Operating instructions

Risk of injury by the needle point and moving
parts.

Switch off the sewing machine before replacing the
needle.

Do not touch the needle point.

WARNING

Damage to the looper point or needle possible due to incorrect
distance from the looper.

The distance between the looper and the needle only needs to be
adjusted if the new needle has a different size.

After changing the needle size, adjust the looper distance.
For this, read the service manual.

• Turn the bobbin clockwise until it clicks.

• Pull the bobbin lever (3) up.

The looper thread is normally wound on when sewing is in progress. How­ever, you can also wind on the looper thread without sewing material,
e.g. if you require a full bobbin in order to start sewing.

Operating instructions

Damage to the sewing feet or needle plate possible if the
thread is wound on without material.

Lock the sewing feet in place in the highest position and adjust the
sewing foot stroke to the smallest value if you wind on thread with­out sewing material.

ATTENTION

Risk of injury by the needle point and moving
parts.

Switch off the sewing machine before replacing the

Note for machines with automatic residual thread monitor:

If the looper thread needs to be replaced, the LED indicator lamps (1) light
up on the machine arm. The left light is for the left-hand looper and the
right light is for the right-hand looper.

The bobbin plate has vision slots on one side.

• Insert the bobbin in the looper in such a way that the vision slots (2)
are at the top.

Otherwise the residual thread monitor will not work.

7.7 Adjusting the thread tension

The tension of needle thread and looper thread determines the position of
the thread interlacing.
If the tension of needle thread and looper thread is high, the thread inter­lacing lies in the middle of the material to be sewn.

7.7.1 Adjusting the needle thread tension

The three tension-adjusting wheels determine the needle thread tension.

(1) - Pre-tensioner
(2) - Additional tensioner
(3) - Main tensioner

Figure 14: Adjusting the needle thread tension

The main tension (3) determines the normal tension during sewing.
The additional tension (2) increases the tension during sewing, e.g. for
thickened seams. The additional tension (2) is switched on and off using
the keypad.

• The additional tension (2) must always be selected lower than the
main tension (3).

In the basic position, the top of the adjusting wheel is flush with the screw
in the center.

To increase the tension:

• Turn the adjusting wheel clockwise.

To reduce the tension:

• Turn the adjusting wheel counterclockwise.

The preliminary tension (1) holds the thread in position if main
tensioner (3) and additional tensioner (2) are open completely.

Note for machines with automatic thread cutter:

The preliminary tension (1) also determines the length of the initial thread

Automatic

for the new seam:
Short initial thread:

• Turn the adjusting screw of the pre-tensioner (1) clockwise.

Long initial thread:

• Turn the adjusting screw of the pre-tensioner (1) counterclockwise.

To reduce the tension:

• Turn the adjusting screw (1) counterclockwise.

7.8 Setting the thread regulator

The thread regulator determines the tension applied to guide the needle
thread around the looper.

Correct setting:
The loop of the needle thread slides at low tension over the thickest point
of the looper.

7.9 Lifting the sewing feet

You use the foot pedal during sewing, e.g. to move the material being
sewn.

(1) - Foot pedal

Figure 17: Foot pedal

• Press the foot pedal (1) half the way back.

The machine stops and lifts the sewing feet. The sewing feet remain up as
long as the foot pedal is pressed back half the way.
If the foot pedal is pressed back completely, the machine sews an end
strip and stops sewing. Machines with automatic thread cutter cut the
thread off.

7.10 Locking the sewing feet in the upper position

There is a lever at the back of the machine for holding the sewing feet in
the upper position.

(1) - Sewing feet in upper position
(2) - Upper position canceled

Figure 18: Holding the sewing feet in the upper position with the lever

To hold the sewing feet in the upper position:

• Push the lever down.

To cancel the lock:

• Push the lever up.

You can also use the foot pedal to cancel the upper position:

• Press the foot pedal half the way back like for lifting the sewing feet.

The lever swivels back up and the lock is removed.

7.11 Sewing foot pressure

The adjusting wheel at the top left determines the contact pressure of the
sewing foot on the material to be sewn. The pressure can be adjusted con­tinuously by turning the wheel.

q

Figure 19: Adjusting wheel for the sewing foot pressure

To increase the sewing foot pressure:

• Turn the adjusting wheel (1) clockwise.
To reduce the sewing foot pressure:

• Turn the adjusting wheel (1) counterclockwise.

7.12 Sewing foot stroke

The two adjusting wheels in the middle of the machine arm determine how
high the sewing feet are raised during sewing. The height can be adjusted
continuously on a scale from 1 to 9 by turning the wheels. With 1 the sew­ing foot is raised the least and with 9 it is raised the highest.

q

Figure 20: Adjusting wheels for the sewing foot stroke

To increase the sewing foot stroke:

• Turn the adjusting wheel clockwise.
To reduce the sewing foot stroke:

The left adjusting wheel (1) determines the normal sewing foot stroke.
The right adjusting wheel (2) determines the elevated sewing foot stroke.
It is used for example when sewing thicker parts of the material.

The machine is designed in such a way that the sewing foot stroke
at the right adjusting wheel cannot be set lower than at the left

Do not attempt to use brute force to set a smaller sewing foot stroke
at the right adjusting wheel.

ATTENTION

Figure 21: Knee lever

The elevated sewing foot stroke is activated using the knee lever (1).
There is a switch (2) at the back of the knee lever (1), which determines
whether the sewing foot stroke is applied continuously or only as long as
the knee lever is pressed.

For permanent conversion:

• Turn the switch (2) up

To switch on the elevated sewing foot stroke:

• Push the knee lever (1) to the right.

To switch off the elevated sewing foot stroke:

• Push the knee lever (1) to the right again.

For temporary conversion:

• Turn the switch (2) down

To switch on the elevated sewing foot stroke:

• Push the knee lever (1) to the right and keep it pressed.

The elevated sewing foot stroke is retained as long as the knee lever is
pushed to the right.
To switch off the elevated sewing foot stroke:

• Release the knee lever (1).

The elevated sewing foot stroke must not be lower than the normal sewing
foot stroke. Always set the sewing foot stroke at the right adjusting wheel
in such a way that it is at least as high as the sewing foot stroke at the left
adjusting wheel.

The machine automatically adapts the number of stitches to the sewing
foot stroke. If you increase the sewing foot stroke, the number of stitches
will be reduced.

Key for sewing backwards (1):

If the key (1) is selected the machine sews backwards.

Key for the position of the needle (2):

If the key (2) is selected the needle moves to a specific position. This posi­tion is determined individually via the parameter settings. For this, read the
service manual. On delivery, the machine setting is such that the needle
is moved up if the key (2) is selected.

Key for the start and end strips (3):

Key (3) cancels the general setting for sewing start and end strips. If strips
are switched on, pressing the key (3) disables the next strip. If no strips
are switched on, pressing the key (3) sews the next strip.
For the general setting for sewing start and end strips, refer to the manual
