The needle guard on the bobbin case holder, shown
in
Figs. 51 and 54, should prevent needle from con
tacting hook or bobbin case at any time. See Fig. 51
(A) for correct relationship. When large needles {size
20 or larger) are used, needle guard may deflect needle
too far toward left resulting in damage to needle. See
Fig. 51 (B). To avoid this, it may be necessary to
string the needle guard in accordance with the follow
ing instructions.
MACHINE 281-5: Remove bed-raising plate.
ALL MACHINES: Remove needle, slide plate, throat
plate and bobbin case from machine
Turn machine pulley until feed bar, Fig. 52, is at
its highest point.
Remove position finger shown in Fig. 52.
Turn hook body to position shown in Fig. 52 and
remove three small screws and hook section shown.
Turn bobbin case holder until position finger slot
on thread guard is at location shown in Fig. 53. Slip
bobbin case holder out of hook body.
Remove a
slight amount of metal from needle guard
by rubbing needle guard along a 1/8 inch strip of very
fine emery cloth, as shown in Fig. 54.
EXTREME CARE should be taken to avoid removal
of too much metal as this may permit needle to strike
hook. See Fig. 51 (C). Bobbin case holder will then
need replacement.

case holder thoroughly before re
placing it in hook body.

removal.
