2
/8.5
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.
Adjusting the parallelism of the
cutting unit
1
Remove the front cover.
2
Undo the nuts on the lift strut.
3
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.

Tighten the nuts after adjustment.
5
On completion of the adjustment the unit’s parallelism
should be re-checked.
6
Fit the right-hand fender and the front hood.
Service position for the cutting unit

brake.
2
Set the cutting height control in the lowest position and lift
up the cutting unit.
3
Remove the front cover.
4
