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.
1. The machine must only be commissioned in full knowledge of the
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,
except as specified in regulations DIN VDE 0105.
10. Conversion or changes to the machine must be authorized by us
and made only in adherence to all safety regulations.
11. For repairs, only replacement parts approved by us must be used.
12. Commissioning of the sewing head is prohibited until such time as
the entire sewing unit is found to comply with EC directives.
13. The line cord should be equipped with a country-specific mains
plug. This work must be carried out by appropriately trained
technicians (see paragraph 8).
It is absolutely necessary to respect the safety

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 f or 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 tur n 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 t he 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.
