Remove the cabinet door. The lifting mechanism will be in two pieces, one for the left side of the cabinet and one for the right.
With the lift arm extended, hold the right piece of the lifting mechanism up to the right side of the cabinet. Approximate the position you would like the mixer lift to be installed. Make sure the mounting bracket is level, and measure out its position in the cabinet. Using a pencil, mark out the holes in the mounting bracket.
Refer back to the mixer lift measurements, and position the left lift mechanism according to these measurements with both lift arms extended. Level out the left mounting bracket (Image 1). Span a level over both lift arms to make sure the shelf will be level (Image 2). Mark out the holes in the left mounting bracket, drill pilot holes and screw the left lift mechanism into place.
