916 Roll Groover
4. Properly support the pipe with pipe stands. Use two
pipe stands to groove pipe over 36".
WARNING Failure to properly support the pipe can
result in the unit tipping or the pipe falling.
5. Set up the Power Drive or Threading Machine per its
instructions in the flat level area. Confirm that the
REV/O-OFF/FOR switch is in the OFF position.
6. Position the foot switch so that the operator can
safely control the machine, roll groover and work-
piece. It should allow the operator to do the following:
• Stand with left hand on feed handle.
• Use the foot switch with his left foot.
• Have convenient access to the groover without
reaching across the machine.
Machine is designed for one person operation.
7. Check the unit to ensure it is operating properly.
• Flip the directional switch to FOR (Forward). Press
and release the foot switch. Check that the groove
roll rotates in a counterclockwise direction as you
are facing the groover. Have the power drive or
threading machine serviced if it rotates in the wrong
direction or if the foot switch does not control its
stopping or starting.
• Depress and hold the foot switch. Inspect the mov-
ing parts for misalignment, binding, odd noises or
any other unusual conditions that may affect the
safe and normal operation of the machine. If such
conditions are present, have the roll groover drive
serviced.
• Check the speed of the machine to ensure it rotates
under 58 RPM. Higher speed machine increases
the risk of injury.
• Flip the directional switch to REV (Reverse) (Except
1822-I and 535 Automatic machines). Press and
release the foot switch. Check that the drive roll
rotates in a clockwise direction as you are facing the
roll groover.
• Release the foot switch and flip the directional
switch to OFF.
8. Check the groove and drive rolls to ensure they are
the correct size.
Use of roll sets on both carbon and stain-
CAUTION
less steel pipe can lead to contamination of the stainless
steel material. This contamination could cause corrosion
and premature pipe failure. To prevent ferrous contami-
nation, use roll sets dedicated for stainless steel grooving.

Operation

WARNING
Keep hands away from grooving rolls. Do not wear
loose fitting gloves. Fingers can be crushed
between groove rolls, groove roll and pipe.
Keep hands away from ends of pipe. Do not reach
inside pipe. Do not touch groove while operating.
Burrs and sharp edges can catch and cut. Fingers
can be crushed between groove rolls or between
groove rolls and pipe.
Only groove pipe 8" (200 mm) or longer. Grooving
shorter than specified pipe can result in entangle-
ment and crushing injuries.
Do not use this roll groover with a power drive or
threading machine that does not have a foot switch.
Never block a foot switch in the ON position so it
does not control the machine. A foot switch pro-
vides better control by letting you shut off the
machine motor by removing your foot. If entangle-
ment should occur and power is maintained to the
motor, you will be pulled into the machine. This
machine has high torque and can cause clothing to
bind around your am or other body parts with
enough force to crush or break bones or cause
striking or other injuries.
Be sure that the roll groover, pipe, stands and
machine are stable. Be sure the roll groover is
properly set up and secured. This will help prevent
tipping of the equipment and pipe. Properly sup-
port the pipe. This will help to prevent the tipping of
the pipe and equipment.
Always wear eye protection. Wear steel toe footwear
to help protect from tipping tools and falling pipe.
Set up and operate the roll groover according to
these procedures to reduce the risk of injury from
machine tipping, entanglement, crushing, striking
and other causes, and to help prevent equipment
damage.

Pipe Preparation

1. Pipe ends must be cut square. Do not use cutting
torch.
2. Pipe out-of-roundness must not exceed the total O.D.
tolerance listed in groove specifications, Table III.
NOTE! Determine out-of-roundness by measuring max-
imum and minimum O.D. at 90 degrees apart.
3. All internal or external weld beads, flash or seams
must be ground flush at least 2" back from pipe end.
NOTE! Do not cut flats on gasket seat area.
