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

6.4 Setting the machine-specific parameters
6.4.1 General notes
The functions of the sewing-drive control are determined by the
program and the parameter settings.
All parameter values for the relevant machine class and subclass are
pre-set by Efka prior to delivery of the sewing drives. For each class
and subclass some parameters at technician and manufacturer level
must be changed so that the control is perfectly adapted to the
machine. The parameters concerned are listed in the parameter sheet
(in the accessory pack).
The parameter 290 (selection of the machine class) has to be set to
the appropriated value in the “manufacturer level” (see parameter
sheet 9800 331101 PB30).
Please take the detailed description of the control from the attached
current operating instructions of the motor manufacturer (see also
www.efka.net).
6.4.2 Autoselect
By measuring the Autoselect resistance in the machine, the control
“recognizes” which machine series is connected. By means of
Autoselect control functions and the preset values of the parameters
are selected. If no Autoselect resistance or an invalid one is
recognized by the control, the drive will only run with the so-called
emergency operation functions in order to protect the machine from
being damaged.

7 Pneumatic connection
ATTENTION !
The pneumatic units will only operate properly at a supply
pressureof8to10bar.
The sewing machine’s operating pressure is 6bar.
Pneumatic connection package
Under the order number 0797 003031 a pneumatic connection
package for stands with compressed air maintenance unit is available.
It includes the following components:
–Connecting hose, 5 m long Ø = 9 mm
–Hose nozzles and hose clamps
–Coupling socket and connector plug
–Maintenance unit with manometer and pressure regulator
Connecting the compressed air maintenance unit
–Fasten the compressed air maintenance unit 2 to the stand strut
with angle, screws and flap.
–Connect the compressed air maintenance unit to the compressed
air supply with connecting hose 4 (Ø = 9 mm) and hose coupling
R1/4".
Setting the operating pressure
The operating pressure is 6bar.
It can be read off at manometer 3.
For adjusting the operating pressure raise and turn handle 1.
Increase the pressure = Turn twist handle 1 clockwise
Reduce the pressure = Turn twist handle 1 counter-clockwise
