2. Loosen the hex nut on the adjustment screw (do not remove hex nut).
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 hex nut without moving the adjustment screw.
7. Verify the platform will not stow while occupied.

Adjustments to platform angle
may be required. Adjusting the
platform angle based on the rela-
tionship of the platform at ground
level directly affects the angle of
the platform when positioned at
floor level.
Unfold the lift and visually ex-
amine 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 platform angle must be
adjusted so there is a balance
between the angle at both posi-
tions (equal amount of angle).
Angle A should equal Angle B
as shown in Figure A.
Note: The outboard end of the
platform must contact the ground
first to ensure the spring-loaded
outer barrier unfolds fully. See
Figure B.
Adjustment Procedures:
Adjustment Allen screws are
provided on each side of the lift
platform for adjusting the platform
angle. See Figure C. Turn the
adjustment screw clockwise to
raise the outboard end of the
platform. Turn the adjustment
screw counterclockwise to
lower the outboard end of the
platform. Note: Both adjust-
ment screws must be adjusted
equally. Ensure both stop
blocks are making full contact
with the vertical arms. Apply
Loctite® to adjustment screws
following adjustment.
Floor Level Adjustment:
Following platform angle adjust-
ment, set platform floor level
positioning as detailed in Tower
Microswitch Adjustments.

Automatic Floor Level Positioning: GVL936
Series lifts feature automatic floor level positioning.
This feature eliminates the need for the lift operator
to position and stop the platform at vehicle floor
level when unfolding the platform from the stowed
position and when raising the platform from ground
level.
Floor Level Adjustments: Tower 1 (Unfold) and
Tower 2 (Up) microswitches control platform and
bridge plate positioning. Ensure floor level adjust-
ments are correct as outlined on page 7. Adjust
microswitches as needed only.
Floor Level Guidelines: When adjusting micro-
switches, bridge plate positioning and platform stop
block positioning must be viewed. A combination of
adjustments may be required to achieve a proper
balance. See Bridge Plate Positioning and Stop
Blocks below.
Stop Blocks: The platform stop blocks
(one per side) must be making full contact
with the vertical arms when the platform is at
floor level. See Photo A. Improper adjust-
ment of screw positioning can result in
lift damage.
Bridge Plate Positioning: The bridge
plate should rest solidly on the base plate.
There should be a smooth (level) transition
between the platform, bridge plate and the
base plate. Refer to Photos B and C.

Platform Angle Adjustments: Check platform
angle as outlined on page 5 when adjusting micro-
switches.
Adjustment Verification: Following the outlined
adjustment procedures, check floor level position
from stow position and from below floor level posi-
tion. The platform must stop automatically at floor
level when unfolding from stow position and when
raising from below floor level position. From the
stowed position, press the UNFOLD switch and hold
until the platform stops
at floor level. Once
stopped, ensure the
lift will fold when the
pendant FOLD switch
is pressed. Adjust the
switches as needed
per the guidelines in
Figure E.

Microswitch Adjustment Instructions:
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 clockwise 3
full turns.
3. Press pendant UNFOLD switch (continue
pressing switch until platform stops unfold-
ing).
4. When platform stops unfolding, turn switch
adjustment screw counterclockwise while
pressing the pendant UNFOLD switch.
Platform position will change. Repeat
adjustment until criteria below is met.
Proper Adjustment Criteria:
• The bridge plate should rest solidly on
the base plate (minimum of 1" overlap).
There should be a smooth (level) transi-
tion between the platform, bridge plate
and the base plate. See Photos B and C.
• The platform stop blocks (one per side)
must be making full contact with the
vertical arms when the platform is at floor
level. See Photo A.
Tower 2 (Up) Switch Adjustment:
Floor Position from Below Floor
1. Lower platform a minimum of 6" below floor
level position using the manual hand pump
or pendant control.
2. Turn switch adjustment screw counter-
clockwise 3 full turns.
3. Press pendant UP switch (continue press-
ing switch until platform stops).
4. When platform stops, turn switch adjust-
ment screw clockwise while pressing the
pendant UP switch. Platform position
will change. Repeat adjustment to meet
criteria listed in Tower 1 Switch "Proper
Adjustment Criteria" at left.
Adjustment Verification
Following adjustment procedures, verify
proper adjustment as detailed at left. Ad-
just the switches as needed per the guide-
lines in Photo A.

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.
W
ARNING
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 speci-
fied in this schedule must be performed by a Braun
authorized 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 inter-
vals, 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 compo-
nents exposed to contaminants when lowered to the
ground may require extra attention.
Lift components requiring grease are lubricated dur-
ing assembly procedures.
When these components
are replaced, grease must
be applied during installa-
tion procedures. Specified
lubricants are available from
The Braun Corporation.
All listed inspection, lubrica-
tion and maintenance pro-
cedures should be repeated
at “750 cycle” intervals
following the scheduled
“4500 Cycles” maintenance.
These intervals are a gen-
eral 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 proce-
dures to be performed more often than specified.
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.
