place.
It is recommended that the stabilizer be used
CAUTION
for all lengths of pipe. Stabilizer will help prevent pipe walk-
ing off the groove rolls. It will also prevent swaying on the
longer pipe lengths.
Roll Guards
The guards covering the grooving rolls and the stabiliz-
er wheel will automatically close and open as the upper
groove roll is moved in or out of the grooving position.
The guard on the operator side will also adjust with the
stabilizer.
WARNING
Do not operate the Roll Groover with the
guards removed. Make sure the guards are operating
properly and are not damaged. Repair damaged guards
before using the groover. Exposure to moving grooving
rolls or stabilizer wheel may result in fingers being
crushed.
1. Before placing the pipe into the groove rolls, check
that the upper grooving roll is fully retracted by rotat-
ing the pump release lever counter-clockwise. The
guards should be in the open position as shown in
(Figure 13) .
Figure 13 – Guards in Open Position
2. With pressure applied to the hydraulic cylinder and the
upper roll in the grooving position, the guards should
be in the closed or operating position as shown in
Figure 14 . the guard on the operator side will move
in and out with the adjustment of the stabilizer.

Adjusting Roll Groove Depth
NOTE! Due to differing pipe characteristics, a test groove
should always be performed when setting up or
changing pipe sizes. The depth adjusting nut
must be reset for each diameter of pipe/tube.
Using the Groove Depth Setting Gauge
The groove depth gauge is designed to make an initial
estimate of the depth required to achieve the required
groove diameter.
1. Insert the pipe into the roll groover and actuate the
hand pump until the cylinder builds up to approxi-
mately 500 psi.
2. Put the correct section of the gauge under the adjust-
ing nut. (Figure 15)
