6. 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 spurting out when checking or
draining the oil, wait for the oil to cool to at temperature
where it is possible to touch the cap or plug by hand before
starting the operation. Even when the oil has cooled down,
loosen the
cap or plug slowly to relieve the internal pressure before
removing the cap or plug.
FIRE PREVENTION
Fire caused by fuel or oil
Fuel, oil, antifreeze, and window washer liquid are particularly
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.
