Check electric wiring
CAUTION
If fuses are frequently blown or if there are traces of short-circuit-
ing on the electrical wiring, promptly ask your KOMATSU distrib-
utor 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 wiring. 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 bat-
tery, and remove such flammable material.
Please contact your KOMATSU distributor for investigation and
correction.
Check parking brake
Check that the parking brake works properly.
If there is any abnormality in the operation of the parking brake
or the brake does not provide the proper braking effect, please
contact your KOMATSU distributor for adjustment.
Check brake pedal
Drive the machine forward and check the effect of the brakes.
If there is any abnormality in the actuation of the brakes, please
contact your KOMATSU distributor to have the brakes adjusted.
Check inflation pressure of tires
Measure the inflation pressure with a tire pressure gauge while
the tires are cool before starting work.
Check for damage or wear to the tires and the rims. Check for
loose wheel hub nuts (bolts).
The appropriate inflation pressure differs according to the type of
work, see "Handling the tires (3-146)".
