The standard angle for the feed dog (1) when it is at its
highest position above the needle plate is when the " "
mark (or V groove) on the shaft (2) is aligned with the feed
rocker bracket arm (3) and the feed dog (1) is parallel to
the needle plate.
1. Turn the machine pulley to move the feed dog (1) to its
highest position above the needle plate.
2. Tilt back the machine head.
3. Loosen the two set screws (4).
4. Turn the shaft (2) in the direction of the arrow within a
range of 90° with respect to the standard position. (Fig.
[C])
* In order to prevent puckering, lower the front of the
feed dog (1).
* In order to prevent the material from slipping, raise
the front of the feed dog (1).
5. Securely tighten the set screws (4).
* If you would like to tilt the feed dog (1) further, turn the
feed lifting rock bracket stud (5) while carrying out the
above adjustment. (Figure [D])
(Refer to "7-4. Adjusting the feed dog height" on the
previous page for details of this operation.)
* The height of the feed dog (1) will change after the
angle has been adjusted, so it will be necessary to re-
adjust the height of the feed dog (1).
