Operation
Lifter

(1) Never adjust!
(2) Cylinder-shaft movement height
adjustment
(3) Pressure spring
ADVICE
If the length of the rods (1) to the potentiometers on the lifting unit is adjusted, the
electronic system will receive incorrect signals and will therefore no longer be func-
tional.
There are pressure springs (3) left and right beside this spindle on both sides of the
lifting unit, these may put an additional load on the depth-control shaft. In case of
need, for instance for very wet ground, this spring pressure may be reduced down to
zero (turn back the lock nut).
