300 Compact Pipe and Bolt Threading Machine
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
WARNING
the 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 pre-
vents 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 (Figure 7).

WARNING
balance and to safely keep control of the machine and
tools.

ously until the pipe is cut. Do not force the cutter into
the workpiece.
9. Release the foot switch and remove your foot from the
housing.
10. Swing pipe cutter back to the UP position.
