Adjusting the Unit's Parallelism
and Cutting Height
The base machine is adjusted at the factory. When a new cutting unit is attached, you need to adjust the
parallelism and cutting height.
Starting position:
1. Check the air pressure in the tyres
60 kPa (0.6 bar).
2. The cutting unit shall be lowered onto
a flat surface.
3. The height adjustment lever shall be set
to the lowest cutting height.

Parallelism

Always start by adjusting the parallelism.
1. Loosen the two nuts on the stay.
2. Measure the distance between the
ground and the front and back edges
of the unit's cover.
3. Place a spanner over the bevel in the
middle of the stay and tighten so that the
cutting unit's rear edge is 2-4 mm higher
than its front.
4. Check the measurement.
5. Then tighten the two nuts on the stay.

Cutting Height

1. Loosen the nut on the height adjustment
stay.
2. Adjust so that the distance between the
stop for lowest height setting and the
protective frame is 5 mm.
3. Tighten the nut.
4. Recheck that the parallelism has not
changed. If so, the parallelism must be
readjusted.
5. Check and adjust if necessary the cutting
unit's ground pressure as described in
the next section.
6. Attach the nose cover.
IMPORTANT INFORMATION
When changing the cutting unit, you must
readjust the parallelism and cutting height.
