CHECK ELECTRIC WIRING
WARNING
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, wrong fuse capacity, and any sign of disconnection or short circuit in the electric wiring. Also,
check and tighten any loose terminals.
Particularly, check the wiring of the “battery“, “starting motor“ and “alternator“ carefully.
When checking around the battery, make sure there is no accumulation of flammable material. Remove all flam-
mable material.
Please contact your Komatsu distributor for investigation and correction of the cause.
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 problem 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).
