FEED DOG ALIGNMENT
1.
When the stitch length dial is
set to 0
(knob turned all the
way clockwise)
the feed dog
in the center slot should be
4.2
– 4.8mm from the front
edge of the slot opening of
the needle plate.
2.
The lateral gaps for the feed
dogs should also be even.
3. If you need to adjust the feed
dogs, lay the machine on it’s back
and locate the feed rock arm and
loosen the two hex set screws with
a 2.5mm hex tool.
*Use bottom part of gauge
QM39401 for center feed position.
4. Move the feed base arm up
or down to obtain the 4.2
–
4.5 center feed position.
5. Move the feed rock arm left or right
to obtain an even lateral gap for the
feed dogs. Retighten hex set screws.

Theory: the feed dogs should not interfere or
hit the needle plate no matter how long or short
the stitch length is set. Quick check: set the
stitch length at 6 and check in forward and
reverse with the reverse lever while running the
machine to make sure the feed dogs do not hit
at any point.
