Operation
4.5.2 Winding the hook thread
The hook thread is normally wound on when sewing is in progress.
However, you can also wind on the hook thread without sewing,
e. g. if you require a full bobbin in order to start sewing.
NOTICE
Property damage may occur!
Damage to the sewing feet or throat plate possible if the
thread is wound on without sewing material.
Lock the sewing feet in place at the highest position and set
the sewing foot stroke to the smallest value if you wind on
hook thread without sewing material.
To wind the hook thread:
1. Switch on the machine.
2. Press the pedal forwards.
The machine sews and winds the hook thread from the
thread reel onto the bobbin.
When the bobbin is full, the machine automatically stops
winding. The bobbin lever moves down.
The cutter is automatically moved into its basic vertical
position.
3. Pull off the full bobbin.
4. Tear off the thread behind the cutter.
5. Insert the full bobbin into the hook ( p. 31).
6. Repeat the winding procedure with an empty bobbin, as
described above.

4.6 Replacing the hook thread bobbin
WARNING
Risk of injury from sharp parts!
Punctures possible.
Switch off the machine before replacing the hook
thread bobbin.

To change the hook thread bobbin:
1. Push up the bobbin case retainer (6).
2. Remove the empty bobbin.
3. Insert a full bobbin.
Important
Insert the bobbin so that it moves in the opposite direction of the
hook when the thread is pulled out.
4. Feed the hook thread through the slot (4) in the bobbin case.
5. Pull the hook thread under the tensioning spring (3).

6. Feed the hook thread through the slot (1) and pull it approx.
3 cm further.
7. Close the bobbin case retainer (6).
4.7 Thread tension
Together with the hook thread tension, the needle thread tension
influences the final seam pattern. With thin sewing material, excessive thread tension can lead to undesired gathering and thread
breakage.
Proper setting
If the tension of needle thread and hook thread is identical, the
thread interlacing lies in the middle of the sewing material.
Set the needle thread tension so that the desired seam pattern is
achieved with the lowest possible te nsi o n.

Main tensioner
Proper setting
The main tensioner (2) determines the normal tension during
sewing.
Set the main tension as low as possible.
Fault due to excessively high needle tension
• Ruffling on the seam
• Thread breaking
To set the main tensioner:
1. Turn the adjusting wheels (2).
• Increase the needle thread tension: Turn the adjusting
wheels (2) clockwise
• Reduce the needle thread tension: Turn the adjusting
wheels (2) counterclockwise

Operation
Pre-tensioner
The pre-tensioner (1) holds the thread in position if main
tensioner (3) and additional tensioner (2) are open completely.
The pre-tensioner (1) also determines the length of the initial
thread for the new seam.
To set the pre-tensioner:
1. Turn the adjusting wheel (1).
• Short initial thread: Turn the adjusting wheel (1) clockwise
• Longer initial thread: Turn the adjusting wheel (1) counterclockwise

To lock the sewing feet at top dead center:
1. Push the lever on the rear of the machine up or down.
• Locking the sewing feet at top dead center: Push the lever
down (1)
• Canceling the lock of the sewing feet: Push the lever up (2)
You can also use the pedal to cancel the upper position:
1. Press the pedal halfway back.
The lever swivels back up, and the lock is canceled.
4.9.3 Setting the sewing foot pressure
The adjusting wheel at the top left of the machine arm determines
the contact pressure the sewing foot exerts on the sewing material.
The pressure can be adjusted continuously by turning the adjusting wheel.
The correct pressure depends on the sewing material:
• Lower pressure for soft materials, e.g. cloth
• Higher pressure for hard materials, e.g. leather
Proper setting
The sewing material does not slip and is correctly transported.
Disturbance from incorrectly set sewing foot pressure
• Excessively high pressure: Tearing of the sewing material
• Excessively low pressure: Slipping of the sewing material
