SKIPPED STITCHES

A bent or blunt pointed needle is often the cause of this. See that the needle

plate is accurately inserted, (see page 8) Remove the needle plate and after

ascertaining that the feed is clean and working freely, replace the needle plate. ^

NEEDLE BREAKS

See that the needle is not bent and avoid pulling the material when stitching ;

either condition will cause the needle to strike on the needle plate and break.

MATERIAL PUCKERS

This is generally due to incorrect tension. See that both the bobbin case and

the needle are properly threaded : that the thread used is of good quality and the

correct size for the needle, (see page 23)

STITCHES LOOP

This is regulated by the tensions, (see page 11) See that both the bobbin case

and the needle are properly threaded ; that the thread used is of good quality

and the correct size for the needle, (see page 23)
