Periodic Replacement Of Parts - Hitachi ZX27U-2 Operator's Manual

PERIODIC REPLACEMENT OF PARTS

To ensure safe and long trouble free operation, be sure to
conduct periodic inspections of the machine. In addition,
the parts as listed below are directly related to safety op-
eration so that they are recommended to be periodically
replaced. These part material properties will change due to
aging, or repeated operation may cause deterioration, wear,
and/or fatigue of these parts, possibly resulting in serious
safety/fire hazards. It is very difficult to gauge the remaining
service lifetime of these parts simply by visual inspection
alone. For this reason, replace these parts at the intervals
shown in the table below. If any of these parts are found to
be defective by inspection, immediately replace it regard-
less of the recommended intervals.
Consult your authorized dealer for correct replacement.
