Floor Level and Inner Roll Stop Adjustments  
Ensure the lift is positioned and secured as speci-  
ed above (panels 1 and 2). Adjust the Floor  
Level switch rst (detailed below). Then, adjust  
the inner roll stop as detailed in the service manual  
(adjust only if necessary). The inner roll stop must  
rest properly on the vehicle oor for wheelchair  
entry and exit.  
Achieving proper oor level positioning of the  
platform and inner roll stop requires a combina-  
tion of Floor Level switch adjustment and inner  
roll stop adjustment. Both are factory set but  
must be inspected during installation procedures  
(will vary per vehicle application).

The operations listed below must be  
functionally veried.  
Floor Level Switch  
Floor Level Cam  
The Floor Level switch stops upward travel of  
the platform during the Up function (activated  
by the torque tube-mounted Floor Level cam).  
Position the lift platform 1" above oor level  
using the manual operation system (de-  
tailed on opposite side of this sheet). Loosen  
the clamp securing the torque tube-mounted  
Floor Level cam. Rotate the cam until the  
Floor Level switch is activated (cam depresses  
switch).  
Vehicle movement is prevented unless the lift  
door is closed, ensuring the lift is stowed.  
Lift operation shall be prevented unless the  
vehicle is stopped and vehicle movement is  
prevented.  
Platform movement is prohibited beyond  
the position where the inner roll stop is fully  
deployed (up).  
The platform will not fold/stow if occupied.  
The outer barrier will not raise if occupied.  
The inner roll stop will not raise if occupied.  
A visual and audible warning will activate if  
the threshold area is occupied when the plat-  
form is at least one inch below oor level.  
Note: Check the oor level position of the plat-  
form and the inner roll stop after powering the  
pump. Hydraulic pressure may affect platform  
height slightly. Fine tuning adjustment (tweak-  
ing) of the Floor Level switch may be required.  
Lift platform movement shall be interrupted  
unless the outer barrier is deployed (up).

Lift Operating Instructions  
Lift Operating Instructions  
Note: The instructions out-  
lined here are applicable for  
“Public-Use” NUVL lift mod-  
els equipped with dual  
folding handrails and a dual  
outer barrier system.  
Handrails and Dual Outer Barrier:  
The folding handrails and tall outer  
barrier are manually operated. The  
spring-loaded outer barrier (tall barrier)  
and the handrails rest on the platform  
when the lift is not in use. The outer  
barrier must be raised to the vertical  
position and the handrails must be  
lifted to the vertical position whenever  
a passenger is on the platform.  
OPEN DOOR(S) AND SECURE  
TO LOAD PASSENGER:  
Before lift operation, park the  
vehicle on a level surface, away  
from vehicular trafc. Place the  
vehicle transmission in “Park”  
and engage the parking brake.  
Open manual doors fully, being  
certain the doors are secured in  
the fully open position.  
Manually open door(s) fully and  
secure.  
1. Read Notes below! Load pas-  
senger onto platform and lock  
wheelchair brakes.  
WARNING  
TO DEPLOY PLATFORM:  
Whenever a  
passenger is on the  
platform, the:  
• Passenger must  
be positioned  
fully inside yellow  
boundaries  
• Wheelchair brakes  
must be locked  
• Inner roll stop and  
outer barrier must  
be up.  
Failure to do so may  
result in serious  
bodily injury and/or  
property damage.  
Note: Outer barrier must be fully  
unfolded (ramp position) until the  
entire wheelchair (or standee) has  
crossed the outer barrier.  
1. Stand clear and press the UP  
switch until the platform extends  
fully. Release switch.  
The tall outer barrier and the handrails  
must be folded down to the platform  
(horizontal) position before stowing  
the lift. The handrails fold down onto  
the outer barrier to secure the barrier  
in the horizontal position.  
It is the responsibility of the lift  
operator (attendant) to prop-  
erly open, secure and close the  
vehicle lift doors, to activate any  
auxiliary interlock (if equipped),  
to load and unload the wheel-  
chair passenger (or standee) on  
and off the lift platform, and to  
properly activate all lift functions.  
2. Pull handrail detent pins, lift  
handrails up to vertical position and  
reinsert detent pins.  
Note: Passenger must be  
positioned fully inside yellow  
boundaries.  
3. Lift outer barrier to vertical position.  
2. Press UP switch to fold outer bar-  
rier UP fully (vertical), raise the  
platform to oor level and unfold  
inner roll stop to oor level. Re-  
lease switch.  
Each handrail is secured with two de-  
tent pins (one pin at the base of each  
vertical support tube). The detent pins  
must be removed before the handrails  
can be folded or unfolded and the  
detent pins must be reinserted after  
folding or unfolding the handrails.  
4. Press the UP switch until the plat-  
form stops (raises to oor level)  
and inner roll stop unfolds to oor  
level. Release switch.  
In event of power or equipment  
failure, refer to the Manual Oper-  
ating Instructions section.  
3. Unlock wheelchair brakes and  
unload passenger from platform.  
TO UNLOAD PASSENGER:  
Hand-held Pendant Control:  
1. Read Note below! Load pas-  
senger onto platform and lock  
wheelchair brakes.  
TO STOW PLATFORM:  
DOOR  
STOW  
The hand-held attendent's pendant control is  
equipped with four push button switches (DOOR,  
STOW, DOWN and UP). The momentary switches  
activate the automatic lift functions. Simply press  
the switch labeled for the intended function.  
1. Fold outer barrier down to platform  
(horizontal) position.  
Note: Passenger must be  
positioned fully inside yellow  
boundaries and outer barrier must  
be UP.  
2. Pull handrail detent pins, fold hand-  
rails down to platform (horizontal)  
position and reinsert detent pins.  
DOWN  
UP  
When there is power to the lift, the lift function labels  
illuminate to identify the functions.  
2. Press DOWN switch until the entire  
platform reaches ground level and  
the outer barrier unfolds fully  
3. Press STOW switch until platform  
stops (retracts fully). Release  
switch.  
Control Switch Functions:  
(ramp position). Release switch.  
UP: From the stowed position, pressing the UP  
switch deploys (extends) the platform fully. Release  
the UP switch once the platform has extended fully  
in order to deploy the outer barrier and handrails.  
The platform will continue to raise to oor level if the  
UP switch is not released and handrail procedures  
may be more difcult (oor level height varies per  
vehicle). Pull the handrail detent pins and lift the  
handrails to the vertical position. Reinsert the de-  
tent pins after the handrails are raised. Lift the outer  
barrier to the vertical position. Press the UP switch  
until the platform stops (raises to oor level), and the  
inner roll stop unfolds to oor level.  
CLOSE DOOR(S)  
3. Unlock wheelchair brakes and  
unload passenger from platform.  
Manually close door(s) fully.  
STOW: The STOW function raises or lowers the  
platform to stow level and then moves the platform  
inward (retracts) to the stow position. Handrails  
and Outer Barrier: The tall outer barrier and the  
handrails must be folded down to the platform  
(horizontal) position before stowing (retracting)  
the platform. The handrail detent pins must be re-  
inserted before stowing the platform also. Note:  
The lift will not stow with weight on the platform  
(built-in safety feature).  
Note: Outer barrier must be fully  
unfolded (ramp position) until the  
entire wheelchair (or standee) has  
crossed the outer barrier.  
DOOR CLOSE: This function is not applicable  
for “Public-Use” NUVL lift models (manual door  
system and attendant operated lift).  
From ground level, the UP function will rst au-  
tomatically raise (rotate) the outer barriers to the  
upright (vertical) position. The platform then raises  
to oor level position. Note: The lift will not raise  
if the outer barrier is not in the UP position (built-in  
safety feature).  
Note: If any of these functions do not occur as  
described, discontinue lift use immediately and  
contact your sales representative or call The  
Braun Corporation at 1-800-THE LIFT®. One of  
our national Product Support representatives will  
direct you to an authorized service repairman who  
will inspect your lift.  
DOWN: The DOWN function lowers the platform  
to ground level and then unfolds the outer barriers  
to the ramp (horizontal) position. From the stowed  
position, the lift will extend fully and then lower.

Maintenance and Lubrication  
Proper maintenance is necessary to ensure safe, trouble-  
the scheduled “4500 Cy-  
cles” maintenance. These  
intervals are a general  
free operation. Inspecting the lift for any wear, damage  
or other abnormal conditions should be a part of all transit  
agencies’s daily service program. Simple inspections can  
detect potential problems.

guideline for scheduling  
maintenance procedures  
and will vary according to  
lift use and conditions. Lifts  
exposed to severe condi-  
tions (weather, environ-  
ment, contamination, heavy  
usage, etc.) may require  
inspection and maintenance  
procedures to be performed  
more often than specied.  
Maintenance and lu-  
brication procedures  
must be performed  
as specied by an  
authorized service  
technician.  
Failure to do so may  
result in serious  
bodily injury and/or  
property damage.

NUVL Series lifts are equipped with hardened pins and  
self-lubricating bushings to decrease wear, provide smooth  
operation and extend the service life of the lift.  
Maintenance Indicator:  
The Lift Ready green LED  
mounted on top of the  
pump cover will change color to yellow after every 750 cycles.  
The yellow LED will not affect the functions of the lift, but is a  
reminder to complete necessary maintenance and lubrication.  
When servicing the lift at the recommended intervals,  
inspection and lubrication procedures specied in the pre-  
vious sections should be repeated. Clean the components  
and the surrounding area before applying lubricants.  
LPS2 General Purpose Penetrating Oil is recommended  
where Light Oil is called out. Use of improper lubricants  
can attract dirt or other contaminants which could result in  
wear or damage to the components. Platform components  
exposed to contaminants when lowered to the ground may  
require extra attention.  
Inner roll stop linkage pivot points  
Lifting arm center and platform pivot points (bear-  
ings at all points)  
Once the lift has been serviced, press the CYCLE button  
(located below LCD display on the control board) until the Lift  
Ready LED changes back to green. The CYCLE button also  
clears the lift cycle count (since last service) but not the lifetime  
cycle count.  
Inspect outer barrier and lower closure for proper  
operation  
Correct or replace damaged parts.  
Inspect outer barrier seal and lower closure gasket  
Inspect outer barrier detent pin hairpin cotter  
Resecure, replace or correct as needed  
Ensure hairrpin cotter is present and can be  
removed and inserted easily. Resecure, replace  
or correct as needed.  
Lift components requiring grease are lubricated during as-  
sembly procedures. When replacing these components,  
be sure to apply grease during installation procedures.  
Specied lubricants are available from The Braun Corpora-  
tion (part numbers below).  
Discontinue lift use immediately if maintenance and lubrica-  
tion procedures are not properly performed, or if there is any  
sign of wear, damage or improper operation. Contact your  
sales representative or call The Braun Corporation at 1-800-  
THE LIFT®. One of our national Product Support representa-  
tives will direct you to an authorized service technician who will  
inspect your lift.  
Inspect lift for wear, damage or any abnormal  
condition
