Threading with 11R Die Heads

1. For 11/2" - 2" 11-R Die Heads, push die heads, spline end first, squarely into the threader until the

spring engages securely. For 1/2" - 11/4" 11R Die Heads, rotate adapter cap clockwise, then push die

heads into adapter spline end first, then release the adapter cap to hold die head (fig 3 & 4).

NOTE! Installation can be made from only one side of the threader.

2. If possible, secure the pipe in a portable tristand vise or a bench vise.

To prevent tipping, long lengths of pipe should also be supported with pipe stand.

3. Be sure the Oiler is properly filled with Thread Cutting Oil. We suggest specific oiler for this purpose.

4. Position Support Arm on pipe so end of support arm is in line with end of the pipe (Figures 5). Make

sure jaws squarely contact pipe and tighten handle firmly to prevent slipping of the jaws.

Note! To avoid serious injury from losing control of the threader, a support arm should be used

when threading 3/4" or larger pipe.

When threading pipe less than 3/4" in size without a support arm, hold onto the threader firmly

with one hand to exert pressure against the handle forces developed during threading.

5. Place Die Head over end of pipe and insert post of support arm through notch in gear case.

6. Simultaneously actuate the ON/OFF switch and exert pressure against the Die Head with the palm of

free hand to assist in starting thread. Apply plenty of thread cutting oil to the dies during threading. This

will reduce the torque required to thread and improve the thread quality (Figure 6).
