2-12-5 READJUSTING KNIFE CARRIERS N,
E AND C
Frequent use of the clamping levers can lead to the
fact that the knife carriers cannot be clamped
optimally anymore. If the necessary readjustments
are not carried out, it might even be possible that
the knife carriers cannot be clamped anymore.
If possible, the clamping lever should be in a 45°-
position towards the front (fig. 19).
Fig. 19
If the clamping lever is in an unfavourable
clamping position, i.e. not in a 45°-position,
remove knife carrier. Loosen the set screw (fig.
20.1) on the bottom of the knife carrier. Insert a
pin into one of the holes (fig. 20.2) that can be
seen in the brass screw and turn the brass screw.
If the clamping position of the lever should be
moved towards the front, turn the brass screw (fig.
20.2) in a clockwise direction. If the clamping
position of the lever should be moved towards the
back, turn the brass screw (fig. 20.2) in a counter-
clockwise direction. Before putting on the knife
carrier again, tighten set screw (fig. 20.1).
Then put the knife carrier on the dovetail guide
and check the clamping position of the clamping
lever. If necessary, repeat above-mentioned
process.

2-12-6 READJUSTING KNIFE CARRIER S
Readjusting the clamping lever (fig. 18.2) of the
knife carrier S can also become necessary.
If the clamping lever is in an unfavourable
position, i.e. not in a 45°-position, remove the
knife carrier. Loosen or tighten the set screw on
the bottom of the knife carrier to change the
clamping position of the lever.
If the clamping position of the lever should be
moved towards the front, turn the set screw in a
clockwise direction. If the clamping position of the
lever should be moved towards the back, turn the
set screw counter-clockwise.
Then slide the knife carrier on the dovetail guide
and check the clamping position of the lever. If
necessary, repeat above-mentioned process.
