PERIODIC REPLACEMENT OF PARTS
To ensure safe operation, be sure to conduct periodic inspec-
tion of the machine. In addition, the parts listed below, if defec-
tive, 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 inspection 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 operation, regardless of the interval.
Also, when replacing hoses, check the clamps for deformation,
cracks, or other deterioration, and replace 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.
