The current operating statuses are indicated on the control panel 1. The machine
is operated with constant dialogue between the control unit and the operator; different
pictograms and / or texts are displayed for this purpose according to the operating status of
the machine. Pictograms or texts with a border represent
functions that can be called up by pressing on the respective point on the monitor. Pressing
the respective function causes its immediate actuation or activation/deactivation or another
menu will appear, e.g. for entering a value. Activated functions are indicated by pictograms
shown inversely. Apart from the bobbin change function, the pictograms and texts without
border are only for display purposes and cannot be called up by pressing them. SD card 2 in the control panel can be used to import seam programs.

Fig. 8 - 01
 Loosen the screws 1 and 2
 Move the table top to the desired working height by pulling it out and pushing it in and
align the table top horizontally.
Adjust the stand on both sides evenly to prevent it tilting.
 The stand must have all four feet fi rmly on the ground to make sure it is positioned
securely.
 Firmly tighten the screw 1.
 Adjust and tighten the desired pedal position on the screws 2.

8.02 Initial commissioning
Before initial commissioning,
remove the protective fi lm from the sight glass 1.
 Clean the machine thoroughly and then
check the oil level, see Chapter 12
Maintenance and Care.
 Inspect the machine, particularly the
electric cable, for any damage.
 Arrange for technical staff to check
whether the machine's motor may be
operated at the existing mains voltage
and whether it is connected properly.
Never operate the machine if there are any differences.
The machine must only be connected to a grounded socket!
 With the machine running, the handwheel must turn towards the operator, otherwise ar-
range for technical staff to adjust the motor, see Chapter 13.07 Parameter settings.
 For machines with pneumatic devices, the machine must be connected to the
compressed air system. The manometer should show a pressure of 6 bar. Or set this value (see Chapter 12.04 Checking/setting the air pressure).
8.03 Switching the machine on/off
 Switch machine on and off (see Chapter 7.01 Main switch).

programs and programmed sewing.
The selection is made by selecting the corresponding program number: 0: Manual sewing 1 and 2: Sewing with fi xed programs 3 to 49: Programmed sewing (with up to 15 seam zones for left and right seams)
10.01 Manual sewing
In manual sewing, the values for the width and the target stitching position are displayed on
the control panel during sewing and can be changed directly by means of the corresponding
function, such as the functions at the seam end, the material type as well as the needle and
foot positions.
 Switch on the machine and select the program number "0", see Chapter 9.04 Selecting

10.01.01 Selecting material type
In order to obtain the same results (multiple widths) during the processing of different ma­terials, you can select between 3 types of material at any time in Manual Sewing and when
working with fi xed programs:
Material type light (here without quilting)
Material type medium (here without quilting)
Material type heavy (here without quilting)
The icon of the currently selected material type is displayed inversely.
For each material type, 4 different quilting levels can be selected. To do this, the symbol of
the corresponding material type has to be pressed until the appropriate fullness level ap-
pears in the display:
without quilting
approx. 80 g/m² quilting
approx. 200 g/m² quilting
approx. 400 g/m² quilting
Needle position raised
If this function is on, the needle moves to top position when sewing stops.
Thread trimming
- When the function is activated, thread trimming with the pedal function is possible
(optional).
- When switched on this function enables the edge knife to be switched off via pedal function, see Chapter 7.02 Pedal.
Presser foot up
When this function is activated, the presser foot is raised after sewing stops.

10.02 Sewing with fi xed programs
Fixed programs are set under the program numbers 1 and 2.
The fi xed programs are are used for the quick and easy sewing of seams with different full­ness. When sewing with fi xed programs, 2 or 3 seam areas are processed one after the oth-
er. The advance seam zone is effected by actuating the knee switch. The fi xed programs
are designed as concentric programs, meaning after the end of the last seam zone, the
fi rst seam area is started again. The value for the multiple width can be set for each seam
zone, the settings for the target stitch position as well as the needle and foot positions apply
across the entire area and can be changed at any time via the corresponding function.
 Switch on the machine and select the program number "1" or "2", see Chapter 9.04 Se-

These maintenance intervals are based on an average running time of a single
shift production shop. Shorter maintenance intervals are recommended for
increased running times.
12.02 Cleaning the machine
The required cleaning cycle for the machine depends on the following factors:
 Single or multi-shift operation
 Dust formation caused by the workpieces
Optimal cleaning instructions can therefore only be determined on a case-by-case basis
Disconnect the machine from the electricity mains for all cleaning work by
shutting off the main switch or removing the mains plug! Risk of injury due to
accidental machine start-up!
The following tasks are recommended
during single shift operation to avoid
operational errors:
 Tilt the machine backwards.
 Clean the hooks and hook area daily or
more often during continuous operation.
 When righting the sewing head, ensure
pressing the anti-tipping device 1.
Return the machine to its
upright position using both
hands!
Danger of injury by crushing
between the edge of the
machine and the table top.

Observe and comply with all instructions in the operating manual's chapter 1 Safety! In particular make sure that all safety covers are installed again
correctly after making adjustments, see chapter 1.06 Operating manual hazard information!
Unless otherwise stated, the machine must be disconnected from the mains before all adjustment work! Risk of injury due to accidental machine start-up!
13.01 Notes on adjustment
All adjustments in this manual are based on a fully assembled machine and may only be carried out by technical staff trained for this purpose. Machine covers, which have to be removed and replaced to carry out checks and adjustments, are not mentioned in the text. The order of the following chapters corresponds to the most logical work sequence for machines that have to be completely adjusted. Both the preceding and following chapters must be observed if only specifi c individual work steps are carried out. The screws and nuts indicated in brackets ( ) are fastenings for machine parts, which must be loosened before any adjustment and tightened again afterwards.

13.05 Checking and adjustment aid
By inserting the locating pins into the adjustment holes (ø 5 mm) 1, 3, 4, and 5 it is possible to precisely locate the needle bar position.
 Turn the handwheel until the needle bar is approximately in the required position.
 Place the adjustment pin in the corresponding adjustment hole and press it down.
 Turn the handwheel slightly back and forth until the adjustment pin engages the rear
crank cutout, blocking the machine.
Adjustment hole 1 = = top dead centre of the needle bar (t.d.c) Adjustment hole 3 = = below dead centre of the needle bar (b.d.c) Adjustment hole 4 = 0.8 mm before top dead centre of the needle bar
(0.8 in front of t.d.c.)
Adjustment hole 5 = 5.5 mm before top dead centre of the needle bar
(5.5 in front of t.d.c.)
