1. General Information
Attention!
The mains voltage and the nominal voltage listed on the
motor identification plate must be the same.
All work on the electronics is to be conducted only by au-
thorized personnel and with the mains plug disconnected.
Please observe all safety instructions!
Installation is to be conducted according to the following
instructions. All necessary parts are to be found in the en-
closed package.
1.1 Machine Operation without Material
Attention!
First arrest the pressure feet in the raised position and
set the shortest pressure foot stroke.
1.2 Table Tops The cutouts in self-made table tops must have the dimen-
sions shown in the sketches on pages 4 and 5.
The table tops must have the necessary load capacity
and firmness.

2. Frame Assembly
–Assemble the frame parts as shown and take care
that all feet touch the floor.
–Adjust the screws on the frame foot at the right back
accordingly for this.

3. Table Top, Completing and Screwing on
Underside of the Table Top:
- Screw on the cable duct 4 and the holder 5 for strain re-
liever
- Screw on main switch 2
- Screw on the sewing light transformer 1, if supplied
- Lay the electric wiring in the cable duct and to the motor
- Screw on the drawer 3 with mounting
- Screw on table top support plate 6 by frame MG56-2
- Screw the table top onto the frame with B8 x 35 wood
screws.

4. Connecting the Sewing Drive to the Table Top
4.1 General Different drive and connections packages are available
for the machine.
The drive package consists of:
Motor, motor protection switch with wiring, belt, belt pul-
ley.
The connectios package contains all wiring between the
motor and the sewing head.
The direct current drive available for this machine is ope-
rated by a "monophase alternating voltage". Therefore,
with multiple machines, the connections must be uniform-
ly distributed to the individual phases of the mains supply
(3 phase). Otherwise, this could lead to an overload of
the individual phases.
Attention!
If the electronics are not supplied by Dürkopp Adler, then
manufacture and testing is to be conducted to EN 60204-
3-1/JEC 204-3-1.
4.2 Drive Mounting
–Screw the drive with its base to the table top. Hereby
screw the 3 hex head M8 x 35 screws with washers
into the nuts in the table top.
–Fasten the V-belt pulley to the motor shaft
–Check the connections on the motor terminal board
and correct if necessary.
The arrangement must be appropriate to the mains
voltage.
4.3 Voltage Compensation Motor/ Machine Head
–Screw the green-yellow connecting cable found in
the enclosed package onto the motor base. It serves
to conduct the machine head static charge to ground
via the motor.

4.4 Attaching the Pedal and Rod.
For ergonomic reasons the lateral direction of the pedal is
to be aligned centered to the needle. Set the rod so that
the pedal has an incline of 10°.
4.5 Electrical Connections of the Motors
Please see the wiring diagrams enclosed in the drive
package for the necessary technical connections data.

5. Attaching the Machine Head
5.1 Mounting the Sewing Head, Establishing the Voltage
Compensation, Positioning the V-belt
–Mount the sewing head and fasten with three M8 x
95 Allan screws with washers and nuts.
–Establish the voltage compensation.
Screw the enclosed single-wire cable 1 to the sewing
head.
–Positioning the V-belt.
–Set the V-belt tension.
By swinging the motor, tension the V-belt so that it
can be pressed in at its center by about 10 mm
without great effort.
–Screw on the motor belt guard.
Set the cams so that the belt cannot slide out of the
V-belt pulley when the sewing machine is swung to
the back.

5.2. Attaching the Belt Guard, Mounting and Setting the Synchronizer
–Fasten the belt guard with 7 screws.
When tilting, the belt guard must go into the table top
cutout unimpaired.
–Screw on the synchronizer.
–Set the timing for "1st Position" and "2nd Position".
1st Position = Needle position slightly behind the
looping stroke.
2nd Position = Thread lever slightly before the
upper dead center.
Attention!
It is essential to set the timing for the 1st and 2nd position
as described above. The motor manufacturer’s instruction
give other values.

5.3 Connecting the Solenoid Valve Strip
–Plug the connection cable contact strip onto the so-
lenoid valves and fasten to the valves with two M 2,5
screws.

6. Connecting the Compressed Air Maintenance Unit
A supply of water-free compressed air is necessary for
the operation of the pressure foot stroke, stitch conden-
sing and thread trimming.
–Screw the maintenance unit onto the frame.
–Establish the PU3-hose connection between the
maintenance unit and the maschine head.
–Connect the maintenance unit connecting hose for
the maintenance unit to the compressed air supply.
–Pull up the handle 2 and set an operating pressure of
6 bar by turning.

7. Filling Oil and Readying the Machine for Operation.
–Mount the yarn stand.
–Fill "Esso SP NK 10" oil into both sewing head reser-
voirs up to the "MAX" marking.
–Connect the mains plug to the mains.
8. Conducting a Sewing Test.
With the maschine switched off thread the needle thread
and insert the bobbin.
(see Operating Instructions)
–Conduct a sewing test with material and set the need-
le and bobbin thread tension.
–First let the maschine run at low speed before se-
wing at higher speed.
