HOW TO ADJUST THE STITCH
LENGTH
HOW TO ADJUST THE SEAM
WIDTH
Cutting width dial
Stitch lenght dial
– The stitch length dial should be set on the "• =
2.5" setting for most sewing conditions.
– Adjust the stitch length to 2.5 – 4 when sewing
heavy weight fabrics.
– For rolled hems and narrow seams set the
stitch length between 1 and 2.
– A shorter stitch length can be used to avoide
fabric from puckering.
– Adjust the stitch length to 2 – 4 when sewing
highly stretchy fabrics.
Overlock seam width can be achieved by repositioning
the needle position and also with the cutting width dial.
Width adjustment by changing
needle position
Overlock seam width can be adjusted by changing the
needle position.
