Bridging Microswitch Adjustment
Bridging Microswitch:
The bridging microswitch is
located at the bottom of the
right (front) vertical arm. See
Photos A and B. An adjust-
ment 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 mi-
croswitch interrupts power to
the DOWN switch circuit and
stops the down travel of the
platform (while allowing the
outer barrier to deploy).
Switch
Activation Lever
1. Position the platform at floor
level (or slightly below).
Ensure the platform is not
partially folded. From the
stowed position, press the
UNFOLD switch until the
pump stops running and the
platform comes to a full stop.
From below floor level, press
the UP switch until the pump
stops running and the platform
comes to a full stop.
2. Check both platform stop
blocks to ensure there is no
gap between the stop blocks
and the vertical arms. See
Photos B, C and D on page
7. A gap may indicate that the
platform is not fully unfolded or
the platform angle adjustment
bolts are not adjusted equally
on both sides.
3. Loosen the two jam nuts on
the bridging switch activation
screw (see Photo G). Tighten
the screw until the activation
lever is fully depressed. Verify
that there is no play in the
activation lever and tighten the
jam nuts.
4. Test lift for proper operation.
Bridging Microswitch Adjustment
Adjustment Guidelines:
Caution: This adjustment is
factory set and typically should
not require adjustment.
Before adjusting the bridging
microswitch:
• Adjust platform angle as
detailed on page 6.
• Adjust floor level position as
detailed on page 8.
• Ensure platform is in the fully
unfolded position.
• Ensure both stop blocks are
making full contact with vertical
arms (details on page 7).
Failure to follow these
guidelines will result in an
overtight adjustment that
will bend the adjustment
screw, break the bridging
switch and/or result in lift
operation failure.
