Prior to cleaning, be sure to turn off the power switch and disconnect the power cord plug
from the outlet.
After cleaning, make sure that the areas that were cleaned are completely dry before
connecting the power cord.
Do not use flammable sprays inside or near the unit (e.g. when cleaning the

Take precautions against fire and ensure ventilation when using alcohol, and store
the alcohol in a safe place after use. Also note that use of other solvents can damage
the rubber rolls and resin inside the unit, resulting in malfunctions.
