12. OPERATION CHECK ELECTRIC WIRING WARNING If fuses are frequently blown or if there are traces of short circuit on the electrical wiring, locate the cause and carry out repair. Accumulation of flammable material (dead leaves, twigs, grass, etc.) around the battery may cause fire, so always check and remove such material. 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.
Check the wiring of the “battery”, “starting motor” and “alternator” carefully in particular. When carrying out walk-around checks or checks before starting, 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 the cause. 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 proper inflation pressure is shown below.
NOTICE The appropriate tire inflation pressure differs according to the type of work, so see “12.18 HANDLING THE TIRES”. CHECK WATERPROOF/FIREPROOF DIVIDING WALLS WARNING If the wall between the engine room and hydraulic pump or the rubber sheet are damaged or have come off, and the hydraulic hose breaks, oil will spray onto the high-temperature parts of the engine, and this will lead to fire or other secondary damage. If the wall or rubber sheet are damaged or have come off, please contact your Komatsu distributor for repairs. Check that there is no damage or missing parts of rubber sheet 2 or wall 1 between the engine room and hydraulic pump.
If any damage or missing parts are found, please contact your Komatsu distributor for repairs. 2-41 Tire size Inflation pressure 45/65-45-58PR (L5) (standard) 0.67 MPa (6.8 kgf/cm2, 96.56 PSI)
