OPERATION
CHECK BEFORE STARTING
Always perform the procedures in this section before starting the engine each day.
CHECK COOLANT LEVEL, ADD COOLANT
WARNING
Do not open the radiator cap unless necessary. When checking the coolant, always wait for the engine to cool down and check
the sub tank.
Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is under high internal pressure.
If the cap is removed to check the coolant level in this condition, there is a hazard of burns. Wait for the temperature to go
down, then turn the cap slowly to release the pressure and remove it carefully.
1. Check that the cooling water in sub tank (1) is between the
FULL and LOW marks.
2. If the level is LOW, remove cap (2) and add the engine coolant
up to the FULL mark.
3. If there is no cooling water in the subtank, remove the cover at
the top of the radiator guard, add water to the radiator through
water filler (3), then add water to the subtank.
4. Check that there is no oil in the engine coolant or any other
problem.
5. After adding coolant, tighten the cap securely.
6. If more coolant is added than normal, then check for water
leakage.
