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
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.
