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 tem-
perature to go down, then turn the cap slowly to release the
pressure before removing it.
CAUTION
When adding coolant, use the step and handrail provided, and
support your body securely.
1. Open cover (1) of the platform on the right side of the
machine.
2. Check that the coolant level is between the FULL and LOW
marks on radiator sub-tank (2). If the coolant level is low, add
coolant through the coolant filler of sub-tank (2) to the FULL
level.
3. After adding coolant, tighten the cap securely.
4. If sub tank (2) is empty, check for coolant leakage, then
check the coolant level in the radiator. If the coolant level is
low, add coolant to the radiator, then add coolant to sub tank
(2).
If the volume of coolant added is more than usual, check for
possible leakage.
Confirm that there is no oil in the coolant.
