NOTICE
both carbon and stainless steel pipe can lead to con-
tamination of the stainless steel material. This contami-
nation could cause corrosion and premature pipe failure.
To prevent ferrous contamination of stainless steel pipe,
use roll sets dedicated for stainless steel roll grooving.
Alternately, a stainless steel wire brush may be used to
thoroughly clean the roll set when switching between
materials.

Pipe Preparation

These are generalized instructions. Always
NOTICE
follow grooved coupling manufacturer's specific recom-
mendations for pipe end preparation. Failure to follow
the grooved coupling manufacturer's recommendations
may lead to an improper connection and cause leaks.
1. If grooving in place on an existing piping, make sure
that the system has been depressurized and emptied
of contents. Know what the contents are and any
hazards associated with them.
2. Cut pipe to proper length.
Make sure pipe end is cut square and free of burrs.
Burrs can catch or cut gloves or fingers during groov-
ing. Cut off method and large burrs can effect the
quality of the groove made and the tracking of the
Groove. Do not attempt to groove pipe that has been
cut with a torch.
3. All internal/external weld beads, flash, or seams must
be ground flush at least 2" back from the end of the
pipe. Do not cut flats into gasket seat area, this could
cause leaks.
4. Remove all scale, dirt, rust and other contaminants at
least 2" back from the end of the pipe. Contaminants
can clog the drive knurls and prevent proper driving
and tracking of the pipe while grooving.
5. Make sure that the pipe to be grooved is solidly
mounted. The pipe must be able to withstand the
weight of the roll groover (28 pounds), and the force
and torque required for grooving without moving.
For pipe that is in place, it may make sense to re move
the pipe and groove at a pipe vise. In other cases, it
may be necessary to add other temporary or perma-
nent pipe supports. When using a pipe vise, make
sure that it is secure and will not tip during use. For
longer lengths of pipe, use appropriate pipe stands to
support the extra length.

Mounting The Roll Groover To The Pipe

1. Confirm that the 975 Combo Roll Groover has been
inspected and has the appropriate roll set installed.
Make sure that the support arms are tight in the body
of the roll groover or remove them completely for
better access in tight spaces. Next, install the ratchet
into the feedscrew and install the extension into the
manual drive square at the back of the roll groover.
Make sure both the ratchet and extension are secure-
ly installed.
2. Make sure that there is enough space between the
groove roll and drive shaft for the pipe wall. If needed,
turn the feedscrew counter-clockwise to retract the
groove roll.
3. Securely grasp the roll groover. Do not lift with the
ratchet. Place the driveshaft into the pipe and make
sure that the cover plate is tight to the end of the pipe
(Figure 14) . Tighten the feedscrew to bring the groove
roll into contact with the outside of the pipe. Once the
feedscrew is hand tight, use the ratchet to tighten the
feedscrew an additional
groover is securely attached to the pipe and the
cover plate is flush to the end of the pipe. If not,
repeat procedure. Always make sure groover is
secure when used in place to prevent it from falling.
