mark at the center for alignment. Properly support the
pipe to prevent tipping of the pipe and the bender
throughout use.
6. Apply grease to the side of the corner support that
contacts the pipe. Place the supports at the appro-
priate holes as marked on the bending frame. The
corner supports must be located in the correct, sym-
metrical holes or the bender can be damaged during
use.
Figure 10 – Loading the Pipe
7. Close the bending frame and fully insert the corner
support pins through both wings of the bending frame.
Align the corner supports so that the zero marks on
the angle indicators line up with the mark on the
upper wing (See Figure 12) .
Open wing benders do not have angle indicators.
Make sure the pins are fully inserted into the lower
wing.
8. Confirm that the bender and pipe are stable.
Advancing/Retracting The Ram
Turn the release knob clockwise on the hydraulic pump to
the closed (advance ram) position (See Figure 11.) To
retract ram, turn release knob counter clockwise to retract
position. An internal spring will retract the ram.
Manual Pump
Move the pump handle up and down to advance the ram.
Do not use handle extensions. This can damage the han-
dle or slip during use and cause injury.

Electric Pump
Move the ON/OFF switch to the ON ( ) position. Press the
RUN switch to ADVANCE the ram. Place ON/OFF switch
in OFF ( ) position when not in use or retracting the ram.
Bending The Pipe
1. Stand next to the cylinder on the same side as the
Release knob. Do not reach over the machine to
operate. Advance the ram. When the bending for-
mer touches the pipe, slowly and carefully advance the
ram while aligning the bend location with the former.
Continue advancing the ram until the pipe is just
against the corner supports. Do not place your fingers,
hands or other body parts in a position that would
allow them to be trapped or crushed.
2. Confirm that the corner supports are in the correct
position (as marked on the frame) for the pipe to be
bent and the pins are fully inserted in the frame (See
Figure 12) . If not, the bender can be damaged during
use. Make sure that the ends of the pipe extend past
the corner supports enough to prevent the pipe from
slipping off during bending. See Chart 1.
