The clamping blades must be replaced when worn out. To do this:

Undo the 3 retaining screws and remove the worn clamping blades (A, B and C) .
2. Install the new blades, check their positioning according to the drawing below, and secure them

5.4. Material presence check
Depending on the sequence of the bar feed system and in order to
prevent damages to material, a control system verifies that there is
no material in the collet. Bar presence check consists of the optical
cell (
A ) located in front of the vise ( B ).
The check is carried out as follows:

the optical switch first determinates if the remnant has been
extracted out of the spindle.

the optical switch then determinates if the remnant has been
properly ejected out of the bar feeder.
This control takes place after opening of the channel.
