3. If you have cleaned a charging wire with alcohol, check to be sure that the solvent has dried before mounting it back to the machine.
4. If the power plug is left connected for a long time in an area subject to excessive dust, humidity, or smoke (containing oil vapor), an insulation fault and,
ultimately, a fire can occur (owing to the build-up of moist dust.)
Be sure to disconnect the power plug on a periodical basis, and wipe the area and the power plug clean with a dry cloth.
