11. Retract the groove roll and remove the pipe from the
roll groover.
12. Inspect and measure the groove.
Tracking Tips
A typical issue while roll grooving is the pipe "spiraling"
or "walking off" the drive shaft or not "tracking" properly.
For good tracking, it is important that all instructions be
followed. If, even after following all instructions, the pipe
will not properly track; there are other options to improve
tracking.
• Slightly increase the offset of the pipe (increase from
degree to 1 degree) See Figure 12.
• Tighten the stabilizer crank handle an additional ½ turn.
• The operator may need to apply slight force on the pipe
while grooving to maintain tracking. This is usually only
needed on shorter pieces of pipe when the stabilizer is
not used. To do this, the operator should wear a leather
glove in good condition and cup their hand around
the pipe as shown in Figure 16 to pull the pipe slightly
towards them. This may require that the stand be fixed
to the floor to prevent movement during grooving. To
reduce the risk of crushing and cutting injuries, keep
hand away from the groove roll and the ends of the
pipe, do not groove pipe shorter than recommended
and do not reach inside pipe or touch groove.

Inspect/Measure the Groove
1. Inspect the groove.
• Make sure that all features are present and fully
formed. See table II and Figure 17 .
• Measure the groove diameter and make sure it is
within specification.
• Check any other items required by the fitting manu-
facturer.
• Test the system in accordance with local codes and
normal practice.
If any problems are found, the groove cannot be
used. Proper groove diameter is important to ensure

connection performance. Out of specification grooves
could cause joint failure.
2. Measure the groove diameter. With a diameter tape
(see Optional Equipment Section). Snugly wrap
the diameter tape around the pipe in the groove.
Make sure that the tape sits flat in the bottom of the
groove and read the groove diameter (See Figure
17). Compare the measured groove diameter to the
required groove diameter as shown in Table II or III
or as specified by the groove fitting manufacturer.

Preparing Machine for Transport
1. Make sure that the ON/OFF switch is in the OFF po-
sition and the cord is unplugged from the outlet.
2. Clean the machine. Remove or secure all loose equip-
ment and material from the machine and stand prior
to moving to prevent falling or tipping.
3. Loosen the hydraulic pump wing nut, move the pump
to innermost position and tighten wing nut again. See
Figure 6.
4. Coil up the power cord and foot switch cord.
