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 advanc-
ing the ram. Make sure that the pipe is properly sup-
ported 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 the ram. Do not
place your fingers, hands or other body parts in a
position that would allow them to be trapped or
crushed.
