4. Remove the old needle by pulling it down. Discard the old needle in a safe way.
5. With the scarf of the needle
(indentation at the back of the
needle just above the needle eye)
facing the rear of the machine and
the long groove down the front of
the needle facing the front of the
machine, push the needle all the
way up into the needle bar until it
stops. Check the sight hole in the
needle clamp to verify that the top
of the needle can go no farther up.
U
CAUTION
: Check the needle to confirm it is fully inserted. The needle bar has a sight
opening above the needle bar clamp screw. Make sure the needle is touching the top
of the sight opening. If it isn’t, the machine timing will be off and it may be possible for
the needle to collide with internal parts, causing damage not covered by warranty.
6. Carefully tighten the needle bar clamp screw.
U
CAUTION
: Although you can use your fingers to tighten the needle bar clamp screw, we
recommend that after finger-tightening the screw, you use the 2.5mm hex wrench to
tighten it just a bit more. The QMP20 Versa ST runs at very high speeds and this ensures
the needle will not loosen while quilting. However, do not over tighten the needle clamp
screw, as this may strip the threads of the screw. Stripped threads are not covered
under the warranty. It may also become difficult to insert the needle properly into the
needle bar. Once the screw no longer turns freely by hand, gently turn the screwdriver
until the screw is tightened snuggly.

QUILTING TIP
: A size 16/100 needle will accommodate most threads and fabrics. Heavier
threads, such as top stitch and some decorative threads, require a larger needle such as
18/110 or 21/130. Lofty batts and heavier fabrics such as denim, canvas, or densely woven
fabric may also require a larger needle.
