Certification Checklist Diagnostic Procedures 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 referenced procedures to correct the problem or contact a Braun Corporation Product Support representative at 1-800-THE LIFT®. • Vehicle movement is prevented unless lift door is closed, ensuring the lift is stowed. 1.
Platform Fold Pressure Adjustment 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 attempt to fold the platform). 5.
Platform Angle Adjustment 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. Millennium “NL” Series Figure C 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.
Platform Angle Adjustment Adjustment Allen screws are provided on each side of the lift platform for adjusting the platform angle. Adjust platform angle as specified on previous page. To raise the outboard end of platform - turn adjustment screw clockwise. Note: Both adjustment screws must be adjusted equally. Apply Loctite® to adjustment screws following adjustment. To lower the outboard end of platform - turn adjustment screw counterclockwise.
Platform Floor Level Adjustment Before setting floor level position: tion if unable to stop platform when powering lift. • Adjust platform angle as detailed on page 6. 2. Turn Lift Power switch Off. • Ensure both stop blocks are making full contact with vertical arms (details on page 7). 3. Press Floor Position Set button (located between pump housing and lift tower). Floor Level Adjustment: 4. While pressing the Floor Position Set button, turn the Lift Power switch On. 1.
Bridging Microswitch Adjustment Adjustment Screw Bridging Microswitch: Bridging Microswitch G H The bridging microswitch is located at the bottom of the right (front) vertical arm. See Photos A and B. An adjustment screw is built into the platform stop block. The bridging microswitch will be deactivated if the outboard end of the platform contacts the unloading surface before the inboard end while the DOWN switch is pressed.
LCD Lift Codes To better understand the Braun LCD Trouble shooting display you must first understand the numbers that appear on the screen. There are Flashing Codes, Solid Error Codes, and Solid Normal Operational Codes. Flashing Codes #65-89: About 10 seconds after an operation has stopped there are a set of scrolling flashing numbers that indicate whenever a particular sensor or switch has been activated. These numbers will start at number 65 and scroll up to number 89, then start the sequence over.
LCD Lift Codes Listed below are codes that the lift controller outputs during lift operation. The codes will be displayed on an LCD screen located on the lift control board inside the pump module. See the Manual Operating Instructions in the operator's manual for pump cover removal instructions.
