The table shows the configurable range of the machine's
parameters. The actual values for stitch co unt/min. or presser foot
stroke must be adjusted through a practical sewing test to suit the
properties of the material and thread. Improper parameter values
can be determined through increased noise or needle heating and
thread burn-out.

5.2 Inserting and replacing needle
WARNING
Risk of injury from needle and moving parts.
Turn the sewing machine off before replacing the
needle.
Do not touch the tip of the needle.
Order
After switching to a different needle size, adjust the distance
between the hook and the needle ( Service manual).
ATTENTION
Damage to the machine, needle breakage, or thread dam-
age is possible due to incorrect distance between the needle and hook tip.
Check the distance to the hook tip after inserting a new needle
with a different size. Reset distance if necessary.
Incorrectly setting the needle height can damage the
machine.
Checking needle height is absolutely necessary when changing the needle for another system.
Incorrectly setting the allowance for clearance be tween
needle and hook tip can result in the following defects:
After inserting a thinner needle:
• Missing stitches
• Thread damage
After inserting a thicker needle:
• Damage to the hook tip
• Damage to the needle

• Damage to the hook tip
• Damage to the needle
After inserting a longer needle:
• Damage to the hook tip
• Damage to the needle
ATTENTION
Incorrect alignment of the needle can damage the
machine.
Make sure the hook tip does not come into contact with the
needle.

1. Turn handwheel until the needle (3) is at top dead center.
2. Loosen the screws (2).
3. Pull the needle (3) down and out.
4. Insert the new needle.

5.3 Threading the needle
WARNING
Risk of injury from needle and moving parts.
Turn off the sewing machine before threading the
thread.
5.3.1 Threading thread in reel holder
ATTENTION
An incorrect tube height causes the thread to wind onto
the needle tube resulting in irregular needle thread tension. This can result in an uneven seam and uneven thread
lengths after cutting!
Check that the tube height is set correctly.
On all submodels, the thread is fed through the machine from a
reel on a reel holder.
