7.1 Set up
Mount the machine firmly on the ground at a suitable
location.
Note the following:
• Make sure you have enough space around the ma-
chine (see Fig. 3).
• Make sure that the bending machine is firmly screwed
to the floor.
Fig. 3: Set up example
8 Work and operation
Information about the use of the machine
• Do not bend other steels than standard structural steel.
(8 x 50 mm and round steel up to Ø16 mm, rectangular
steel up to a size of 14 x 14 mm and heating pipes up to
a size of G3 / 4˝!
• Do not bend materials thicker than 6 mm around the
center pin. Always use the Ø24 mm rollers to prevent the
bolt from bending.
• Do not use additional lever extension.
• Do not use the right-angle bending accessory to bend
wooden blocks.
• When using the right angle bend accessory, bend only
standard steel up to 6 x 50 mm or 7 x 30 mm.
• Keep the work area around the machine clean to avoid
unnecessary accidents.
• Preventing the bending roller from dropping suddenly
could cause serious injury.
• When shearing, edging and bending, you can mount a
rip fence. To do this, screw the guide pins of the rip fence
to the frame.
8.1 Application of the eccentric counter-holder
This counterholder in the bending arm ensures that the
material is firmly clamped during the bending process.
Fig. 4: Counter-holder
The eccentric anvil offers four positions. Always use the
proper position to bring the anvil as close as possible to
the center pin or roller, but make sure that a small gap is
left for the material.
To reach two of the four positions, the anvil must rotate
from side to side. If the hole is to the left of the center, the
backstop will slip and thus the material will. If you are
using a large bending roller, insert the counterholder and
stop into the corresponding hole so that the material is
firmly attached. Place the anvil as close to the central
bolt or to the bending roller as possible and turn the anvil
into one of the four positions. You can adjust the stop on
the support plate by one hole forward or backward to
achieve the required clearance.
Too large a distance between the central bolt or the ben-
ding roller and the stop causes the slipping of the mate-
rial and thus an inaccurate bending radius.
If a very accurate bend radius is desired, it is prudent to
secure the material with a retainer clip against the anvil
to prevent the material from slipping.

Application of right-angle bending accessory
Fig. 11: Application of the bending accessory
If you want to bend a right angle, mark the location of the
sheet with chalk. When inserting the material into the
bending machine, make sure that the marked area is still
partially visible. The bending edge of the right-angle ben-
ding accessory covers the other side of the marked loca-
tion.
If two right angles are to be bent on the same flat mate-
rial (eg 5 x 25 mm), the marked points must be separa-
ted by 3 mm more than the required inner dimension. If
the material thickness is different, the corresponding
bending allowances must be taken into account
If very precise work is needed, first bend a specimen be-
fore bending a large amount. So you can find out if you
need to move the spot or if you need to lengthen or shor-
ten the material.
This instruction manual specifies the bending measure,
but if you are unsure about the dimensions, it is better to
use a narrower material than the required thick material,
which would be more expensive. If you are sure about
the bending and bending degree, make a note of it for
further use.
Fig. 12: Application of the bending accessory
The adjustable stop is used for equal curvatures. Make
sure that the screw is tight and that the stopper is tight.

This image shows the exact position of the chalk mark against
the bending edge of the right-angle bending accessory.
8.2 The production of U-shaped tabs

Fig. 17: Holes in the bending arm
8.3 Production of handles
Round material
With the bending machine you can produce handles with
different shapes and sizes. Each of the three illustrated
handles has been bent by Ø 15 mm and a length of 230
mm steel. After bending the bends, drill a Ø 15 mm hole
in the tab. Then insert the handle into the tab and weld it
tight. Sand the rest off the tab to get a flat surface.
The correct position of the eccentric counter-holder is gi-
ven by the diameter of the material (see picture on the
right). After you have made the first bend, you must turn
the material 90 ° and bend the other end 90 °.
Fig. 18: Production of handles
Flat material
Chalk the workpiece as shown in the picture. The mar-
kings on the ends must be on one side of the material,
the inside on the other side.
The dimensions in the illustration can be replaced by
others. Depending on the user's idea of the universal
bending machine.
Fig. 19: Production of handles with flat material
1. Curvature
Insert a flat material up to the mark (1) and bend it by 90
°. Check the angle before proceeding. Attach the eccent-
ric counterhold so that the respective angles are 90 °.

NOTE!
When using a different diameter material for the hand-
le, the diameter of the hole in the tab must be identical
to the diameter of the handle.

Work and operation
8.5 The production of U-shaped tabs and
mounting brackets
Before you start making U-shaped tabs, try bending a
pattern first. Check all sizes and make the necessary
changes.
Fig. 32: Finishing U-shaped tabs
Always move the eccentric anvil so that it is as close to
the bolt or bender as possible to prevent the material
from slipping.
If you want to extend the U-shaped tab, you will first find
out how much material you need for it. Now you have to
add twice the amount.
Example: If you want to extend the tab by 25 mm, you
must add 50 mm over the total length. The distance from
the eccentric anvil to the material end will only increase
by 25 mm. The other 25 mm are for the other end. The
bending machine has bending rolls of different sizes.
This allows you to bend different U-shaped tabs. Always
use rollers on the center bolt when working with a mate-
rial thicker than 9 mm. Otherwise you could accidentally
bend the bolt. The material is stretched during the ben-
ding process. This stretch is different for each material.
For this reason, we recommend that you test the stretch
even if you use this manual.
Make a note of the diameters of the bending rolls and the
dimensional deviation of the elongation. So you can save
time in a repeated production.
Fig. 33: Correct arrangement
Example 1
For a 9 mm screw with a length of 310 mm, the distance
from the eccentric anvil to the stop is 2.15 mm.
Fig. 34: Example 1
Example 2
For a screw with a length of 310 mm and a thickness of
12 mm, the distance from the eccentric counter-holder to
the stop is 1.15 mm.

Example 3
For screws with a length of 315 mm and a thickness of
15 mm, the distance from the eccentric anvil is 6 mm.
Fig. 36: Example 3
The sizes given here are suitable for making 250 mm
long screws. However, you can always vary the length
by simply shortening or lengthening the length. You can
also change the length of the material after curvature by
reducing or extending the length of the eccentric anvil.
Make sure that a sufficient length of material leans
against the counterholder.
9 Special accessories
9.1 Bending segment for spirals
The bending segment is supplied as a separate acces-
sory and can bend a hot rolled material of 5 x 25 mm.
The edge of the segment bends the material in a spiral. If
you want to make several spirals of the same shape,
mark the top of the bend segment where the first spiral
stops. If you bend the other spirals up to this mark, the si-
zes of the spirals will all be the same.
Fig. 37: Bending segments for spirals
By bending large and small spirals, you must first insert
the fence and the bend segment into hole 2.
Fig. 38: Insert stop
If you would like to produce a large spiral after the first
phase of bending, remove the stop of the bending seg-
ment from hole 2 and insert them into hole 5 (at the very
end).
Fig. 39: Making a big spiral
Do not bend a large spiral when the fence and bend seg-
ment are in hole 5. You need to start with it when in hole
2, otherwise the spiral will not be formed properly.

Care, maintenance and repair
Turn the spiral around as long as the bending segment
allows it. Take out the stop and the segment and place
them in the hole for the second bend and finish the spiral.
9.2 Heating pipe bending roll set
For cold bending of heating pipes of size G3 / 8 ", G1 /
2", G3 / 4 ". For a curvature of a heating pipe, a heating
pipe bending roll set is required (larger and smaller rolls).
The large roll is used as the middle and the material is
bent with it. The procedure is similar to the normal ben-
ding rollers.
Fig. 41: Heating tube bending rolls set
9.3 Clamp
It is used for mounting the dismantled bending unit of the
UB 10. For this you need three screws. The clamping
plate must be firmly mounted to an anchored workbench.
Fig. 42: Clamp
9.4 Adjustable stop 10-200
It is a universal, adjustable stop to produce material of the
same length for a series of bends. Use a screw and a nut
to secure the fence in the second or third hole.
Then turn the stopper so that the curved material is per-
pendicular to the outer side of the stopper. Fix the stopper
so that the material is parallel to the underside of the stop-
per. The adjustable stop can be fixed from both sides.

10 Care, maintenance and repair
NOTE!
The pipe must not be bent more than 180 °, other-
wise it will jam in the bending roller.
