MAINTENANCE
Stylus
Before playing a record, clean the stylus with a soft brush. Brush
the stylus from back to front. Never attempt to clean the stylus with
your finger tip. If a fluid stylus cleaner is used, make sure not to
moisten the stylus too much.
Cabinet
Clean the cabinet and dust cover periodically with a soft dry cloth.
If the stains are difficult to remove, use a cloth moistened with a
mild detergent solution. Do not use solvents such as alcohol, ben-
zine or thinner, since they will damage the finish.
Lubrication
The turntable requires no periodic lubrication. The motor shaft is
lubricated at the factory for the life of the turntable.

shelves, the cabinet, the floor, etc.) to the turntable, where it is picked up by
the stylus, amplified and reproduced through the speakers once again.
