Prevention Of Burns; Fire Prevention - Komatsu D65EX-12 Operation & Maintenance Manual

GENERAL PRECAUTIONS

PREVENTION OF BURNS

Hot coolant
To prevent burns from hot water or steam spurting out
when checking or draining the coolant, wait for the water to
cool to a temperature where it is possible to touch the radi-
ator cap by hand before starting the operation. Even when
the coolant has cooled down, loosen the cap slowly to
relieve the pressure inside the radiator before removing the
cap.
Hot oil
To prevent burns from hot oil or other parts when checking
or draining the oil, wait for the oil to cool to a temperature
where it is possible to touch the cap by hand before start-
ing the operation. Even when the oil has cooled down,
loosen the plug slowly to relieve the internal pressure
before removing the plug.

FIRE PREVENTION

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:
Do not smoke or use any flame near fuel or oil.
Stop the engine before refueling.
Do not leave the machine while adding fuel or oil.
Tighten all fuel and oil caps securely.
Do not spill fuel on overheated surfaces or on parts of
the electrical system.
Use well-ventilated areas for adding or storing oil and
fuel.
Keep oil and fuel in the determined place and do not
allow unauthorized persons to enter.
After adding fuel or oil, wipe up any spilled fuel or oil.
When carrying out grinding or welding work on the
chassis, move any flammable materials to a safe place
before starting.
When washing parts with oil, use a non-flammable oil. Diesel oil and gasoline may catch fire, so do not
use them.
Put greasy rags and other flammable materials into a safe container to maintain safety at the work place.
