12. OPERATION 12.1.4 OPERATIONS AND CHECKS BEFORE STARTING ENGINE WARNING If the control levers are touched by accident, the work equip- ment may move suddenly. When leaving the operator's com- partment, always set the safety lever securely to the LOCK position. Before starting the engine, use a damp cloth to wipe off the dust accumulated on the top surface of the battery or on the starting motor and the alternator. 1. Check that parking brake switch 1 is at the ON position. 2. Check that directional lever 2 is at the N position. When starting the engine, if directional lever 2 is not at the N position, the engine will not start. 3.
Lower the bucket to the ground, then check that work equipment control lever 3 is locked by safety lock 4 . 4. Insert the key in starting switch 5 , turn the key to the ON position, and check that the pilot lamp lights up. When the starting switch is turned to the ON position before starting the engine, all monitor lamps, gauges, and centralized warning lamps will light up for approx. 3 seconds, and the alarm buzzer will sound for approx. 1 second. When this happens, 88 is displayed on the speedometer, and 8 is displayed on the transmission shift indicator.
If the monitor lamps do not light up, there is probably a failure or disconnection, so please contact your Komatsu distributor for inspection. 2-47
