Adjustment of the hydraulic suspension of the pendle frames
The hydraulic suspension of the five middle pendle frames is designed to relieve rings and frames from
hard impacts and loads, which might occur during driving in fields from stones and undulations.
It may be necessary to readjust the pressure for the hydraulic weight distribution. Likewise, it may be
necessary to drive with more or less pressure, depending upon the soil conditions.
It is important to close the ball valve again when the desired pressure is achieved in
order not to unintentionally adjust the pressure while using other functions and
thereby risk damaging the machine.
Too much pressure
1.
The pressure is too high if the cylinder will not move. The frames may be overloaded.
2.
Reduce the pressure until the cylinder starts moving again.
Too little pressure
1.
The pressure is too low if the cylinder is unable to extend to its full stroke.
2.
Adjust the pressure until all five cylinders for the suspension are, at least, extended again.
It is recommended to operate with a working pressure of 90 bar!
But, driving should always be done according to conditions!

1.
Adjustment of the hydraulic suspension must
be performed with the roller unfolded and
resting on the surface, and before the
hydraulic weight distribution is pressurised
(this can also be performed with the machine
in the transport position).
2.
Cylinder (A) is mounted on the five middle pendle
frames and acts as a shock absorber to counter
impacts from rocks and other heavy impacts
during work.

3.
Connect the manometer (B) to the hydraulic
stone protection and this must be set to a
pressure of approx. 90 bar (the pressure may
need to be adjusted depending on driving
conditions).
4.
This is done by opening the ball valve (C) and
activating the hose marked with white, without
any switch being activated (white hose
→ no
buttons activated).
5.
The ball valve must be closed again
when the desired pressure is achieved.
