Service and maintenance
Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.
Only use our special grease, order No. 049040 (1 kg
tin) for all greasing points.
6.1 Machine
The machine must be regularly cleaned off deposited
dust. The ventilation openings on the motor should be
cleaned with a vacuum cleaner.
The free movement of the moving protective hood
must be ensured. If it does not close by itself after it is
opened, the machine must be delivered to an
authorised MAFELL customer service workshop.

6.2 Tools
The cutter heads used on the machine should be
regularly deresinified, as clean tools improve improve
the cutting quality.
Deresinify them by placing them in petroleum or a
commercially available deresinification agent for 24
hours.
Aluminium tools may only be
deresinified with solvents which do
not corrode the aluminium.
Promptly replace damaged clamping screws and
cutting elements.
The design must not be modified with progressive
tools during servicing.
6.3 Storage
If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
Store the machine only in dry rooms and protect it
from the effects of weather.
Elimination
Check power supply
Replace fuse
Take the machine to a MAFELL
customer service shop
Check mains back-up fuses
Reduce feed speed
