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

Check electric wiring
WARNING
If the fuses frequently blow, if there are traces of short cir-
cuits in the electrical wiring, locate the cause immediately
and carry out 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, wrong fuse capacity, and any sign of discon-
nection or short circuit in the electric wiring. Check for loose ter-
minals 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 start-
ing, always check if there is any accumulation of flammable
material around the battery, and remove it.
Please contact your KOMATSU distributor for investigation and
correction of the cause.
