PRECAUTIONS TO PREVENT FIRE

Fire caused by fuel, oil, coolant or window washer fluid

Do not bring any open flame close to fuel, oil, coolant or win-
dow washer fluid. Always observe the following.

• Do not smoke or use any open flame near fuel or other

flammable substances.

• Shut down the engine before adding fuel.
• Do not leave the machine when adding fuel or oil.
• Tighten all the fuel and oil caps securely.
• Be careful not to spill fuel on overheated surfaces or on

parts of the electrical system.

• After adding fuel or oil, wipe up any spilled fuel or oil.
• Put greasy rags and other flammable materials into a safe

container to maintain safety at the workplace.

• When washing parts with oil, use a non-flammable oil. Do

not use diesel oil or gasoline.There is danger that they
may catch fire.

• Do not weld or use a cutting torch to cut any pipes or tubes

that contain flammable liquids.

• Determine well-ventilated areas for storing oil and fuel.

Keep the oil and fuel in the specified place and do not al-
low unauthorized persons to enter.

• When performing grinding or welding work on the machine, move any flammable materials to a safe place

before starting.

Fire caused by accumulation or attachment of flammable material

• Remove any dry leaves, chips, pieces of paper, coal dust, or any other flammable materials accumulated or

attached to or around the engine exhaust manifold, muffler, or battery, or on the undercovers.

• To prevent fires from being caught, remove any flammable materials such as dry leaves, chips, pieces of

paper, coal dust, or any other flammable materials accumulated around the cooling system (radiator, oil
cooler) or on the undercover.

Fire coming from electric wiring

Short circuits in the electrical system can cause fire. Always observe the following.

• Keep all the electric wiring connections clean and securely tightened.
• Check the wiring every day for looseness or damage. Reconnect any loose connectors or refasten wiring

clamps. Repair or replace any damaged wiring.

Fire caused by piping

Check that all the clamps for the hoses and tubes, guards, and cushions are securely fixed in position.
If they are loose, they may vibrate during operation and rub against other parts.There is danger that this may
lead to damage to the hoses and cause high-pressure oil to spurt out, leading to fire and serious personal injury
or death.

Fire around the machine due to highly heated exhaust gas

Some models and specifications may be equipped with KDPF (Komatsu Diesel Particulate Filter).
KDPF is a system for purifying exhaust gas by removing soot in exhaust gas. In the process of purification (re-
generation), the temperature of discharged exhaust gas may be higher than that of conventional models. Do not
bring any flammable materials close to exhaust pipe outlet.
