3.4Installing the Mounting Hardware
For ease of installation, install the mounting bracket hardware onto the rigidizer bar first. The MX1 back cushion can be installed onto the rigidizer bracket after the mounting hardware is installed.
1.Remove any existing wheelchair back, back upholstery or back cane hardware. Refer to the user manual that came with the wheelchair or back upholstery.
2.Loosen the compression bar hardware A inside the rigidizer bracket B.
WARNING
DO NOT adjust the center screw in the rigidizer bracket. The center screw C is designed only to hold the compression bar in place during installation. Adjusting this screw may prevent the compression bar from tightening properly onto the back cane.
The compression bar hardware must be loosened to ensure the rigidizer bracket rests flush against the rigidizer bar D.
The rigidizer bar is shown in the illustration for reference only.
