TO SET NEEDLE
Raise the lieedle-bar to its highest point; loosen the thumb-screw
and press it to the left to permit the shank of the
needle
to pass up
between the clamp and needle-bar as far a sit will go, flat side to the
RIGHT—the NEEDLE being flatened on one side so it will set itself per­
fectly, then fasten securely by tightening thumb-screw.
To avoid loosening of the needle, ahoays use a screw driver to
fasten the same, the needle nut bemg slotted for that purpose.
The needle, when descending, should pass
central
in the needle
hole from
front to rear , but close to the right side of the hole, as it
prevents the needle from glancing into the race and being caught by
the shuttle.
NEEDLES AND THREAD TO BE USED
The
MOST IMPORTANT
consideration is to buy and use perfect nee­
dles—not bent, nor blunt points.
When ordering needles for this machine, be sure to ask for the
genuine White Rotary flat shank needles which are stamped on the
shank “White F. R.” Imitation or “just as good” needles will cause
trouble. Get the genuine White.
