8.1 CLEANING THE EXTERNAL AND INTERNAL
SURFACES OF THE MACHINE
(1) If the external surface of the machine is stained, clean it with a soft, clean and lint-free cloth.
NOTE: Do not use isopropyl alcohol (IPA) to remove dirt or stains from the molding parts.
Doing so may cause cracks in those parts.
(2) If the inside of the machine is stained, first unplug the power cord from the electrical outlet
and then clean it with a soft, clean and lint-free cloth.
NOTE: Do not use liquid or aerosol cleaners.
(3) If the PF encoder disk or encoder strip is stained, replace it with a new one. Do not try to
clean it.
