918 Roll Groover

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 12). 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 driveshaft
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 13.
• 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. Preferred Operation – Switch in REV Setting:
Slightly offset the pipe and pipe stands approximately
1/2 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 14). This is proper
offset for grooving with the machine in the REV switch
setting, and works with the stabilizer.
Alternate Operation – Switch in FOR Setting: If
using the machine in the FOR switch setting (such as
with a 535 Auto Chuck Machine not converted to grip
in both directions), then offset the pipe and pipe stands
approximately 1/2 degree (about 1" over at 10 feet from
the roll groover) away from the operator (see Figure
15). The pipe stabilizer cannot be used with the FOR
switch setting – it may cause pipe to spiral out of the
roll set.
