MAINTENANCE PROCEDURE

4-107

CHECK FOR LOOSENESS OF HIGH-PRESSURE PIPING CLAMP, HARDENING OF RUB-
BER

4

Check visually and touch by hand to check that there are no loose mounting bolts for high-pressure piping clamps
(1) - (34) in the diagram and no hardening of any rubber parts. If any problem is found, the part must be replaced.
In this case, please ask your Komatsu distributor to carry out the replacement.

NOTICE
If the engine continues to be used when there are loose bolts, hardened rubber, or missing parts, there is
danger of damage or breakage occurring due to vibration and wear at the connections of high-pressure
piping. Always check that the proper high-pressure piping clamps are correctly installed.
