METHOD FOR CHECKING FOR LOOSENESS OF ENGINE HIGH-PRESSURE PIP-
ING CLAMP, HARDENING OF RUBBER
NOTICE
Make sure that high-pressure pipes are correctly attached with clamps. If engine operation is continued
without the full clamp installed correctly, the high-pressure pipes may break from vibration.
Check the clamps (1) to (19) for high-pressure pipe visually and with your fingers that there are no loose mount-
ing bolts or hardening of the rubber.
If there is any problem, the related parts must be replaced. Ask your Komatsu distributor for replacement.
METHOD FOR CHECKING FOR MISSING FUEL SPRAY PREVENTION CAP,
HARDENING OF RUBBER
The fuel spray prevention cap acts to prevent the fuel from coming into contact with high-temperature parts of
the engine and causing a fire if the fuel should leak or spray out.
Check the fuel spray prevention caps (1) to (16) visually or with a finger to see if any of them has slipped off, or
any bolt is loosened, or the rubber part is hardened.
