NOTICE
If the nitrogen gas charge pressure in the accumulator is low and operations are continued, it becomes
impossible to release the remaining pressure inside the hydraulic circuit if a failure occurs on the ma-
chine.

Replace the accumulator every 2 years or every 4000 hours, whichever comes sooner. Ask your Komatsu dis-
tributor for replacement.
The accumulator is installed to the position shown in the figure.

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

Check the clamps (1) to (15) visually and with your fingers that there are no loose bolts or hardening of the rub-
ber.
If there is any problem, the related parts must be replaced. Ask your Komatsu distributor for replacement.
