Instructions for use:
Select the proper size forming die and attach securely to driving
1.
gear. The slot in bottom of the forming die must be in positive
engagement with drive key. The square head screw must be tight.
(The crank can be used to tighten screw.)
Attach the crank to the drive shaft on side of bender’s base.
2.
The forming die should be turned so that the zero degree calibration
3.
mark faces crank handle. The straight side of die will then be parallel
with the base of bender.
Retract the roller bearing support assembly by lifting plunger and
4.
pulling away from forming die.
Insert tubing into groove of forming die and drop hook into place.
5.
Confine the tubing with the follow bar, and make sure that the zero
6.
degree calibration mark on the bar coincides with the same mark on

the forming die. (Note: It is important that the follow bar be placed in
operating position with the correct tube size marking on top.)
Lift the plunger on the roller bearing support assembly and move
7.
forward until contact is made with the follow bar. (When bending
small size tubing, support assembly will not quite touch follow bar.)
Follow bar, tube and forming die will now be in contact with each
other.
Turn the crank clockwise slowly and allow the roller bearing support
8.
assembly to retract until it falls into the predetermined position and
locks itself securely. This can be noted by the dropping of the
plunger. Then continue to turn crank clockwise until the desired
degree of bend is attained.
To remove bent tube, simply reverse the procedure until the pressure
9.
is relieved, then retract the roller bearing support assembly.
The worm gear housing is completely filled with lubricant and needs to be inspected only at reasonable intervals. However, it is highly desirable to
lubricate all other moving parts, particularly the roller bearing support assembly.
