4.3. Description of the light diode display
This tool is equipped with a special circuit board incorporating several important features to
inform the user about the current status of the unit. The diode (Pos.-No. 6) signals in the
following cases:

5. Remarks in respect of the determined use
5.1. Operation of the units
First the interchangeable bending shoe (Pos.-No. 10) must be mounted on the piston
depending on the outside diameter of the tube and fastened by the wing nut (Pos.-No. 3 &
Picture 2 Pos. A). The arrester (Pos.-No. 9) can be universally used for all tube diameters.
The 360° rotatable bending head (Pos.-No. 4) will be put into position and the tube will be
placed into the arrester.
The bending procedure is initiated by actuating the trigger (Pos.-No.1 & Picture 2 Pos. B).
The moveable bending shoe (Pos.-No. 10) approaches the tube (see picture 3). After contact
the double piston pump switches from the fast advance speed to the slow working speed.
The tube is now bent to the desired bending angle (see picture 4). The bending cycle is
terminated when the desired bending angle is achieved and the tube maintains this angle
after release.
After pressing the retract button (Pos.-No. 2) the bending shoe return into their initial
position (see Picture 2 Pos. C). Afterwards a second bending process can be initiated.
Attention
The bending process can be interrupted at any moment by releasing the trigger
(Pos.-No. 1).

Remarks:
- Does the diode signal periodically at the end of a working cycle for approx. 20 sec the unit must be returned to an
authorised Service Center for Service as soon as possible.
- In case of an error the light diode display also signals periodically at the end of a working cycle. The signal
indicates in this case the circuit opening by the electronic fuse. A possible reason for that is that a cycle was
performed with an incorrectly low battery. If the signal occurs even after changing the battery there must be a
different error or a service is due. In these cases the tool must be returned to the manufacturer or an authorised
service center.

The unit switches off when it gets too hot. It switches on automatically after the unit cooled off.
