3. Continue to advance the ram and bend the pipe.
As the pipe is bent, the ends will move. Stay clear
of the moving pipe. Monitor the angle indicators
(Figure 15). The average of the angles measured by
each angle indicator equals the approximate total
angle bent.

Watch the ram as it extends. If you can see a small
groove in the ram (Figure 16), stop advancing the
ram to prevent hydraulic leaks and ram damage.
4. For certain sizes of pipe (2
must be used to form a 90 degree bend. When the
groove in the ram (Figure 16) is visible, stop ad-
vancing the ram. Make sure that the pipe is prop-
erly supported to prevent it from moving or falling.
Turn the release knob to the retract position, and
retract the ram far enough to allow the extension
to be inserted between the end of the ram and the
former. Insert the extension and carefully advance
