Chapter 4. Preventive Maintenance
This section contains information for maintaining the finisher for continuous failure-
free, high quality performance. Including in this section are procedures for cleaning the
exterior and interior of the finisher.
While performing any maintenance procedure, visually inspect the finisher for loose,
broken or missing cables, connectors or other parts.
PREVENTIVE MAINTENANCE SCHEDULE
For many of the preventive maintenance procedures, there are no set times to perform
them. The determining factor for when to perform a procedure depends on the extent
of use. Finishers that are used more heavily will require more frequent preventive
maintenance.
