Operation 3.3 Operation Check electric wiring If fuses are frequently blown or if there are traces of short- circuiting on the electrical wiring, promptly ask your KOMATSU distributor to locate the cause and make the repair. Keep the top surface of the battery clean and check the breather hole in the battery cap. If it is clogged with dirt or dust, wash the battery cap to clear the breather hole. Check for damage and wrong capacity of the fuse and any sign of disconnection or short circuit in the electric wiring. Check also for loose terminals and tighten any loose parts. Particularly, check the wiring of the “battery“, “starting motor“ and “alternator“ carefully.
When carrying out checks around the battery, always check if there is any accumulation of flammable material around the bat- tery, and remove such flammable material. Please contact your KOMATSU distributor for investigation and correction of the cause. Check monitor panel OFF 1. Turn the starting switch to the ON position. ON START GK032182 2. Check that all the monitors, gauges, and the central warning lamp light up for approx. 3 seconds and the alarm buzzer sounds for approx. 1 sec. If the lamps do not light up, there is probably a failure or dis- connection, so contact your KOMATSU distributor for inspection. GK032010 WA150-5H – VEAM934100 3-61 CAUTION CAUTION
