Operation
Operating manual 969 - 00.0 - 08/2014
ATTENTION
The auxiliary spring greatly increases pressure depending
on material thickness. This can cause defects when sew-
ing soft material or sewing over thicker areas in the mate-
rial.
If an auxiliary spring is not absolutely necessary due to the
presser foot rising when the needle moves up, do not use one.
5. Insert auxiliary spring (3).
6. Screw in adjusting screw (1) and adjust the presser foot pres-
sure.
7. Tighten the counternut (2).
ATTENTION
The use of the auxiliary spring in conjunction with maxi-
mum machine speed can damage the machine.
Limit the maximum machine speed when using the auxiliary
spring.
Reducing pressure:
1. Release the counternut (2).
2. Turn adjusting wheel (1) to the left until the desired pressure
is reached.
ATTENTION
Unscrewing the adjusting wheel too far will damage the
machine.
A slot on this screw indicates the maximum distance that the
adjusting wheel may be unscrewed. This slot must never be
higher than the upper edge of the counternut (2).
3. Tighten the counternut (2).
