Restraining section of counterbalance valves open,
controlling fluid flow out of jacking cylinders. Fluid then exits
counterbalance valves and flows out of upper accessory
valve before returning to tank through return manifold. If
more power is needed to extend jacks, engine speed can be
increased with remote engine speed switch in remote start
junction box on right side of rotating bed.
When power button or jacking switch is moved to off position,
the PC sends a 0 volt output to shift spool of solenoid valves
HS-25 and HS-27 to center position.
