Pipe Set-Up

1. Pipe or tubing longer than the specified maximum
lengths listed in Charts A & B must be supported with
two (2) pipe stands. If only one stand is used, the pipe
should be centered on the stand so that the pipe's
center of gravity is over the center of the stand.
Failure to use two stands may result in
WARNING
unit tipping or the pipe falling. Make sure stands and pipe
are stable.
2. Raise upper groove roll housing by placing pump
release lever in RETURN position.
3. Square pipe and pipe support to roll groover making
sure pipe is flush against drive roll flange. (Figure 9)

4. Verify that the pipe is level or sloped slightly upward
away from the operator.
NOTE! If the machine cannot be leveled, make sure
that the slope of the pipe and the machine are
the same.
If pipe is grooved with free end of pipe (end of
CAUTION
pipe which is not in tool) too much higher than the end
being grooved, pipe may not track and pipe end flare may
result. Pipe exceeding fitting manufacturer's recom-
mended flare specifications may prevent assembly of
couplings pad-to-pad, allowing possible pipe separation,
and result in property damage. Also, joint leakage may
result due to excessive gasket distortion/damage.
5. Check that the pipe is square with the drive shaft or
tilted upward 1 / ° from the operator.

CAUTION "Tracking Angle" will affect pipe end flare
(Figure 10). When pipe end flare is excessive, left-to-right
tracking angle must be kept to a minimum. It may be
necessary to use an angle less than 1 / º.
