8. Restrict access or set up guards or barriers to create
a minimum 3' (1m) clearance around the equipment
and pipe. This helps prevent non-operators from con-
tacting the equipment or pipe and reduces the risk of
tipping or entanglement.
9. With dry hands, plug the machine into a properly
grounded outlet.
Setting/Adjusting Groove Diameter
NOTICE Due to differing pipe characteristics, a test
groove should always be performed before the first groove
of the day or when changing pipe size, schedule, mate-
rial, or lot to reduce the risk of out of tolerance grooves.
Groove diameter must be measured to confirm proper
size.
1. Confirm that equipment is properly set up and pipe is
properly prepared and loaded. Improper set up and
preparation can affect accuracy of groove diameter
settings.
2. Groove roll should be lightly gripping the pipe. If
needed, advance the groove roll to just touch and
lightly grip the pipe – it should not be making an in-
dentation in the pipe, do not apply excessive pressure.
3. Rotate the depth adjustment nut until it stops against
main housing.
4. Back the depth adjustment nut off one turn (Figure
13).

Stabilizer Operation
The stabilizer is used to apply slight force to 2
pipe to improve tracking. It is especially useful for short
pieces of pipe, but can be used on all lengths of pipe.
The stabilizer also reduces the swaying of longer, larger
diameter pipe.
1. Properly set up equipment and load pipe.
2. Set groove diameter.
3. Rotate the stabilizer crank handle to bring the roller

• To increase groove diameter (shallower groove), turn
the depth adjustment nut clockwise.
• To decrease groove diameter (deeper groove), turn
the depth adjustment nut counterclockwise.

can be adjusted and the groove made smaller. If the
groove is too small, another groove will need to be
