10.
If no more roll grooving will be performed
for a while, turn the power switch on the
side of the tool to the “OFF” position.
NOTICE
• The groove diameter must be within
specification for the diameter and wall
thickness of pipe. The groove diameter
should be checked and adjusted, as
necessary, to ensure that grooves remain
within specification.
GROOVING LONG PIPE LENGTHS
CAUTION
• For long pipe lengths, ensure that the
pipe stand is positioned properly to
minimize pipe-end flare.
• DO NOT install couplings on pipe that
exceeds the maximum allowable flare.
• This tool must be used ONLY for
roll grooving pipe designated in the
applicable “Tool Rating and Roll
Selection” section of this manual.
• Always refer to the applicable “Roll
Groove Specifications” table for details.
Failure to follow these instructions could
cause product failure, resulting in property
damage.
When roll grooving pipe that exceeds the
maximum length shown in Table 1, a roller-type
pipe stand must be used. The roller-type pipe
stand must be capable of handling the weight of
the pipe, while allowing the pipe to rotate freely.

Ensure that the tool is level. Refer to
the “Tool Setup” section for leveling
requirements.

3.
Position the pipe stand approximately
0 to
1/2
a degree to the left for the tracking
angle. Refer to the drawing above.
NOTE:
When pipe flare is excessive, right-to-left
tracking must be kept to a minimum. It
may be necessary to use less than
1/2
a
degree for the tracking angle.
4.
If the tool is properly set up in a level
position, but the back end of the pipe is
higher than the end being grooved, the
pipe may not track. In addition, excessive
flare may occur on the pipe end. Refer to
the “Tool Setup” section, and the drawings
above, for tool setup and pipe positioning
requirements.
5.
Before grooving, ensure that all instructions
in the previous sections of this manual
have been followed.
