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
machine chucks.

Installing Pipe in Power Drive
1. Check to insure the cutter, reamer and die head is
swung to the rear of the carriage.
2. Mark the pipe at the desired length if it is being cut
to length.
3. Insert the pipe into the Power Drive 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 form the
front of the machine. Insert longer pipes through
either end so that the longer section extends out
beyond the rear of the Power Drive.
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 Power Drive. 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 Power Drive. This action
"hammers" the jaws tightly around the pipe.
