Roll Groover Inspection
WARNING
Before each use, inspect your roll groover and
correct any problems to reduce the risk of serious
injury from crushing injuries and other causes and
prevent roll groover damage.
Do not use this roll groover with a power drive/-
threading machine that does not have a foot switch.
1. If the roll groover is installed on a power drive or
threading machine, make sure that the machine is
unplugged and that the REV/OFF/FOR switch is in the
OFF position. Inspect and maintain the power drive/-
threading machine as directed in the machine’s oper-
ator’s manual. Failure to properly inspect and maintain
equipment can result in serious injury and property
damage. Make sure that that a foot switch is present
and properly operating. Do not use this roll groover
without a foot switch.
2. Clean any oil, grease or dirt from the roll groover,
including the carry handle, and the ratchet used to
activate the roll groover. This reduces the risk of
injury due to the groover or ratchet slipping from your
grip during use and allows easier inspection.
3. Make sure that the support arms are tight in the body
of the roll groover.
4. Inspect the roll groover for any broken, missing, mis-
arranged or binding parts or any other condition that
may prevent the safe and normal operation. Make
sure that the groove roll and drive shaft turn freely.
5. Check that the warning label is present and firmly
attached. See Figure 2 for the location of the warning
label.
6. If the drive shaft knurls are dirty, clean with a wire
brush. Dirty knurls can cause pipe slippage and track-
ing issues during grooving.
