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
automobil e-upholstery industri es.
This special sewing machine can also be used to execute so-calle d technical se ams.
However, the operator must c arry out an assessment of t he possible dangers (wit h
which
comparatively unusual and they are potentially of enormous diversity. Depending on the
outcome of this asse ssment it ma y be necessary to take sp ecial safet y precautions.
Generally speaking material processed with this special sewing machine must be dry,
its thickness when com pressed by the l owered sewi ng feet must not exceed 10 m m 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 generally execu ted with text i l e-fibre sewing threads of dim ensions up to
11/3 NeB (cotton thread), 11/3 Nm (synthetic thread) or 11/4 Nm (covering yarn). The
use of any other threads must also be subje ct to an asse ssment of the risks involved
and the taking of any necessary safety precaut i ons.
The premises in which this special sewing machine is set up and operated must be dry
and well-mai ntained. If it is to be used in premises whi ch 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 manufacturers of in dustrial sew i ng machines we work on the assumption t hat
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.

adjusted accordingly.
machine the needle thread needs t o be under re sidual tensi on for
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 ma terial excessiv e t hread tensio n can cause unw anted gathering and threa d
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 coils of looper thread anti -clockwise onto the bobbin core.
–
Place bobbin on bobbin winder 2.
–
Swivel bobbin-winder lever 3 again st the bobbin .
–
Adjust tension 1.
The looper thread should be wound on with minimal tension.
–
Sew.
The bobbin -winder lever 3 terminates t he process as so on as the bobbi n i s full.
5.5 Fitting the loop er-thread bob bin
Caution - danger of injury
Turn off the main switch.
The looper-thread bobbin may only be changed with the
sewing machine at a halt.
Removing empty looper-thread bobbin
–
Press leaf s p ring down an d push right-hand needle-plate slide aside.
–
Raise bobbin-housing shutter 4.
–
Remove empty looper-thread bobbin.
Threading looper thread
–
Place full bobbin 8 in bobbin housing:
when the thread is wound off the bobbin must rotate in the direction of the arrow.
–
Draw looper thread through slit 5 down to tensioning spring 7.
–
Draw looper thread into slit 6.
–
Cut looper thread to a length of about 3 cm.
–
Close bobbin-housing shutter 4.

5.6 Adjusting loop er-thread t ension
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 sli de and push aside.
–
Adjust tensioning spring 2 by rotating regulating scr ew 1.
To increase looper-thread tension:= rotate screw 1 clockwise
To decrease l ooper-threa d tension= rotate screw 1 anti-clockwi se
–
Push needle-plate slide back into place.
Note:
The conical s pring in the bobbin housing has the follow i ng 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 only be changed with the sewing machin e
switched off.
–
Rotate the handwheel until the needle bar 3 has re ached its uppe rm ost position .
–
Undo scre w 4.
–
Draw the ne edle 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 thinn er needle: faulty st i tches, damage to thread
when fitt i ng a thicker needle: damage to the shuttle 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 f eet remain l i f ted for as long as knee lever 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 wi nd on the looper thread or replace the sewing foot).
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 f eet are arrested i n t he up position .
–

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 sewing -foot stroke (1.5 mm)
item F: maximum sewing-foot stroke (6 mm)
IMPORTANT
Sewing-foot stroke, stitch length and stitch rate are
mutually interdepende nt.
To ensure reliabl e operation a nd a long machine life, do no t
exceed the maximum stitch rate given in the table.

5.1 1 Adjusting the sewin g-foot pressure
1 2 3
The required sewing- f oot 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 st i tch length = turn kno b 2 clockwise
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 manual cov ers
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 operati ng panel is us ed to program the contro l unit and to set the seam functions.
Depending on the nature of the job, sewing may be executed manually or by seam
programming.
For differing jobs seams can be programmed for which the functions (starti ng bar tack,
ending bar tack, stitch count, thread cutting etc.) and parameter values (stitch rate,
seam leng t h , rpm etc.) are individual l y assigned.
Entry is carried out in programming mod e.
The paramet ers and the v al ues assigned are displayed.
The seam programs are no t l ost even when the sewing machine is swi tched off (ba ttery
buffer).
In order to avoid the inadvertent alteratio n of pre-set f unctions, op eration is divided into
various levels (operator, technician, fitter).
The operator (seamstress) can program di rectly.
On the other levels access is contingent on the e nt ry of a code number (EFKA).
