Maintenance
Removing the cutting unit
1 Carry out points 1-6 to put the cutting unit in the service
position, see Service position for the cutting unit.
2 Lower the cutting unit.
3 Open the unit catch.
4 Pull out the cutting unit.
Checking and adjustment of the
cutting unit’s ground pressure
To achieve the best cutting results the cutting unit should
follow the underlying surface without pressing too hard
against it.
Pressure is adjusted using a screw and spring on each side
of the Rider.
1 Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.
2 Place the machine on a flat surface.
3 Put the lifting lever in the mowing position.
4 Place a set of bathroom scales under the cutting unit’s
frame (front edge) so that it rests on the scales. If
necessary a block can be placed between the frame and
scales so that the support wheels do not bear any weight.
5 Adjust the unit’s ground pressure by screwing in or out the
adjusting screws located behind the front wheels on both
sides. The ground pressure should be between 12 and 15
kg (26.5-33 lb).
Checking the cutting unit’s
parallelism
Check the cutting unit’s parallelism as follows:
1 Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.
2 Place the machine on a flat surface.
3 Put the lifting lever in the mowing position.
4 Measure the distance between the ground and the front
and rear edges of the cutting unit hood. The cutting unit
should have a slight slant, with the rear edge 2-4 mm (1/
8”) higher than the front edge.

WARNING! Wear protective glasses when
dismantling the cutting unit. The spring
