How to attach a mixer to a lift mechanism platform?

Hi~ We recently purchased and installed a heavy-duty mixer lift mechanism in a cabinet of our new kitchen build. Our problem is we don't know how to attach the mixer to the platform itself. There are no instructions supplied by the seller of the lift mechanism and I couldn't find anything on the Kitchenaid site. The mixer has rubber anti-skid knobs attached to the underside, but there are no pre-drilled holes for screwing it to a platform and no apparent way to clamp it to the stand. Has anyone completed a project like this already and if so, how did you attach the mixer to the platform?
