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).

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.
Bridging Microswitch Adjustment
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.
