ASSEMBLING
1.a. 1 1 / 4 ", 2" and 3" machines.
Place the bending frame with its supports on
the floor and slip the ring over the front of the
pump cylinder.
Place the U-bracket through the holes in the
ring block of the bending frame.
The pump cylinder and pipe bending frame
are now fixed in the correct position.
1.b. 4" machine.
–
Place the base beam on the floor.
–
Place the lower wing on the base
beam.
–
Place the bending-pump on the base
beam, hook the lower wing into the
pump and secure the pump at the rear
with two M10 bolts.
–
Place the corner-supports and where
applicable the bending-former that you
will be using, on the lower wing.
–
Place the upper wing on the corner-
supports and hook into the pump
–
Insert the fixing-pins through the wings
and the corner-supports.
2.
Mount a bending former according to
the diameter of the pipe to be bent, on the
ram top. The corner supports must be placed
between, or on the bending frame. They are
fastened by means of the fixing-pins.
The holes in the frame allow the corner
supports to be adjusted to the desired
outside diameters.
These holes are marked accordingly.
Ensure that the fixing pins for corner sup-
ports are properly fitted through both wings
or through the bending frame to prevent
damage.
BENDING
1.
The filling cap is pierced for air release.
Whenever the bending machine is transpor-
ted this filling cap must be tightly closed, but
released a little when in use.
2.
Before bending, the pipe should be
slightly greased. The pipe is then slipped
between the corner supports and bending
former. The relief spindle must be locked
tightly. By moving the handle up and down
the pump is put into operation. The ram
moves out and the pipe is bent. The bending
operation should be continued until the
desired curve is reached but not further than
the bending forner curve.
It should be remembered that the pipe will
spring back a little according to the quality
of the pipe. This must be established by
experience.

3.
As soon as the pipe has reached its
required shape, loosen the relief spindle and
the ram withdraws automatically.
Disconnect one of the corner supports and
the pipe can be removed.
The models equipped with an open frame
have the advantage that the bent tube can be
removed easier, especially long pieces of
tubes with several bends, thus saving a lot of
time.
4.
If a bend has been bent too far this can
be corrected by means of the straightener.
The ram must be reserved and the tube
turned over against the corner supports.
The straightener is placed on the ram top
and the bend can now be pushed back to its
desired shape. On the 1
a bend of 90o cannot normally be corrected.
This also applies to the 3" machine for 2
and 3", for the 4" machine for 3" and 4"
pipes.
5.
For 3" and 4" model only.
When bending 2

", 3" and 4" pipes an

extension piston should be applied to the ram
when the tube has been bent past 75 o .
The stroke of ram is not enough to bent a
90 o bend in one time.

The electro-hydraulic pipe bending machines
are equipped whith a single phase 115V,
230V, AC or 400V 3 phase motor.
The motor has a special safety switch. Once
the motor is running the movement or the
ram is controlled by means of a relief spindle
which can be either opened or closed.
The motor does not have to be switched off.
The machine also features a pressure safety
valve. This is factory set so that heavy wall
pipe (steampipe) can be bent without any
problem. The pressure safety valve is situ-
ated in the pumphouse and can only be set
by means of a manometer.

the size of the pipe to be bent, placed on the
ram. Next, the plates (spare frames) with
3 rolls (diabolos) are adjusted between or on
the frame. The fixing-pins for corner supports
must be put in the holes 1 1 / 4 " through the
center lock; the removable diabolo must be
removed and the pipe to be bent run through.
The pipe must now touch the center diabolo
with one side and the 180 o bending form
with the other side.
Bending can now be started.

spindle. Adjust the removable diabolos and

see Bending.
MAINTENANCE
The bender is delivered with a filled oil con-
tainer. However, the oil level must be checked
regularly as otherwise the stroke or the ram
will become too short.
Oil must always be level with the bottom of
the filling cap. If oil needs to be added, use
only hydraulic oil.
CAUTION

according to the size of the pipe to be bent.
If not placed properly, the ram instead of the
pipe may be bent and the machine badly
damaged.
