Bridging Microswitch:
The
bridging microswitch is located
at the bottom of the left (rear)
vertical arm. See Photos A
and B. An adjustment screw is
built into the platform stop
block.
The bridging microswitch will
be deactivated if the outboard
end of the platform contacts
the unloading surface before
the inboard end while the
DOWN switch is pressed.
The deactivated bridging
microswitch interrupts power to
the DOWN switch circuit and
stops the down travel of the
platform (while allowing the roll
stop to deploy).

Unfold/Down and Up/Fold Microswitches:
The Unfold/Down and Up/Fold mi-
croswitches (limit switches) are located
between the pump module and the tower.
Adjustment:
Use a 7/16" socket wrench to
turn the two 1/4"-20 x 3" hex bolts to reposi-
tion the limit switches. Adjust these mi-
croswitches as outlined at right and on
Microswitch Adjustment Instructions decal

Floor Level Guideline Adjustments:
The
Unfold/Down and Up/Fold microswitches
control platform and bridge plate positioning
(fixed bidge plates and automatic inboard
roll stops). Ensure floor level adjustments
are correct as outlined on pages 38 and 39.
Platform Angle Adjustments:
Check
platform angle as outlined on pages 26 and
27 when adjusting bridge plate positioning.
Turn adjustment bolt counter-
clockwise to stop platform unfold
function sooner. Turn adjustment
bolt clockwise to allow platform
to unfold further.
Unfold/Down Microswitch:
Up/Fold Microswitch:
Turn adjustment bolt clockwise to
stop raise function sooner. Turn
adjustment bolt counterclockwise
to allow platform to raise further.
