SAFETY INSTRUCTIONS (Cont’d)

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 for Melroe Safety equipment.

Know where fire extinguisher and first aid kit 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 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.

Follow any environmental safety regulations when disposing of used fluids such as engine oil, grease or anti–freeze.

Do not use ether or starting fluids on engines which have 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 or Service Manuals for connecting the battery.

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