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
Mortising chains
The mortising chain used on the machine should be
cleaned and lubricated in a low viscosity oil bath after
two hours of operation. To do so, dismantle the
mortising chain (see chapter 4.3).
Replace the blunt mortising chains or have them
reground at a MAFELL customer service station or by
a suitable sharpening service.
6.2
Storage
Clean the machine thoroughly if the machine is not
used for a longer period of time. Spray blank metal
parts with a rust-proofing agent.
