3.MAINTENANCE

3.1INSPECTION, CLEANING AND LUBRICATION

The following maintenance should be performed once annually, under normal use.

Operational Inspection

1.If operating properly, the Professional Puncher-A1will punch the same types of copy paper and cover materials handled by the copier/printer. It will run at the speed of the printer.

2.Hole quality will vary between different grades of paper.

External Cleaning

1.Make sure you disconnect the Professional Puncher-A1from its power source before cleaning. The cover may be cleaned with a soft cloth moistened with mild detergent and warm water.

2.Do not use chemical cleaners or solvents as these may have a harmful effect. Use detergent sparingly to avoid contact with electrical components.

Internal Cleaning

Before internal cleaning, be sure to disconnect power to the Professional Puncher- A1 and ensure that you retain control of the power cord.

Occasionally, it will be necessary to remove the rear cover and remove paper dust built up around the motor and other electrical components. Use a vacuum cleaner if possible. A small paintbrush can also be used but extreme care should be used around electrical components.

Internal Inspection

Whenever the cover has been removed for corrective maintenance, visually inspect for defects such as loose screws or nuts, abraded wire insulation, loose terminals, etc. Correct any defects before returning the machine to service.

Lubrication Points and Recommended Lubricant

•Lubricate the punch pins and/or the felt pad once every 50,000-punch cycles with oil (High Quality Machine Oil is recommended).

•Method:

1.Sparingly depress the Pin Guide so that the Punch Pins protrude from the bottom plate, oil the ends of the pins and wipe clean.

2.Apply oil directly to the felt pad (If so equipped).

3.Apply two drops of oil to each of the two shoulder bolts and springs.

•If Punch Drive Module Assembly is ever removed for service, check for sufficient grease on the cranks.
