Komatsu — 12.1 CHECK BEFORE STARTING ENGINE

12. OPERATION CHECK OIL LEVEL IN ENGINE OIL PAN, ADD OIL WARNING The parts and oil are high temperature immediately after the engine is stopped, and may cause serious burns. Wait for the temperature to go down before starting the opera- tion. 1. Open the inspection window at the rear left side of the machine. 2. Remove dipstick G and wipe the oil off with a cloth. 3. Insert dipstick G fully in the oil filler pipe, then take it out again. 4. The oil level should be between the H and L marks on dipstick G . If the oil level is below the L mark, add engine oil through oil filler F . For details of the oil to use, see “20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”.

The dipstick has level markings on both sides. One side gives the levels for measuring when the engine is stopped (ENGINE STOPPED) and the other side gives the levels for when the engine is idling (ENGINE IDLING). When measuring the oil level, measure with the engine stopped and use the side of the dipstick marked ENGINE STOPPED. 5. If the oil is above the H mark, drain the excess engine oil from drain valve 1 , and check the oil level again. 6. If the oil level is correct, tighten the oil filler cap securely, then close the inspection window. REMARK When checking the oil level after the engine has been operated, wait for at least 15 minutes after stopping the engine before check- ing.

Checking the oil level with the engine idling may be allowed, if the following precautions are thoroughly satisfied: Check that the engine water temperature gauge shows green range. Use the side of the dipstick marked ENGINE IDLING. Remove the oil filler cap. If the machine is at an angle, make it horizontal before checking. 2-38
