Only certain control options for the S42 pump utilize the 3 Position Control (FNR). Please refer to the
pump's nomenclature to determine if the pump is equipped with the proper option. The nomenclature
can be found on the pump's nametag. For nomenclature details, refer to S42 Axial Piston Pumps Technical
Information, 11022637.

Theory of operation
The 3 Position Control (FNR) control uses an electric input signal to switch the pump to a full stroke
position.

Warning
Unintended vehicle or machine movement hazard. The loss of hydrostatic drive line power, in any mode
of operation (forward, neutral, or reverse) may cause the system to lose hydrostatic braking capacity. You
must provide a braking system, redundant to the hydrostatic transmission, sufficient to stop and hold the
vehicle or machine in the event of hydrostatic drive power loss.
