Foreword
This instruction manual is intended to help the user to become familiar
with the machine and take advantage of its application possibilities in
accordance with the recommendations.
The instruction manual contains important information on how to
operate the machine securely, properly and economically. Observation
of the instructions eliminates danger, reduces costs for repair and
down-times, and increases the reliability and life of the machine.
The instruction manual is intended to complement existing national
accident prevention and environment protection regulations.
The instruction manual must always be available at the machine/sewing
unit.
The instruction manual must be read and applied by any person that is
authorized to work on the machine/sewing unit. This means:
–Operation, including equipping, troubleshooting during the work
cycle, removing of fabric waste,
–Service (maintenance, inspection, repair) and/or
–Transport.
The user also has to assure that only authorized personnel work on the
machine.
The user is obliged to check the machine at least once per shift for
apparent damages and to immediatly report any changes (including the
performance in service), which impair the safety.
The user company must ensure that the machine is only operated in
perfect working order.
Never remove or disable any safety devices.
If safety devices need to be removed for equipping, repairing or
maintaining, the safety devices must be remounted directly after
completion of the maintenance and repair work.
Unauthorized modification of the machine rules out liability of the
manufacturer for damage resulting from this.
Observe all safety and danger recommendations on the machine/unit!
The yellow-and-black striped surfaces designate permanend danger
areas, eg danger of squashing, cutting, shearing or collision.
Besides the recommendations in this instruction manual also observe
the general safety and accident prevention regulations!

General safety instructions
The non-observance of the following safety instructions can cause
bodily injuries or damages to the machine.

instruction book and operated by persons with appropriate training.
2. Before putting into service also read the safety rules and
instructions of the motor supplier.
3. The machine must be used only for the purpose intended. Use of
the machine without the safety devices is not permitted. Observe all
the relevant safety regulations.
4. When gauge parts are exchanged (e.g. needle, presser foot, needle
plate, feed dog and bobbin) when threading, when the workplace is
left, and during service work, the machine must be disconnected
from the mains by switching off the master switch or disconnecting
the mains plug.
5. Daily servicing work must be carried out only by appropriately
trained persons.
6. Repairs, conversion and special maintenance work must only be
carried out by technicians or persons with appropriate training.
7. For service or repair work on pneumatic systems, disconnect the
machine from the compressed air supply system (max. 7-10 bar).
Before disconnecting, reduce the pressure of the maintenance unit.
Exceptions to this are only adjustments and functions checks made
by appropriately trained technicians.
8. Work on the electrical equipment must be carried out only by
electricians or appropriately trained persons.
9. Work on parts and systems under electric current is not permitted,

6. Pneumatic connection
For the operation of pneumatic components, the sewing unit has to
be supplied with anhydrous compressed air.
ATTENTION!
For a trouble-free function of the pneumatic control procedures, the
compressed air supply must operate as follows:
Even at the moment of the highest air consumption, the minimum
operating pressure must not drop below 6bar.
In case of important drop of the air pressure:
–Increase the compressor output.
–Increase the diameter of the compressed air hose.
Connecting the maintenance unit for compressed air
–Connect the unit to the compressed-air supply with the
connection hose 3 (Order no. 0797 003031) and connector
R1/4".
Adjusting the operating pressure
–The operating pressure is 6 bar.
It can be read off at the manometer 2.
–To adjust the operating pressure raise and turn handle 1.
–Turn clockwise = increase pressure
–Turn counter-clockwise = reduce pressure
ATTENTION!
No oil-bearing compressed air must be fed from the compressed air
line.
The cleaned compressed air after the filter is used as blowing air for
cleaning machine parts and for blowing workpieces out.
Oil particles contained in the blowing air lead to malfunctions and
stains on the workpieces.

7. Oil lubrication
Caution: Risk of injury!
Oil can cause skin rashes.
Avoid longer skin contact.
After contact wash yourself thoroughly.
ATTENTION!
The handling and disposal of mineral oils is subject to legal
regulations.
Deliver used oil to an authorized collecting station.
Protect your environment.
Be careful not to spill any oil.
For filling up the oil reservoirs use only DA 10 lubricating oil or an
equivalent oil with the following specifications:
–Viscosity at 40° C : 10 mm2/s
–Ignition point : 150° C
DA 10 is available from DÜRKOPP ADLER AG retail outlets under the
following part numbers:
250 ml container: 9047 000011
1-litre container: 9047 000012
2-litre container: 9047 000013
5-litre container: 9047 000014
Oil reservoir for the lubrication of the machine head
–Fill oil reservoir 1 with oil through the drill-hole 2 in the inspection
glass.
The oil level must be between the “Min” and “Max” markings.

feeding process are initiated one after the other and the sewing
process is started.
ATTENTION!
Please make sure that material is positioned under the transport
clamps at the sewing start.
Moving the transport carriage without material will damage the
coating of the transport clamps.
–For the selection of the sewing program and for further settings of
the control unit see chapter 7 of the operating instructions.
