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.
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 (if equipped) 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 operator cab, 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 which has glow plugs. These starting aids can cause explosion and injure
you or bystanders.
• Always clean the machine, disconnect the battery, and disconnect the wiring from the electronic controllers 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.
• Use the procedure in the Operation & Maintenance Manual for cleaning the spark arrestor muffler (if equipped).
• Know where fire extinguishers and first aid kits are located and how to use them. Fire extinguishers are available from your
Bobcat dealer.
