2. Mark the pipe at the desired length if it is being cut to length.
3. Insert the pipe into the Threading Machine so that the end to be worked or the cutting mark
is located about 12 inches to the front of the speed chuck jaws
(Fig 1)
.
4. Insert workpieces less than 2 feet long from the front of the machine. Insert longer pipes
through either end so that the longer section extends out beyond the rear of the Threading
Machine.
Tighten the rear centering device around the pipe by rotation of the handwheel at the rear of
the Threading Machine. This prevents movement of the pipe that can result in poor thread
quality.
6. Secure the pipe by using repeated and forceful counterclockwise spins of the speed chuck
handwheel at
the front of the Threading Machine. This action “hammers” the jaws tightly
around the pipe.
