Following manual override operation, failure to return all valves to normal position may
result in slideout(s) creeping 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 slideout(s) may be retracted manually by following the
procedure below.
1. Locate the hydraulic pump in the front driver’s side compartment bay.
2. The individual cartridge valves are clustered together on the side of the pump
manifold. (They are labeled 5 through 8 on the diagram on the next page). Refer to the
“Hose Color Identification” to select the proper cartridge valve. 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(s) in the cartridge valve is the
counter-clockwise “OUT” position. The only time the valves should be shifted manually is when
attempting to operate the slideout(s) via manual override.
3. 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 ¼ 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 the
slideout(s) via manual override.
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 corresponding slideout(s) will retract.
