Presser Foot J
This foot is used for overcasting, seam
and overcasting, i.e. stitches which have
a stitch width of 5.0 and 5.5 mm. Stitches
form over the pin which prevents
puckering at the edge of the fabric.
Sensor Buttonhole Foot
When connected to the machine it
measures buttonhole length and sews
the buttonhole size that has been entered
into the machine. The middle mark gives
a 9/16'' (15 mm) buttoning edge.
Read more about different optional
presser feet in the Accessory User’s Guide.
Changing the Presser Foot
Switch off the main switch.
1. Make sure that the needle is in the
highest position. Pull the presser
foot towards you.
2. Line up the cross pin on the foot
between the spring and the presser

snaps into place.
Presser Foot Pressure (a)
The presser foot pressure is adjusted
with the dial found under the lid on
your Platinum 770. Normal setting is
around four. The higher the number the
more pressure on the fabric. Knit and
soft fabrics should be sewn at lower
pressure.
Presser Foot Lever (b)
The presser foot is raised and lowered
with the presser foot lever. The presser
foot must be lowered when sewing.
By raising the presser foot lever as
far as it goes and press it upwards, the
lift height of the presser foot can be
increased by several millimeters.
