Adjustment of hydraulic weight transfer system
The hydraulic weight transfer system distributes the weight evenly between
all the machine's sections.
The control lever connected to the outlet (marked: red) is then set to
the float position. The floating setting is required to achieve hydrau-
lic weight transfer, allowing the sections to move independently and
protecting the machine's key components. The pressure will remain
indicated on the manometer after float position has been adopted.

Once the roller is fully extended and the transport wheels are off the ground,
the extend/retract cylinders are depressurised (marked: red), the cylinder con-
trol lever is then moved in the opposite direction.
This is indicated after
a short delay
by a deflection of the
manometer. The pres-
sure is increased to
approx. 15 bar (B).
Some of the weight
from the machine's
centre is thus trans-
ferred to the side sec-
tions.
The pressure for hydraulic weight transfer may need adjustment. It may also
be necessary to adjust pressure according to soil conditions.
The accumulator precharge pressure (air pressure) is pre-set ex works, but
must be adjusted according to the actual type and character of the soil. This
must be done in consultation with a licensed Dal-Bo dealer.
Check all the accumulators on the machine at least once a year for leaks
and to ensure that the precharge pressure is set correctly. Contact an
authorized Dal-Bo dealer for more information.
