Adjust the clamping force of the t-piece
To ensure a proper sectioning result, the knife holder base
onto the base plate (→ "Fig. 26-1").
The clamping is carried out using an eccentric lever (→ "Fig. 26-2"). The clamping force is adjusted with
the setscrew
(→ "Fig. 26-4")
that the clamping lever can be rotated to the stop with constantly increasing resistance.
To set the clamping distance from the eccentric bolt to approx. 200 °, do the following steps.
1. Remove the knife holder base from the base plate.
2. Adjust by screwing clockwise or counterclockwise the countersunk screw
clamping piece in the base using the Allen key No. 4, so that the eccentric lever
