Bale density
adjustment
Increases in pressure are prohibited
It is prohibited to increase the maximum working pressure setting for
the bale density on the hydraulic block. Attempting to do so will render
the warranty invalid and exempt the manufacturer from all liability. Da-
mage may be caused to the implement.
The bale density depends on the type of crop which must be formed
into bales and also the set hydraulic pressure. The hydraulic pressure
is obtained by closing the rear flap using the tractor's control device.
The hydraulic pressure can be read using the pressure gauge. A ma-
ximum hydraulic pressure of 165 bar can be set.

The higher the hydraulic pressure, the denser and heavier the bale will
be.
The prescribed pressure values in the table are standard values. The
values actually required depend on the type of crop. These values
may therefore vary.

If the set pressure is not achieved, it is possible that too little crop was
gathered.
> Switch the tractor on.
> Open the rear flap via the control device.
> Switch off the tractor and secure it.
> Turn the handwheel on the hydraulic manifold to the right to increa-
se the bale density.
> Turn the handwheel on the hydraulic manifold to the left to reduce
the bale density.
> Switch the tractor on.
> Close the rear flap via the control device.
> Leave the control device lever in the position for closing the rear
flap for approximately 3 seconds to allow the pressure to build up
for the default bale density.
> Check the pressure with the pressure gauge.
The set hydraulic pressure is displayed on the pressure gauge.
