Periodic Replacement Of Parts - Hitachi ZAXIS 70 Operator's Manual

PERIODIC REPLACEMENT OF PARTS

To ensure safe operation, be sure to conduct periodic in-
spection of the machine. In addition, the parts listed below,
if defective, may pose serious safety/fire hazards. It is very
difficult to gauge the extent of deterioration, fatigue, or
weakening of the parts listed below simply by visual in-
spection alone. For this reason, replace these parts at the
intervals shown in the table below. However, if any of these
parts are found to be defective, replace before starting op-
eration, regardless of the interval.
Also, when replacing hoses, check the clamps for defor-
mation, cracks, or other deterioration, and replace as nec-
essary.
Be sure to perform periodic inspection of all hoses, as
shown below, and replace or retighten any defective parts
found, as necessary.
Consult your authorized dealer for correct replacement.
