Adjusting the Lever Housing
The machine and cutting unit shall be on a
flat surface.
1.
Pro 18 Remove the plastic cover
between the seat and the lever housing.
PF 21 Remove the plastic cover from the
hydraulic valve block.
2.
Set the adjustment screws (1) and (2) on
the drive disc so that the ends of the
adjustment screws are even with the
outer edges of their lock nuts.
3.
If the screw for the chain segment or the
microswitch has been removed, make
sure that the microswitch is not screwed
into place so that it is damaged when the
unit is lifted. It can be loosened if
needed, and the engine started with
bypassed safety circuitry for the next
step.
4.
PF 21 Lift the unit fully with the hydraulic
lifting lever.
Hold the lever still for 0.5-1 second to
ensure that the hydraulic cylinder
reaches its end position.
Pro 18 Hold up the unit with the
mechanical lifting lever as high as
possible.
5.
Make sure that the catch to the hydraulic
lift lever has about 2 mm (1/16") of play
in relation to its grip on the frame tubing
when the lever is in its upper position.
Adjust as needed with adjustment screw
(1) or (2) on the drive disc.
