Adjusting The Position Of The Feed Dog - Brother T-8421D Instruction Manual

Adjusting the position of the feed dog

Adjusting the forward/back position of the feed dog
Carry out this adjustment if the needle and the needle
hole in the feed dog are not positioned correctly even
though the clearance between the needle bar and the
presser bar (13.3 to 13.7 mm) is correct.
1
Loosen the two screws (1).
2
Turn the feed rocker base arm (3) to adjust so that
the needle drops into the middle of the needle hole
in the feed dog (2).
The needle will actually be slightly to the front
when it goes into the feed dog (2), and will be
slightly to the back when it comes out.
3
Tighten the screw (1).
CAUTION
Do not overtighten the screw (1). Otherwise it will
damage the feed rocker base arm (3).
Adjusting the left-right position of the feed dog
Adjust so that neither side of the feed dog touches the
needle plate (4) when the needle plate (4) is secured to
the bed with the screws (5) and (6).
If the needle plate and the feed dog are touching, loosen
the screw (1) and move the feed rocker base arm (3)
sideways to adjust.
