Removing the cutting unit

!
1 Carry out points 1-9 to put the cutting unit in the service
position, see Service position for the cutting unit.
2 Remove the bolt (3) and lift off 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 kp/cm
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.
WARNING! Wear protective glasses when
dismantling the cutting unit. The spring
which tensions up the belt may break and
cause personal injury.
