8 Setting the stitch length limit

9 or 6 mm can be selected as the maximum stitch length. In doing so, the
appropriate throat plate has to be selected for the respective maximum
stitch length. The throat plate cut-out must be large enough that the feed­dog does not hit against the edges of the throat plate at the front and rear
dead center.

If during the sewing operation not all stitch le ngths are available, then you
do have the option to limit the maximum stitch length that can be set.

WARNING

Risk of injury.

Crushing injuries from moving parts.
Switch off the sewing machine before setting the

maximum stitch length limit.

ATTENTION

Risk of damaging the feed-dog due to incorrect throat plate size

If the throat plate cut-out is too small, then the feed-dog can hit against
the edges.

Make sure that an appropriate throat plate is used for the maximum
stitch length set.

Correct setting

Turn the stitch length adjusting wheel clockwise as far as it will go.
 The stitch length adjusting wheel can only be turned up to the maxi-

mum stitch length set.

9 Setting the feed-dog

The position and the movement of the feed-dog and need le bar have to be
coordinated such that the needle pierces exactly in the center of the nee­dle hole of the feed-dog.

9.1 Setting the feed-dog position

WARNING

Risk of injury.

Correct setting

The feed-dog is exactly in the center of the throat plate cut-out, both side­ways and in the sewing direction.

If the stitch length is 0, the needle pierces exactly in the center of the ne e­dle hole.

Various settings can be made depending on how far the position of the
feed-dog differs from the correct setting:

• For minimal deviations, it suffices to move the feed-dog on the carrier
( 9.1.1 Moving the feed-dog, page 28).

• If this is not sufficient, move the entire feed-dog carrier on the sliding

13.3 Setting presser foot pressure

The left adjusting wheel on the machine arm determines the pressure for
the sewing feet on the material to be sewn. The pressure can be adjusted
continuously by turning the adjusting wheel.

The correct pressure depends on the material to be sewn:

• Lower pressure for soft materials, e.g. silk

• Higher pressure for harder materials, e.g. leather

Correct setting

The material being sewn does not slip and is correctly transported.

Fig. 39: Setting presser foot pressure

Setting steps

1. Turn the adjusting wheel for the sewing foot pressure (1):

• Clockwise: more pressure

• Counter-clockwise: less pressure

13.4 Setting the sewing foot lifting height

WARNING

Risk of injury.

The sewing machine must remain switched on so
that the sewing feet can be raised.

Work very carefully when you check and set the lift­ing height for the sewing feet.

Do not put your hands under the sewing feet when
they are being lowered.

When the pedal is pressed back halfway, the sewing feet can be raised
during sewing, e.g. to move the material being sewn.

When the pedal is pressed completely back, the sewing feet will be raised
after the thread is cut so that the material being sewn can be exchanged.

14.1 Setting the thread regulator

The thread regulator determines the tension applied to guide the needle
thread around the hook. The required tension depends on the thickness of
the material to be sewn, thread strength, and stitch length.

Lower thread tension for

• thin material

• low thread strengths

Greater thread tension for

• thick material

• high thread strengths

WARNING

Risk of injury.

Risk of crushing injuries and stab wounds from mov­ing and sharp parts.

Switch off the sewing machine before checking and

the upper position of the thread lever up to the point when the needle eye
plunges into the material being sewn.

Correct setting
Basic setting: The thread tensioning spring does not contact the stop un-

til the needle eye has plunged into the material being sewn.
The setting for the thread tensioning spring must be varied according to

WARNING

Risk of injury.

Risk of crushing injuries and stab wounds from mov­ing and sharp parts.

Switch the sewing machine off before you check

clamp.

The shape of the thread-pulling knife automatically c reates the required cut­ting pressure as soon as the thread-pulling knife and counter-blade make
contact.

Correct setting

In the rest position, the hook thread clamp makes contact with the thread­pulling knife without any pressure being applied. Any 2 threads with the
greatest strength used for sewing can be neatly cut simultaneously.

• Increased knife wear when the pressure is too great

• Problems when sewing on if the hook thread clamp is too high

• Problems in cutting the thread
