Komatsu — CHECK BEFORE STARTING ENGINE, ADJUST

OPERATION OPERATION CHECK BEFORE STARTING Always carry out the items of the checks in this section before starting the engine each day. CHECK COOLANT LEVEL, ADD WATER 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 drain the coolant 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 before removing it. 1.

Open the engine side cover on the left side of the chas- sis, and check that the coolant is between the FULL and LOW marks on sub-tank (1). If the water level is low, add water to the FULL level through the water filler port in sub-tank (1). REMARK In summer, the coolant may overflow from the sub-tank drain hose. This is no problem. It occurs because too much coolant has been added. 2. After adding water, tighten the cap securely. 3. If the sub-tank is empty, check for leakage of water, then add water to the radiator and sub-tank. 4. After adding water, close the engine side cover. 3-44
