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

2. Use in accordance with the requirements
Class 910 is a sewing unit determined for processing light to
medium-weight material, i.e. fabrics made of textile fibres or leather.
Such sewing materials are used in the clothing industry and for the
production of home and car upholstery.
Furthermore, this sewing unit can also sew so-called technical seams.
However, in this case the user has to es timate the possible risks
(preferably in c ooperation with DÜRKOPP ADLER AG) because on the
one hand such fields of application are comparatively rare and on the
other hand there is an immense variety of possibilities. According to
the result of this estimation suitable safety measures may have to be
taken.
Generally only dry fabrics must be processed on this sewing unit. The
material must not be thicker than 10 mm when compressed by the
lowered fabric clamp. It must not include any hard objects.
In general the seam is produced with sewing threads made of textile
fibres (cotton threads, synthetic threads or core threads) with the
following dimensions:
Class 910 threads of the dimension 15/3 - 120/3
If other threads are to be used, it is indispensable also in this case to
consider the possible risks and to take corresponding safety
measures, if necessary.
This sewing unit must only be installed and operated in dry and
well-kept rooms. In case it is operated in other rooms which are not dry
and well-kept further measures can become necessary which have to
be agreed upon (see EN 60204-31: 1999).
We as manufacturers of industrial sewing machines take it for granted
that at least semi-skilled operators are working with our products so
that we can assume that all usual operations and their risks are known
to them.

7.2 Threading in the needle thread
Caution: Risk of injury!
Switchthemainswitchoff!
Thread in the needle thread only with the sewing unit switched off.
–
Stick the thread reels on the thread reel holder and guide the
needle thread and the
bobbin thread through the unwinding arm.
The unwinding arm must be positioned vertically above the thread
reels.
–
Thread in the needle thread as shown in the illustration below.

Caution: Risk of injury !
Switchthemainswitchoff.
Adjust the thread regulator only with the sewing unit switched off.
With the thread regulator 3 the needle thread quantity required for the
stitch formation is regulated.
Only a precisely adjusted thread regulator guarantees an optimum
sewing result.
When the thread regulator is adjusted correctly, the needle thread loop
must slide over the thickest spot of the hook with low tension.
–
Loosen screw 1.
–
Change the position of the thread regulator 3.
Thread regulator to the left = larger needle thread quantity
Thread regulator to the right = minor needle thread quantity
–
Tighten screw 1.
Adjustment hint:
If the largest thread quantity is required, the thread controller s pring 2
must be pulled up by approx. 0.5 mm from its lower end position. This
is the case when the needle thread loop passes the maximum hook
diameter.

–
Wind the thread counter-clockwise around the core of the bobbin
(approx. 5 times).
–
Press the winder lever 3 into the bobbin.
–
Sewing
The winder lever stops the winding process as soon as the bobbin
is full.
–
