IMPORTANT INFORMATION
The blades on a BioClip unit should be set
at 90 degrees to each other. In all other
cases the blades can collide and cause
serious damage to the cutting unit.
5. Ensure the blades are positioned as set out in
the diagram, at 90 degrees to each other,
otherwise the belt must be adjusted. When the
blade bearings are loose the belt 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.
6. When the belt can be moved 8 mm (5/16")
inwards using a force of 7 N (1.5 lb) the belt is
adjusted correctly.
7. Fit the protective cover over the belts and
replace the parall strut.
