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

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.
It is absolutely necessary to respect
the safety instructions marked by these signs.
Danger of bodily injuries !
Please note also the general safety instructions.
