loosen the graduated scale surrounding the former shaft and align the desired angle with the inner
mark as shown. Once the angle has been selected, tighten the screws and proceed according to the
"start-up" chapter.
7. Keepaway from moving parts
Make sure that your hands are not in contact with moving parts of the machine during the bending
process.
5. Starting up
Before carrying out any operation with this unit, first read the general safety instructions and
preparation for start-up.
Important: For all bending applications, carefully follow the steps described beolw
1. Select the tube or pipe to be bent. Choose the relevant bending former and shoe suited to the
tubes size. Ensure that the ROBEND
direction lever in the reserve position until it triggers off and moves to the neutral position.
2. Place the bending former onto the centrepin. Lay the tube into the bending former and secure it into
the hook.
Important: Ensure that the tubes is fully inserted into the hook and has contact with the whole hook
surface. Secure the bending shoe with the fastening bolt into the appropriate housing.
3. Ensure you are at the correct starting position by checking the "0" mark on the bending former is lined
up with the centre of the bending shoe (see figure C.A).
4. To start bending, shift the direction lever to the working position and push the power switch
bending former will start to rotate. Maintain pressure on the switch until your chosen angle of bend
(marked on the bending former) (see figure C.B) lines up with the mark on the bending shoe, and then
release the switch (see figure C.C).
5. The ROBEND

to 180 degrees which is ideal for repeat bends. See "preparation for start up" chapter.
6. Once the been has bend produced and the power switch has been released, shift the direction lever
back into the reverse position
Once the tube has released you can remove the fastening bolt, then the bending shoe and finally
take the finished bend out of the bending former.

1. Cable and plug
Both the cable and plug should be in optimum condition. Check them at regular intervals.
2. ON switch
Check that the machine switch unblocks automatically when finger pressure is released. In case of
