Theory of operation
The 3-position (FNR) Electric 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.
