Points to Note Before Servicing

• At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.
• Be sure to disconnect the power plug on a regular basis and remove dust and dirt accumulated around the outlet with dry
cloth.
CAUTION:
Leaving the power plug connected for a long time in an environment having a lot of dust, moisture, or oily smoke will
cause a fire. (Because dust accumulated in the surrounding area will absorb moisture and cause an insulation failure)
• Be careful not to be injured by burrs of edges, sharp corners or protrusions.
CAUTION:
Hazardous area such as corners, edges, springs and other sharp sections may be remaining on products. Always be
aware of the presence of hazardous area to avoid injury caused by contacting and/or striking those area, by not over-
concentrating on service work.
