Bale density
adjustment
I ncreases in pressure are prohibited
It i s prohi bited to i ncrease the maximum worki ng pressure setting for
the bale density on the hydraulic block. Attem pting to do s o will render
the warranty invalid and exempt the manufacturer from all liability. Da-
mage may be caused to the implement.
The bal e densit y depends on the t ype of crop w hi ch must be formed
into bales and also the set hydraulic pressure. The hydraulic pressure
i s obtained by cl osi ng the rear fl ap 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 heav ier the bale will
be.
The prescri bed pressure val ues 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 wi t h the pressure gauge.
The set hydraul i c pressure is di spl ayed on the pressure gauge.
