Operation Using
Machine-Mounted Tools
WARNING
Do not wear gloves or loose clothing when operat-
ing Threading Machine. Keep sleeves and jackets
buttoned. Do not reach across the machine or pipe.
Do not use this Threading Machine if the foot switch
is broken or missing. Always wear eye protection to
protect eyes from dirt and other foreign objects.
Keep hands away from rotating pipe and fittings.
Stop the machine before wiping pipe threads or
screwing on fittings. Allow the machine to come to
a complete stop before touching the pipe or ma -
chine chucks.
Do not use this machine to "make-on" or "break
off" fittings. This practice is not an intended use of
this Threading Machine.
Installing Pipe In Threading Machine
1. Check to insure the cutter, reamer and die head are
swung to UP position.
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.
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.
To avoid equipment tip-overs, position the
WARNING
pipe supports under the workpiece.

5. Tighten the rear centering device around the pipe by
using a counterclockwise 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 hand-
wheel at the front of the Threading Machine. This
action "hammers" the jaws tightly around the pipe.
Cutting Pipe With No. 360 Cutter
1. Swing reamer and die head to UP position.
2. Move pipe cutter DOWN onto pipe and move carriage
with handwheel to line up cutter wheel with mark on
pipe.
3. Tighten cutter feed screw handle on pipe keeping
wheel aligned with the pipe.
4. Assume the correct operating posture .
This will allow you to maintain proper bal-
WARNING
ance and to safely keep control of the machine and tools.
• Be sure you can quickly remove your foot from the
foot switch.
• Stand facing the directional switch.
• Be sure you have convenient access to directional
switch, tools and chucks.
• Do not reach across the machine or workpiece.
