Machine Inspection and Set-Up

WARNING
Do not use this Roll Groover with a power drive that
does not have a foot switch.
To prevent serious injury, inspect your Roll Groover
and power drive. The following inspection proce-
dures should be performed on a daily basis.

Inspecting 920 Groover

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
stabilizer to the base are tight. Make sure all screws
holding the pump to the Roll Groover 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 and operating properly (See Page 11).
WARNING
removed. Exposure to moving grooving rolls may result
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
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
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 slip-
page and poor quality grooves.

Machine Set-Up

1. Properly support pipe with pipe stands. Use pipe
stands rated for the pipe size to be grooved.
NOTE! Six inch pipe and smaller should be supported
with No. VJ-99 Pipe Stand. For lengths less
than 36", one stand can be used; for lengths
greater than 36", two stands should be used.
Six inch pipe and larger can be supported on
the RJ624 pipe stand. One stand can be used
for lengths less than 8 feet. When one stand is
used, the pipe should be centered on the stand
so that the center of gravity of the pipe is over
the center of the stand.
WARNING
result in the unit tipping or the pipe falling.
2. Make sure FOR/OFF/REV switch is in the OFF posi-
tion.
3. 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 hy-
draulic controls without reaching across the ma-
chine.
