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. CHECK COOLANT LEVEL, ADD WATER G 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. G 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 side cover and lock it in position securely with side cover support lever (1). 2. Check that the cooling water level is between the FULL and LOW marks on radiator sub-tank (2) (shown in the diagram on the right). If the water level is low, add water through the water filler of sub-tank (2) to the FULL level. 3. After adding water, tighten the cap securely. 4. If the sub-tank is empty, check for water leakage and check the water level in the radiator. If the water level is low, add water to the radiator first, then to the sub-tank. 3-34 WARNING
