carrying out maintenance work on the motor.
The Ferm machines have been designed to operate over
a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon
proper machine care and regular cleaning.
Cleaning
Regularly clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation slots free
from dust and dirt.
If the dirt does not come off use a soft cloth moistened
with soapy water. Never use solvents such as petrol,
alcohol, ammonia water, etc. These solvents may
damage the plastic parts.
