Machine Inspection

WARNING
Do not use this Roll Groover with a power drive or
threading machine that does not have a foot switch.
To prevent serious injury, inspect your Roll Groover
and machine. The following inspection procedures
should be performed on a daily basis.
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 all bolts holding the Roll Groover and hy-
draulic pump to the base are tight.
5. Drive bar must be centered and securely held in the
front chuck.
6. Check that guard mounted to the roll groover is in
place (Figure 3) .
WARNING Do not operate Roll Groover with guard
removed. Exposure to moving grooving rolls may re-
sult in fingers being crushed.
7. Inspect the Roll Groover and machine for any broken,
missing, misaligned or binding parts as well as any
other conditions which may affect the safe and normal
operation of this equipment. If any of these conditions
are present, do not use the Roll Groover until any
problem has been repaired.
8. Lubricate the Roll Groover if necessary according to
the Maintenance Instructions.
9. Use groover rolls and accessories that are designed
for your Roll Groover and meet the needs of your ap-
plication. The correct groover tools and accessories
allow you to do the job successfully and safely. Ac -
cessories suitable for use with other equipment may
be hazardous when used with this Roll Groover.
10. Clean any oil, grease or dirt from all equipment han-
dles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.

11. Inspect the groove rolls to insure they are not dam-
aged or worn. Worn groover rolls can lead to pipe
slippage and poor quality grooves.

Machine and Work Area Set-Up

To prevent serious injury, proper set-up of the machine
and work area is required. The following procedures
should be followed to set-up the machine:
1. Locate a work area that has the following:
• Adequate lighting
• No flammable liquids, vapors or dust that may ignite.
• Grounded electrical outlet
• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
• Dry place for machine and operator. Do not use
the machine while standing in water.
• Level ground
2. Clean up the work area prior to setting up any equip-
ment. Always wipe up any oil that may be present.
3. Place machine on a flat level surface. Be sure the ma-
chine, stand and groover are stable.
4. Properly support the pipe with pipe stands. See Chart
"A" for maximum pipe lengths to be grooved with
one stand.

5. Make sure FOR/OFF/REV switch is in the OFF posi-
tion.
6. Position the foot switch so that the operator can
safely control the machine, roll groover and work-
piece. It should allow the operator to do the following:
• Stand facing the hydraulic pump.
• Use the foot switch with his left foot.
• Have convenient access to the groover and hydrau -
lic controls without reaching across the machine.
Machine is designed for one person operation.
7. Plug the machine into the electrical outlet making
sure to position the power cord along the clear path
