Check Working Lamp Switch
Turn the lamp switch to the ON position and check that the
working lamp light up.
If the lamps do not light up, there is probably a broken bulb or
disconnection in the wiring, contact your Komatsu distributor
for repairs.
Check Electric Wiring
q If the fuses frequently blow or if there are traces of short circuits in the electrical wiring, locate the
cause and immediately perform repairs, or contact your Komatsu distributor for repairs.
q 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 clean the breather hole.
Check for damage to the fuse, that a fuse of the specified capacity is being used, that there are no signs of any
disconnection, breakage, or short circuit in the wiring. Also check for loose terminals, and tighten any loose termi-
nals found.
Be sure to check wiring for the battery, starting motor, and alternator.
In addition, if any flammable material is accumulated around the battery, remove it.
For troubleshooting and repairs, contact your Komatsu distributor.
