3.1.2 CHECKING BEFORE STARTING ENGINE
Check the followings in this section without starting the engine and before starting the first work every day.
[1] CHECKING/REFILLING ENGINE COOLANT
• 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 radiator 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
radiator cap slowly to release the pressure and remove it carefully.
1. Stop the machine at leveled location.
2. Open the pump room door on the machine right side.
3. Check the cooling coolant level in the sub tank (1) to be between
FULL and LOW marks.
4. If the coolant level is lower than the LOW level, use the following
procedure to refill with tap water.
(1) Remove the cap of the sub tank (1) and fill water from the
filler opening to the level FULL.
(2) After refilling with water, securely install the cap of the sub
tank (1).
If the sub tank is empty, there is probably leakage of water. After inspecting, repair any
abnormality immediately. If there is no abnormality, check the water level in the radiator. If the
water level is low, add coolant to the radiator, and then fill the sub tank (1).
