With the aid of a 1/100 plastic thickness gauge, check the gap
between the portal contact edge and the guide slide (1). The
gantry must lie flush with the guide slide, leaving no room in-
between for the thickness gauge.
If this is not the case, dismantle the gantry and clean the
contact surfaces again thoroughly (with the dressing stone).
