13 Broken
needles
Is the material being pushed or pulled with excessive force during
sewing?
Is the needle properly installed?
If it is incorrect, install the needle correctly.
Is the needle bent, is the needle tip broken, or is the needle hole
blocked?
Replace the needle.
Is the needle and rotary hook timing correct?
Adjust the height of the needle bar.
Adjust the clearance between the needle and the tip of the
rotary hook.
Is the needle timing too advanced with respect to the feed dog?
Retard the needle timing.
It is extremely dangerous to leave any pieces of broken
needle sticking in the material. If the needle breaks, search
for all pieces until the whole of the needle is found again.
Furthermore, we recommend that through steps be taken to
account for such needles to comply with product liability
regulations.

in turn cause the reset function to activate and stop the
machine, even if the power supply itself is normal.)
