Adjusting the thread regulator
Fig. 3: Adjusting the thread regulator
The thread regulator (3) controls the quantity of needle thread required for
stitch formation. The thread regulator must be precisely adjusted for an
optimum result.
With correct setting the needle-thread loop must slide with low tension
over the thickest point of the hook.
1. Release the screw (1).
2. Adjusting the position of the thread regulator (3).
Thread regulator to the left = more needle thread
Thread regulator to the right = less needle thread
3. Tighten screw (1).
Adjustment information:
If the maximum amount of thread is required, the thread tension spring (2)
must be pulled downwards approximately 0.5 mm from its upper end po-
sition. This is the case if the needle thread loop passes the maximum hook
diameter.
Risk of injury due to the needle tip and moving
parts
Only thread the needle thread while the automatic
sewing machine is switched off.
