3. 1. 2 CHECKING BEFORE STARTING ENGINE
Check the following in this section without starting the engine and before starting work every day.
[1] CHECKING/REFILLING ENGINE COOLANT
• Do not open the radiator cap when engine is hot. Inspect the coolant in the sub tank after
the engine is cold.
• The coolant is at elevated temperature after the engine is stopped. Besides, pressure is
accumulated inside the radiator. If the cap is opened in this state, the coolant may blow
out, causing burns. When removing the radiator cap, turn it slowly to release pressure
after the coolant temperature lowers and carefully remove it.
1. Place the machine on a level surface.
2. Open the machinery cover.
3. Inspect the sub tank (1) level and check that the coolant is
between "FULL" and "LOW".
4. If the coolant level is lower than the “LOW” level, use the
following procedure to refill tap water.
(1) Remove the sub tank (1) cap and refill water from the
feed port to the "FULL" level.
(2) After refilling coolant, securely close the sub tank (1)
cap.
If the sub tank is empty, water leaks are to be considered. Repair if any abnormality is found
after inspection.
If no abnormality is found, inspect the coolant level in the radiator. If coolant is low, feed
coolant to the radiator and then to the sub tank.
[2] CHECKING OIL LEVEL AND REFILLING OIL IN ENGINE OIL PAN
As parts and oil will be hot immediately after the engine stops, you may suffer burns.
Wait until the temperature drops, then start the work.
