METHOD FOR CHECKING AIR CONDITIONER COMPRESSOR OPERATION

Check the following 2 items.
1) When the air conditioner switch is turned ON-OFF, do the air conditioner compressor and the magnet clutch

also turn ON-OFF?

2) Is any abnormal noise generated by the magnet clutch or the air conditioner compressor body?

If any abnormality is found, ask your Komatsu distributor to have the parts disassembled, repaired, or re-
placed.

METHOD FOR CHECKING FOR LOOSENESS OF ENGINE HIGH-PRESSURE PIP-
ING CLAMP, HARDENING OF RUBBER

Check visually and touch by hand to check that there is no hardening of the rubber and no loose bolts of the
mounting clamps (2 places) for the high-pressure piping between the supply pump and the common rail.
Replacement of the high-pressure piping must be made as an assembly.
Replacement is required if any trouble is found. Ask your Komatsu distributor for that work.
