5. Turn carriage handwheel to move the reamer to the
end of pipe. Apply slight pressure to the handwheel
to feed the reamer into pipe to remove the burr as
desired.
6. Remove foot from the foot switch.
7 . Move the ON/OFF (I/O) switch to the OFF (O) position.
8. Move the reamer up away from the operator.

Threading Pipe

Due to differing pipe characteristics, a test thread should
always be performed before the first thread of the day or
when changing pipe size, schedule or material.
1. Lower the die head into the threading position. Con-
firm that the dies are correct for the pipe being
threaded and properly set. See the "Die Head Set-Up
and Use" section for information on changing and
adjusting dies.
2. Close the die head.
3. Move the ON/OFF (I/O) switch to the ON (I) position.
4. With both hands, grasp the carriage handwheel. See
Figure 13.
5. Depress the foot switch.
6. Confirm cutting oil flow through the die head.
7 . Turn carriage handwheel to move the die head to the
end of the pipe. Apply slight force to the handwheel
to start the die head onto the pipe. Once the die head
starts threading the pipe, no more force is required on
the carriage handwheel.
8. 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.
9. Remove foot from the foot switch.
10. Move the ON/OFF (I/O) switch to the OFF (O) posi-
tion.

11. 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.
12. 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
needed, but make sure the carriage does not hit the ma-
chine. 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
ON/OFF (I/O) switch to the OFF (O) position.
2. Open the chuck and move the carriage and workpiece
to the end of the machine.
3. Re-chuck the rod and continue threading.

Removing Pipe from the Machine

1. With the ON/OFF (I/O) switch in the OFF (O) 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.
