5.4 Collets
Always use the correct tool size for the respective collet.
Oil the collet a little at the beginning and after longer use.
Unscrew the union nut 3 with the collet 2 (Fig. 1).
Tilt out the collet 2 to the side.
If the collet is jammed, loosen it with a rubber hammer by a light blow from behind.

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 machine is not used for a longer period of time, it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
Danger
To protect the thread, only screw the union nut 3 lightly onto the spindle 1, but
do not tighten when no tool is inserted. Collet 2 could get pressed together too
much and be damaged in the process.
Danger
Pull the power plug during all service work.
