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 is found to be defective by inspection, replace it be-
fore starting operation, regardless of the interval.
Also, when replacing hoses, check their clamps for de-
formities, cracks, or other deterioration, and replace them
as necessary.
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.
