Belt replacement on Cutting Unit 120 with rear
ejection
On cutting units with rear ejection the blades are
driven by a V-belt. Proceed as follows to replace
the V-belt:
1. Loosen the unit frame (1), the bolt on the
parallelism arm (2) and the two bolts on the
hood (3). Lift off the cutting unit’s hood.
IMPORTANT INFORMATION
On BioClip 103 units the belts must be set
at 90° to each other. In all other cases the
blades can collide and cause serious
damage to the cutting unit.
6. Version 2:
Assembly: First fit the lower belt and then the
upper belt.
Ensure the blades are positioned as set out in
the diagram, at 90 degrees to each other,
otherwise the belts must be adjusted. When the
blade bearings are loose the belts can be
moved around to the next tooth.
Tighten the nuts enough so that the bearings
rest against the cutting hood but still can be
moved.
Tension the belt by turning the eccentric adjuster
on top of the cutting hood. Tighten the nut.
Tighten all nuts on the blade bearings.
7. Version 2:
When the belt can be moved 7 mm inwards using
a force of 10 N the belt is adjusted correctly.
8. Version 1 and 2:
Fit the cover over the belts and refit the parallel
strut and attachment frame.
