Assignment of flow rate, vehicles with
dual-circuit hydraulic system
General notes
The flow rate is created by two gear pumps.
The flow rate for circuit I is 32 l/min and for
circuit II, 55 l/min. The stated flow rates apply
to a rated engine speed of 2200 rpm. You can
change the flow rate amount for the individual
circuits. To do so, however, all flow rates must
be turned off beforehand.
Switching the flow rate
Using button L, you can switch the flow
rates between working hydraulics circuit I and
circuit II.
