ADJUSTMENT OF SEWING HOOK HEIGHT
When lower timing mark on needle bar is just
visible at lower end of needle bar frame on upword
stroke of needle, the hook should pass about 1/16
inch above upper edge of needle eye as shown in
Fig. 27.
To adiust height of sewing hook, first fasten
throat plate to bed of machine and place bobbin case
stop finger in sewing position. Pass a .032 inch shim
between bobbin case stop finger and throat plate. If
shim is too tight or too loose, turn machine pulley
over toward you so that the hook hub socket screws
shown in Fig. 28 are accessible with a socket wrench.
Loosen both screws and remove cloth washer from
bobbin case. Turn bobbin case until one of the holes
is in line with hook height adjusting screw. To raise
hook, turn hook height adjusting screw downward. To
lower hook, turn hook height adjusting screw up. Re-
tighten socket screws and turn hook height adjusting
screw again just enough to leave a light tension.
Check sewing hook timing.
ADJUSTMENT OF DISTANCE BETWEEN SEWING
HOOK AND NEEDLE
To prevent hook point from dividing strands of
thread, it should pass as near to the needle as pos
sible without hitting it.
Turn machine pulley over toward you until sewing
hook point is in the position nearest to needle. Tip
machine
and loosen hook saddle screws shown in
Fig. 29. Adjust hook saddle until hook point is as
close to needle as possible without hitting it. Re-
tighten hook saddle screws BE SURE HOOK DRIVING
GEARS SHOWN IN FIG. 29 ARE CORRECTLY SET
WITH RELATION TO FACE OF HOOK SADDLE. USE
.008 INCH SHIM.
The function of the needle guard shown in Fig. 28
is to prevent hook point from striking needle, if needle
is deflected after penetrating material. The needle
guard can be bent with a pair of pliers, if necessary,
but care should be taken to prevent guard from inter
fering with normal path of needle.
