Platform Angle Adjustment
Adjusting the platform angle based on the
Millennium “NL” Series
relationship of the platform at ground level
directly affects the angle of the platform
when positioned at floor level.
Figure C
Unfold the lift and visually examine the
angle of the platform when positioned at
floor level. Lower the platform fully and
note the angle of the platform when it
reaches ground level also. The outboard
end of the platform (toe) must contact
the ground first when the platform is
lowered (all lift models).
Angle A

Millennium “NL” Series:
The platform angle should be adjusted so
there is a balance between the angle at
both positions (equal amount of angle).
Angle A should equal angle B as shown
in Figure C.

LCD Lift Codes
To better understand the Braun LCD Trouble shooting display you must first understand the numbers that
appear on the screen. There are Flashing Codes, Solid Error Codes, and Solid Normal Operational Codes.
Flashing Codes #65-89: About 10 seconds after an operation has stopped there are a set of scrolling
flashing numbers that indicate whenever a particular sensor or switch has been activated. These numbers
will start at number 65 and scroll up to number 89, then start the sequence over. Remember they are not
error codes. Keep in mind that the lift will display codes for different positions and certain flashing codes
must be present for that position, you will not always get an error code.
Solid Error Codes #50-64: These are the numbers that will come on the screen when the audible and
visual alarm goes off, and will direct you to where the problem exists. These numbers will only stay on the
screen for about 10 seconds and then the flashing codes will scroll indicating what sensors are active. This
sequence of codes will keep repeating. It is important to be looking at the screen when trying to get the lift
to fail.
Solid Normal Operational Codes: There are also solid numbers that will appear while and after the lift is
moving that indicate the lift operation and platform position.
Troubleshooting Procedures
1. While looking at the LCD screen, operate the lift until the failure occurs. Read the number that comes
on the display the moment the alarm goes off and the light starts to flash. This code will only stay on the
screen for 10 seconds.
2. Look up the number on the correct error code sheet and determine what part on the lift is causing the
failure. Go to the part on the lift that is suspected of causing the failure and look for anything obvious like
magnets missing, broken wires etc. If nothing is found, the next step is to determine if that sensor is send-
ing a signal to the board.
3. Bring the platform to the level that the sensor should be activated using the backup pump if needed. At
this point, look up the flashing code that corresponds to that sensor in the error code sheet, look at the LCD
screen and wait for the flashing scrolling numbers to appear. If the number is not included in the scrolling
numbers, you know that sensor is the problem. You should then check the harness or try another magnet
with the south side of the magnet facing the sensor and see if the number will come up on the display.
4. If the problem is still not found or the harness is suspected, the voltages should to be checked to and
from the sensor to find the exact location of the problem. First determine the 3 wire colors for this sensor at
the board and understand the 3 voltage readings needed to operate the sensor, the 12V power, 8V power,
and the 8V input signal to the PC board when activated by a magnet. First check for a 8V input signal
coming from the sensor to the wire going into the PC board, if there is 11V on this wire, the sensor is not
being activated by the magnet. Next check the 12V and 8V wires at the PC board plug leading to the sen-
sor. Once verified at the plug on the PC board, the voltages should then be checked at the next plug down
on the harness going to the sensor until the location of the problem is found.
Anytime you see the code for that specific switch you will have 8 volts on that colored wire on the 8 or 18
pin connector from that switch. IE: Outboard Barrier is closed “72” will appear on the screen and also 8V
will be present on the signal wire from that switch, if no code is present the voltage will be 11V.

Maintenance and Lubrication Schedule
following the scheduled
“4500 Cycles” mainte-
nance. These intervals
are a general guideline
for scheduling mainte-
nance procedures and
will vary according to
lift use and conditions.
Lifts exposed to severe
conditions (weather, envi-
ronment, contamination,
heavy usage, etc.) may
require inspection and
maintenance procedures
to be performed more
often than specified.
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.
W
ARNING
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
The maintenance and lubrication procedures specified
in this schedule must be performed by a Braun autho-
rized service representative at the scheduled intervals
according to the number of cycles.
Braun dual parallel arm lifts are equipped with hard-
ened pins and self-lubricating bushings to decrease
wear, provide smooth operation and extend the service
life of the lift.
damage.
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 apply-
ing 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.
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 opera-
tion. 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.
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 above).
All listed inspection, lubrication and maintenance
procedures should be repeated at “750 cycle” intervals

Braun™ Five-Year
Limited Warranty
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 five 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 three years 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.
* The five-year portion of this warranty covers the following lift’s power train parts:
• Cable • Cylinder • Flow Control • Gear Box • Motor • Pump • Hydraulic Hose & Fittings
• Solid State Controller
All remaining lift components are covered by a three-year warranty.
Return Authorization Procedure
When processing any warranty claims (parts, repairs, etc.), all requests must be processed through The
Braun Corporation Product Support Department. Call 1-800-THE LIFT® during normal working hours.
Product Support will issue a Return Material Authorization (RMA) number and detail the procedures
required for processing returns and/or authorizing credit.
The lift identification information is provided on the Braun Serial No./Series No. identification tag and
the two warranty cards (shown on inside front cover). The lift identification information must be
provided when filing a warranty claim or ordering parts.
