Introduction:

Braun NL Millennium Series
lifts are ADA compliant and
comply fully with National

+LJKZD\7UDIÀF6DIHW\$GPLQLV­WUDWLRQ1+76$VSHFLÀFDWLRQV

The NL is commercial oriented
(intended for operation by an
attendant).

Lift models vary per size (lift
model numbers indicate lift
dimensions). NL Series lift
models can be equipped with
left or right side pump modules
as needed. A left side pump­equipped lift model is depicted
in the Lift Terminology Illustra­tion (NL917IB). Right side
pump lift models are a mirrored
image of rear pump models

(pump module located on op­posite end of base plate).

lift components.

Lift operation procedures
are identical for all NL 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

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 Termi­QRORJ\,OOXVWUDWLRQVIRUFODULÀFD­tion of direction terms.

Lift Components

Refer to the Lift Terminology Il­lustration on page 4.

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.

Hand-held Pendant Control:

The hand-held attendant's
pendant control is connected to
the pump module. The hand­held pendant is equipped with
two rocker switches, (UNFOLD,
FOLD, DOWN, and UP). The
momentary switches activate the
automatic lift functions.

Lift Frame: The lift frame con­sists of the base plate, threshold
warning plate, towers, parallel
arms, vertical arms, platform
pivot arms and handrails. 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.

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
inner roll stop, and the hydraulic
cylinder assembly that powers
the outer barrier.

™

Lift-Tite

Latches: The spring-

loaded latches prevent the
platform from unfolding from the
stowed position in the event of
platform drift. Further details

™

regarding Lift-Tite

latches are

provided on pages 16 and 17.

Outer Barrier: The cylinder­powered automatic outer barrier
provides a ramp for wheelchair
loading and unloading at ground
level. Photos and further details
regarding the outer barrier are
provided in the Operation Notes
section (pages 19-21).

Outer Barrier Latch: The spring­loaded latch locks the outer bar­rier in the vertical position when
the platform raises above ground
level.

Page 6

Lift Terminology

Inner Roll Stop: NL Series lift
models are equipped with an
automatic inboard roll stop that
also serves as the bridge plate.
The roll stop bridges the gap
between the lift platform and the

YHKLFOHÁRRU7KHLQQHUUROOVWRS

automatically rotates from the
horizontal position to the verti­cal position as the lift lowers and
raises. Further details regard­ing the automatic mechanical

is fully stowed and the lift will
not function unless the vehicle
is parked and secured.

The NL features a visible and
audible threshold warning
system that will activate if the
threshold area is occupied
when the platform is one inch or

PRUHEHORZÁRRUOHYHO

The inner roll stop and outer
barrier sense weight to prohibit
lift operation. The lift will not
function if the inner roll stop or

the outer barrier are occupied.
The lift platform cannot be folded
(stowed) if occupied.

The inner roll stop features a
locking mechanism that prohib­its the platform from lowering if
the lock does not engage. The
lift platform cannot be raised
more than 3" above ground
level unless the outer barrier is
in the vertical position and the
outer barrier latch is positively
engaged.

Interlock Features: The inner
roll stop features a locking
mechanism that prohibits the plat­form from lowering if the lock is
not engaged. The inner roll stop
also senses weight to prohibit lift
operation. The lift will not function
if inner roll stop is occupied.

Discontinue lift operation im­mediately if the inner roll stop
does not operate properly.

Outer Barrier: This cylinder-pow-

ered 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 cylinder compression spring

automatically unfolds (rotates)
the barrier to the ramp position
(fully unfolded).

Although the outer barrier is
lift-powered, the activation of
the barrier is controlled by the
lift operator (attendant). Press­ing the DOWN switch unfolds
the barrier. The outer barrier is
cylinder-powered to automati­cally fold (rotate) to the vertical
position as shown when the UP

Fully-Unfolded Barrier (Ramp position)

Page 20

Operation Notes and Details

The latch disengages the barrier
when the platform lowers fully
(reaches ground level) and the
latch foot contacts the ground
(latch raises above the barrier).

Outer Barrier and Latch Op­eration: The lift attendant must

press the DOWN switch to lower
the platform fully to the ground.
The attendant must view the
platform as it lowers to be cer-
tain 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 rea-
son (contact with an obstruction,
mechanical failure, exceeding

WKHOLIW´ÁRRUWRJURXQGµFDSDFLW\

etc.).

After the platform is fully low­ered, the attendant should con­tinue to press the DOWN switch
to unfold the outer barrier fully
(ramp position). Note: The
barrier must be fully unfolded
until the entire wheelchair (or
standee) has crossed the barrier
when loading or unloading at
ground level. Discontinue lift

operation immediately if the
outer barrier or latch do not
operate properly.

Bridging: The NL incorpo-

rates 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.

Handrails: Dual handrails are
provided for wheelchair pas­senger (or standee) use. The
handrails unfold automatically
to the deployed (horizontal)
position when the lift unfolds
and automatically fold to the
stowed (vertical) position when
the platform folds.

If able, passengers should
grip both handrails when on
the lift platform. Discontinue

lift operation immediately if
the handrails do not operate
properly.

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

RWKHUDSSDUDWXVWKDWGRHVQRWÀW

on the platform area. Do not ex­ceed the 800 pound load capac-

ity of the lift. The lift attendant
should not ride on the platform
with the passenger.

Passenger Orientation (Board­ing Direction): Braun NL 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 recommended
by The Braun Corporation.

Braun NL Series lifts permit both
inboard and outboard facing of
wheelchair and mobility aid us­ers and accommodate persons
using walkers, crutches, canes
or braces or who otherwise have

GLIÀFXOW\XVLQJVWHSV

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
center of the platform to pre­vent side-to-side load imbalance.
The lift attendant (operator)
should not ride on the platform
with the passenger.

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-posted 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.

Page 25

Operation Notes and Details

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-mounted
manual storage pouch at all
times.

Preventive Maintenance:

Maintenance is necessary to en­sure safe and troublefree lift op­eration. General preventive lift
maintenance consisting of care-
ful 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.

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

Inspect your lift for any miss­ing or worn antiskid. Order
as needed. Note: Clean
surfaces with isopropyl alco­hol before decal or antiskid
application. Use a clean
cloth or paper towels. Do
not use oily shop rags. Wipe
surface free of residue with
dry portion of cleaning cloth.

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 all transit agencies's daily
service program. Simple inspections can detect
potential problems.

The maintenance and lubrication procedures
VSHFLÀHGLQWKHIROORZLQJVFKHGXOHmust be per-
formed 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

repeated. Clean the components and the sur­rounding area before applying lubricants.

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.

Lift components requiring grease are lubricated
during assembly procedures. When these compo­nents are replaced, grease must be applied during

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.
