Maintenance

NOTICE
When cleaning the PNC-300, make sure that the main unit's power OFF.
Cleaning the Main Unit
When the main unit becomes dirty, use a dry cloth to wipe it.
Cleaning After Operation
After cutting work is completed, use a vacuum cleaner to clean the PNC-300
main unit and the surrounding area of cutting dust. Be especially careful to
remove the cutting waste from around the pleated part of the bellows cover. If
necessary, move the XY table to the front and rear, and clean the entire cover.
Except when moving the XY table, carry out all cleaning work with the PNC-
300's power OFF.
NOTICE
Do not use a compressed air for such cleaning. Cutting chips in the air
may attach to a portion of the machine and cause malfunctions or
breakdowns.
Replacing the Motor Brushes
The brushes for the spindle motor should be replaced periodically. As a general guide, replacement after every 1,000 hours of spindle rotation
is suggested. For an explanation of how to check the spindle rotation time, see "Display of Spindle Rotation Time".
