J
Insert adapter nipple (only d26 to d40).
f
J
Place required bending gauge onto the adapter nipple.
g
J
Insert mandrel into the bending roller.
J
Insert bending rollers into the required hole.
h
J
Connect hydraulic coupling to hydraulic nipple of the bending tool.

J
Connect control cable of the bending tool to the connector socket of the hydraulic
unit.
Performing bending
k
J
Specify bending angle.
J
Adjust the slider to the corresponding dimensions and angle and fasten with the
positioning screw.
l
J
Mark the middle of the curve on the pipe.
Table [TV.26]
J
Lay the pipe into the bending gauge. When doing so, observe the middle of the curve.

J
Press and hold down start button on the bending tool
The bending instrument performs the bending procedure.
A
The bending instrument finishes the bending procedure automatically once the
required bending angle has been reached.
