OPERATION
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 that the fuses are not damaged, that the fuses are of the correct capacity, and that there are no signs of short
circuits or disconnections in the electric wiring. Check also that there are no loose terminals or connectors. Tighten
any loose parts.
In particular, check the wiring of the battery, starting motor, and alternator.
Be also sure to check that there is no flammable material accumulated around the battery. Remove any such
flammable material.
Please consult your Komatsu distributor about the repairs and causes of problems.
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 Section "HANDLING THE TIRES
(PAGE 3-155)" for details.
CHECK CONDITION OF WINDOW WASHER SPRAY
