Figure 3.1.A.4 Figure3.1.A.5 Note: Several expanding actions may be necessary to effectively expand the end of the tube for the fitting/connector to slide in. Each time you expand the tubing remember to rotate the tubing 90 degrees on the jaws. - Page 8 • The CRD201 expansion operation is designed to let the operator expand each piece of tubing twice.

This ensures that the tubing is expanded in a uniform fashion, and not deformed in only one direction.
