7. Dust Removal - From time to time, it will be necessary to clean excessive
dust that accumulates in the motor cover. To remove this dust, remove
the motor cap (see instructions for replacing carbon brushes to remove
motor cap). If compressed air is available, use it inside the cover and the
motor armature air cooling vent. If air is not available, remove excessive
dust with a dry brush. If necessary, use a cloth moistened with detergent
to clean the cover, and blow into the air cooling vents to clean around the
armature.
DO NOT USE
any volatile liquid as a cleaner (i.e. paint thinner
or alcohol).
Periodically cleaning the inner threads on handpiece collets will ensure
their easy collet removal when changing sizes. Twist a clean rolled-up
piece of tissue paper in and out of the threaded area.
