1. Product description
The DÜRKOPP ADLER 577-1111 is an automatic double lockstitch
machine with bottom and top feed for sewing buttonholes with two
straight bars.
Normal sewing mode:
During the sewing process the fabric face ( the face seen) ) is up.
The machine can be supplied in three installation variants ( see on the
left ).
2. Normal use
The automatic sewing machine DÜRKOPP ADLER 577-1111 has been
designed for sewing light to middle-heavy weight material, as used in
the apparel industry.
Such material consists generally of textile or synthetic fibres.
Furthermore, the machine lends itself for producing so-called technical
seams. In this case, the user must estimate any possible dangers
(contact dürkopp adler ag for help), Technical seams are seldom, but
they may be very versatile. Proper safety precautions, depending on
the result of such an estimation, must be taken. Generally, only dry
material should be sewn on this machine. And the material should not
exceeded the thickness of
4 mm when compressed by the lowered sewing foot.
The material should not contain any hard objects, because otherwise it
would be necessary to protect the eyes during the sewing process..
For the time being, no such eye guard is available. The seams are
produced generally with threads up to 65/2 Nm ( cotton-covered
synthetic threads or synthetic threads ) Before using any other threads
it is necessary, also in this case, to estimate the consequential
dangers and to take, if necessary, the respective safety measures.
This automatic sewing unit should be installed and operated only in
dry and proper rooms. Otherwise, further precautions (to convene)
may be needed, ( siehe EN 60204-3-1:1990 ). We.manufacturers of
industrial sewing machines, assume, that our machines will be
operated at least by a well trained staff, knowing all usual controls and
any possible dangers.

4. Operation
4.1 Threading the needle
CAUTION: DANGER OF ACCIDENTS !
Turn off main switch!
Switch off the machine before threading the needle.
–Thread then needle according to the illustration.

4.2 Winding the hook thread
–Slip the reel onto its stand.
–Thread the hook according to the illustration.
–Slip the bobbin onto the bobbin winder 1.
–Wind the hook thread clockwise about 5 times around the bobbin
core.
–Swing bobbin winder lever 2towards the bobbin and let it snap.
–The thread will be wound during the sewing process.
–The bobbin winder lever 2 will stop the winding process as soon as
the bobbin is full.
–Following the winding process, tear off the bobbin thread at the
thread clamp 3.
4.3 Inserting the bobbin
CAUTION: DANGER OF ACCIDENTS !
Turn off main switch!
Switch off the machine before changing the bobbin!
Removing empty bobbin.
–Open hook space cover 4.
–Lift the bow 5and remove bobbin case top together with the
bobbin.
–Remove the empty bobbin from the bobbin case top.

Threading the bobbin
–Insert the full bobbin into the bobbin case top. When unwinding the
thread, the bobbin must turn clockwise.
–Pass the hook thread through the slit 6and under the spring 7.
–Depending on the buttonhole to be sewn, pass the hook thread
through the slit 9for a raised buttonhole ( more thread will be
advanced across the hook back) ) or through the slit 10 for a flat
buttonhole ( less thread ).
–Cut then the thread, passed as described, by the knife 11.
Adjusting the hook thread tension
–Adjust the hook thread tension by turning the screw 12 so that,
when holding the thread at its end, the bobbin case descends by
its own weight.
Inserting the bobbin case top
–Place the bobbin case top together with the bobbin onto the bobbin
case bottom and ensure that the bow 5snaps (what you should
hear).
–Close the bobbin space cover 4.

4.4 Changing the needle
CAUTION: DANGER OF ACCIDENTS !
Turn off main switch!
Switch off the machine before changing the needle!
Knife side
–Loosen the screw 1.
–Remove the neelde from its bar.
–Introduce the new needle as deep as possible into its bar a.
–Adjust the needle so that its furrow is located on the other side of
the knife.
–Tighten the screw 1.
NOTE !
The factory-set distance between the hook and the needle applies to
the needles having a thickness of 80.
When inserting a needle having a different thickness it may be
necessary to correct the distance ( see the Service Instructions ).

4.5 Lifting the sewing cage
The sewing cage 2will be lifted only if the main switch is turned on
and if following conditions exist:
–Sewing cage in initial position ( rear p. )
–Thread take-up lever in top dead-center position ( needle in upper
position )
If the thread take-up lever does not stand in its top dead-center
position ( error message in the display of the control panel: "_0 1 0" ),
the machine will automatically turn into this position after turning on
the main switch.
After turning on the main switch, following message will be presented
on the display of the control panel: "_0 1". if the sewing cage does
not stand in its initial position Turn then the crank until the sewing
cage stands in the proper position and can be lifted. By treading the
pedal forwards into its 1st position, the sewing cage will be lowered
without starting the sewing process.
The sewing cage can be lifted and lowered by the key 3 on the control
panel. Then it is necessary to switch on the parameter "F - 020" on
the operator level ( see chapter 4.9 ).
4.6 Regulating the sewing cage pressure
–The sewing cage pressure can be regulated by the screw 3.
