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. For directional
valves, rotate the red knob until it 'snaps' back to the normal position.
In the event of electrical failure, the jack leg(s) may be retracted manually by following the
procedure.
1. The individual cartridge valves are clustered together on the side of the pump manifold.
(They are labeled 1 through 4 on the diagram on the next page). 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-clock-
wise 'out' position. The only time the valve should be shifted manually is when attempting to
operate jack(s) via manual override.
2. Locate the red knurled knob on the directional valve** DV2. This valve will be on the
opposite side of the manifold from the cluster of cartridge valves. Pull the red knob out
and turn 1/4 turn. The knob will remain in the 'out' position.
** NOTE: The normal operating position of the red knob on the directional valve(s) is the 'in'
position. The only time the valve should be shifted manually is when attempting to operate
jack(s) via manual override.
3. To retract, locate the red knurled knob on the directional valve**DV1. This valve will be
on the adjacent side of the manifold to the cluster of cartridge valves. Pull the red knob
out and turn 1/4 turn. The knob will remain in the 'out' position.
4. Remove the black plastic cap from the top of the motor. Use a small flat head
screwdriver. Place the drill with the 7/16" (11mm) hex bit on the manual override shaft
located at the top of the motor. Run drill in a clockwise direction at 2000 r.p.m.
(minimum). The jack leg(s) will retract.
5. When retraction is complete, return the cartridge valve(s) and the directional valves
DV1 & DV2 to the normal positions. Reinstall black plastic cap on the motor.
