kits are located and how to use them. Fire extinguishers are available from your Bobcat dealer [Figure 1].

ATTACHMENTS AND BUCKETS

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.

NOTE: Warranty is void if non-approved attachments are used on the Bobcat mini loader.

WARNING

WARNING

Never use attachments or buckets that are not approved by Bobcat. Buckets and attachments for safe loads of specified densities are approved for each model. Unapproved attachments can cause injury or death.

AVOID INJURY OR DEATH Do not exceed Rated Operating Capacity (ROC).

Excessive load can cause tipping or loss of control.

W-2053-0887

W-2052-1285

Pallet Forks The dealer can identify, for each model mini loader, the attachments and buckets approved by Bobcat. The buckets and attachments are approved for Rated Operating Capacity and for secure fastening to the mini loader.

Figure OI-29 1

The Rated Operating Capacity for this loader is shown on a decal on the machine.

(See LOADER SPECIFICATIONS (MT52) on Page SPEC-3) The Rated Operating Capacity (ROC) is determined by using a standard dirt bucket, and material of normal density, such as dirt or dry gravel. If longer buckets are used, the load center moves forward and reduces the ROC. If very dense material is loaded, the volume must be reduced to prevent overloading.

Figure OI-28 B-17255

WRONG

If a pallet fork attachment is used, the load center moves forward and reduces the load capacity.

The maximum load to be carried when using a pallet fork is shown on a decal located on the pallet fork frame (Item 1) [Figure OI-29].

See your Bobcat Dealer for more information about pallet fork inspection, maintenance and replacement. See your Bobcat Dealer for load capacity when using a pallet fork and for other available attachments.

B-23048

Exceeding the Rated Operating Capacity [Figure OI-28] can cause the following problems: •

Difficult steering.

•

Faster track wear.

•

Loss of stability.

•

Reduced mini loader life.

IMPORTANT This mini 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.

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.
