To prevent point of hook from dividing
strands of thread, it should pass as close
as possible to the needle (within the clear-
ance above needle eye).
Turn machine pulley over toward you
until point of sewing hook is at center of
needle. Loosen screws Nand T, Fig. 27,
underneath bed of machine and move hook
saddle to the right or left, as may be re-
quired, until point of hook is as close to
needle as possible without striking it, then
securely tighten screws Nand T.
CAUTION: Make sure hook driving gears
U, are set correctly with relation to face
of hook saddle. Use • 008 shim.
The function of hook washer (needle
guard) G2, Fig. 25, which is attached to
bottom of sewing hook, is to prevent point
of hook from striking needle if, when pass-
ing through mate rial, needle is deflected
toward hook.
The needle guard can be bent with a small
pair of pliers until it prevents hook point
from striking needle, but it should not be
bent outward enough to deflect needle from
its normal path.
