Singer 20U - Needles and Thread; To Set the Needle

NEEDLES AND THREAD
This machine uses needle Catalog 1910-05, available
in sizes 9, 11, 14, 16 and 18.
The needle you use should be straight, with a sharp point,
to ensure perfect stitch formation and needle penetration through
the fabric. The needle should also be fine enough to prevent the
fabric from being marred with large punctures, yet heavy enough
to pierce the fabric without being bent or deflected. Remember,
too, that the eye of the needle must be large enough for the thread
to pass through it freely; too fine a needle will cause the thread to
fray.
Be sure to use like threads for both needle and bobbin.
TO SET THE NEEDLE
1. Raise needle bar to its highest position by turning hand wheel
toward you.
2. Loosen the needle clamp screw and insert needle into clamp
as far as it will go, with the long groove toward you. Then
tighten the needle clamp screw.
