Measure the stoma to determine the Cutting Disc size required.
(Use the measuring rule as shown.)
Screw the Cutting Disc onto the Pliers. Position the Cutting Disc on the skin barrier/wafer, with the cutting edge against the wafer material not the adhesive cover, squeeze and slightly twist so the Cutting Disc clips out a neat hole with clean edges. Sometimes the cut is clean, but the adhesive cover does not cut. Simply peel the cut section from the wafer.
Attach the skin barrier and replace the pouch.
