MAINTENANCE

IMPORTANT INFORMATION

The blades on a BioClip deck should be set at 90 degrees to each other. In all other cases the blades can collide and cause serious damage to the cutting unit.

4.Assembly: First fit the lower belt and then the upper belt.

Ensure the blades are positioned as set out in the diagram, at 90 degrees to each other, otherwise the belts must be adjusted. When the blade bearings are loose the belts can be moved around to the next tooth.

Tighten the nuts enough so that the bearings rest against the cutting hood but still can be moved.

Tension the belt by turning the eccentric adjuster on top of the cutting hood. Tighten the nut.

Tighten all nuts on the blade bearings.

5.When the belt can be moved 7 mm inwards using a force of 10 N the belt is adjusted correctly.

Fit the protective cover over the belts and replace the parallelism arm.

Belt replacement on cutting unit’s with side or rear ejectors

Cutting units with side or rear ejectors are powered by one V-belt. Proceed as follows to replace the V-belt:

1.Loosen the unit frame (1), the bolt on the parallelism arm (2) and the two bolts on the hood (3). Lift off the cutting unit’s hood.

2.Loosen the spring that tensions the V-belt and pry off the belt.

To fit a new belt, follow the instructions above in the reverse order.
