Thread Tension
A
B
C
To set the thread tension, turn the dial on top of the machine.
Depending on the fabric, thread, etc, the tension may need to
be adjusted. For the best stitch appearance and durability,
make sure the needle thread tension is correctly adjusted. For
general sewing, the threads evenly meet between the two
layers of fabric (A).
If the bobbin thread is visible on the top side of the fabric, the
needle thread tension is too tight (B). Reduce the needle thread
tension.
If top thread is visible on the underside of the fabric, the
needle thread tension is too loose (C). Increase the needle
thread tension.
For decorative stitches and buttonholes, the top thread should
be visible on the underside of the fabric.
Make a few tests on a scrap piece of the fabric you are going to
sew and check the tension.
Sew without Feed Teeth
2 1
When sewing on buttons or doing other sewing techniques
where you don't want the fabric to feed, you need to lower the
feed teeth.
The feed teeth lever is found at the back of the free arm.
1. Lower the feed teeth by moving the lever to the “Feed
Teeth Down” position.
2. Raise the feed teeth by moving the lever to the “Feed Teeth
Up” position.
Note: The feed teeth will not raise immediately when the lever
is switched. Turn the hand wheel toward you one full turn or
start sewing to re-engage the feed teeth.
Presser Foot Pressure
3
The presser foot pressure is used to control the amount of
pressure that the presser foot exerts onto the fabric, to ensure
smooth feeding of the fabric while sewing. The presser foot
pressure has been pre-set to the standard value "2". Though it
needs no adjustment for most fabrics, it can be adjusted for
very thick or very thin fabric - increase for heavy weight
fabrics, decrease for lightweight fabrics.
Note: If the dial is turned counterclockwise too much, it could
come off. If this happens, simply replace the dial and turn it
clockwise until it stays in place.
Note: If the dial is turned clockwise until it comes to a stop, it
has reached the maximum pressure available. Do not try to
turn the dial any further!
