Emergency Retraction Procedure
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.
In the event of electrical failure, the jack leg(s) may be retracted manually by following the procedure below.
Manual Override for MTE Bi-Rotational* Style Pumps (These can be identified by the presence of 2 motor
solenoids and 2 motor leads)
1. 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, 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 black plastic cap from the top of the motor. Use a small flat head screwdriver.
Place the drill with the 7/16" ( 1 1 mm) socket on the manual override shaft located at the
top of the motor.
3. To retract your jack(s) run the drill in the counter-clockwise direction.
4. To extend your jack(s), run the drill in the clockwise direction.
5. When manual override is complete, return the cartridge valve(s) to the normal positions.
Reinstall black plastic cap on motor.
