By-Pass Valve

1. The By-pass valve controls the pressure at which the leveling system operates. The
Level Best system operates at a pressure of 1500 to 1800 pounds per square inch. The
By-pass valve is located on the side of the pump motor mounting block (Figure 4b.)
2. Pump motor runs but leveling legs do not operate. Check the
reservoir fluid level, refer to Segment 1A: Fluid Level.
3. Legs will retract but not extend. Check 4-Way valve operation
refer to Segment 5: Solenoid Valves.
4. Check the system pressure by installing a gauge in the 'P' Port
on the manifold. The gauge will read the by-pass pressure when
the jack is at full extension/retraction. Adjust the bypass valve if
inadequate pressure is recorded (Figure 4c.)
