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” .
The useful life of the motor ends when the replaced motor brushes wear out (after approximately 2000 hours of spindle operation). When
this happens, replace it with a new spindle motor (optionally available).
Turn the screw using
the included
hexagonal wrench.
