The excess fabric is trimmed and the hem is sewn and the
raw edges are overlocked in one operation.
The overlock blind hem is best suited for sewing knit wear.
It provides a durable finish that is almost invisible.
Use overedge right needle and adjust machine for a narrow
3-thread overlock stitch. (See page 43)
Note: The three-thread flatlock stitch can also be used.(See page 44)
Set the stitch length dial at 4
Fold the hem to the wrong side of the fabric, then back to
the right side with 6 mm (1/4 inch) beyond the fold.
Stitch on the extended hem edge, allowing the machine
needle to barely catch the edge of the fold.
Note: An optional blindstitch foot is available. (See page 68)
Sew decorative pin tucks on the fabric before cutting
out the garment.
Use overedge right needle and adjust machine for a
narrow 3-thread overlock stitch. (See page 43)

An overlock machine requires more maintenance than a
conventional machine for two reasons:
1) A lot of lint is produced due to the cutting action
of the knives.
2) An overlock runs at a very high speed and needs
to be oiled frequently to lubricate the internal
working parts.
Clean the lint from the looper and knife area often
with a dry lint brush.
Before cleaning your machine, disconnect
power line plug from the wall receptacle.
The oiling points shown in the diagram, should be
oiled periodically.
Note: Use only sewing machine oil. Do not use any other oil or damage could result.
Before lubricating your machine, disconnect
power line plug from the wall receptacle.
