MAINTENANCE
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. Checking the tyre pressure 60 kPa (0.6 kp/cm
2
).
2. The cutting unit should be lowered on a level
surface.
3. The height setting lever should be set for the
lowest cutting height.
NOTE!
The parallelism and height must be
adjusted again when changing the
cutting unit.
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 2-4 mm higher than the
front edge of the unit.
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.
