Introduction:
Braun NL955 Millennium Series
lifts comply fully with the National
Highway Traffic Safety Administration (NHTSA) specifications.
The Braun NL955 is consumer
oriented (designed to allow operation by the wheelchair passenger). NL955 lift models provide
fully automatic operation of all
lift functions as well as optional
automatic door operators (if so
equipped).
Lift models vary per platform size
(lift model numbers indicate lift
dimensions). A standard NL955
lift model is depicted in the Lift
Terminology Illustration. Refer to
the Lift Terminology Illustration
for identification of lift components.
Lift operation procedures are
identical for all NL955 Series
lift models. The operating
instructions contained in this
manual and appearing on liftposted operating instructions
decals address the lift control
switches and the corresponding lift functions. 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

Pump Module: The lift-mounted
pump module consists of the
hydraulic pump, the manual
hand pump, the electronic
control board and electrical
components that power the lift
electric/hydraulic systems. The
pump module is equipped with
three function-labeled control
switches.
Hand-held Pendant Control:
The hand-held attendant's pendant control is connected to the
pump module. The hand-held
pendant is equipped with four
push button switches, (UNFOLD,
Page 6
FOLD, DOWN, and UP). The
momentary switches activate the
automatic lift functions. The lift
function labels illuminate to identify the function(s).
Lift Frame: The lift frame consists of the base plate, threshold
warning plate, towers, parallel
arms, vertical arms, platform
pivot arms and switch arm. Two
main hydraulic cylinders are
housed in the parallel arms.
The electrical/hydraulic powered
lift frame components mechanically unfold, lower, raise and fold
the lift platform assembly.
Switch Arm: An additional
UP/DOWN switch is provided on
the switch arm.
Platform Assembly: The platform assembly consists of the
steel tubing frame with grating
surface upon which the wheelchair is positioned, the outer
barrier, outer barrier latch, the
inboard locator, side entry and the
hydraulic cylinder assembly that
powers the outer barrier.
Lift-Tite™ Latches: The springloaded latches prevent the
platform from unfolding from the
stowed position in the event of
platform drift. Further details

the event of platform drift.
Due to the “all-hydraulic”
operation of the dual-cylinder
NL955, hydraulic fluid expansion, contraction or seepage
may occur. Any of these
conditions may result in platform drift (failure to hold the
platform in the folded or raised
position). Platform drift may
occur during lift shipment and/
or between extended periods
of non-lift use.
In the event that the platform
does not unfold when the UNFOLD switch is pressed, press
the FOLD switch momentarily
to disengage the Lift-Tite™
latches (platform drift has
occurred). Then, press the
UNFOLD switch to unfold the
platform to floor level (stan-
dard operation). When manually
operating a lift equipped with
Lift-Tite™ latches, insert the pump
handle in the pump and stroke until the platform folds fully (stops).
Then, open the hand pump valve
(turn counterclockwise) to unfold
the platform. Folding the platform fully first will ensure that the
Lift-Tite™ latches will disengage
properly when the release valve
is opened. Manual Operating Instructions are provided on pages

Lift Features (continued):
Inboard Locator and Bridge
Plate: NL955 Series lift models
are equipped with an automatic
inboard locator that also serves
as the bridge plate (inboard
locator photos below).
When the UNFOLD switch is
pressed and the platform unfolds
from stow position to floor level,
this mechanical locator/bridge
plate is automatically deployed to
the bridging (horizontal) position
to provide a bridge plate between
the platform and the lift base plate
(vehicle floor). The inboard edge

of the bridge plate rests on the
threshold warning plate (base
plate).
The locator/bridge plate automatically folds (rotates) to the
vertical (roll stop) position when
the platform lowers to the ground
(DOWN switch is pressed). As
Operation Notes and Details
the UP switch is pressed and the
platform raises from ground level,
the inboard locator automatically
unfolds (rotates) to the horizontal (bridging) position when it
reaches vehicle floor level. The
bridge plate must overlap the lift
base plate a minimum 1/2".
When the FOLD switch is
pressed and the platform folds
from floor level to the stow (vertical) position, the bridge plate
automatically travels inboard to
the stowed position.
Interlock: The inboard locator
senses weight to prohibit lift operation if occupied.
Automatic Floor Level Switching: When the platform unfolds
from the stowed position, the platform stops automatically at floor
level when fully unfolded. When
raising the platform from ground
level, the platform automatically
stops at floor level when raised
fully.
Although the NL955 features
automatic floor level switching,
the lift operator (wheelchair passenger or attendant), must view
the platform to be certain the
platform is properly positioned at
vehicle floor level and the bridge
plate is properly positioned when
a passenger is entering or exiting
the vehicle. If the lift platform
does not automatically stop at
floor level as outlined,
discontinue lift operation immediately.
Outer Barrier and Side Entry:
The NL955 platform is equipped
with an outer barrier and a side
entry. See photos A, B and
C. The cylinder-powered outer
barrier and side entry provide a
Belt-operated Side Entry

ramp for wheelchair loading and
unloading at ground level. The
side entry is useful in tight parking
situations by reducing wheelchair
caster “turn-out” when boarding
and exiting the platform. The
barrier and side entry function in
unison. Discontinue lift oper-
ation immediately if the outer
barrier or side entry do not
operate properly.
Outer Barrier: When the platform lowers fully to ground level,
the roll stop cylinder compression spring automatically unfolds
(rotates) the outer barrier to the
ramp position (fully unfolded).
Although the outer barrier is liftpowered, activation of the barrier
is controlled by the lift operator.
Activating either DOWN switch
unfolds the barrier. The barrier is
cylinder-powered to automatically

when the UP switch is activated
(barrier raises before platform

Outer Barrier Latch: A springloaded latch engages the outer
barrier when the barrier rotates
upward from ramp position to
the vertical position (UP switch
is activated to raise the platform
above ground level).
Note: The platform must raise
approximately three inches before the latch engages fully (see
photo C on page 22).
The latch disengages the barrier

The lift operator or attendant must
be certain the entire platform
reaches and rests safely on the
ground.
Page 23
Operation Notes and Details
Lift Features (continued):
Interlock: Lift platform movement will be interrupted unless
the barrier is raised and the
outer barrier latch is positively
engaged.
Outer Barrier and Latch Operation: The lift operator must
activate the DOWN switch to
lower the platform fully to the
ground. The lift operator or attendant must view the platform
as it lowers to be certain the
entire platform reaches and
rests safely on the ground. Stop
activating the DOWN switch if
any portion of the platform is obstructed while descending or the
platform does not reach ground
level for any reason (contact
with an obstruction, mechanical
Page 24
failure, exceeding the lift “floorto-ground” capacity, etc.).
After the platform is fully lowered
(platform reaches the ground),
the lift operator should continue
to press the DOWN switch to
unfold the outer barrier and the
side entry fully (ramp position).
Note: The outer barrier and side
entry must be fully unfolded
until the entire wheelchair has
crossed when loading or unloading at ground level. Discontinue lift operation immediately
if the barrier or latch do not
operate properly.
Bridging: The NL955 incorporates a bridging feature. This
feature stops the down travel of
the platform if the outboard end
of the platform contacts a raised
surface (such as a curb), preventing the operator from lowering the
inboard end of the platform.
Switch Arm: The switch arm
automatically unfolds to the deployed position when the platform
unfolds and folds automatically
to the stowed position when the
platform folds. The passenger
may choose to grip the switch arm
when on the lift platform.
Note: The switch arm is equipped
with an UP/DOWN control switch
(page 16). Discontinue lift
operation immediately if the
switch arm does not operate
properly.

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
750 pound load capacity of the lift.
Passenger Orientation (Boarding Direction): The wheelchair
passenger must face outward
whenever on the platform.
The passenger must be positioned
in the center of the platform to
prevent side-to-side load imbalance. Other persons should not
ride on the platform with the
wheelchair passenger.
The wheelchair brakes must be
locked, the inboard locator and
the outer barrier must be in the
fully-up (vertical) position, and
the outer barrier latch must be
fully engaged whenever a
wheelchair passenger is on
the platform.
Do not use the outer barrier as
a brake. Stop and brake the
wheelchair when fully loaded
on the platform. Manually stop
and brake manual wheelchairs.
Stop powered wheelchairs with
the wheelchair controls. Turn
powered (electric) wheelchairs
off when on the platform.
Vehicle (Floor Level) Loading
and Unloading: The platform
must be fully raised (at floor
level) and the bridge plate must
be properly positioned when
loading or unloading a passenger
in or out of the vehicle. Although
the NL955 features automatic
floor level switching, it is the
responsibility of the lift operator to ensure the platform and
the bridge plate are properly
positioned at floor level when
loading and unloading passengers.
Interlock: An audible threshold warning will activate if the
threshold area is occupied when
the platform is one inch or more
below the level. The threshold
warning plate identifies the
platform threshold area.
If the outer barrier, inboard locator
or any other lift component does
not operate as outlined in this
manual, discontinue lift use immediately and contact your sales
representative or call The Braun
Corporation at 1-800-THE LIFT®.

Operation Notes and Details
One of our national Product
Support representatives will
direct you to an authorized
service technician who will
inspect your lift.
WARNING
Position and secure
(buckle, engage,
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 damage.
Page 26
Wheelchair-Equipped Occupant Seat Belts
The Braun Corporation recommends wheelchair passengers
position and buckle their wheelchair-equipped seat belt (torso
restraint) as specified by the
manufacture before loading onto
a wheelchair lift.
Wheelchair lift attendants should
be instructed on any special
needs and/or procedures required
for safe transport of wheelchair
passengers.
Different types of disabilities
require different types of wheelchairs and different types of
wheelchair-equipped occupant
restraint belt systems (torso restraint). 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.
The Braun Corporation recommends that the wheelchair lift
user and/or attendant review the
safety precautions and operation procedures appearing in this
manual and on lift-posted decals
with your wheelchair lift sales
representative, before attempting lift operation. Any questions
or concerns can be answered by
your sales representative at that
time.
Operation Procedure Review
Operation Notes and Details
Using your own wheelchair,
operate the lift through all functions and enter and exit the
vehicle with the sales representative on hand to ensure the lift
is right for you as the end user
(applicable for your use based
on your physical abilities and the
physical characteristics of your
personal wheelchair). Become
familiar with the proper operation
of your lift before operating the
lift by yourself.
This lift operator’s manual must
be stored in the lift-mounted
manual storage pouch when
not in use.
Preventive Maintenance
Maintenance is necessary to
ensure safe and trouble-free lift
operation. Preventive lift maintenance consisting of careful
inspections of your lift system and
cleaning the lift should be a part
of your routine. Simple inspections can detect potential lift
operational problems.
Regular preventive maintenance
will reduce potential lift operation downtime and increase the
service life of the lift, as well as
enhancing safety.
• Do the automatic door(s) open
fully (if equipped)?
• Does the lift safely clear the
door(s) when unfolding and
folding?
• Do the lift control switches function properly?
• Do the automatic inboard locator and outer barrier operate
properly?
• Does the outer barrier latch
operate properly?
• Does the switch arm fuction
properly?
• Is the power source adequate or
weak?
During routine inspections, operate the lift through a minimum of
one complete cycle and note the
following:

Maintenance and Lubrication
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 a regular 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.
NL 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 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.
WARNING
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.
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 44).
Page 43
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 top of the pump cover will begin
to blink after every 750 cycles. The blinking LED
will not affect the functions of the lift, but is a
reminder to complete necessary maintenance and
lubrication. Once the lift has been serviced, fully
stow the lift. Once stowed, press the UP button
on the hand pendant and the Floor Level Set button on the back side of the pump cover until the
Lift Ready green LED stops blinking.
Discontinue lift use immediately if maintenance
and lubrication 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 representatives will direct you to an authorized service
technician who will inspect your lift.
See the Maintenance/Lubrication Schedule for recommended applications per number of cycles.

The Braun Corporation of Winamac, Indiana, warrants that it will repair (or replace at
Braun’s sole option) any defect in material or workmanship in its wheelchair lift for three years,
providing the lift is installed, operated and maintained properly. This warranty is limited to the
original purchaser and does not cover defects in the motor vehicle on which it is installed, or
defects in the lift caused by a defect in any part of the motor vehicle.
This warranty commences on the date the lift is put in service, providing the warranty
registration card is completed and received by The Braun Corporation within 20 days of purchase.
If no warranty card is received, the warranty will expire three years from the date of manufacture
as identified on the lift serial number tag.
This warranty also covers the cost of labor for the repair (or replacement at Braun’s sole
option) of parts for one year when performed by an authorized Braun representative. (A labor
schedule determines cost allowance for repairs and is available upon request).
This warranty does not cover normal maintenance, service, or periodic adjustments
necessitated by use or wear. The Braun Corporation will not, under any circumstances, pay for loss
of use, incidental, or consequential damages related to the lift or vehicle in which it is installed.
This warranty will become null and void if the lift has been damaged through accident,
misuse, or neglect, or if the lift has been altered in any respect.
