Danger of accident
Do not try to clamp larger workpieces. The chucking power is then too low and the jaws
can detach themselves.
Mounting of turning jaws:
The jaws and guides are numbered from 1-3. Open the chuck by means of the chuck key until the
jaws loosen. (order: 3, 2, 1 bzw. 4, 3, 2, 1).
Now, take the inner jaws beginning with the number 1 and put this in the guide number 1. Push the
jaw number 1 in the direction of the centre point of the chuck and at the same time turn the chuck
key (direction "tighten"). When the transverse spiral has taken hold of number 1, number 2 must be
put in the guide provided. The same now happens to number 2 as to number 1. Proceed with num-
ber 3 and number 4 in the same way. Subsequently, examine the position of the jaws.
Mounting of drilling jaws:
If, afterwards, you again want to work with outer jaws, the process repeats itself in the same order
(first jaw 1, then 2, then 3, then 4).

Tool holder with conical sleeve
Only those workpieces may be used which accord to the nominal diameter of the collet
chuck.
Mounting of the tool holder:
When working with the collet chuck, the concentric chuck must be removed from the workspindle.
In order to do this, loosen the three tightening screws by means of the Allan key SW6 included in
the accessories. Now, the chuck can be liftet from the concentric flange of the workspindle and the
closer can be inserted into the workspindle by gently pushing it.
Subsequently, insert the required collet chuck into the closer and by means of the hand draw-in
tube (which is fed in through the hollow workspindle from the gear side) draw the collet chuck into
the closer.
