Check Electric Wiring
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.
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
terminals 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.
Check Function of Horn
1. Turn the starting switch to the ON position.
2. Confirm that the horn sounds immediately when the horn
button is pressed.
If the horn does not sound, contact your Komatsu distributor for
repair.
