Lift Operation Safety
Keep operator and bystanders clear of area in which the lift operates.
Lift attendant must observe passenger at all times during lift operation.
Ensure adequate lighting exists in the lift operating area.
Whenever a wheelchair passenger (or standee) is on the platform, the:
• Passenger must be positioned at the center of the platform.
• Wheelchair brakes must be locked
• Bridge plate and roll stop must be up (vertical)
• Roll Stop latch must be fully engaged
• Passenger should grip both handrails (if able).
Wheelchair lift attendants should be instructed on any special needs and/or procedures
required for safe transport of wheelchair passengers.
Load and unload clear of vehicular trafc.
Do not attempt to load or unload a passenger in a wheelchair or other apparatus that
does not t on the platform area.
The lift attendant shall not ride on the platform with the passenger. The lift is intended
for use by a single passenger.
Do not overload or abuse. The load rating applies to both the raising and lowering
functions.
Use caution when operating this equipment out of doors during electrical storms or
similar electrical phenomena.
Use caution when operating this equipment in severe weather or environmental
conditions (fog, rain, snow, ice, dust, etc.)
Discontinue lift use immediately if any lift or vehicle interlock does not operate properly.
Do not operate or board the lift if you or your lift operator are intoxicated.

Position and secure (buckle, engage, fasten, etc.) the wheelchair-equipped occupant
seat belt (torso restraint) before loading onto the wheelchair lift platform.
Lift attendants must ensure that lift occupants keep hands, arms and all other body
parts within the lift occupant area and clear of moving parts.
Platform must be positioned at oor level (bridging position) when loading or unloading
in and out of vehicle.
Do not use platform bridge plate or roll stop as a brake. Stop and brake wheelchair
when loading onto the platform (manually stop and brake manual wheelchairs — stop
powered wheelchairs with the wheelchair controls).
Turn powered (electric) wheelchairs off when on lift platform.
Press the DOWN switch until the entire platform rests on ground level (lowered
fully) and the roll stop is fully unfolded (ramp position) before loading or unloading a
passenger at ground level.
Roll stop must be fully unfolded (ramp position) until front and rear wheelchair wheels
cross the barrier when loading or unloading at ground level.
Accidental activation of control switch(es) may cause unintended operation(s).
Maintenance and lubrication procedures must be performed as specied in this manual
by authorized (certied) service personnel.
Replace missing, worn or illegible decals.
Never modify (alter) a Braun Corporation lift.

in Figure C. Close the vehicle door(s).
Position lift as close to the door opening
as possible while maintaining a minimum
clearance of 12 mm between the lift and
the door or wall. See Figure D.
Lift-Tite®Latches: When checking ve-
hicle wall clearance - allow the lift to drift
fully into the Lift-Tite®latches to ensure
clearance (should drift occur). See Figure
F. Using the hand pump handle, stroke the
hand pump to stow the lift fully. Then open
the valve slightly (1/2 turn only), and allow
the Lift-Tite®latches to engage the vertical
arm pins fully. Close pump valve.

Side-to-Side Alignment: See Figure B on
previous page. The lift vertical arms and
platform should be perpendicular (90°) to the
vehicle oor and parallel (aligned) with the ver-
tical sides of door jamb. The vertical arms and
the parallel arms must clear the door opening
when the lift folds and unfolds.
Inboard-to-Outboard Alignment: See Figure
D. The vertical arms and parallel arms must be
aligned and parallel to each other. See Figure
D. The lift towers should be perpendicular
(90°) to the vehicle oor (except when base
plate wedges are used).
Step well Installations: It is not permissible
for the base plate to overhang the step well.
Base plate support must be constructed in the
step well for lift support. The structure must be
level with the existing oor and of equivalent
construction (structural strength).
Lift-Tite®Latches: When checking
vehicle wall clearance - allow the lift to
drift fully into the Lift-Tite®latches to
ensure proper clearances.

Adjustment Procedure:
Platform angle adjustment Allen
screws are provided on each
side of the platform (see photo
at right).
Turn adjustment screws clock-
wise to raise the outboard end
of the platform. Turn adjust-
ment screws counterclockwise
to lower the outboard end of
the platform.
Both adjustment screws must
be adjusted equally.
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).
Floor Level Adjustment:
Following platform angle adjust-
ment, set oor level positioning
as detailed in Tower Microswitch
Adjustment.
Check platform angle again
after performing Tower Micro-
switch Adjustment procedures.
1. The outboard end (toe) of
the platform must contact
the ground rst to ensure the
spring-loaded outer barrier
unfolds fully. See Figure B.
2. The inboard end (heel) of
the platform must lower fully
(vertical arms must contact
ground when fully lowered).
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 level.
Note the angle of the platform.
The platform at oor level
should have a slight upward
angle as shown in Figure C.
Adjust platform angle as de-
tailed below.

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 ad-
justment until criteria below is met.
Proper Adjustment Criteria:
• Bridge plate should just rest on base plate
cover. See Photo C.
• Should be an approximate 3 mm clear-
ance between outboard end of rotating
pivot slide arm saddle and the lower
parallel arm. See Photo B.
Tower 2 (Up) Switch Adjustment
Floor Position from Below Floor
1. Lower platform a minimum of 15.25 cm
below oor 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-

Tower 3 (Count) Switch Adjustment
Cycle Counter Switch
1. Position platform approximately 25 mm below
oor level position using the pendant control.
2. View the Tower 3 microswitch inside the lift
tower (see Photo D). Turn switch adjustment
screw counterclockwise until microswitch no
longer contacts the activation plate.
3. Observe the cycle count number on the LCD
display. Slowly turn switch adjustment screw
clockwise until the microswitch activates
(clicks) and the number on the cycle counter
LCD has changed.
Tower 4 (Fold) Switch Adjustment
Partial Fold
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 D). Turn the switch adjust-
ment 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 pressing the hand pendant
FOLD switch. The platform should not fold
(stow) with light pressure applied.
