Setting the parallelism and height for the cutting unit with rear ejector and BioClip unit
The base unit is adjusted at the factory. When one of the attachments is fitted, the parallelism and height need to be adjusted.
Starting point:
1.Check the tyre air pressure, which should be 60 kPa (0.6 bar).
2.The cutting unit should be lowered on a level surface.
3.The height setting lever should be set for the lowest cutting height.
Parallelism
Always start by adjusting the parallelism.
1.Loosen the two nuts on the arm.
2.Measure the distance between the ground and the front edge of the unit, at the front and rear of the hood.
3.Place a wrench on the bevelled section in the centre of the arm and turn so that the rear edge of the cutting unit sits
4.Check the measurements.
5.Now tighten the two nuts on the arm.
Cutting height
1.Loosen the nuts on the height setting arm.
2.Adjust so that the distance between the stop for the lowest height setting and the protective frame is 5 mm.
3.Tighten the nuts.
4.Check that the parallelism has not changed. If it has changed, the parallelism must be readjusted again.
5.Check and, if necessary, adjust the cutting unit’s ground pressure as described in the next section.
6.Fit the nose.
IMPORTANT INFORMATION
The parallelism and height must be adjusted again when changing the cutting unit.
