A - Return Line

B - Pressure Line

C - Load Sense Line

D - Control Valve

E - Vacuum Motor

F - Raise/Lower Cylinder

G - Motor Case Drain Line

H - Second Motor

I - Marker

J - Fold

K - Power Beyond Ports

L - Extend Coupler Line

M - Retract Coupler Line

N - Controlled Flow Line

O - Special Return Hose Tip

In this application, vacuum motor (E) is being operated from power beyond which requires a load sense connection (C) to signal hydraulic pump for operation.

The second motor (H) is equipped with motor case drain line (G). Pressure oil comes from retract port on SCV and return oil is routed to extend port. When motor return oil is routed to an SCV, a special return hose tip (O) is required to prevent high-pressure oil from moving back toward the motor and possibly damaging the seals. When motor is shut off, SCV lever is moved to float position to allow motor to coast to a stop. Moving lever to neutral will cause motor to stop abruptly and may damage seals when return oil is routed through an SCV.
