Standard checking
The adjustment of the cutting position has to be done as described
hereafter.

support 2.
Screw on gauge X (part no. 0767 290030) and press the axle of the
–
thread pulling knife support 2 against the gauge X from below.

Tighten the two adjusting rings 1 on the axle of the thread pulling
knife support 2.
