Sewing Machine Review/Tips

• The seam allowance guidelines are found

on the stitch plate.

• The feed dogs move the fabric while you

are stitching. If you drop the feed dogs,

the fabric will not move by itself.

• The presser foot holds the fabric firmly in

place against the feed dogs.

• The thread tension controls the tightness

or looseness of the thread.

• The presser foot lever raises or lowers the presser foot. It must be lowered onto your fabric before you begin to sew. It is found on the back of your machine.

• The thread take-up lever pulls the thread from the spool pin. It must be at its highest point before you begin to sew or your machine will come unthreaded.

Thread Take-Up

Lever at Its

Highest Point

• The handwheel on the sewing machine

should always be turned TOWARD you to

raise and lower the needle. It will turn

away from you only when you backstitch.

• The bobbin case holds the bobbin. It

looks like this:

Remember, this is what a bobbin looks like:

Resolving Sewing Machine

Malfunctions

• Check whether:

– The upper and lower thread are correctly

threaded.

– The needle has been inserted correctly with

the flat side of the shank to the rear.

• If the upper thread breaks:

– The needle is blunt (not sharp).

– The upper thread tension is too tight.

If the sewing machine does not sew properly, it is usually due to incorrect use.

BEFORE you ask for help, check the following:

• If the lower thread breaks:– The lower thread tension is too tight.

– The bobbin is jammed.

– The needle is blunt or bent.

• If you have skipped stitches:– The needle is blunt, bent or incorrectly

inserted.

– A different needle is needed.

• If your needle breaks:– The needle clamp screw is not tight enough.

– The thread being used is of poor quality.

– The fabric is being pulled while needle is still inserted.

• If your machine fails to run:

– The plug is not inserted correctly.

– The power is not on.

– The bobbin winder is engaged.

– The handwheel is loose.
