Fabric, needle and thread table
Only use needles of the130/705 H system. We recommend using the stretch needle 130/705 H-S for
sewing elastic fabrics and knitwear and the jeans needle 130/705 H-J for sewing heavy fabrics.
Needles and threads must be selected according to the fabric that is to be sewn. Always use thread of
the same weight and the same material for the upper and lower threads. Good sewing begins with
high-quality, sharp and straight needles and the matching sewing thread. The table below is provided as
an aid in this regard:

Changing a needle
Caution
• Switch off the machine at the power switch (“0”) before changing the needle. If the foot controller
is accidentally pressed while the machine is switched on, the machine is started and serious
injuries may occur.
• Only use needles of the 130/705 H system.
• Do not use bent needles for sewing (risk of injury).
Checking the needle
In order to check the needle, place it on an
even surface with the flat side down. Check
the needle from above and on all sides. Do not
use bent needles!
1 Parallel distance
2 Place the needle on an even surface
(needle plate, glass, etc.)
Inserting the needle
1 Turn the hand wheel (anti-clockwise) until
the needle is in the highest position.
2
Switch off the machine at the power
switch.
3 Lower the presser foot lifter.
4 Loosen the screw and remove the needle
downwards.
5 Push the needle with the flat side facing
backwards up to the stop. Re-tighten the
screw (e.g. with a coin) and check
whether the needle has been inserted
correctly by turning the hand wheel.
3 Needle stop
4 Needle channel
5 Screw
6 Flat side of the needle
Note
Do not tighten the screw too much as it may
be damaged and can then only be loosened
forcibly.
Caution
If the needle has been inserted incorrectly or
if the screw has not been tightened properly,
the needle may break or the machine may be
damaged. This poses a risk of injury.

Winding the lower thread
1 Spool on the spool pin
2 CB bobbin

4 Bobbin winder spindle
5 Winding tension disc
Only use the CB
bobbins recommended for this
machine by the manufacturer. The use of other
bobbins may lead to damage to the machine.
1 Pull out the spool pin and mount the spool.
2
Guide the thread to the CB bobbin over the
winding tension disc (5). Thread the end of the
thread through the hole of the CB bobbin from
the inside.
3
Put the CB bobbin on the bobbin winder
spindle. Push the bobbin winder spindle with
the bobbin to the right against the bobbin
winder stopper.
4 Turn the CB bobbin clockwise by hand until the
shaft sp
ring (6) clicks into the slot (7) of the
bobbin.
5 Connect the sewing machine to the mains and
switch on the power switch.
6 Pull out the hand wheel (8).
7 Hold the end of the thread and press the foot
controller lightly to wind the thread around the
bobbin several times.
8
Stop this process and cut the excess thread
(9).
9 Make sure that the thread is tensioned. If it is
too loose, it can wind around the bobbin winder
spindle. P
ress the foot controller until the
bobbin is full and the winding process stops
automatically.
10 Push the full bobbin winder to the left, cut the
thread (10) and remove the bobbin.

Removing the bobbin
Attention!
Errors when winding the thread on the bobbin
or when inserting it into the bobbin case affect
the thread tension.
A thread tension that is too loose or too tight
may result in faulty or skipped stitches!
1 Turn the hand wheel and move the
needle to the highest position.
2 Raise the presser foot lifter.
3
Switch off the machine at the power
switch.
4 Remove the extension table to the side.
5 Open the hook cover by swinging it
downwards.
6 Slightly pull the bobbin case bar tack (9)
forward and remove the bobbin case.
Important:
For further information about leading out the
lower thread see chapters

Inserting the bobbin
1 Insert the bobbin into the bobbin case;
in doing this, please
observe the
unwinding direction of the thread.
2 Insert the thread into the slot (4) of the
bobbin case und pull it below the
tension spring (5) in the direction of the
outlet opening (6).
Pull approx. 80 mm of thread out of the
bobbin case.
Important:
Make sure that the bobbin is inserted
in such
a way that the thread is
unwound in the right direction.
Unwinding the thread in the wrong
direction results in faulty or skipped
stitches.
3 Inserting the bobbin case
Place the bobbin case onto the shaft in
the hook and push it inwards until the
bar tack engages. When doing so, the
bobbin case finger must slide into the
opening in the ring cover.
Note:
Make sure to check that the bobbin
case has been inserted correctly.
Otherwise, it will fall out of the hook
when sewing.

Threading the upper thread
Caution: Switch off the power switch!
Note
There are digits on the sewing machine indicating the order (1 – 4) in which the upper thread has to pass
through. Always make sure that the thread is threaded correctly!
1 Lift the presser foot with the presser foot lifter.
Attention: The upper thread cannot be threaded correctly and the upper thread tension assembly will
be damaged if the presser foot is not lifted.
2 Turn the hand wheel (anti-clockwise) until the thread lever is in the highest position.
3 Pull out the spool pin and put on a spool.
4 Keep the thread tensioned by holding it with your right hand. Guide the thread through the thread
guide according to the digits.
Note
• An incorrect thread guide may result in tearing of the thread, skipped stitches or untidy seams.

Needle threader
1 Move
the needle to the highest position by
turning the hand wheel. Pull the needle
threader lever down as far as possible in the
direction of arrow.
2 Swivel the threader with the hook through the
eye of the needle.
Then, guide the thread below the right and left
guide hooks and pull the thread tight.
The thread must now be positioned below the
hook.
3 Swivel the threader as shown in the figure.
The hook now pulls the thread through the eye
of the needle.
* The threader can be used with needles of size
11 to 16. A thread weight between 50 and 90
is recommended.
