Checking the Needle Condition
The needle condition should be checked and
the needle replaced regularly. A defective
needle not only damages the fabric but also
the sewing computer.
The following are the guidelines: replace
needle when starting a new sewing project or
as required.
Correct Needle/Thread
Combination
When sewing, the thread should travel
smoothly down the long groove on the front
of the needle.
Too Thin Thread or too Thick Needle
The thread has too much clearance in the
groove. Skipped stitches and damage to the
thread can occur.
Too Thick Thread or too Fine Needle
The thread rubs on the edges of the groove
and can get jammed. This can break the
thread.
