Service and maintenance

MAFELL machines are designed to be low in maintenance.
Replace the carbon brushes at the latest after 125 - 150 operating hours. The spare parts can be referenced in
chapter 9.
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.

6.1 Storage

If the milling motor is out of service for a lengthy period of time, it should be thoroughly cleaned. Spray bright
metal parts with a rust inhibitor. Close the portal connector with the supplied covering cap Z (Fig. 4).
