METHOD FOR CHECKING ELECTRIC WIRING
• If fuses are frequently blown or if there are traces of short-circuiting on the electrical wiring,
promptly ask your Komatsu distributor to locate the cause of it and to perform the repair.
• Keep the top surface of the battery clean and check the vent hole in the battery cap. If it is clogged
with dirt or dust, wash the battery cap with water to clear the vent hole.
NOTICE
In particular, inspect the wiring of "battery", "starting motor", and "alternator" with care.
Perform the following inspection.
• Perform inspection to confirm that the fuses have no defect and their capacity is proper.
• Perform inspection to confirm that there is no disconnection or trace of short-circuiting in the electric wiring
and no damage to the coating.
• Perform inspection to confirm that there is no loose terminals, and tighten any loose parts if found.
• Always check if there is any accumulation of combustible material around the battery, and remove such
combustible material.
METHOD FOR CHECKING FUEL LEVEL, ADDING FUEL
When adding fuel, never spill the fuel or let it overflow. This may cause fire.
If any fuel has spilled, wipe it up completely. If fuel has spilled over soil or sand, remove that soil or
sand.
Fuel is highly flammable and dangerous. Do not bring any open flame close.
When performing operations on slopes, to prevent the engine from sucking in air, pay careful attention to the
amount of fuel remaining in the tank.
