3. Remove needle plates and bobbin cases
from all the heads.
4. Lower the needle holder by pressing down
with fingers on Fig. 4.

driver in direction shown with arrow mark on
Fig. 5 and set the angle of the adjustment
disk as shown in fig. 6.
6. Check the needle depth on all needles.
Pull white plastic ø17 measuring gauge in
and out of rotary hook in fig. 7. If height
gauge brushes lightly against tip of needle,
needle height is correct. If not, loosen

tighten after adjustment.
(Remove the gauge when finished).
Note: Height gauge is contained in tool box.
7. Turn main shaft slightly in direction shown
by the arrow mark.
Then set the angle of adjustment disc as
shown in Fig. 8.
Note the space or timing between needle
and tip of rotary hook as shown Fig. 9, 10.
If the space is too open or too close, loosen
3 screws of shuttle to adjust. Make sure to
tighten 3 screws after adjusted the space.
(The timing is set exactly at the factory.
However, in some cases timing is inadvert-
ently thrown off from handling during ship-
ment.)
