PERIODIC REPLACEMENT OF PARTS

To ensure safe operation, be sure to conduct periodic
inspection 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
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.
