The sensor lenses and the underside of the reflector should be dusted
regularly, especially if set-off spray powder is used on the stock.
A thorough cleaning of the sensor lenses is best achieved by raising the feed
bed and then using a soft brush to clear away all dust.

Regular Maintenance
The UFO Folding Machine has been designed for minimum maintenance;
however, the following items will need attention.
Weekly
-
The two roller shafts on the feed bed should be cleaned and
sparingly oiled (see page 37, items 50 and 60 of the spare parts
manual).
The counter sensor lenses and reflector must be dusted
regularly to ensure reliable counter operation (see page 25 of
this book).
This will also affect the feed if dirty.
Monthly
-
The air filter, mounted on the compressor, must be removed
and cleaned. Access to the compressor is made by loosening
the two screws at the top surface of the base access door (fold
plate end). (See page 25 of the parts manual).
3 monthly - Lubricate the two idler gears on the swinging perforating unit
using a light machine oil.
6 monthly - The drive motors have carbon brushes with an average life of
1000 hours. These brushes should be inspected periodically,
call our Service Department for advice.
(See pages 21 and 35 of the parts manual).
