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 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.

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.
