Getting Ready
(Reaming / Points to watch when threading)
-
After cutting the pipe with the pipe cutter, be sure to use the reamer
to chamfer the inside of the pipe before making a thread.
(
Figs. 17, 18)
-
Lift the die head and cutter out of the way.
Reamers with a shaft
-
Lower the reamer arm and set it in position on the carriage, then
push the reamer knob toward the pipe. (Fig. 17-1)
* Note:Reaming is possible without pushing the shaft when a pipe
is chucked long enough from the chuck.
-
Lock the reamer in position by turning the reamer handle counter
-clockwise.
(Fig. 17-2
）
-
Turn the machine on to start the pipe rotating. Then turn the carriage
handle to the right to move the reamer forward to engage the pipe.
Allow the pipe to rotate at least 1/2 a turn, then remove the reamer
from the pipe. That completes the reaming process.
(Fig. 18)
-
Do not use excessive force when pressing the reamer against
the pipe as this may scratch the pipe or even damage the
machine.
-
The reamer blade is extremely sharp. NEVER touch it with your
bare hands as you could be seriously injured.
