The
materials. As a rule such materials are fabrics consisting of textile fibres, but they also
include leather. They are used in the clothing, domestic-upholstery and
automobile-upholstery industries.
This special sewing machine can also be used to execute so-called technical seams.
However, the operator must carry out an assessment of the p ossible dangers (wit h
which
comparatively unusual and they are potentially of enormous diversity. Depending on the
outcome of this assessment it may be necessary to take special safety precautions.
Generally speaking material processed with this special sewing machine must be dry,
its thickness when compressed by the lowered sewing fe et must not exceed 10 mm and
it must contain no hard objects, since otherwise the operator of the machine would have
to wear protective goggles (which cannot at present be supplied).
The seam is gene rally executed with tex tile-fibre sewing thr eads of dimensions up t o
11/3 NeB (cotton thread), 11/3 Nm (synthetic thread) or 11/4 Nm (covering yarn). The
use of any ot her threads must a lso be subject to an assessment of the risks involved
and the taking of any necessary safety precautions.
The premises in which this special sewing machine is set up and operated must be dry
and well-maintained. If it is to be used in premises which are not dry and
well-maintained, special precautions may be necessary: these must be the subject of
an agreement (see EN 60204-3-1:1990).
As manufactu rers of industrial se wing machines we work on the assumption that
personnel working on our machines will be at least semi-skilled, so that they can be
presumed to be familiar with all normal operations and with the dangers inherent in
them.

–
Adjust preliminary tension 1 by rota t i ng the Knurled nut.
–
After major changes to prelimin ary tension 1 the ma i n tension 3 should als o be
adjusted accordingly.
Main tension 3
The main tension 3 should be set as low as possible.
The looping of the threads must be in the centre of the material (see fig. a).
With thin material excessive thread t ension can cause unwanted gathering and thread
breakage.

5.4 Winding on the looper thread
Caution - danger of injury
Turn off the main switch.
The looper thread may be threaded for winding on only
when the sewing machine is switched off.
–
When winding on for sewing with no underlay material:
arrest the sewing feet in the up position (see chapter 5.9).
–
Thread looper thread as shown in the upper illustration.
–
Wind about 5 coil s of looper thread anti -clockwise onto the bobbin core.
–
Place bobbin on bobbin winder 2.
–
Swivel bobbin-winder lever 3 against the bobbin.
–
Adjust tension 1.
The looper thr ead should be wound on with minimal tension .
–
Sew.
The bobbin-wi nder lever 3 terminates the process as soon as t he bobbin is full.
5.5 Fitting the looper-thread b obbin
Caution - danger of injury

5.6 Adjusting looper-thread tension
Caution - danger of injury
Turn off the main switch.
The looper-thread tension may only be adjusted with the
sewing machine switched off .
Adjusting tensioning spring 2
–
Release right-hand needle-plate s l i de and push aside.
–
Adjust tensioning spring 2 by rotating regulating screw 1.
To increase looper-thread tension:= rotate screw 1 clockwise
To decrease looper-thread tensi on= rotate screw 1 anti-clo ckwise
–
Push needle-plate slide back into place.
Note:
The conical spri ng in the bobbin housing has the following functions:
–
When the bobbin-housing shutter is open it raises the bobbin slightly for removal.
–
It prevents the bobbin from "running on" when the machine halts or if the looper
thread is wound off spasmodically.
5.7 Fitting and replacing the needle
Caution - danger of injury
Turn off the main switch.
The needle may o nl y be changed with the sewing machine
switched off .
–
Rotate the ha ndwheel until the needle bar 3 has reached its uppermost position.
–
Undo screw 4.
–
Draw the needl e downwards out of the needle bar 3.
–
Insert a new needle as far as it will go into the hole in the needle bar 3.
Important
When viewed from the operating side of the sewing machine the furrow 5 of the
needle must point to the right (see sketch).
–
Tighten screw 4.
IMPORTANT
When fitting a thicker needle the distance of the shuttle
from the needle must be corrected (see Servicing
instructions).
Failure to comply with the above note may lead to the following errors:
when fitting a thinner needle: faulty stit ches, damage to thread
when fitting a t hicker needle: damage to the shutt l e t i p and needle

5.8 Lifting the sewing feet
With the machine at a halt the sewing feet are mechanically raised with knee lever 1:
–
Operate knee lever 1.
–
The sewing feet remain lifted for as long as knee leve r 1 is operated.
5.9 Arresting the sewing feet in the up position
The mechanically lifted sewing feet are arrested in the up position with lifting lever 2
(e.g. to wind on the looper thread or replace the sewing f oot).
Lifting lever 2 is located at the rear of the machine arm.
Caution - danger of injury
Turn off the main switch.
Only arrest the sewing feet with the sewing machine
switched off .
–
Swivel lifting lever 2 downwards.
The sewing feet are arrested in the up pos ition.
–
Swivel lifting lever 2 upwards.

sewing machine switched off .
Adjusting the sewing-foot stroke
–
Press button 3 and hold it down.
–
Rotate handwheel 4 until it locks.
–
Continue to rotate the handwheel until the required letter (items A - F) appears in
inspection window 5.
item A: minimum sewi ng-foot stroke (1.5 mm)
item F: maximum sewing-foot stroke (6 mm)
IMPORTANT
Sewing-foot stroke, stitch length and stitch rate are
mutually inte rdependent.
To ensure reliable operation and a long machine life, do not
exceed the maximum stitch rate given in the table.
15
5.11 Adjust ing the sewing-foot pressure
1 2 3
The required sewing-foot pressure is set with knob 1 .
–
To increase sewing-foot pressure = turn knob 1 clockwise
To decrease sewing-foot pressure = turn knob 1 anti-clockwise
5.12 Adjusting the stitch length
–
Set the required stitch length with knob 2.
To increase sti tch length = turn knob 2 cl ockwise
To decrease stitch length= turn knob 2 anti-clockwise
–
To sew bar tacks manually press stitch-regulating lever 3 downwards.
The machine sews backwards for as long as stitch-regulating lever 3 is held down.
The stitch length is the same as that set for forwards sewing.

6. Control unit and operating panel
IMPORTANT
This operating m anual covers
change of parameters by the operator.
For a detailed description of the control unit please see the
motor manufacturer’s current operating manual (attached).
6.1 General
The operating panel is used to pro gram the control un i t and to set the seam f unctions.
Depending on the nature of the job, sewing may be executed manually or by seam
programming.
For differing jobs seams can be prog rammed for which th e functions (starting bar tack,
ending bar tack, stitch count, thread cutting etc.) and parameter values (stitch rate,
seam length, rpm etc.) are indiv i dually assigned.
Entry is carried out in programming mode.
The paramete rs and the values assigned are displayed.
The seam progr a m s are not lost even w hen the sewing machine is switched off (battery
buffer).
In order to a void the inadverten t alteration of pre-set functions, operation is divided i nto
various levels (operator, technician, fitter).
The operator (seamstress) can progra m di rectly.
On the other levels access is contingent on the entry of a code number (EFKA).
