5.5 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.

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.

5.6 Extraction hood

Always use the extraction hood 9 while working with the tool (Fig. 4).
Connect the machine to a suitable external dust extractor during all work generating a considerable amount of
dust. The air velocity must be at least 20 m/s (65.6 ft / sec.).
The internal diameter of hose connector 10 (Fig. 4) is 29 mm (1 9/64 in.).
The extraction hood is equipped with a thrust ring brake for milling cutters with thrust ring.
On milling cutters without thrust ring, the brake can be removed by pulling the spring-loaded brake pin upwards
and off.
To reactivate the brake, press the spring-loaded brake pin into the bracket provided until it engages.

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 power tool is not used for a longer period of time, it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.

much and be damaged in the process.

Determining the causes for existing defects and eliminating these always requires
increased attention and caution. Pull the mains plug beforehand!
