Replacing the cutting unit belts
Belt change on BioClip 103
There are two versions of BioClip 103. Version 1
has one toothed belt and version 2 has two. The
toothed belts drive the blades and synchronise their
rotation. The belts are located under a cover on top
of the cutting unit.
1. Remove the cutting unit, see page 30.
2. Remove the front bolt from the parallel strut and
tip the strut backwards. Push the height
adjustment strut forwards.
3. Loosen the two bolts holding the protective hood
and then lift off the hood.
Useful hint: Mark the positions of the blades on
the respective pulley using a felt-tip pen.
WARNING!
Wear gloves to protect your
hands when working with the
blades.

4. Version 2:
Loosen the nuts on the eccentric plate and turn
this away.
Loosen the four nuts (see diagram) holding the
outer blade bearing enough so that the bearing
can be moved.
Slide the blade bearing in towards the centre
bearing and pry off the upper belt.
Repeat the procedure for the lower belt.
4. Version 1:
Loosen the three bolts 1/2 - 1 turn. Press the
sides of the belt together to give maximum slack
and tighten one of the bolts. Replace the belt
and tighten as shown (see decal on cover). Set
the blades at 90º to each other and loosen the
bolt again. The spring ensures the correct belt
tension. Check the positions of the blades again
and adjust if necessary by repositioning the belt
on the teeth. Tighten the three bolts to 45 Nm.
