Adjusting The Stitch.
The Strongarm Sewing machine stitches both straight and zig zag, with stitches up to 6mm long
and zig zag up to 4 mm wide.
To adjust stitch length, lift the stitch length lever up and
down. All the way up is 6mm.
½ the way up is 0mm and
reverse is all the way down.
Setting The Tension.
Your Strongarm Sewing machine is factory pre-set to an
average tension that should work on most canvas
applications. A little tension adjustment goes a long way, so
only make small adjustments at a time.
As a general rule, the thicker the fabric, the higher the tension must be to lift the lower thread up
to the middle of the layers of fabric and meet the top thread. Thick upholstery fabrics for example
may require a higher tension setting and a longer stitch length and lighter fabrics may require a
lower tension setting.
The zig zag lever adjusts the width of the stitch. All the way to
the right is 0, or straight stitch, and all the way to the left is
4mm. Make sure the needle is out of the fabric when
adjusting needle width as this could bend the needle.
When set to straight stitch, the needle position lever sets the
needle to a left, right and centered position. This is useful
when sewing very close to features such as zippers. Push the
lever down slightly in order to change position.
Make sure the needle is clear of the fabric when adjusting the
needle position as this operation could bend the needle.
