Service and maintenance

Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.

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 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.

6.2 Cutter

The cutters used on the machine must be freed from
resin regularly as clean tools improve the cutting
quality.
For cleaning, only acid-free but not highly alkaline
cleaning agents may be used.
Deresinification is carried out by soaking the cutters
for 24 hours in paraffin or commercially available
resin remover.

6.3 Storage

If the machine is out of service for a lengthy period of
time, it should be thoroughly cleaned (see chapter
5.1). Spray bright metal panels with a rust inhibitor.
Store the machine only in dry rooms and protect it
from the effects of weather.
Elimination
Check power supply
Take the machine to a MAFELL
customer service shop
Check mains back-up fuses
Switch off the machine
immediately. Remove the machine
from the workpiece and replace the
cutter
Replace cutter
Connect to an external extraction,
without
e.g. portable dust extractor
