Adjustment
Important – knob unscrewed
Roller adjustment should always be
performed with the knob unscrewed
to its end position. Undo the lock-
nuts.
The best adjustment check is obtai-
ned if the lock-nuts are tightened
somewhat before adjustment is
carried out.
Rough adjustment
Rotate the blade by hand and tighten
the adjustment screws until the rol-
lers rotate.
Fine adjustment
Fine-tune the adjustment to a posi-

Tighten the knob
End by tightening the knob that ten-
sions the blade against the drive disc.
Correct adjustment
Correctly adjusted rollers are very important to
the machine’s function and in order to reduce
wear.
Correct adjustment means that the rollers
should be in uniform contact with the blade
without any play or clearance.
If the rollers fit too tightly, the result is in-
creased wear and blade deformation, which
can even lead to blade breakage.
If the rollers are not fitted tightly enough,
the blade is not guided properly, which in the
worst-case scenario can lead to the blade jum-
ping out of its groove.
Function
The support rollers are fitted on levers in the
support roller shroud. The adjustment screws
(A) are used to alter the position of the lever.
The lock-nuts (B) lock the lever in position.

The rollers must always be adjusted when:
– switching to a new blade
– switching to another used blade
– replacing engagement or support rollers
Always check adjustment when the support roller shroud has
been removed and refitted.
