8.2 PERIODIC REPLACEMENT OF CRITICAL PARTS
To use your machine safely for a long period of time, replace the parts listed as important parts relating
specially to safety and fire periodically.
These parts are susceptible to change in the quality, wear and deteriorate over time. Since it is difficult to
determine their degrees in a regular maintenance, they should be replaced with the new ones after a
certain period of time even if no abnormalities are detected to guarantee perfect and consistent
functionality.
These parts need repair or replacement when any abnormality is detected, even before the exchange
time comes.
As to the hoses, if any distortions or cracks in hose clamps or deteriorations in O-rings, replace them also.
