“DOT — Public Use Lift” veries that this platform lift meets the
“public use lift” requirements of FMVSS No. 403. This lift may be
installed on all vehicles appropriate for the size and weight of the
lift, but must be installed on buses, school buses, and multi-
purpose passenger vehicles other than motor homes with a gross
vehicle weight rating (GVWR) that exceeds 4,536 kg (10,000 lb).

The following operations and conditions must be functionally veried in order for the lift to be FMVSS
403/404 compliant. If an operation does not function as described or a condition is not met, follow the refer-
enced procedures to correct the problem or contact BraunAbility Aftersales.
• Vehicle movement is prevented unless the lift door is closed, ensuring the lift is stowed.
1. Verify on the pump module mounted interlock connecter that the lift stowed signal - pin 9 has a
ground signal OR lift not stowed signal - pin 5 has an open signal (depends on interlock used).
2. Refer to the interlock installation instructions.
• Lift operation shall be prevented unless the vehicle is stopped and vehicle movement is prevented.
1. Verify vehicle secure signal (pin 6) has a +12 volt signal.
2. Refer to the interlock installation instructions.
• The platform will not fold/stow if occupied.
- Refer to Platform Fold Pressure Adjustment procedures.
• The inner roll stop will not raise if occupied.
• The outer barrier will not raise if occupied.
• Verify platform lighting when lift is deployed and pendant illumination when lift is powered.
• A visual and audible warning will activate if the threshold area is occupied when the platform is greater
than 1" below oor level.
1. Verify Tower 3 (Alarm) Switch Adjustment on page 8.
2. Remove the threshold warning plate.
3. Verify the threshold strip switch connector is securely connected.
4. Reinstall threshold warning plate.
5. Test threshold warning (push down on plate). If warning is not activated, see Step 5.
6. Remove the threshold warning plate and replace non-functioning threshold switch.
7. Repeat Step 4. If warning is still not activated, call BraunAbility Aftersales.
• Platform movement is prohibited beyond the position where the inner roll stop is fully deployed (up).
• Platform movement shall be interrupted unless the outer barrier is deployed (up).

Both adjustment screws must be
adjusted equally. Apply Loctite®
to adjustment screws following
adjustment.
Platform Stop Blocks: When
adjusting platform angle, en-
sure both stop blocks are mak-
ing full contact with the vertical
arms (see photo at right and
details on following page).

See Figure B.
The angle of the platform at
ground level directly affects
the angle of the platform when
positioned at oor level.
Raise the platform to oor

The platform at oor level
should have a slight upward

Tower 3 (Alarm) Switch Adjustment
Threshold Alarm Switch
1. Position platform at the fully raised
(oor level) position using the pen-
dant control.
2. Place pressure on the threshold
warning plate (base plate). Con-
tinue applying pressure to threshold
plate and turn switch adjustment
screw clockwise until alarm sounds.
If alarm sounds when pressure is
rst applied go to Step 3.
3. Continue applying pressure to
threshold plate and slowly turn
switch adjustment screw coun-
terclockwise until the alarm stops
sounding.
Tower 4 (Fold) Switch Adjustment
Partial Fold Switch
1. Position platform at 45˚ angle using
the manual hand pump or pendant
control.
2. View the Tower 4 microswitch inside
the lift tower (see Photo G). Turn
the switch adjustment screw in or
out as needed until the radius of the
microswitch blade rides on the apex
of the activation plate.
3. Verify proper adjustment. Criteria
below must be met.
Proper Adjustment Criteria:
• Apply pressure (push down) on
outboard end of platform by press-
ing the hand pendant FOLD switch.
The platform should not fold (stow)
with light pressure applied.
• When folding fully, the platform
should stow tightly (snug with stow
blocks).
Figure D Note: Left (rear) pump lift
depicted. Right (front) pump
lift is a mirrored image.
Note: Review adjustment
procedures below and adjust
as needed only.
Tower 1 (Unfold) Switch Adjustment
Floor Position from Stow
1. Position platform at the fully stowed
position using the manual hand
pump or pendant control.
2. Turn switch adjustment screw clock-
wise 3 full turns.
3. Press pendant UNFOLD switch (con-
tinue pressing switch until platform
stops unfolding).
4. When platform stops unfolding, turn
switch adjustment screw coun-
terclockwise while pressing the
pendant UNFOLD switch. Platform
position will change. Repeat adjust-
ment until criteria below is met.
Proper Adjustment Criteria:
• Bridge plate should just rest on
threshold plate (base plate).
• Should be an approximate 1/8˝
clearance between outboard end
of the saddle and the lower parallel
arm. See Photo F.
Tower 2 (Up) Switch Adjustment
Floor Position from Below Floor
1. Lower platform a minimum of 6˝
below oor level position using the
manual hand pump or pendant
control.
2. Turn switch adjustment screw coun-
terclockwise 3 full turns.
3. Press pendant UP switch (continue
pressing switch until platform stops).
4. When platform stops, turn switch
adjustment screw clockwise while
pressing the pendant UP switch.
Platform position will change. Ad-
just platform to meet criteria listed
for Tower 1 Switch "Proper Adjust-
ment Criteria".

Maintenance and Lubrication Schedule
Maintenance and
lubrication procedures
must be performed
as specied by a
BraunAbility autho-
rized service techni-
cian. Failure to do so
may result in serious
bodily injury and/or
property damage.
Proper maintenance is necessary to ensure safe,
trouble-free operation. Inspecting the lift for any wear,
damage or other abnormal conditions should be a part
of the transit agency daily service program. Simple
inspections can detect potential problems.
The maintenance and lubrication procedures specied
in this schedule must be performed by a BraunAbil-
ity authorized service representative at the scheduled
intervals according to the number of cycles.
BraunAbility dual parallel arm lifts are equipped with
hardened pins and self-lubricating bushings to de-
crease wear, provide smooth operation and extend the
service life of the lift.
When servicing the lift at the recommended intervals,
inspection and lubrication procedures specied in the
previous sections should be repeated. Clean compo-
nents and the surrounding area before applying lubri-
cants. Clean only with water, and then when cleaned,
lubricate as directed in the lubrication diagram. Do not
use solvents to clean.
LPS2 General Purpose Penetrating Oil is recom-
mended 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 installa-
tion procedures. Specied lubricants are available
from BraunAbility (part
numbers provided on
previous page).
All listed inspection,
lubrication and main-
tenance procedures
should be repeated at
750 cycle intervals fol-
lowing the scheduled
4500 cycle maintenance
procedures. These
intervals are a general
guideline for scheduling
maintenance procedures
and will vary according
to lift use and conditions. Lifts exposed to severe con-
ditions (weather, environment, contamination, heavy
usage, etc.) may require inspection and maintenance
procedures to be performed more often than specied.
Cycle Counter: NCL-2 Series lift models are
equipped with a cycle counter located on the top of
the pump module. This cycle counter allows the lift
attendant/operator to easily track the number of cycles
during daily inspections of the lift.
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
BraunAbility at 1-800-946-7513. One of our Aftersales
representatives will direct you to a BraunAbility autho-
rized service technician who will inspect your lift.
