1. With the REV/OFF/FWD switch in the OFF position
and the pipe stationary, use repeated and forceful
clockwise spins of the handwheel to loosen the pipe
in the chuck. Open the front chuck and the rear-cen-
tering device. Do not reach into chuck or centering
device.
2. Firmly grip the pipe and remove from the machine.
Carefully handle the pipe as the thread may still be hot
and there may be burrs or sharp edges.
1. After removing the pipe from the machine, clean the
thread.
2. Visually inspect thread. Threads should be smooth
and complete, with good form. If issues such as
thread tearing, waviness, thin threads, or pipe out-of-
roundness are found, the thread may not seal. Refer
to the Troubleshooting Chart for help in diagnosing
these issues.
3. Inspect the size of the thread.
• The preferred method of checking thread size is
with a ring gauge. There are various styles of ring
gauges, and their usage may differ from that shown
here.
• Screw ring gauge onto the thread hand tight.
• Look at how far the pipe end extends through the
ring gage. The end of the pipe should be flush with
the side of the gauge plus or minus one turn. If
thread does not gauge properly, cut off the thread,
adjust the die head and cut another thread. Using a
thread that does not gauge properly can cause
leaks.
