2. If lit, immediately clean or replace the element.

CHECK ELECTRIC WIRING
●
If the fuses frequently blow, if there are traces of short
circuits in the electrical wiring, locate the cause immedi-
ately and carry out repairs, or contact your Komatsu dis-
tributor 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, wrong fuse capacity, and any sign of discon-
nection or short circuit in the electric wiring. Check for loose termi-
nals and tighten any loose parts.
In particular check the wiring of the "battery", "starting motor" and
"alternator" carefully.
When carrying out walk-around checks or checks before starting,
always check if there is any accumulation of flammable material
around the battery, and remove it.
Please contact your Komatsu distributor for investigation and cor-
rection of the cause.
CHECK FUNCTION OF HORN
1. Turn the starting switch to the ON position.
2. Confirm that the horn sounds without delay when the horn
button is pressed. If the horn does not sound, ask your
Komatsu distributor for repair.
