Brush Circuit
NOTE: Hydraulic flow and relief pressure for the Pro
Sweep 5200 are determined by the tow vehicle.
Hydraulic flow from the tow vehicle goes to the control
manifold (port P) through the hydraulic input hose.
When the sweeper brush motor is not engaged and the
lift cylinder is stationary, hydraulic flow from the vehicle
is directed by the un–energized demand solenoid valve
(S2) to return to the tow vehicle through control manifold
port T and the return to tank hose.
NOTE: The hopper must be lowered for the Pro Sweep
5200 brush to operate.

When the brush switch is pressed to engage, both the
demand (S2) and brush (S3) solenoid valves in the hy-
draulic control manifold are energized. The valve shift of
S2 prevents hydraulic flow return to the tow vehicle. The
valve shift of S3 allows oil flow out of control manifold
port MP and to the brush motor causing rotation of the
sweeper brush. Oil return from the brush motor is routed
to control manifold port MR, out control manifold port T
and returns to the tow vehicle.
