WARNING
• If the pipe should slip off the spindle flange surface,
turn the pipe threading machine "OFF" immediately
to stop pipe rotation. If rotation continues with the
pipe slipping out, the pipe will become detached
from the spindle and fall down, which may cause an
accident. (Fig. 19)
Loosen the handle and re-set the pipe.
If the pipe slips out, shift the pipe a little more.
2) After ensuring that the pipe will not slip out,
turn the handle according to the appropriate speed
indicated in Table 2 below. (Fig. 20).
If the pipe slip
cut, immediately
turn the switch
OFF
Spindle
Turn the handle at
the correct speed
CAUTION
• If the handle is turned unnecessarily quickly, damage
will be caused to the bearing and machine. Be sure
to turn it at the correct speed
3) By turning the handle, the groove is formed and
the adjusting nut approaches the adjusting plate.
If the handle does not turn smoothly when the
adjusting nut comes into close contact with the
adjusting plate, stop rotating the handle. (Fig. 21)

handle.
4) Wher, after stopping turning the handle, the pipe
continues one revolution, turn the threading machine
OFF and stop the pipe.
5) Turn the handle anticlockwise to raise the roller
holder to the full and detach .The pipe from the
spindle.
6) When using welded tubing, the tube or the
machine will produce a little jump as the weld bead
comes into contact with the roller-spindle. This is
perfectly normal.
7) When using the grooving machine with
20
Supertronic, use feed speed (slow) for tubing of 3"-
6" and reverse speed (fast) for tubing of 1-1.1/2".
