4.18.6 CHANGING COOLANT
HANDLING OF COOLANT
Inside the radiator, high pressure steam is generated. Do not loosen or remove the radiator cap when
the coolant is under high pressure and high temperature.
•After the coolant cools down, turn the cap slowly to release the pressure.
Engine anti-freeze/coolant liquid is flammable and can cause injury.
•Keep anti-freeze /coolant liquid away from flames and sparks.
•Avoidthe eyes and skin contacting with the coolant.
If the coolant gets into the eyes or contacts the skin, flush the eyes or skin with plenty of fresh
water, and seek medical attention.
PAY ATTENTION TO HOT PARTS
Immediately after operation, the oil is hot and it may result in burns. Wait until the oil temperature
cools down before attempting to change the element.
Use clean soft water for coolant in which lime deposit is not produced.
Water has corrosiveness at engine operating temperature. When being shipped from the factory, the
coolant mixed with "Long Life Coolant" at the rate of 50% is used to prevent rust and freezing of the
cooling system.
•Non-amine antifreeze mixture is used for this machine.
•Change the coolant earlier than the specified period when it was dirty and/or bubbling.
1. Stop the engine, open the engine hood, and
wait until the coolant cools down before
starting the work.
