1. General Information
1.1 Safety Notes
Special 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 authorized personnel and with the mains plug
disconnected.
Please observe the safety instructions!
Installation is to be conducted according to the
following instructions. All necessary parts are to be
found in the enclosed package.
1.2 Machine Operation without Material
Attention!
First arrest the pressure foot in the open position
and set the shortest pressure foot stroke.
1.3 Table Tops
The cutouts in self-made table tops must have the
dimensions shown in the sketches on pages 4 and 5.
The table tops must have the necessary load
capacity and firmness.

Underside of the Table Top
–
Fasten the reinforcement brace 5 with 4
screws between the cutouts of the sewing
head and the belt guard.
–
Mount the oil baffle 4 with wood screws. Align
the oil baffle so that the distance from the right
side of the oil baffle to the table top cutout is
55 mm.
–
Screw on the reinforcement brace 7 behind the
oil baffle.
–

the connection cable strain reliever.
–
–
Screw on the main switch 2.
Screw on the sewing light transformer 1 (if
supplied).
–
Screw on the drawer 8 with its mounting.
Secure the insert plate against displacement
with a nail.
–

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 pulley.
The connections package contains all wiring
between the motor and the sewing head.
The direct current drive available for this machine
is operated by a "monophase alternating voltage".
Therefore, with multiple machines, the connections
must be uniformly 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 3 M8 x 35 hex head screws with
washers into the nuts in the table top.
–
–
Fasten the V-belt pulley to the motor shaft.
Check the arrangement of 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
–
8
Screw the connecting cable found in the
enclosed package onto the motor base. It
serves to conduct the static charge of the
machine head 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 connection of motors
The required technical connecting data are listed
in the circuit diagram enclosed in the drive
package.

5. Positioning the Machine Head, V-belt Placement,
Attaching the Belt Guard and Handwheel
2

10
–
Set the sewing head into the table top cutout.
–
Fold over the sewing head and remove the
safety bar 1.
–
Plug the arresting pin 2 into one of the notches
of the built-in adjustment disc.
–
–
Screw off the handwheel.
–
Place the belt on the motor belt pulley.
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 belt guard with 5 screws.
When folding over, the belt guard must go into
the table top cutout unimpaired.
–
Screw on the motor belt guard.
Set the securing cams so that the belt does
not slip out of the belt pulley when the sewing
head is folded over.
–
Screw on the handwheel.
The correct position of the handwheel is
derived from the additional holes in the hand
wheel and on the belt flange. They must lie
congruent.
First place the V-belt over the machine belt
pulley.
6. Making the Plug Connections to the Motor Control,
Attaching the Synchronizer (Only Positioning Drive)
2

–
–
–
–
Fold over the machine
Connect the voltage compensation lead 1 to
the head.
If supplied, connect the external control panel.
Lay the wiring for buttons, control panel and, if
supplied, sewing light in the head cable duct.
Attention!
Before installing the synchronizer, switch off
the thread trimmer function on the control
panel.
–
With the machine switched off, push the
synchronizer onto the handwheel so that its
groove catches over the mounting pin on the
belt guard.
–
–
Arrest the handwheel in position A.
Screw on the synchronizer.
Position the marking 2 directly opposite the
notch 3.
This is position "0", the dependent initial
position for all machine position settings made
at the factory.
For setting the 1st and 2nd needle positions
see Section 9.

7. Connecting the Compressed Air Maintenance Unit
1
5
2
For operation of the pressure foot stroke, stitch
condensation and thread trimming, a supply of
water-free, lightly oiled compressed air is required.
–
–
Screw the maintenance unit to the frame.
–
With the compressed air disconnected or shut
off, fill lubricating oil ESSO SP-NK 10.
Open screw 2 and fill up to the grooved
marking.
–
Connect the maintenance unit connector hose
to the compressed air supply.
–
Pull up the handle 5 and set an operating
pressure of 6 bar by turning.
Establish the PU3-hose connection 1 between
the maintenance unit and the machine head.
8. Readying the Machine for Operation
12
–
–
Mounting the Yarn Stand
–
–
Plug in the mains plug.
–
Check the feed quantity of the oil mister
(approx. 1 drop every 10 work cycles). Correct
if necessary. See Section in the Operating
Instructions.
Fill the oil tank for the central oil wick
lubrication up to the upper marking line (see
Operating Instructions Section 2.1)
Briefly switch on the motor protection switch
for three phase motors.
Check the direction of rotation on the motor
ventilation wheel. See arrow on the belt guard.
If the direction of rotation is incorrect
interchange 2 phases in the mains plug.
5.1 Fitting oil recycling device
The oil recycling device collects the oil in the oil
sump and returns it by apump to the oil circuit.
–
Wrap intake filter 3 of the oil recycling device
by the felt and fasten it to the oil sheet by the
clamp 2.
–
Install the oil hose 1 and secure it so that it
cannot get into contact with mobile parts.

ATTENTION !
Change the oil every 2 years, irrespective of the
number of operating hours.
9. Setting the Synchronizer
The machine positions are seen by the
synchronizer in steps (increments) of 0.7° and
shown in the display. A complete revolution
corresponds to 512 steps.
1st Position
The machine should stop when the hook has
securely taken up the loop.
This means that the needle should raise above its
lower dead center until the hook tip has moved
approx. 6 mm above the needle to the left. This
corresponds to the increment number 50.
2nd Position
Needle bar a little bit before the upper dead center.
This corresponds to the increment number 190.
