1007 & 3007 ROLL GROOVER
GROOVING THE PIPE OR TUBE - COPPER TUBE: CTS COPPPER SYSTEM
MODEL 3007 ONLY – Extremely Important
Check to see that the Ridgid* 300 drive directional switch is set to
"reverse" position (clockwise rotation of the tube looking at the front
of Groover.) Tube must be square on ends. Burrs must be removed. Any
tube manufacturing seam, on inside or outside of tube, must be
removed.
Using the pressure gauge mounted on the hydraulic ram maintain
approximately the listed grooving pressures for size and type of tube
listed below to efficiently form the groove.

Recheck for correct tube

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 100 psi.
Start the drive motor by
2
depressing the foot switch to
rotate the tube. Assure that
the tube is tracking firmly
against the back of the
bottom roll.
With the tube rotating,

increase grooving force by
slowly pumping the
hydraulic pump handle to
raise pump pressure.
Do not pump too fast.

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
After adjustment of the Knurled Stop, if the groove diameter is large
6
(i.e. shallow groove depth), place the tube end back into the Groover
PSI
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.
*"RIDGID" is a registered trade mark of Emerson Electric Company.
Maintain grooving force until
4
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.
Open the hydraulic hand
5
pump release valve by turning
counterclockwise. Remove
the tube from the Groover.
Check the groove diameter.
If required, adjust the groove
diameter stop to assure
grooves to be within Gruvlok
