1. Product Description
The
DÃœRKOPP ADLER 271-274
are universally employable special sewing machines.
2. Proper Use
The
271-274
are special sewing machines which can properly be used for the sewing of
light weight material. Such material is, as a rule, material made up of textile fibers or
leather. These materials are used in the garment and home upholstery industries.
Further, it may be possible to also conduct so-called technical seams with these special
sewing machines. Here, however, the operator (
DÃœRKOPP ADLER
would be pleased to
collaborate) must make an evaluation of the possible dangers because such
applications are, on the one hand, comparatively rare and, on the other, the variety is
immense. Dependent on the result of this evaluation, appropriate safety measures are
to be taken.
Generally, only dry material may be worked with these special sewing machines. The
material may be no thicker than 6 mm when pressed together by the lowered sewing
foot. The material may not contain any hard objects because otherwise the automatic
sewing unit could only be operated with eye protection. Such eye protection is not
available at this time.
The seam is generally sewn with sewing yarns of a dimension up to 30/2 Nm (synthetic
threads) or 30/3 Nm (core spun threads). Those desiring to use other threads must first
estimate the dangers arising therefrom and, if necessary, take appropriate safety
measures.
These special sewing machines may only be installed and operated in dry and clean
premises. If the sewing unit is used on other premises which are not dry and clean,
further measures, which are to be agreed upon, may be necessary (see
EN 60204-31:1999).
We, as a manufacturer of industrial sewing machines, assume that at least semi-skilled
operating personnel will be working on our products so that all normal operations and,
where applicable, their dangers are presumed to be known.

6. Operation
6.1 Threading the Needle Thread
Caution Risk of Injury !
Turn the main switch off !
Thread the needle thread only with the sewing machine
turned off.
–
Place the spool of yarn on the yarn stand as shown in the illustration (Page 14).
–
Thread the needle thread according to the drawing on the previous page.
6.2 Setting the Needle Thread Tension
Setting of the needle thread pretension
The main tension 4 of the needle thread is open during the thread trimming. For a
secure thread trimming, it is, however, necessary that the needle thread remains
slightly taut during thread trimming. This is achieved through the needle thread
pretension 1. At the same time, the needle thread pretension 1 influences the length of
the cut needle thread end and, thereby, the thread length which is required for the next
secure seam beginning.
Base position: Turn knurled nut 2 until its front lies flush with bolt 3.
Shorter beginning thread: Turn knurled nut 2 clockwise
Longer beginning thread: Turn knurled nut 2 counterclockwise.
Note: After greater changes in the needle thread pretension
the main tension 4 may possibly need correction in
order to achieve the same sewing results.
Setting the main tension
The needle thread pretension 1 and main tension 4 together build the thread tension
required for the seam (see Illus. a).
Setting: Turn knurled nut 4 accordingly
Increase tension: Turn knurled nut 4 clockwise
Decrease tension: Turn knurled nut 4 counterclockwise
6.3 Releasing the Needle Thread Tension
Automatic
The main tension 4 is automatically opened during thread trimming.

6.5 Inserting the Underthread Bobbin
Caution Risk of Injury !
Turn the main switch off.
Insert the underthread bobbin only with the sewing
machine turned off.
Removing the bobbin
–
Lift the bobbin case retainer 1.
–
Remove hook base 2 with bobbin.
–
Remove the empty bobbin from hook base 2.
Inserting a full bobbin
–
Place full bobbin 3 into hook base 2.
–
Pull the underthread through the slit 4 under tension spring 6 and into the drilled
hole 5.
–
Pull the underthread approx. 5 cm out of hook base 2.
When the thread is pulled off, the bobbin must turn in the direction of the arrow.
–
Insert the hook base 2 into the hook again.
–
Close the bobbin case retainer 1.

6.6 Setting the Underthread Tension
Caution Risk of Injury !
Turn the main switch off.
Setting the underthread tension only with the sewing
machine turned off.
Setting the underthread tension
The underthread tension must be set so that a seam as shown in Illus. a)
in Chapter 6 results.
–
With a recommended underthread tension of e.g. 30g, 15g should be achieved
through the brake spring 1 and 15g through the tension spring 4.
–
The following applies as the base setting for the tension spring 4:
The bobbin case must slowly lower under its own weight. See sketch in Chapter 6.5.
The brake spring 1 hinders a running-on of the bobbin during the thread trimming
sequence.
To regulate the two tension values one proceeds as follows:
–
Turn adjusting screw 3 back so far that the tension of the tension spring 4 is
completely released.
–
Set the brake spring 1 by turning the screw 2 so that half of the recommended
hook thread tension value is achieved through the brake spring.
Attention !
Not for classes: 271-140432, 271-140442, 273-140432
–
Insert the bobbin into the hook base and thread the underthread (see Chapter 6.5).
–
Insert the bobbin case with the bobbin into the hook.
–
Turn the handwheel until the sewing machine has conducted a stitch.
–
Pull the underthread to the top of the needle hole with the aid of the needle thread.
–
Pull off the underthread in the direction of sewing at an angle of 45°. About half of
the tension value should be felt.
Then tighten the adjusting screw 3 to the recommended tension value.

6.7 Changing Needles
Caution Risk of Injury !
Turn the main switch off.
Change the needle only with the sewing machine turned off.
–
Loosen screw 1 and remove the needle.
–
Push the new needle up to the stop into the drilled hole in the needle bar 4.
ATTENTION !
The furrow 2 must face the hook point 3 (see sketch).
–
Tighten screw 1.
ATTENTION !
After a change to a different needle thickness, the
clearance of the hook to the needle must be corrected (see
Service Instructions).
Not observing the above correction can lead to the following errors:
–
Change to a thinner needle: - Missing stitches
- Damage to the thread
–
Change to a thicker needle: - Damage to the hook point
- Damage to the needle
