Manual Overide for Bi Rotational Pumps

Pump #s 2390, 2532, 2542

Your hydraulic pump is equipped with a Bi Rotational motor.
You will use a 2000 r.p.m. drill and a 7/16" socket or ¼" Allen Driver.

Care must be taken to ensure neither the drill nor the socket contact any wires or
hydraulic hoses while in use.
To operate your jack(s) using the manual override (with bi-rotational motor)
The individual cartridge valves are clustered together on the side of the pump manifold. They are
labeled 1 thru 4. Locate the screws on the appropriate cartridge valve(s). Using a small flat blade
screwdriver or 1/8" Allen wrench,(depending on valve type) turn the screw(s) clockwise until seated
in.
The pump may or may not have a DV-2 valve on the opposite side of the manifold. If it is the Allen
type, turn the screw clockwise until seated in. If it has a red knob, pull out on it and turn ¼ turn, it
should stay in the out position.
Remove the black plastic cap from the end of the motor. Use a small flat head screwdriver. Place the
drill with the 7/16" socket or ¼ inch Allen on the manual override shaft located at the end of the
motor.
To retract your jack(s) run the drill in the counter-clockwise direction.
To extend your jack(s), run the drill in the clockwise direction.
When manual override is complete, return the cartridge valve(s) to the normal position(s). Reinstall
black plastic cap on motor.
Caution: Following manual override operation, failure to return all valves to normal position may
result in one or more jack legs drifting down from their retracted (stowed) position. For cartridge
valves, rotate the center screw fully counter-clockwise.
*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.
