975 Combo Roll Groover
4. Make sure that the groove roll has been retracted
enough to allow the pipe to be placed over the drive
shaft. If needed, turn the feedscrew counter-clock-
wise to raise the groove roll.
5. Place the pipe end over the driveshaft and set the
pipe down onto the pipe stand(s). Make sure the
pipe is stable.
Figure 8 – Placing Pipe Over Driveshaft and Flush To
Cover Plate
6. Adjust pipe and pipe stands so that the end of the
pipe is flush to the roll groover cover plate and that
the inside of the pipe contacts the top of the drive-
shaft (Figure 8). The centerline of the pipe and the
centerline of the drive shaft should be parallel to one
another. One way to do this is to level both the pipe
and the power drive/threading machine.
7. Slightly offset the pipe and pipe stands approxi-
mately
/
degree (about 1" over at 10 feet from the
1
2
roll groo v er) towards the operator. Proper alignment
of the pipe and roll groover helps to insure proper
tracking of the pipe while grooving. (See Figure 9.)
8. Turn the feedscrew clockwise to bring the groove
roll down in secure contact with the pipe. The
adjustment screw may need to be loosened (turned
counter-clockwise) to allow the groove roll to contact
pipe. Do not tighten any further until the groove
setting gauge has been used to properly adjust the
adjustment screw.
9. Evaluate the work area and determine if any barriers
are required to keep people other than the operator
away from the equipment and pipe. Guards or barri-
cades should be used to create a minimum of three
(3) feet of clearance around the power drive and
pipe. This "safety zone" prevents others from acci-
dentally contacting the machine or pipe and causing
tipping or becoming entangled in the rotating parts.
10. With dry hands, plug the machine into the properly
grounded outlet.

Do not wear loose clothing when operating the roll
groover. Keep sleeves and jackets buttoned. Do not
reach across the machine or pipe. Loose clothing
can become entangled in rotating parts and cause
crushing injuries.
Keep hands away from grooving rolls. Do not
groove pipes shorter than specified. Do not wear
loose fitting gloves. Fingers can be crushed be-
tween groove rolls or between groove roll and pipe.
Keep hands away from ends of pipe. Do not reach
