Milling
6.8.1 Open locking screws (5.1 and 5.5) and locking lever (5.2) so that milling arm and milling spindle can
be moved freely. The lever (6.3) is slid to the right side out of the lock so that the milling spindle can
be moved freely.
6.8.2 The rotary knob (5.19) is adjusted to the recommended working speed of the bur.
6.8.3 When milling a bar, the model is fixed on the platform to ensure parallel alignment of the milling
arm and the bar. Tighten the locking lever for the rotating movement (5.2) and loosen the locking
screw for horizontal movement (5.1).
6.8.4 Turn the rotary knob (5.19) to adjust the speed recommended for the bur.
Drilling
6.9.1 Determine the desired direction of drilling at the object and close the locking screws (5.1 and 5.5) and
the locking lever (5.2).
6.9.2 Determine the depth of the drillhole with the micrometer screw (5.4). If only the upper screw is used,
the micrometer screw is not turned any longer once the depth stop has been reached. This way
precise adjustment of the depth of the drillhole is ensured. The lever (5.3) is pressed in to the left until
the milling spindle can be moved downward with the lever.
6.9.3 The rotary knob (5.19) is adjusted to the recommended working speed of the bur.
6.9.4 Move the milling spindle downward with the lever (5.3) whilst exerting slight pressure.
7. Clamping of the motor milling spindle/exchange of tools
 Tools may only be exchanged when the motor is switched off!
7.1 Turn clamping lever (5.7) to the right side up to the stop and insert the tool.
7.2 Turn clamping lever (5.7) to the left side up to the stop and clamp in the tool.
7.3 By turning the clamping lever (5.7) to the right side (= approx. half of the way), the drive of the
milling spindle can be locked and the tool is still firmly clamped in. This position is intended to lock a
scraping tool.
8. Exchange of the chuck
9.1 Turn clamping lever (5.7) to the right side up to the stop.
9.2 Open locking screw of the milling spindle (5.6).
9.3 Remove milling spindle from the holding device.
9.4 Loosen union nut (8.1) completely (it may be required to use the bur shank Ø 2.35 mm); remove (pull
off) the milling spindle from the motor.
9.5 Turn the chuck (8.2) jerkily anticlockwise using the chuck key no. 4115 and screw it out, if required
insert counter key no. 4113 in driver (8.3) for retaining purposes.
9.6 Apply small quantity of grease to the chuck (8.2) and insert the shaft. Using the keys, screw the chuck
clockwise up to the stop as described above and tighten slightly.
9.7 Previously, chuck and shaft need to be carefully cleaned to avoid radial deviation.
9.8 Attach the milling spindle to the motor and tighten the union nut (8.1).
9.9 Insert milling spindle into the holding mechanism and tighten the locking screw (5.6).
