2. Precautions when using the Portable Groover H
㧍
WARNING
1) Mount the groover on specified pipe threading machines that have been tested for
safety. (See Table 1, Pg. 5) Do not attempt to use on any other machines.
The correct rotational direction is the direction when threading.
2) Use the rollers that match the pipe. (Refer to Table 2 on Pg. 6)
ޓ
The standard roller set can be used only for 2"- 6" steel pipe (SCH 10-40). It cannot be used
for thin wall stainless steel pipes or pipes of a different size. Since applicable sizes are
marked on the rollers, replace the rollers according to the size of the pipe.
3) Never touch rotating parts or workpieces.
ޓ
To prevent injury to hands and fingers, do not touch rotating rollers and pipes with your
hands.
4) Attach the mount kit that matches the pipe threading machine to be used. (See Table 1, Pg. 5)
If a different type of mount kit is attached, it with not be possible to set it on the pipe
threading machine correctly.
5) Make sure the threading machine rotates in the right direction.
The direction for threading is the right direction. If it is in the reverse direction, the pipe will
fall out, which can be very dangerous.
6) The pipe must be set correctly. (See Fig. 14, Pg. 10)
Set the pipe so that it is in the right direction and at 0.5
q
to the axis of the machine's
main shaft.
If it is thrown into reverse, the pipe will fall out, which can be very dangerous.
7) Make sure you operate the handle on the hydraulic pump correctly. (See Table 5, Pg. 13)
If you operate the handle too quickly, the pipe may be distorted and/or the machine will
be damaged.
8) After completing the groove, be sure to check on the size of the groove with a groove gauge
or calipers, etc. (See Table 6, Pg. 13, Roll Groove Standard Machining Size)
9) Be sure to place the pipe threading machine and pipe stand on a stable, flat surface.
Avoid using the pipe threading machine and pipe stand in an unstable position or
the machine and pipe may fall over.
