- To unclamp the tool, move lever 6 (Fig. 3) forward up to the stop.
- Pull off the tool to the front.
- Push the new tool into the tool holding fixture up to the limit stop.
- Check the tool's seat.
- To clamp the tool, move the lever back to its original position.

4.4 Collets

4.4.1 Information on the use of collets:
- Please always use the correct milling cutter size for OZ collets (DIN 6388) and also for ER16 collets (DIN
6499).
- Please always click the collet into the union nut first, then insert the milling cutter.
- If jammed, please loosen the collet with a square timber or rubber hammer with a light blow from behind (no
metal tool!).
- Please oil the collet collets at the beginning as well as after longer use as otherwise they can get stuck.
- A significantly better concentricity can also be achieved by using a solid lubricant (e.g. Molykote P-40) or by
lightly greasing the collets.
4.4.2

Recommended tightening torques (observe overall system)

Tightening torque for union nut / collet = 10 -11 Nm
Tightening torque for clamping collar 43 mm = 7 Nm
The Euro neck mount "V" should not be smaller than dimension "h" (Fig. 8). Dimension "h" amounts to 20 mm.
Clamp the milling motor as far as possible across the entire mounting diameter in the Euro neck mount "V1"
(Fig. 8). Tighten clamping screw „W" with max. 7 Nm. (Fig. 9)
As far as possible, avoid punctual clamping (for instance using a grub screw) in the Euro neck mount „V2" (Fig.
10).
4.4.3 Maximum speed when using a collet adapter
The recommended maximum speed for the use of the collet chuck adapter OZ and the collet chuck adapter ER
is max. 16000 rpm.

Operation

5.1 Initial operation

Personnel entrusted to work with the milling motor must be made aware of the operating manual, calling
particular attention to the chapter "Safety instructions".
This operating manual only deals with the milling motor and does not consider the installation situation. Please
take note of any other operating manuals.
Danger
To protect the thread, only screw the union nut 3 (Fig. 1) lightly onto the spindle 1
(Fig. 1), but do not tighten when no tool is inserted. Collet 2 (Fig 1.) could get
pressed together too much and be damaged in the process.
