9. Keep your hands away from the rotating pipe. Make
sure the carriage does not hit the machine. When
the thread is complete, open the die head (if the die
head does not open automatically). Do not run ma -
chine in Reverse (REV) with dies engaged.
10. Remove foot from the foot switch.
11. Move the REV/OFF/FOR switch to the OFF posi-
tion.
12. Turn the carriage handwheel to move the die head
past the end of the pipe. Raise the die head into
position up away from the operator.
13. Remove the pipe from the machine and inspect the
thread. Do not use the machine to tighten or loosen
fittings on the thread.

Threading Bar Stock/Bolt Threading

Bolt threading is similar to the pipe threading process. The
stock diameter should never exceed the thread major
diameter.
When cutting bolt threads, the correct dies and die head
must be used. Bolt threads may be cut as long as need-
ed, but make sure the carriage does not hit the machine.
If long threads are required:
1. At the end of carriage travel, leave the die head
closed, remove foot from the foot switch and move the
REV/OFF/FOR switch in the OFF position.
2. Open the chuck and move the carriage and work-
piece to the end of the machine.
3. Re-chuck the rod and continue threading.

Left Hand Threading

Cutting left hand threads is similar to the right hand thread -
ing process. To cut left hand threads, left hand die heads
and dies are required. Latch the die head in place (Figure
24). Run machine in Reverse (REV) while threading.

Beveling Pipe

1. Install the beveling dies as per "Inserting/Changing
the Dies" procedure.
Bevel cutting die (marked "2") must go into the num-
ber 2 die head slot. Guide dies are not marked and
are used in the 1, 3 and 4 die head slots. Refer to the
respective die head instructions for information on die
insertion.
2. For 714 and 914 die heads, set up for NPSM/BSPP
straight threads.
3. Follow the Threading Machine instructions for thread-
ing pipe.
Move the die head into threading position and close
the die head. Move the carriage to bring the dies in
contact with the pipe and apply slight force to form the
desired bevel. In some cases, the size may need to
be adjusted slightly (OVER or UNDER) so that the
guide dies ride on the pipe outside diameter.

Removing Pipe from the Machine

1. With the REV/OFF/FOR 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.
