Adjusting the Knife Holder with Anti-roll Guide You can adjust the height of the anti-roll guide system using the knurled nut (1):

•If you turn the nut counterclockwise, the anti- roll guide system moves toward the blade.

•If you turn the nut clockwise, the anti-roll guide system moves away from the blade.

IIand anti-roll guide as shown in Fig. III.

Generally, we recommend pre-adjusting the anti-roll guide system at a high sec- tion thickness (e.g. 10μm). Start from there and work your way down to the desired section thickness in small increments, readjusting the anti-roll guide system at each increment using the knurled nut.
