The following operations and conditions must be functionally veriﬁed 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 a Braun Corporation Product Support representative at

1-800-THE LIFT®.

• Vehicle movement is prevented unless the lift door is closed, ensuring the lift is stowed.

1. Verify on the pump module mounted interlock connector that the lift not stowed signal (pin 5) has an

open signal - OR - lift stowed signal (pin 7) has a +12 volt signal - OR - (pin 9) has a ground 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.

- Call Product Support

• The outer barrier will not raise if occupied.

- Refer to Outer Barrier Fold Pressure Adjustment procedures.

• Verify platform lighting when lift is deployed and pendant illumination when lift is powered.

1. Replace bulb(s) in the light housing.

2. Check fuse (5 amp fuse on circuit board; F13)

• A visual and audible warning 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

3. Replace the threshold strip switch

4. Reinstall the threshold warning plate

• Platform movement is prohibited beyond the position where the inner roll stop is fully deployed (up).

- Call Product Support.

• Lift platform movement shall be interrupted unless the outer barrier is deployed (up).

- Call Product Support.

1. Lower the platform to the ground level loading position.

2. Remove the pump cover.

3. Turn the adjustment screw (shown below) counter clockwise until the outer barrier does not raise

when the Up button is pressed.

4. Turn the adjustment screw clockwise in 1/4 turn increments until the outer barrier raises and fully

locks in position when the Up button is pressed. DO NOT turn the adjustment screw beyond this

position.

5. Verify the outer barrier will not raise when occuppied.

6. Reattach the pump cover.

1. Position the platform at the ﬂoor level loading

position.

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

platform folds completely (Note: Return the

platform to ﬂoor level position after each at-

tempt 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 adjust-

ment screw.

7. Verify the platform will not stow while occupied.

Adjusting the platform angle based on the

relationship of the platform at ground level

directly affects the angle of the platform

when positioned at ﬂoor level.

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).

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.

Century “NCL” Series:

Vista “NVL” Series:

The platform angle must be adjusted so

the outboard end of the platform (toe) is

angled down slightly when positioned at

ﬂoor level. See Figure D. The outboard

end of the platform must contact the

ground ﬁrst to ensure the spring-loaded

outer barrier unfolds fully.

Adjustment Procedures: Adjustment

Allen screws are provided on each side of

the lift platform for adjusting the platform

angle. Details and photos are provided

on the opposite page.

Base Plate Wedges: Installations where

base plate wedges are used require more

platform angle adjustment than normal.

Platform Stop Blocks: When ad-

justing platform angle, ensure both

stop blocks are making full contact

with the vertical arms (details on

opposite page).

Floor Level Adjustment: Follow-

ing platform angle adjustment, set

ﬂoor level positioning as detailed in

Platform Floor Level Adjustment
