Lift Terminology
Introduction:
Braun NUVL Series lifts are
ADA compliant and comply
fully with National Highway
Traffic Safety Administration
(NHTSA) specifications. The
NUVL855RM24 is commercial
oriented (intended for operation
by an attendant).
Public Use NUVL lift models
provide fully automatic operation of deploy (extend), up,
down and stow (retract) lift
functions. The NUVL855RM24
can be interfaced for fully automatic operation of the power
door system. Manual operating
procedures are required for the
shield handrails and interlocking belt.
Refer to the Lift Terminology
Illustration for identification of
lift components.
Basic lift operation procedures
are identical for all NUVL Series lift models. The operating
instructions contained in this
manual address the lift control
switches and the corresponding lift functions. Operating
procedures for the shield
handrails and interlocking belt
are provided. Instructions are
provided for manual operation
of the lift in event of power or
equipment failure.
Terminology: Become familiar
with the terminology that will be
used throughout this manual.
Become familiar with the identification of lift components and
their functions. Contact your lift
sales representative or call The
Braun Corporation at 1-800THE LIFT® if any of this information is not fully understood.
Direction: The terms "left,"
"right," "inboard," and "outboard"
will be used throughout this
manual to indicate direction (as
viewed from outside the vehicle
looking directly at the lift). Refer
to the Lift Terminology Illustration for clarification of direction
terms.
Page 5
Lift TerminologyLift Terminology
Lift Components
Refer to the Lift Terminology Illustration on page 4.
Pump Module: The remote
mounted pump module consists
of the main hydraulic pump, the
manual hand pump, the logic
control board and other electrical
components that power the lift
electric/hydraulic systems.
Hand-held Pendant Control: The hand-held pendant is
equipped with four push button
switches, (DOOR, STOW, DOWN
and UP). The momentary switches activate the automatic lift
functions. Simply press the switch
labled for the intended function.
The lift function labels illuminate
to identify the function(s). Details
regarding the control switches
and their functions are provided in
the Lift Operation section.
Lift Housing: The lift housing
is the metal structure (casing)
mounted under the vehicle which
contains and protects the platform
carriage assembly. The housing contains all lift components
except the power (pump) module
when the lift is in the stowed position.
Platform Carriage Assembly:
The platform carriage assembly
includes the platform assembly,
the lifting arms, the rolling horizontal arms that carry the platform assembly in and out of the
housing and the electrical/hydraulic drive components that power
the lift.
Platform Assembly: The lift
platform assembly consists of the
flat aluminum plate upon which
the wheelchair is positioned, the
outer barriers, the inner roll stop
and shield handrails.
Outer Barrier: The two-stage
outer barrier system consists of a
spring-loaded tall barrier and an
electric actuator-driven short barrier. The two-stage outer barrier
provides a ramp for wheelchair
loading and unloading at ground
level. Photos and further details
are provided in the Operation
Notes and Details section (pages
18-21).
Inner Roll Stop: The NUVL855RM24 is equipped with an
automatic inner roll stop that also
serves as the bridge plate. The
Page 6
Lift Terminology
inner roll stop bridges the gap
between the lift platform and the
vehicle floor. The inner roll stop
automatically rotates from the
horizontal position to the vertical position as the lift lowers and
raises. Further details regarding
the automatic mechanical inner
roll stop are provided on pages
17 and 18.
Platform Cable-activated Manual Release System: A cable-
activated manual release system
releases the platform carriage
assembly drive chain to allow the
platform carriage assembly to be
manually moved out (extended)
or moved in (retracted), should it
be necessary. Complete details
and operating procedures are
provided on page 32.
Vehicle and Lift Interlocks
Braun Corporation NUVL Series
lifts comply fully with all NHTSA
vehicle and lift interlock specifications. Vehicle movement is
prohibited unless the lift is fully
stowed and the lift will not function unless the vehicle is parked
and secured.
The NUVL855RM24 features
a visible and audible threshold
warning system that will activate
if the threshold area is occupied
when the platform is one inch or
more below floor level.
The inner roll stop and outer barriers sense weight to prohibit lift
operation. The lift will not function
if the inner roll stop or outer barriers are occupied. The lift platform
cannot be stowed if occupied.
The lift platform cannot be raised
or lowered unless the roll stop
and outer barriers are deployed
(up).
Page 7
Lift Terminology
Lift Actions and Functions:
Deploy (Extend): Lift deploy-
ment is the action of the lift platform carriage assembly extending (moving outward) from the
housing and lowering to ground
level when the DOWN switch is
activated or raising to floor level
when the UP switch is activated.
Stow (Retract): Stow is the
action of the lift platform and carriage assembly retracting (moving
inward) into the lift housing. During the stow function, the platform
will automatically raise or lower to
stow level before retracting into
the housing.
DOWN - Platform Lower: Down
is the action of the platform lowering from stow or floor level posi-
tion to fully-lowered (ground level)
position when the DOWN switch
is pressed.
DOWN - Outer Barrier Unfold (Down) - When the plat-
form reaches the fully-lowered
(ground) position and the DOWN
switch is continued to be pressed,
the outer barriers rotate downward from vertical position to
ramp position.
UP - Outer Barrier Fold (Raise):
From ground level, the UP function automatically raises (rotates)
the actuator activated outer barriers to the upright (vertical) position before the platform raises.
UP - Platform Raise: Up is the
action of the platform raising from
stow level or ground level to floor
level (fully-raised) position when
the UP switch is pressed. When
the lift is fully lowered, pressing the UP switch first raises the
outer barrier.
Note: The lift platform will not
raise if the outer barriers are not
in the upright (vertical) position.
This is a built in safety feature.
Stow Level: Stow level is the
height that the platform and carriage assembly moves in and
moves out of the lift housing.
Floor Level: Floor level is the
height that the platfom and carriage assembly raises to in order
for the wheelchair passenger to
enter and exit the vehicle (fully
raised position).

Discontinue lift use
immediately if any
lift component does
not operate properly. Failure to do so
may result in serious
bodily injury and/or
property damage.
The inner roll stop automatically
folds down to the platform surface (horizontal) during the stow
function (as platform retracts).
Interlock Feature: The inner roll
stop senses weight (pressure) to
prohibit lift operation. The lift will
not function if the inner roll stop
is occupied.
Discontinue lift operation immediately if the inner roll stop
does not operate properly.
Outer Barrier: The two-stage
outer barrier provides a ramp for
wheelchair loading and unloading at ground level (see photos
on following page). When the
platform lowers fully to ground
level, the electric actuator unfolds
(rotates) the barriers to the ramp
position (fully unfolded).
The tall outer barrier is spring
loaded but driven by the electric
actuator-powered short outer barrier to rotate from the ramp (horizontal) position to the deployed
(vertical) position.
Note: The tall outer barrier must
be manually raised and lowered
from the platform surface when
extending and retracting the
platform. Details are provided on
pages 20 and 21.
Although the outer barriers are
lift-powered, the activation of the
barriers are controlled by the lift
operator (attendant). Pressing
the DOWN switch unfolds the
barriers. The actuator-powered
two-stage outer barriers fold (rotate) to the vertical position when
the UP swiitch is pressed.
Note: The lift platform will not
raise if the outer barriers are not
fully deployed (up).
Interlock Features: The outer
barriers sense weight to prohibit lift operation. The lift will not
function if the outer barriers are

occupied. Lift platform movement shall be interrupted unless
the outer barrier is fully deployed
(up).
The attendant must view the
platform as it lowers to be certain
the entire platform reaches and
rests safely on the ground. Stop
pressing the DOWN switch if any
portion of the platform is obstructed while descending or the entire
platform does not reach ground
level for any reason (contact
with an obstruction, mechanical
failure, exceeding the lift "floor-toground" capacity, etc.). After the
platform is fully lowered, the attendant should continue to press
the DOWN switch to unfold the

Barrier, Handrail and Belt Manual Operation
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.
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. Each
handrail is secured with a latch
handle.
Page 20
The latch handles must be lifted
before the handrails can be
folded or unfolded and must be
lowered after folding or unfolding the handrails.
Interlocking Handrail Belt: The
NUVL855RM24 is equipped with
an interlocking handrail belt.
Once the lift platform has extended fully from the stowed position,
the belt must be latched in order
to raise or lower the platform.
During the Stow function, the
belt must be unfastened after the
platform raises or lowers to stow
level and stops. With the belt
unlatched, pressing the STOW
switch then retracts the platform
fully.

Operation Notes and Details
Lift Passengers
If you are an attendant operating
the lift, it is your responsibility to
perform safe loading and unloading procedures. Wheelchair lift
attendants should be instructed
on any special needs and/or procedures required for safe transport of wheelchair passengers.
The lift operator and bystanders
must keep clear of the area in
which the lift operates. Observe
your passenger at all times during
lift operation.
Do not attempt to load or unload
a passenger in a wheelchair or
other apparatus that does not fit
on the platform area. Do not exceed the 700 pound load capacity
of the lift. The lift attendant should
not ride on the platform with the
passenger.
Passenger Orientation (Boarding Direction): Braun "Public
Use" NUVL Series wheelchair lifts
accommodate both inboard and
outboard facing wheelchair passengers or standees. Inboard facing of wheelchair lift passengers is
not prohibited, but outboard facing of passengers is recommend-
ed by The Braun Corporation.
Braun "Public Use" NUVL Series lifts permit both inboard and
outboard facing of wheelchair and
mobility aid users and accom-
modate persons using walkers,
crutches, canes or braces or who
otherwise have difficulty using
steps.
Standees: Lift Operating Instructions apply to wheelchair passengers and standees. Standees
should stand in the center of the
platform (fully inside the yellow
boundaries) and grip both handrails (if able) when on platform.
Yellow Boundaries: The passenger must be positioned in the

Platform side plates and handrail
bases are powder coated yellow
also.
Threshold Warning: The vehicle
-mounted black threshold warning
mats identify the platform threshold area. Interlock: A visible and
audible threshold warning system
will activate if the threshold area
is occupied when the platform
is one inch or more below floor
level.
The attendant must always be
certain the wheelchair passenger
or standee is properly positioned
on the platform (fully inside yel-
low boundaries) and the wheelchair brakes are locked when a
passenger is on the lift platform.
The lift passenger must keep
hands, arms and all other body
parts within the lift occupant area
and clear of all moving parts.
Vehicle (Floor Level) Loading
and Unloading: The platform
must be fully raised (at floor level)
and the inner roll stop must be
properly positioned when loading
or unloading passengers in or out
of the vehicle. It is the responsi-
bility of the lift attendant to ensure the platform and the inner
roll stop are properly positioned
at floor level when loading and
unloading passengers.
The wheelchair brakes must be
locked, the outer barriers must be
in the fully-deployed (up) position
and the handrail belt must be
latched whenever a passenger
is on the platform.
Whenever a
passenger is on the
platform, the:
• Handrail belt must
be latched
• Passenger must be
positioned in the
center of the
platform.
• Wheelchair brakes
must be locked
• Inner roll stop and

Turn powered (electric) wheelchairs off when on the platform.
If the outer barriers, inner roll
stop, handrails, handrail belt
or any other lift component
does not operate as outlined in
this manual, discontinue lift
use immediately and contact
The Braun Corporation sales
representative in your area or
call The Braun Corporation at

national Product Support representatives will direct you to an
authorized service technician
who will inspect your lift.
The Braun Corporation recommends wheelchair passengers
position and buckle their wheelchair-equipped seat belt (torso
restraint) before loading onto a
wheelchair lift.
Different types of disabilities
require different types of wheelchairs and different types of
wheelchair-equipped occupant
restraint belt systems (torso
restraints). It is the responsibility of the wheelchair passenger
to have his or her wheelchair
equipped with an occupant
restraint (seat belt) under the
direction of their health care
professional.

Wheelchair lift attendants
should be instructed on any
special needs and/or procedures required for safe transport of wheelchair passengers.
Position and secure

fasten, etc.) the
wheelchair-equipped
occupant seat belt
before loading onto
the wheelchair lift
platform. Failure to
do so may result in
serious bodily injury
and/or property

Operation Notes and Details
Operation Procedure Review
The Braun Corporation recommends that transit agency supervisors and wheelchair lift attendants review the safety precautions and operation procedures
appearing in this manual and on
lift operating instruction decals
with your wheelchair lift sales
representative (dealer), before
attempting lift operation.
Any questions or concerns can
be answered by the sales representative at that time. Operate
the lift through all functions with
your sales representative on
hand to ensure the proper use
and operation of the wheelchair
lift is understood.
Transit agency supervisors
should train and educate their
lift attendants on the proper use
and operation of the wheelchair
lift if it is not possible for the
attendants to review the safety
precautions and operation procedures with the wheelchair lift
sales representative.
The lift operator's manual must
be stored in the lift vehicle at
all times.

Preventive Maintenance:
W
A
RNING
Operation Notes and Details
Maintenance is necessary to
ensure safe and troublefree
lift operation. General preventive lift maintenance consisting
of careful inspections of the
lift system and cleaning the lift
should be a part of your transit
agency's daily lift service program. Simple inspections can
detect potential lift operational
problems.
Keeping the lift platform and
housing area clean is one of
the most effective preventive
maintenance practices to exercise. Dirt, mud, snow, ice and
other debris entering the housing could result in potential lift
problems.
Page 26
Regular preventive maintenance
will reduce potential lift operation
downtime and increase the service life of the lift, as well as possibly detecting potential hazards.
Exposure to harsh weather elements, environmental conditions,
or heavy usage may require
more frequent maintenance and
lubrication procedures.
Preventive maintenance visual inspections do not take the
place of the procedures specified
in the Maintenance and Lubrication Schedule provided on pages
40-48 of this manual. Refer to
the Maintenance and Lubrication
section for further details.
Maintenance and
lubrication procedures
must be performed
by authorized service
personnel as specified
in this manual. Failure
to do so may result in
serious bodily injury
and/or property
damage.

The following operations have been verified upon
installation. This operational checklist can be used
at any time to verify the lift is fully functional.
Verified:
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.
The platform will not fold/stow if occupied.
The inner roll stop will not raise if occupied.
Verify platform lighting when lift is deployed and
pendant illumination when lift is powered.
The outer barrier will not raise if occupied.
A visual and audible warning will activate if the
threshold area is occupied when the platform is at
least one inch below floor level.
Platform movement is prohibited
beyond the position
where the inner roll
stop is fully deployed (up).
Discontinue lift use

Manual Operating Instructions
Cable-Activated Platform Manual Release System
Platform Manual Release System: A cable-activated manual
release system releases and engages the platform carriage assembly drive chain to allow the platform
carriage assembly to be manually
moved out (extended) or moved in
(retracted) as needed. A T-handle
is provided on the release cable
for activation of the manual release
system (details follow).
After manually moving the platform
in or out, it is extremely important
that the cable-activated manual
release is positively re-engaged to
secure (lock) the platform carriage
assembly before loading a passenger on the platform or before driving
the vehicle.
Grasp the outer barrier and move
the platform in and out until the
Page 32
platform locks (chain release
assembly engages), securing the
platform carriage assembly within
the housing. You will feel the release mechanism engage.
Failure to manually lock the platform carriage assembly (re-engage
the carriage assembly drive chain)
after manual deployment, will allow the platform to roll in or out of
housing unhindered during vehicle
movement. Failure to lock the platform will also allow the platform to
roll in or out of housing unhindered
during hand pump raising and lowering procedures.
After manually releasing platform, push manual release
T-handle in fully and ensure
platform is locked before driving
lift vehicle. Uncontrolled and
unintentional platform deployment (inadvertent platform ejection) may result in serious bodily
injury and/or property damage.

Maintenance and Lubrication
W
A
RNING
Proper maintenance is necessary to ensure safe,
troublefree 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. The maintenance and lubrication procedures specified in the following schedule must be
performed by a Braun authorized service representative at the scheduled intervals according to the
number of cycles. NHTSA NUVL Series lifts are
equipped with a cycle counter (digital display built
into the electronic control board).
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.
When servicing the lift at the recommended intervals, inspection and lubrication procedures specified in the previous sections should be repeated.
Clean the components and the surrounding area
before applying lubricants. LPS2 General Pur-
pose 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.
Lift components requiring grease are lubricated
during assembly procedures. When these components are replaced, grease must be applied during
installation procedures. Specified lubricants are
available from The Braun Corporation (part numbers provided on page 41).
Maintenance and
lubrication procedures must be performed as specified
by an authorized
service technician.
Failure to do so may
result in serious
bodily injury and/or
property damage.
Page 40
Maintenance and Lubrication
All listed inspection, lubrication and maintenance
procedures should be repeated at “750 cycle”
intervals following the scheduled “4500 Cycles”
maintenance. These intervals are a general
guideline for scheduling maintenance procedures
and will vary according to lift use and conditions.
Lifts exposed to severe conditions (weather,
environment, contamination, heavy usage, etc.)
may require inspection and maintenance procedures to be performed more often than specified.
Maintenance Indicator: The Lift Ready green
LED, mounted on the hand-held pendant storage
bracket, 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
See the Maintenance/Lubrication Schedule for recommended applications per number of cycles.
