MAINTENANCE
Replacing the cutting unit’s belts
Belt replacement on BioClip 103
There are two versions of BioClip 103. Version 1
has a single toothed belt and version 2 has two
belts. 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 34.
2. Remove the attachment frame, see “Removing
the attachment frame”.
3. Tilt the height adjustment arm (E) forwards.
Unscrew the front bolt from the parallel strut (F)
and tilt the strut backwards.
4. Undo the two screws that hold the protective
cover and lift off the cover.
Useful hint: Mark the positions of the blades on
each belt using a felt-tip pen.
5. Version 1:
Unscrew the three screws 1/2 - 1 turn. Press
the sides of the belt together to give maximum
slack and tighten one of the screws. Replace
the belt and tension it as shown (see decal on
cover). Set the blades at 90° to each other and
undo the screw again. The spring will set 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 screws to a torque of 45 Nm.
5. 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.
