Floor Level and Inner Roll Stop Adjustments
Achieving proper floor level posi-
tioning of the platform and inner
roll stop requires a combination
of Floor Level switch adjustment
and inner roll stop cam adjust-
ment. Both are factory set, but
floor level positioning must be
inspected during installation
procedures (will vary per vehicle
application).
Floor Level Requirements:
When the lift is positioned at
floor level (raised fully), the
bottom of the platform must be
above floor level (threshold mat)
The Floor Level switch stops upward travel
of the platform during the Up function (ac-
tivated by the torque tube-mounted Floor
Level cam).

1. Position the bottom of the lift platform 1"
above floor level (threshold mat) using
the manual hand pump. See Figure A.
2. Loosen the clamp securing the torque
tube-mounted Floor Level cam. See
Photo A. Rotate the cam until the Floor
Level switch is activated (cam depress-
es switch). Tighten the clamp securing
31637-005.ai
the cam.
Hydraulic pressure may affect platform
height slightly. Fine tuning adjustment
(tweaking) of the Floor Level switch
(cam) may be required.
3. Using the control pendant, check floor
level position by lowering the platform
to stow level and then pressing the UP
button until the platform raises fully
(stops).
If the inner roll stop rests solidly on
vehicle floor with 7° maximum angle
(relative to the platform), move to page
10 and check the usable platform length
as outlined.
and the inner roll stop must rest
solidly on vehicle floor with 7°
maximum angle (relative to the
platform).

PACK
Ensure the lift is positioned and
secured as specified on the
Quick Reference Installation
Sheet supplied with the lift.
Adjust the Floor Level switch
first (detailed below). If the 7°
requirement above is not met,
adjust the inner roll stop cam
31637-005.ai
as detailed in Cam Adjustment
(adjust cam only if necessary).
Floor Level Switch Adjustment
Do not adjust the inner roll stop
linkage rod (see Photo H on page
10). The linkage rod should be
adjusted to increase usable plat-
form length only (following all
other procedures).
