Important notes on sewing with the cover
stitch
The power table is marked with various units
of measurement. The upper fi gures are in cm.
The lower fi gures are in inches.
Note: The hemmer guide H2 is available as
an optional accessory. With this optional
accessory you can hem your fabric
effortlessly without having to press under the
hem edge prior to sewing the cover stitch.
To start sewing:
Raise the presser foot and place the fabric
under the presser foot so the needles pierce
the fabric for the fi rst stitch. Position the
fabric at the desired width using the marked
guidelines on the power table. When starting
to sew, pull the fabric taut towards the rear
and sew slowly. The speed may be increased
as you sew further along the fabric.

Preparing the fabric:
When not using the H2 optional accessory
guide, it is useful to press under the fabric
edge before hemming it. The width of fabric
to be pressed under must be 0.5 cm wider
than the fi nished hem width. Example: Press
under a one inch (2.5 cm) fabric width to sew
a fi nished hem of 3/4 inch (2 cm).
Note: Set the seam width at 3.5 cm.
Finishing sewing:
1. When sewing to the end of the fabric:
Tightly hold the threads at the end of the
seam. Sew slowly off the fabric while lightly
pulling the threads toward the rear of the
machine.
Note: The differential feed may need to be
adjusted slightly to allow your fabric to lie
perfectly smooth. Test your settings fi rst on
a piece of scrap fabric.
