OPERATION

3-60
Check electric wiring 0.
CAUTION
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 wir-
ing. 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 battery, and remove such flammable material.
Please contact your Komatsu distributor for investigation and correction of the cause.
Check monitor panel 0.
1. Turn the starting switch to the ON position.
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 inspec-
tion.
