end of the pipe. Apply slight pressure to the hand-
wheel to feed the reamer into pipe to remove the burr
as desired.

6. Remove foot from the foot switch.
7 . Move the REV/OFF/FWD switch to the OFF 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.

Head shown)
2. Close the die head.
3. Move the REV/OFF/FWD switch to the FWD position.
4. With both hands, grasp the carriage handwheel.

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 (Figure 24). 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. Do not run
machine in Reverse (REV) with dies engaged.
9. Remove foot from the foot switch.
10. Move the REV/OFF/FWD switch to the OFF position.
11. Turn the carriage handwheel to move the die head
past the end of the pipe. Raise the die head into po-
sition 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
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/FWD switch to 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
threading process. Left hand threading is possible with
300 Compact threading machine with REV/OFF/FWD
switch only. To cut left hand threads, left hand die heads
and dies are required.
1. Change the oil pump connections to allow oil flow
when the machine is run in reverse (REV). See
Figure 25. Be sure to return the connections to their
original configuration when returning to right hand
threading. Always replace cover before use.
