MAINTENANCE 24.3 CHECK BEFORE STARTING 24.3.1 CHECK MONITOR PANEL Check the monitor lamps, the gauges and the warning lamp see “12.1.2 CHECK BEFORE STARTING” on page 2-42. If any monitor lamp does not light up, ask your Komatsu distributor to inspect that monitor lamp. Do not carry out the checks before starting using only the monitor; always carry out also the items specified for the periodic maintenance. 24.3.2 CHECK COOLANT LEVEL, ADD WATER Normally, do not open the radiator cap. Always wait for the engine to cool down before checking the water level, and check using the subtank.
Open the top cover at the front of the engine hood in the middle of the machine, and check that the coolant level is between the FULL and LOW marks on sub-tank (1). If the coolant level is low, add water to the FULL level through the water filler in subtank. After adding water, tighten the cap securely. If subtank (1) is empty, check for water leakage, then add water to the radiator and subtank. 24.3.3 CHECK FUEL LEVEL, ADD FUEL WARNING When adding fuel, never let the it overflow. This may cause a fire. If you spill fuel, thoroughly clean up any spillage. 1. Turn the engine starting switch to the ON position, then check the fuel level with fuel gauge (1).
After checking, return the starting switch to the OFF position. 2. Upon completion of work, add fuel through filler (2) until the fuel tank is full. For details of the fuel to use, see 20 FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE on page 3-10. 3. After adding fuel, tighten the cap securely.
