Set a clearance of 53.5 mm between edge 5 of the clamping plate
and the outside of the roller 4.

Tilt the machine head up.
–
Slowly turn the hand crank farther until the roller 4 is close in front
of the knife drive curve 3.
–
During the continued turning the roller 4 should not hit in front of
the tip of the knife drive curve 3.
It should roll off of the inside of the curve and be only lightly
operated by the curve beginning.
If this is not the case suitably correct the position of the operating
lever 2 before turning farther.
–
Continue to turn the hand crank until roller 4 reaches the end of
the drive curve.
In this position it must be possible to manually move the movable
knife 6 slightly to the left.
ATTENTION !
If the movable knife 6 cannot be moved farther in the cutting direction
there is a danger of breakage through blockage.
–
Set the safety clearance by adjusting the roller 4:
in arrow direction + = greater swing to the left
in arrow direction - = less swing to the left
