Preparation for start-up
1. Working position (See figure B.1)
The position shown in the sketch would be ideal for
comfort and safety during the entire bending process.
2. Working area (See figure B.2)
Before start, the bending area should be clear
from any element that may interfere in the bending
process.
3. Use of extension cords
The extension cable should as thick and short as
possible. It should handle more than 15 Amp., and
never be more than 30 m. in length.
4. Check the state of the on/off switch
Make sure that the on/off switch unlocks
automatically when not pressed.
5. Use of tripod (optional) (See figure B.3)
The sketch shows assembly and coupling of tripod to
bending machine.
6. Device for series bending (See figure B.4)
The unit provides a device for setting the bending
angle automatically from 0º to 180º. To operate,
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.
Important: It is not advisable to use this option
on pipes larger than Ø 22 x 1,2 mm.
7. Keepaway from moving parts
Make sure that your hands are not in contact with
moving parts of the machine during the bending
process
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
® 3000 is set in the start
position by starting the motor with the 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.
Before carrying out any inspection of the
ROBEND
® 3000, check that the plug is
disconnected from the power supply.
Important: should any form of service/repair
other than the basic points detailed below be
required, please contact your nearest technical
service centre.
A.The bending former stops rotation during
bending, while the motor is still running.
The direction lever is not in the right position.
There is a transmission problem - contact your
technical service centre.
B. Bends are not round/circular
Bending former and/or shoe are not suited to the tube
size. Bending former and/or shoe are worn out.
Tube quality is suspect.
C. The ROBEND
® 3000 does not start
Check the wiring in the plug.
Carbon brushes may be worn out and need replacing.
D. Pre-set trigger does not function
Screws are not tightened properly.
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 . The
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).
The ROBEND
® 3000 is equipped with a device that
allows you to preset the bending angle between 0
to 180 degrees which is ideal for repeat bends. See
“preparation for start up” chapter.
5. Once the been has bend produced and the power
switch has been released, shift the direction lever back
into the reverse position . Now, briefly push the
power switch to loosen the hold on the tube. 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.
6. In order to make the ROBEND
® 3000 ready for
the next bending operation, start the motor with
the direction lever in the reverse position until it
triggers off and moves into the neutral position.
Care and maintenace
Before carrying out any job on the machine,
disconnect the plug from the mains outlet.
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 any
anomaly, replace immediately with a new one.
3. Brushes
Check frequently for brush wear and perfect contact
with rotor. Change brushes when their lengths is
1/3 of original length. Use original ROTHENBERGER
brushes.
4. Motor and rotor
The carbon dust accumulated in the motor and brush
housing should be removed every 100 hours. The
motor’s rotor should be permanently clean with a
uniform surface (light bronze colour).
5. Gear box
Change grease every 500 operating hours. After
dismounting the machine, oil all mechanisms
to eliminate old grease. Remove parts with dry
compressed air and apply new grease with clean
hands. Do not use any dissolvents. Approximately 300
grs. of grease is needed for a correct lubrication. An
excessive amount of grease is not recommended as it
can increase the temperature of the machine. Grease
type: LGMT2 by SKF or similar. We recommend that
this operation be carried out by an authorized after-
sales service.
6. Dismounting the gear box
Before dismounting the cover of the gear box, never
introduce sharp objects such as tips, screwdrives, etc.
between the body and cover’s connecting faces. The
correct procedure is to tap the front of the octagon
gently with a plastic hammer.
7. Machine maintenance and repair should be
done by a specialist
All repairs should be carried out by a specialist and
only original parts should be used.
