TROUBLESHOOTING PROBLEMS
PROBLEM CAUSE SOLUTION
Needle Breaks
NOTE: Whenever you
break a needle, make
sure you find all parts of
it before you continue
sewing. A needle point
that gets lodged in the
hook assembly of the
machine can cause the
machine to bind up and
stop running, possibly
causing serious damage.
Also check for burrs on
the hook if parts of the
needle are found under
the throat plate.
Needle inserted improperly Make sure the needle is inserted
all the way into the needle bar
shaft and the long groove is in the
front. Make sure the needle clamp
screw is tight.
Flow of thread is obstructed Check the top tension by pulling
the thread through the eye of the
needle. If it is excessively tight,
check all threading points to make
sure thread is not caught any-
where.
Needle too close to hook Hook needs to be re-timed.
Needle hits hoop Make sure hoop is big enough for
work being done.
Needle is bent Replace needle.
