4. PERIODIC REPLACEMENT OF IMPORTANT
COMPONENTS
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.
For the hose part, if any distortions or cracks in the hose clamp or deteriorations of O-rings are
found, please replace them.
