Komatsu — 12.1.2 CHECK BEFORE STARTING

OPERATION CHECK THE ELECTRICAL WIRING WARNING Frequently blown fuses, or if there are signs of arcing, indicate an electrical short circuit may be the cause. Locate the cause and repair it. Accumulation of all flammable material (dead leaves, twigs, grass, etc.) around the battery may cause fire, so always remove such material. Check for damaged fuses and any sign of disconnection or short circuit in the wiring. Check also for loose parts. Check the following points carefully. Battery Starting motor Alternator When performing walk-around checks before starting, always check for an accumulation of flammable material around the battery. If found, remove the flammable material.

Please contact your distributor for investigation and correction of the cause. CHECK FOR WATER AND SEDIMENT IN THE WATER SEPARATOR (if equipped) The water separator separates the water from the fuel so that only fuel is delivered to the combustion chamber. If the float (2) is at or above the red line (1), drain the water from the separator. If a machine is equipped with a water separator, the water from the fuel tank must still be emptied before starting the machine each day. WA450-3MC 2-42
