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 37.

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.
