WARNING
1. Make sure machine is unplugged and the directional
switch is set to the OFF position.
2. Make sure the foot switch is present and attached to
the machine.
3. Inspect the power cord and plug for damage. If the
plug has been modified, is missing the grounding
pin or if the cord is damaged, do not use the machine
until the cord has been replaced.
4. Make sure the Roll Groover is properly attached to the
power drive or threading machine. Drive bar must be
centered and securely held in the front chuck.
5. Inspect the Roll Groover for any broken, missing,
misaligned or binding parts as well as any other con-
ditions which may affect the safe and normal opera-
tion of this equipment. If any of these conditions are
present, do not use the Roll Groover until any problem
has been repaired.
6. Lubricate the Roll Groover if necessary according to
the Maintenance Instructions.

application. The correct groover tools and acces-
sories allow you to do the job successfully and safe-
ly. Accessories suitable for use with other equipment
