Collets
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.
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
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 power tool must be made aware of the operating manual, calling
particular attention to the chapter “Safety instructions”.
This operating manual only deals with the power tool and does not take the installation situation into account.
Please take note of any other operating manuals.
5.1.1
Switching on
Push the power switch 5 (Fig. 1) forward until it engages. If the power tool is connected to the mains voltage,
the setting wheel X (Fig. 2) lights up in blue (BU) and the power tool accelerates to the previously set speed
after 0.2 s with a soft start. The duration of the soft start depends on the set speed and is approx. 1.2 s at
maximum speed.
5.1.2
Switching off
Push onto the rear end of the power switch 5 (Fig. 1). The switch audibly jumps back to off position. The
lighting on the setting wheel X (Fig. 2) goes out and the motor coasts to a standstill.
