1. Raise the presser foot and set the stitch
length regulator to maximum (8mm). Turn the
balance wheel to lower the needle into the hole
of the feed dog and check to see if the needle
is centered in the hole at the feed dog’s forward
most position (
B
).
Note:
If the needle if not centered in the Feed
Dog hole (
B
), see page 45.
2. Keep turning the balance wheel until a
full rotation is achieved. If the needle is still
centered in the feed dog hole
(
B
)
throughout
the movement, then the mechanism is timed
properly. If it ends up in position (
C
), this
indicates that the feed amount of the needle bar
and presser foot is larger than that of the feed
dog. To correct this, you will need to reduce
distance (
D
)
.
Use a wrench and loosen the nut.
Slide the nut and its connected pivot block up.
If the timing is off and the needle ends up at
position (
E
), then the feed amount of the needle
bar and presser foot is smaller than that of the
feed dog. In this case, enlarge distance (
D
) as
explained above but slide the nut down. Make
adjustments until the needle arrives at (
B
)
(the
center of the feed dog hole at the end of the
rotation).
