1 O.Chamfering
After cutting the pipe with the pipe cutter, be sure to use the reamer to chamfer
the inside of the pipe before cutting threads.
(1) As the die head and cutters will not be used when chamfering, lift them out
of the way.
(2) Pull up the reamer knob to place the reamer in the chamfering position.
(3) Set the switch to the ON position to start the pipe rotating, then use the feed
handle to place the reamer against the pipe. When the pipe has made at least
one complete revolution, remove the reamer from the pipe. This completes
the chamfering process. (Fig. 20)
A
CAUTION
Do not use excessive force to press the reamer against the pipe.
This may produce harmful scratches in the pipe or damage the unit.
The reamer blade is extremely sharp.
NEVER touch it with your bare hands, as you may be seriously injured.

Threads
1 1 .Carriage Protection Mechanism
Attempting to cut threads on pipes that are too short may cause the
carriage to strike the headstock, warping or otherwise damaging the
unit. Accordingly, the unit is equipped with a carriage anti-collision
mechanism. This mechanism protects the machine by automatically
stopping the motor just before the carriage strikes the headstock.
(1) As the carriage nears the headstock, a rod is automatically pushed
forward.
(2) If the carriage moves any closer, the rod presses the switch, turning
off the machine just before the carriage strikes the headstock.
(3) The pipe end allowance is too short, so increase the end allowance
and clamp the pipe again.
(See "Attaching Short Pipes for Thread Cutting" on Pg. 10.)
A
CAUTION
·
Start the thread cutting process with the carriage to the right of the
red line on the front support bar.
