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

4 Electrical Connection
ATTENTION !
All jobs on the electrical equipment of the sewing unit may be
performed only by qualified electricians or appropriately trained
personnel.
In the process, make sure that the mains plug is pulled out.
4.1 Checking the nominal voltage
ATTENTION !

5 Pneumatic Connection
For the operation of the pneumatic components, the sewing unit must
be supplied with anhydrous compressed air.
ATTENTION !
For faultless functioning of the pneumatic control operations, the
compressed air network must be designed as follows:
Make sure that a minimum operating pressure of 6baris not
exceeded even when air c onsumption is at its highest.
In the event of excessive compressed air drop:
–
–
Increase the compressor performance.
Increase the diameter of the compressed air supply line.
32 1
Connect the compressed air maintenance unit
–
Connect the connecting hose 3 to the compressed air network.
Adjust the operating pressure
–
The operating pressure is 6 bar.
It can be read out on the manometer 1.
–
Lift up and tur n the turning handle 2 for adjusting the operating
pressure.
- Turning in clockwise direction = Increase pressure
- Turning in anti-clockwise direction = Reduce pressure
ATTENTION!
The compressed air network may not be used to supply oiled
compressed air.
Behind the filter, purified compressed air is extracted as blow air for
the cleaning of machine parts and for blowing out the sewing parts.
Oil particles that are entrained with the blow air lead to functional
faults and contamination of the sewing parts.
