In the event of electrical failure, the jack leg(s) may be retracted manually by following the procedure below.
1. The individual cartridge valves are clustered together on the side of the pump manifold.
Locate the screws on the appropriate cartridge valve(s).
Using a 5/32" Allen wrench, turn the screw(s) clockwise until all the way in.
Note: The normal operating position of the screw in the cartridge valve is the
counter-clockwise ‘out’ position. The only time the valve should be shifted manually
is when attempting to operate jack(s) via manual override.
2. Remove the plastic cap from the top of the motor and disconnect the power cables.
3. Attach a 1/2" socket to the motor's coupler and drive it with a drill, ratchet or similar device.
4. To retract your jack(s) run the drill in the counter-clockwise direction.
5. To extend your jack(s), run the drill in the clockwise direction.
6. When manual override is complete, return the cartridge valve(s) to the normal positions.
Reinstall power cables and plastic cap on motor.
