To measure tubing for bending, use the center line of the tubing as shown. When establishing first measurement, make a REFERENCE mark for the starting point of measurement. In the example shown, a distance of 5" is desired between reference mark and 90˚ bend. Make a BEND mark at 5". Proceed to page 2 for bending procedure.
To make sure bends are made along the desired axis, mark the centerline on tubing before bending.

BEND
For common bending, open arms of tubing bender to position shown above. Insert tubing into correct size channel. Align "0" mark on roll guide with "0" mark on bending die. For a 90˚ bend, align the BEND mark made earlier with the "L" line on roll guide (for other angles less than 90˚, BEND mark must be adjusted to a different alignment on roll guide - see Fig. 3B). Note that the REFERENCE mark is below the tubing bender. Holding both handles of tubing bender, draw them together with a slow, steady motion to create bend. Bend is complete when "0" mark on roll guide is aligned with the desired angle mark on bending die. Release handles. Tubing may naturally try to spring back against the bend resulting in an angle less than desired. Check bend on an angle template or protractor to verify.

Sometimes it is necessary to bend tubing in a reverse position. For a 90˚ reverse bend, the BEND mark must align with the "R" line on roll guide. Complete bending procedure described on page 3.
