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 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.
Elimination
Check power supply
Replace fuse
Take the machine to a MAFELL
customer service shop
Check mains back-up fuses
Regrind drill bit or replace
Connect to an external exhaustion,
e.g. portable dust extractor
