The pneumatic front rest works as follows:
1. Closed position, holding and guiding the bar stock

The guiding elements are adapted to the bar stock diameter (bar diameter + 1 mm). See section 2.
GUIDING ELEMENTS in this chapter.
Setting procedure:
1. Mount the guiding elements with the inner diameter adapted to the bar stock to load.
2. In manual mode, close the guiding zone, and move the pusher to the air blast position.
3. If the pusher does not reach the air blast position because it hits the guiding elements, open the front
rest by activating the front rest in manual mode (Parameters →User (F0) → Functions (F3) →
PgDn/Down, activate function (F0). Now you can easily open and close the front rest by pressing “open
channel” or “close channel” keys to set up the screw (F on page 7-17).
