LEFT RETRACT – ELECTRICAL
System Response
1. By activating the WING function
on the left side of the cab
control, the control sends a
signal to the Plow Module to
complete the ground path for
the electrical circuit, activating
the motor relay and solenoid
cartridge valves S1, S4 & S6.
The wing mode toggles between
extend and retract.
NOTE: See the System Overview –
Controls Section for operation
information.

2. Hydraulic fluid from the pump
flows through activated S4 into
the rod end of the DS ram,
causing it to retract.
3. The retracting DS ram pushes
the hydraulic fluid out of its base
end, through activated S6 & S1
and back to the reservoir.
NOTE: Battery voltage is supplied
to the Plow Module, the motor
relay and the 11 solenoid coils
when the snowplow is connected
to the vehicle.
