GENERAL PRECAUTIONS
FIRE PREVENTION
q Fire caused by fuel or oil
Fuel, oil, antifreeze, and window washer liquid are particu-
larly flammable and can be hazardous. To prevent fire,
always observe the following:
q Do not smoke or use any flame near fuel or oil.
q Stop the engine before refueling.
q Do not leave the machine while adding fuel or oil.
q Tighten all fuel and oil caps securely.
q Do not spill fuel on overheated surfaces or on parts of
the electrical system.
q Use well-ventilated areas for adding or storing oil and
fuel.
q Keep oil and fuel in the determined place and do not
allow unauthorized persons to enter.
q After adding fuel or oil, wipe up any spilled fuel or oil.
q When carrying out grinding or welding work on the
chassis, move any flammable materials to a safe place
before starting.
q When washing parts with oil, use a non-flammable oil.
Diesel oil and gasoline may catch fire, so do not use
them.
q Put greasy rags and other flammable materials into a
safe container to maintain safety at the work place.
q Do not weld or use a cutting torch to cut any pipes or
tubes that contain flammable liquids.
q Fire caused by accumulation of flammable material.
Remove any dry leaves, chips, pieces of paper, dust, or any other flammable materials accumulated or affixed
around the engine, exhaust manifold, muffler, or battery, or inside the undercovers.
q Fire coming from electric wiring
Short circuits in the electrical system can cause fire.
q Always keep electric wiring connections clean and securely tightened.
q Check the wiring every day for looseness or damage. Tighten any loose connectors or wiring clamps.
Repair or replace any damaged wiring.
q Fire coming from hydraulic line
Check that all the hose and tube clamps, guards, and cushions are securely fixed in position.
If they are loose, they may vibrate during operation and rub against other parts. This may lead to damage to
the hoses, and cause high-pressure oil to spurt out, leading to fire damage or serious injury.
