11 Adjusting the needle thread tension
Information
Fig. 57: Adjusting the needle thread tension, spring balance
You can order a spring balance with thread hook from our sales offices
using the following part numbers: 0APP 001503.
11.1 Adjusting the needle thread regulator
The needle thread regulator determines the tension applied to guide
the needle thread around the hook. The required tension depends on
the thickness of the sewing material, thread strength, and stitch length.
• Lower needle thread tension: thin sewing material, low thread
strengths
• Higher needle thread tension: thick sewing material, high thread
strengths
Proper setting
The loop of the needle thread slides at low tension over the thickest point
of the hook, without forming loops or snagging.
CAUTION
Risk of injury from sharp and moving parts!
Puncture or crushing possible.
Switch off the machine before adjusting the needle
thread tension.
