Make sure that the tools on the upper and lower delivery shaft mate properly.
Perforating knives and scoring disks which
work against a groove in the mating part (4)
must run exactly in the center of the groove.
If the setting is not precise, the paper may be
cut completely or the tools may wear pre-
maturely.

Perforating and slitting knives (5) which
work against a mating knife (6) (scissor
action) must be positioned as close as
possible.
Do not use the rounded off edge of the lower
slitting knife (7) for slitting or perforating.

When the tools are not needed, they can still remain
on the delivery shafts.
Just loosen the Allen screws and move them apart
so that the upper and lower tool no longer touch
each other (8).
Travel Limit of the
Lower Delivery
Shaft
The lower delivery shaft is spring-loaded.
The resulting travel of the delivery shaft can be adjusted by loosening and tightening
two adjusting screws (9).
In addition to setting the screws, two pressure springs
(10) have been installed between the bearing arm and
the stop. They serve as dampers for the lower
delivery shaft.

The travel should be as small as possible to
achieve a precise scoring, perforation or a
straight cut.
The exact position of the two screws (9)
can be determined by running a few
sample sheets.
When working without any perforating-,
scoring- or slitting tool, screw both screws
all the way out for maximum travel.
