Belt replacement on BioClip 103 and Combi 103
There are two versions of BioClip 103. Version 1
has one toothed belt and version 2 has two. Combi
103 is only available with a tooth belt. 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.
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.
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.
WARNING!
Protect your hands by wearing
gloves when working with the
blades.
4. Version 1 and Combi 103:
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/32 lbft.
