Floor Level And Inner Roll Stop Adjustments - Braun Under-Vehicle Lift NUVL855R Service Manual

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
1-1/2" 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 depresses
switch). Tighten the clamp securing 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 but-
ton until the platform raises fully (stops).
If the inner roll stop rests solidly on ve-
hicle floor with 7° maximum angle (rela-
tive 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).
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
as detailed in Cam Adjustment
(adjust cam only if necessary).

Linkage rod adjust-
ment may result in
lift damage.
Do not adjust the inner roll stop
linkage rod (see Photo G on page

adjusted to increase usable plat-
form length only (following all
other procedures).
