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 for damage and wrong capacity of the fuse and any sign of disconnection or short circuit in the electrical
wiring. Check also for loose terminals and tighten any loose parts.
Check the wiring of the "battery", "starting motor"and "alternator"carefully, in particular.
Always check if there is any accumulation of flammable material around the battery, and remove such flammable
material.
Please contact your Komatsu distributor for investigation and correction of any problems found.
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 bolts.
The proper inflation pressure is shown below.
Tire size
23.5-R25 (standard)
750/65 R25 (30/65 R25) (if equipped)
NOTICE
If the tires are used when the inflation pressure is less than the value given in the table above, the rim may be damaged.
Always keep the tire inflation pressure within +0 to +0.03 MPa (0.3 kg/cm
CHECK WATER SEPARATOR
The water separator and fuel prefilter (1) are made one and
composed of (2) to (4) in the lower section.
1. Water and sediment on the bottom can be checked through
transparent cap (2). If there is water or sediment, prepare a
container to receive it under drain hose (4).
2. Loosen drain valve (3) to drain the water.
3. If fuel starts flowing out through drain hose (4), close valve (3)
immediately.
