6 GENERAL PRECAUTIONS
FIRE PREVENTION FOR FUEL AND OIL
Fuel, oil, and antifreeze can be ignited by a flame. Fuel is particularly flammable and can be hazardous.
Always observe the following:
• Keep any flame or lighted cigarette away form flammable fluids.
• Stop the engine and do not smoke when refueling
• Tighten all fuel and oil caps securely
• 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.
PRECAUTIONS WHEN HANDLING AT HIGH TEMPERATURE
• Immediately after operations are stopped, the engine oil and hydraulic oil are at high temperature and are
still under pressure. Attempting to remove the cap, drain the oil or water, or replace the filters may lead to
serious burns. Always wait for the temperature to go down, and follow the specified procedures when carry-
ing out these operations.
• To prevent hot water from spurting out, stop the engine, wait for the water to cool, then loosen the cap slowly
to relieve the pressure before removing the cap.
(When checking if the water temperature has gone down, put your hand near the front face of the radiator
and check the air temperature. Be careful not to touch the radiator).
• To prevent hot oil from spurting out, stop the engine, wait for the oil to cool, then loosen the cap slowly to
relieve the pressure before removing the cap.
(When checking if the oil temperature has gone down, put your hand near the front face of the hydraulic tank
and check the air temperature. Be careful not to touch the hydraulic tank).
