CHAPTER 5 MAINTENANCE AND INSPECTION

3 Scheduled Service Chart

1. As a rule, provide scheduled service every 500,000 copies.
2. Check the Service Book before setting out for a visit, and take parts ex-
pected to require replacement.
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.
