• Slightly increase the offset of the pipe towards the
operator (increase from
Figure 9).
• The operator may need to apply slight force on the
pipe while grooving to maintain tracking. This is usu-
ally only needed on shorter sections of pipe. To do
this, the operator should wear a leather glove in
good condition and cup their hand around the middle
of the pipe as shown in Figure 13 . This may require
that the stand to which the power drive/threading
machine is mounted be fixed to the floor to prevent
movement during grooving. To prevent crushing
injuries, keep hand away from the groove roll and the
ends of the pipe, and do not groove pipe shorter
that recommended.

Maintain Tracking
• Additionally, see the Troubleshooting Section for a
complete list of reasons for and solutions to tracking
issues.

Machine and Work Area Set-Up
For In Place Applications
WARNING
Always wear eye protection to protect your eyes
against dirt and foreign objects. Wear steel toe
footwear to protect feet from tipping and falling
pipe and tools. When working in place, wear a hard
hat.
Set up roll groover and work area according to
these procedures to reduce the risk of injury from
machine tipping, crushing and other causes, and
prevent roll groover damage.
1. Locate a work area that has the following:
• Adequate lighting.
• No flammable liquids, vapors or dust that may ignite.
If present, do not work in area until sources have
been identified and corrected.
• Clear, level, stable and dry location with adequate
space for all of the equipment and the operator.
2. Clean up the work area prior to setting up any equip-
ment. Always wipe up any oil that may be present.
3. Inspect the pipe to be grooved and confirm that the
975 Combo Roll Groover is the correct tool for the job.
The 975 Combo Roll Groover is designed to groove
schedule 10 and 40 steel, aluminum, and PVC pipe in
1 1 / " to 6" sizes. It is also designed to groove 1

steel pipe. With a roll set change, it can be used to
groove 2" - 8" Type K, L, M and DWV copper tube.
The 975 Combo Roll Groover can be used for in
place applications (pipe that is in place or mounted in
a vise) or with a RIDGID 300 Power Drive or 300
Compact Threading Machine for power ed applications
on the job site. The 975 Combo Roll Groover is not
intended for production type applications.

enough space for the 975 Combo Roll Groover to fit
and be operated. The roll groover will orbit around the
solidly mounted pipe and requires:
