VE272SFS Roll Grooving Tool
GROOVE DIAMETER STOP
ADJUSTMENT
The groove diameter stop must be adjusted
for each pipe/tubing size or change in wall
thickness. The groove diameter, which is
identified as the “C” dimension,” is listed un-
der the "Roll Groove Specifications" section,
starting on page 45. In addition, a label is af-
fixed to the tool, which lists the “C” dimen-
sions.
To achieve the proper diameter:
a.
Determine the diameter and thickness of
the pipe/tubing to be grooved.
b.
Locate the proper pipe diameter and
thickness on the pipe/tubing-size indicator
label of the depth stop. The depth stop can be
rotated for easy viewing.
1.
Back off the depth adjuster lock. Align
the top edge of the depth adjuster with the line
down and to the right of the proper size and
schedule markings, as shown above. Lock
the depth adjuster in position with the depth
adjuster lock.
2.
Insert a length of pipe/tubing over the
lower roll with the pipe/tubing end against the
lower-roll backstop flange.
3.
Prepare a trial groove. Refer to the
"Grooving Operation" section, starting on
page 20.
NOTICE
• To perform the following adjustments, use several
short, scrap sections of pipe/tubing that are the
proper material, diameter, and thickness to be
grooved. Make sure the scrap sections meet the
length requirements listed in Table 1 on page 12.
NOTICE
• The markings provide an approximate groove diam-
eter adjustment and are not exact groove diameter
settings. Variations in pipe/tubing OD and wall
thickness make it impossible to calibrate the groove
diameter stop exactly.
WARNING
Grooving rolls can crush or cut
fingers and hands.
• Before making any tool adjust-
ments, always turn the switch on
the power drive to the “OFF”
position, or disconnect the
power cord from the electrical
source.
• Make sure the guard is adjusted properly before
grooving pipe/tubing.
• Loading and unloading pipe/tubing will place your
hands close to the rollers. Keep hands away from
the grooving rolls and stabilizer wheel during opera-
tion.
• Never reach inside pipe/tubing end or across the
tool or pipe/tubing during operation.
• Always groove pipe/tubing in a CLOCKWISE direc-
tion only.
• Never groove pipe/tubing that is shorter than the
recommended lengths listed in this manual.
• Never wear loose clothing, loose gloves, or anything
that can become entangled in moving parts
