3.2 Transport
The unit is equipped with four castors for easy mobility within your
premises.
Caution!
Prior to the commissioning of the sewing unit, slide the rubber caps 1
over the feet of the frame.
For the operation of the sewing machine, the castors 2 must be lifted
so that the unit is standing on its feet.
–Lower the castors to transport the unit within your premises by
turing the set screws 3 anticlockwise.
For transport, ensure that the frame feet 1 are sufficiently lifted
from the ground.
–After transport, lower the sewing machine until it stands firmly on
its feet
by turning the set screws 3 in clockwise direction.

3.3 Adjustment of working height
The working table can be adjusted continuously to a height between
820 mm and 1080 mm. Upon delivery, the sewing unit is set to the
lowest working height.
To adjust the working height, proceed as follows:
–Loosen locking screws 1, 2, 3 and 4 at the struts of the frame.
–Adjust working height to desired level by using suitable tools.
To prevent jamming, simultaneously lift table at both sides.
–Tighten locking screws 1, 2, 3 and 4 at the struts

3.4 Installation of yarn stand
Ensure that the yarn stand 4 and the unwinding bracket 3 are
positioned at the maximum possible distance from each other and
vertically aligned.
–Insert yarn stand 2 in hole 1 and secure with nuts and washers.
–Mount and align yarn stand 3 and unwinding bracket 4 as shown in
the above figure.

3.5 Installation of suction unit
The suction unit consists of a waste bin 1, the vacuum valve 2, the
suction hose 3 and the vacuum hose 4. The device ensures that
cut-offs are constantly removed from the edge cutter.
The suction unit is equipped with adapters for connection to the
vacuum unit in the premises. If there is no such unit, install the
centrifugal blower 10, which is available as an optional device.
–Place waste bin 1 behind the sewing unit.
–Push suction hose 3 onto the suction connectors below the table
top.
–Connect the other end of the suction hose 5 to the socket 6 of the
waste bin.
–Insert vacuum hose 4 into the socket 7 and connect the other end
of the hose to the internal vacuum unit or a centrifugal blower.
–Connect control hose 9 to pneumatic cylinder 8.

3.6 Power connection
CAUTION!
Work at electrical components must be carried out
by electricians or other suitably trained staff.
Prior to such work, always disconnect unit from the power supply.
Always comply with the instructions given by the manufacturer of the
step motors in the enclosed operating manual.
3.6.1 Checking of power supply voltage
CAUTION!
The nominal voltage indicated at the type plate and the power supply
voltage must correspond!
Type plate at Efka control unit.
3.6.2 Connection to power supply
–Plug in power plug.
3.6.3 Direction of motor rotation
–The sewing machine is equipped with state-of-the art step motors.
It is therefore not necessary to test the motors as regards their
direction of rotation, as it is automatically set by the control system.

3.7 Pneumatic connection
3.7.1 Connection to compressed air maintenance unit
For the operation of the pneumatic devices, the sewing machine must
be supplied with dry compressed air.
CAUTION!
To cater for correct pneumatic control processes, the compressed air
supply must be set up as follows:
“At the moment of max. air consumption, the minimum operating
pressure may not be below 5 bar.”
The supplied compressed air may not contain any lubricants. After the
air has passed the filters, cleaned compressed air is brought to the
machine for the blowing out of sewing pieces.
If the air were to contain lubricants, they would contaminate the sewing
part and result in disruptions.
–Connect compressed air maintenance unit 2 to the maintenance
unit by means of the connecting hose (Ø = 9 mm) and the G1/4"
hose coupling.
–
Pneumatic connection set
The pneumatic connection set is available as item no. 0797 003031
and is a pneumatic adapter set for frames with compressed air
maintenance units.
It contains the following components:
- connecting hose, 5 m long, (Ø=9mm)
- hose socket and connectors
- coupling socket and plug

3.7.2 Adjustment of operating pressure
The operating pressure of the sewing machine is 6 bar.
This pressure is displayed on manometer 2.
–To adjust the operating pressure, pull handle 1 up and turn.
Increase pressure = turn handle 1 clockwise
Reduce pressure = turn handle 1 anticlockwise

3.8 Lubrication
Caution risk of injury!
Oil might cause allergic reactions on skin.
Avoid any contact with skin.
If skin has been in contact with oil, wash thoroughly.
CAUTION!
The handling and disposal of mineral oils are governed by statutory
regulations.
Dispose of the oil through the proper channels.
Protect the environment and ensure
that no oil is spilt.
To refill the oil tank, use only ESSO-SP-NK 10 lubricant or a similar
product of the following specification:
–Viscosity at 40° C: 10 mm²/s
–Ignition point: 150° C
ESSO SP-NK 10 is available from all
DÜRKOPP ADLER AG agencies with the following part number:
2 litre container: 9047 000013
5 litre container: 9047 000014
Oil tank for lubrication of the sewing machine head
The sewing machine head is equipped with a central oil wick. All
bearings are lubricated from oil tank 1.
–Fill oil tank 1 through the opening in the glass panel to the “MAX”
level mark.
