DESCRIPTION
Lighting Control
Switch
The ON/OFF switch controls the stairway
courtesy lights and the A-frame floodlight.
Stairway Control
Handle
The handle controls the cylinder that raises the
upper stairs/platform. Placing the handle in
the UP position raises the stairway. Placing the
handle in the DOWN position releases the stairs
cylinder lock valve and retracts the cylinder.
This handle is used along with the stair ratchet
release handle to lower the stairway. The
stairway cylinder cannot retract unless the
ratchet is first released manually.
A-frame Control
Handle
The handle controls the cylinder that raises the
A-frame. Placing the handle in the UP position
raises the A-frame. Placing the handle in the
DOWN position releases the A-frame lock valve
and retracts the cylinder.
This handle is used along with the A-frame
ratchet release handle to lower the A-frame. The
A-frame cannot retract unless the ratchet is first
released manually.
Stabilizer Control
Handle
The handle controls the four stabilizer cylinders.
Placing the handle in the DOWN position extends
(lowers) the stabilizers. Placing the handle in the
UP position retracts (raises) the stabilizers.
NOTE:
A cord reel near the base of
the stairway enables the wiring
cord for the upper stairs and
platform lights to extend and
retract as the stairway is raised
and lowered.
