Changing The Fulcrum On The Presser Foot - Pegasus M900 Serie Instrucciones Para El Manejo

Changing the fulcrum on the presser foot

CAUTION
Always turn off the power, unplug the machine and then only
authorized technicians are allowed to change the fulcrum on the
presser foot.
There are two installation positions available for the shaft for the
presser arm (the fulcrum on the presser foot can be changed), the
upper and lower installation positions. The factory-set installation
position varies according to each subclass.
The upper installation position for the presser foot shaft provides
better feeding efficiency, so it is suitable for sewing knit fabrics.
The lower installation position for the presser foot shaft is effective
for the prevention of fabric puckering, so it is suitable for sewing
woven fabrics.
To change the fulcrum on the presser foot, another optional shaft
that is not supplied with the machine is needed. Please purchase
the optional shaft separately.
Fig. 27 illustrates how to place the presser foot shaft in the
upper installation position. Fig. 28 illustrates how to place the
presser foot shaft in the lower installation position. To change the
installation position, refer to either of these illustrations (Figs. 27
and 28). Parts other than the presser foot shaft can be removed
and then used again without any change in order to change the
installation position.
