sleeve aligning the start of bend with the”0” mark on the die.
6.1.15 Select a speed and follow the above steps and begin
ratcheting the machine until the you feel tension on the pull lever, as
your tubing just begins to bend. position your pointer to the “0" on the
degree dial, this will compensate for most of your “spring back"
6.2 Die Selection and Installation
Damaged or worn tooling should be replaced before attempting to
bend material. This will ensure that bends are correct and provide a
longer life to machine components.
6.2.1 Before any bending can take place. the proper die set must be
chosen to match the material being bent. (EX) 1-1/2” diameter tubing
requires a die set marked 1-1/2” tube.
6.2.2 Two different types of dies are available. 120 deg and 240 deg
dies. The 240 deg dies allow you to bend to a full 180 degrees. and
the 120 deg will allow you to bend to approx 120 degrees
6.2.3 “Pipe” and “Tube” are not the same, so all of the dies will be
marked in actual outside diameter of the material, and will relate to
"Tube"
Caution: When installing large dies use another person to help load
into the machine.
1) To install the die. remove all of the pivot pins and install them in
their storage area to the left of the ratchet wheel
