Pre-Operation Inspection

WARNING
Do not use this roll groover with a power drive/-
threading machine that does not have a foot switch
Before each use, inspect your roll groover and cor-
rect any problems to reduce the risk of serious
injury from crushing injuries and other causes and
prevent roll groover damage.
1. If installed on a machine, place the machine switch in
the OFF position and unplug.
2. Clean any oil, grease or dirt from the roll groover,
including the pump handle. This aids inspection and
helps prevent the machine or control from slipping
from your grip.
3. Inspect the roll groover for the following:
• Proper assembly, maintenance and completeness.
• Broken, worn, missing, misaligned or binding parts.
• Presence and readability of the warning label (see
Figure 5).
• Condition of the groove roll and drive roll. If the
drive roll knurls are dirty, clean with a wire brush.
Dirty or worn knurls can cause pipe slippage and
tracking issues during grooving.
• Any other condition which may prevent safe and
normal operation.
• If any issues are found, do not use the roll groover
until the issues have been repaired.
