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
instructions marked by these signs.

6. Connecting the sewing drive
6.1 Connecting the sewing drive to the mains
ATTENTION !
Work of every kind on the electric equipment of the special sewing
machine must only be carried out by electricians or correspondingly
trained personnel.
The mains plug has to be pulled out!
The manufacturer’s operating instructions enclosed to the sewing
drive have to be observed in any case!
6.1.1 Connecting the clutch motor
–Run the connection cable from the main switch through the cable
duct to the sewing drive and connect it to the sewing drive.
See connecting diagram 9800 169002 B (in the connection
package) or wiring diagram at the clutch motor.
–Run the mains cable from the main switch through the cable duct to
the back and fasten it with the strain relief clamp.
6.2 Mounting the sewing lamp (optional equipment)

–Plug the cable to the sewing machine into bushing A of the control.
–Run all cables through the cable duct.
–Cable of the control panel (optional equipment) into bushing B776.
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 setting of parameters.
Upon delivery of the sewing drives the parameter values are preset by
Efka (preset values). For every class and subclass some parameters
have to be changed in the „technician level" and some in the „supplier
level" in order to optimally adapt the control to the machine. The
parameters concerned are listed on the parameter sheet (in the
accessories) .
The parameter 290 (selection of the machine class) has to be set to
the value 1 (for cl. 171) / value 2 (for cl. 173) in the “supplier level”.
Furthermore, the parameter 170 (setting of the reference position) has
to be set in the “technician level”. The setting “position (EP)” is the
penetration point of the needle into the throat plate.
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 run with the so-called
emergency operation functions only in order to protect the machine
from being damaged.

7. Adjusting the sewing drive
7.1 Rotation sense of the sewing drive
Attention!
Before putting the special sewing machine into operation check the
rotation sense of the sewing drive by all means!
Operating the special sewing machine with a wrong rotation sense
may cause damage.
7.1.1 Checking the rotation sense of clutch motors (to be mounted under the table top only)
The rotation sense of the clutch motor (three-phase a.c. motor) is
dependent on the connection to the three-phase supply network.
Before the start of operation the rotation sense has to be checked.
Please proceed as follows:
–Connect the clutch motor, make the potential equalisation and
connect the sewing drive to the mains.
(see chapter 6.1.1 and 5.3)
–Switchthemainswitchon.
–Actuate the pedal (or the clutch lever of the motor respectively),
until the belt pulley rotates.
–The belt pulley must rotate counter-clockwise (view on the belt
pulley).
7.1.2 Changing the rotation sense of clutch motors (to be mounted under the table top only)
If the rotation sense of the sewing drive is wrong, two phases have to
be exchanged at the clamps of the mains connection of the sewing
drive. Please proceed as follows:
–Switch the main switch off and pull out the mains plug!
–Exchange two of the three live power supply conductors at the
mains connection of the sewing drive.
–Plug in the mains plug and switch the main switch on.
–Check the rotation sense (see chapter 7.1.1).
