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. BioClip 103 Version 1 and 2

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/32 lbft.
