2.
Locate the proper size and schedule on the
pipe size indicator above the hydraulic power
cylinder. It is rotatable for easy viewing.
3.
Back off the depth adjuster lock. Align the
depth adjuster with the proper size and sched-
ule as shown. Lock the depth adjuster in posi-
tion with the depth adjuster lock.
4.
Set the selector valve on the power switch
side of the tool to the color that matched the
pipe size and schedule number color (red or
black) of the pipe size indicator.
NOTICE
The markings provide an approximate groove
diameter adjustment and are not “exact” groove
diameter settings. Variations in actual pipe O.D.’s and
wall thicknesses make it impossible to calibrate the
diameter stop exactly.
5.
Using a piece of scrap pipe or short piece of
pipe (refer to the Groovable Pipe Lengths Table
on page 9) of the diameter and wall thickness
to be grooved, place the pipe over the lower roll
with the pipe end against the lower roll back
stop flange.
6.
Prepare a trial groove. To do so, follow the
Grooving Operation procedures outlined on
page 16.
NOTICE
The selector valve only affects the maximum pressure
at which the upper roll forms the groove. It does not
affect the rate at which the roll retracts from the pipe
at the completion of the groove.
Ram pressure during the formation of the groove can
have a significant effect on pipe end flaring. The above
recommended settings will produce accurate grooves
in most situations. When operating in the high ram
pressure or “red” setting, if excessive pipe flaring or
stalling of drive motor occurs, changing the selector
valve setting to low or “black” will usually correct the
condition.
Grooving rolls can crush or cut
fingers and hands.
• Keep hands away from
grooving rolls and stabilizer
wheel.
• Never reach inside pipe end
or across the tool or pipe
during operation.
• Always groove pipe in a clockwise direction only.
• Never groove pipe shorter than what is
recommended.
• Never wear loose clothing, loose gloves, or jewelry
while operating tool.
