CARE AND MAINTENANCE

The machine requires no maintenance other than the following guidelines.

Under normal working conditions removing the covers and cleaning with dry

compressed air at reduced pressure once a year will be quite sufficient.

Cleaning at more frequent intervals is advisable however, if the unit is

operating in a very dusty environment.

1. Keep the louvres clean to avoid a build up of dirt and oxides inside the

machine which can reduce machine output.

2. Check all cables periodically for condition and secure. They must be in

good condition and not cracked.

3. Always avoid getting particles of metal inside the machine since they

could cause short circuits.
