1. Apply appropriate grease to the groove section of the feed adjusting
screw and mount the O ring in the groove section.
2. Adjust the feed dial and the feed adjusting screw , and
temporarily join them with the feed dial screw .
3. Set the feed dial stopper washer C on the arm side and attach
the feed dial stopper and its washer A to the feed dial stopper pins
and that have been driven into the frame. Then, pinch them
with the feed dial stopper washer B.
Position of the feed dial stopper washer A is determined by
changing the joint between the recess of the feed dial stopper washer
A and the feed dial stopper pin so that the clearance A becomes
0.5 to 5mm between the feed dial stopper and the feed dial pin
when the feed lever is pushed down.
4. Enter the feed dial pin spring and the feed dial pin in the arm.
5. Attach the feed dial washer and the feed dial spring to the
shaft section of the joined feed dial . Enter the assembly in the
arm.
6. In the state that the feed dial graduation 0 coincides with the engraved
marker dot of the arm, join the feed dial screw with the feed
adjust screw .
(Cautions) After joining, confirm that the engraved marker dot of
the arm coincides with the feed dial graduation 0.
o If there is no clearance of A when
the feed lever is pushed down,
there is no effect of fixing the feed
dial .
o If the clearance of A is too much
when the feed lever is pushed
down, the feed lever will be
returned unexpectedly while the
sewing machine is operated.
o If there is any displacement be-
tween the arm’s engraved marker
dot and the feed dial graduation,
there is no coincidence between the
dial graduation value and the pitch.
