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 kp/cm
2
/8.5
PSI.
2
Place the machine on a flat surface.
3
Measure the distance between the ground and cutting
unit’s edge at the front of the cover.
The cutting unit should have a slight slant, with the rear edge
2-4 mm (1/8”) higher than the front edge.
Adjusting the parallelism of the
cutting unit
1
Check the air pressure in the tyres 60 kPa/0.6 kp/cm
2
/8.5
PSI.
2
Remove the front hood and right-hand fender.
3
Undo the nuts on the lift strut.
4
Screw out (extend) the stay to raise the rear edge of the
cover.
Screw in (shorten) the stay to lower the rear edge of the
cover.
5
Tighten the nuts against each other after adjustment.
6
On completion of the adjustment the unit’s parallelism
should be re-checked.
7
Fit the right-hand fender and the front hood.
Service position for the cutting unit
The cutting head can be placed in the service position to
provide easy access for cleaning, repairs and servicing. In the
service position the cutting unit is raised and locked in the
vertical position.
Placing in the service position
1
Position the machine on flat ground. Apply the parking
brake. Set the cutting height control in the lowest position
and lift up the cutting unit.
2
Remove the front hood by removing the pin.
3
Disengage the spring for the drive belt tensioning wheel.
4
Loosen on the cutting height stay and place in the holder.
!
WARNING! Wear protective glasses when
dismantling the cutting unit. The spring
which tensions up the belt may break and
cause personal injury.
