• The operator may need to apply slight force on the

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
