2. Set the dial
for setting the amount of alternating vertical move-
ment of the walking foot and presser foot to [1] on the scale.
3. Remove the rubber plug from the top cover.
4. Loosen the upper feed cam clamping screw
from the hole where
the rubber plug has been removed.
5. Align the marker dot
engraved on the top feed arm with the gradu-
ation [L] on the hand-wheel.

o Improper stitch length may result
when the machine is operated at
high/low speed.
o The lifting amount of the presser
foot or the walking foot would be
decreased. As a result, the ma-
terial may not be fed smoothly.
5’ If the graduations on the hand-
wheel shift in the direction A from
the marker dot
, the lifting
amount of the walking foot will
decrease and the lifting amount
of the presser foot will increase.
If the graduations on the hand-
wheel shift in the direction B, the
former will increase and the lat-
ter will decrease.
