Certification Checklist Diagnostic Procedures
Use the following adjustment procedures should the lift not function as described in the certification checklist.
These procedures must be followed in order for the lift to be FMVSS 403/404 compliant.
• Vehicle movement is prevented unless the platform is fully stowed.
1. Verify lift stowed signal - pin 7 on the pump module has a +12 volt output signal from lift OR pin 9 has
a ground signal from lift (depends on interlock used).
2. Refer to the interlock installation instructions.
• Lift operation shall be inhibited unless the vehicle is stopped and vehicle movement is prevented.
1. Verify vehicle secure signal (pin 6) has a +12 volt input signal from interlock.
2. Refer to the interlock installation instructions.
• The platform will not fold/stow when occupied.
1. Position the platform at the floor level loading position.
2. Loosen the locknut on the dual relief valve adjustment (do not remove locknut). See illustration below.
3. Turn the adjustment screw counter clockwise until the platform does not fold when the Fold button is
pressed.
4. Turn the adjustment screw clockwise in 1/4 turn increments and press the Fold button until the plat-
form folds completely (Note: return the platform to floor level position after each attempt to fold the
platform).
5. Turn the adjustment screw an additional 1/8 turn after the platform folds successfully.
6. Tighten the locknut without moving the adjustment screw.
7. Verify the platform will not stow while occupied.

Certification Checklist Diagnostic Procedures
• The inner rollstop will not raise if occupied.
- Call Product Support
• The outer barrier will not raise if occupied.
- Call Product Support.
• Verify platform lighting when lift is deployed.
1. Replace bulb(s) in the light housing.
2. Check fuse (5 amp fuse on circuit board; F13)
• An audio warning (and visual warning for public lifts) will activate if the threshold area is occupied when the
platform is at least 1" below floor level.
1. Remove the threshold warning plate
2. Verify the threshold strip switch connectors are connected (see illustration on Page 6)
3. Replace the threshold strip switch
4. Reinstall the threshold warning plate
• Lowering the platform beyond the inner rollstop locking position is allowed only when the inner rollstop is
locked in position.
- Call Product Support.
• Lift platform movement shall be interrupted unless the outer barrier is raised and the outer barrier latch is
positively engaged.
- Call Product Support.

Maintenance and Lubrication Schedule
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.
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 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.
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.
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
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.
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.
