Figure 9 – Pump Release Lever Position
Loading Pipe in Roll Groover
1. Confirm that the switch is in the OFF position.
2. Fully retract the groove roll.
3. Appropriate pipe stands must be available to support
the pipe. Adjust the height of the pipe stands so that
the pipe will be level and the top inner diameter of the
pipe will sit on top of the drive roll (See Figure 10).
Place the pipe stands in directly front of the roll
groover. Pipe stand placement depends on the pipe
length.
For shorter pipe (see Chart A) the pipe is supported
by the drive shaft and at least one stand. In this case,
the stand should be placed slightly more than half the
length of the pipe from the roll groover.

Chart A – Minimum/maximum pipe length to be grooved
with one stand (in inches)
For longer pipes at least two stands should be used, with
the two stands placed approximately ¼ of the pipe length
from the ends of pipe. Failure to properly support the pipe
may allow the pipe or the pipe and machine to tip and fall.
Always use a pipe stand – it helps to align the pipe and
maintain proper tracking.

Figure 10 – Placing Pipe Over Drive shaft, Flush to Drive
Shaft Flange (Stabilizer Removed for Clarity)
4. Place the pipe on the stand(s) with the end of the pipe
flush to the drive shaft flange and the inside of the
pipe contacting the top of the drive shaft (Figure 10).
Make sure the pipe is stable and secure.

5. Advance the groove roll until it touches and lightly
grips the pipe (Do not drive the groove roll into the
pipe).
6. Confirm the pipe positioning. If the pipe is not properly
positioned, the groove may not track properly.
• The pipe end should be flush against the drive shaft
flange.
• The centerline of the pipe and the centerline of the
drive shaft should be parallel. This can be checked
with a level on top of the hydraulic cylinder and on
the pipe. See Figure 11.
• The roll groover / machine should be sitting firmly on
the ground. If the machine is lifting off the ground at
all, the pipe stand(s) are set improperly and should
be adjusted.
7 . Slightly offset the pipe and pipe stands approximately
½ degree (about 1" over at 10 feet from the roll
groover) towards the operator. Proper alignment of the
pipe and roll groover helps to ensure proper tracking of
the pipe while grooving (See Figure 12). This is proper
offset for grooving and works with the stabilizer.
