SECTION VI – GROOVING ThE PIPE OR TUBE (MODELS 1007 & 3007)
A. STEEL PIPE
1. Recheck for correct pipe set-up and position on the bottom roll
and adjust as required. Close the relief valve on the hydraulic hand
pump and increase pump pressure to 400 psi. (200 psi for Sch. 10)
MODEL 3007 ONLY – Extremely Important
Check to see that the Ridgid*
300 drive directional
switch is set to "reverse"
position (clockwise rotation
of the pipe looking at the
front of Groover.)
Pipe must be square on
ends.
Burrs or torch slag must
be removed. Any pipe manufacturing seam, on inside or outside
of pipe, must be removed.
2. Start the drive motor by
depressing the foot switch
to rotate the pipe. Assure
that the pipe is tracking
firmly against the back of
the bottom roll.
3. With the pipe rotating,
increase grooving force
by slowly pumping the
hydraulic pump handle to
raise pump pressure.
Do not pump too fast.
Using the pressure gauge
mounted on the hydraulic
ram maintain approximately the listed grooving pressures for size
and wall thickness of pipe to efficiently form the groove.

4. Maintain grooving
force until the Knurled
Stop (groove diameter
stop) comes into full,
firm contact with the
top of the groover
base head. Allow the
pipe to rotate 1 to 2
revolutions assuring
completion of the
groove.
Release the foot switch to allow the pipe to stop rotation.
5. Open the hydraulic
hand pump release
valve by turning
counterclockwise.
Remove the pipe from
the Groover.
Check the groove
diameter. If required,
adjust the groove
diameter stop to
assure grooves to be
within Gruvlok groove
specification limits.
(Grooving Specifications are shown in Section X of these
instructions.)
Note: Adjustment of the Knurled Stop (groove diameter stop) will
produce the below listed groove diameter changes.

**Knurled Stop Rotation:
Clockwise rotation – Increase groove diameter
Counterclockwise rotation – Decrease groove diameter
6. After adjustment of the Knurled Stop, if the groove diameter is
large (i.e. shallow groove depth), place the pipe end back into the
Groover and complete the same groove to the new diameter stop
setting. If the groove diameter is small (i.e. deep groove depth),
put an unfinished end into the Groover and complete the groove.
Recheck the groove diameter for conformance to grooving
specifications.
