Rear beam cut-outs
It is often necessary to create cut outs in the rear beam to provide space for the platform arms when the
platform is in the upper position. The size of the cut outs depends on the calculated installed dimension "A",
see illustration below.
1. Measure and mark the location and depth of the cut outs on the rear beam. The two cut outs must be
centred on the rear beam, i.e. both cut outs must be an equal distance from the mid-point of the beam.
2. Cut along the markings.
3. Grind away any burrs or sharp edges.
