Changing the maximum feed amount
If the feed dog has been replaced by one that does not match the feed amount that is currently being used, the
feed dog may touch the needle plate if the stitch length dial or condense dial are mistakenly set to settings that are
larger than the maximum feed amount for the feed dog, and this could cause problems such as damage or noise.
In order to prevent dial setting errors such as this, change the maximum feed amount setting for the sewing
machine to match the maximum feed amount for the feed dog.
1
Tilt back the machine head.
2
Loosen the two screws (1) so that the quick

3
Loosen the screws (3) and (4).
4
Move the stopper (5) down as far as possible, and
move the stopper (6) up as far as possible.
5
Turn the stitch length dial (7) and the condense
dial (8) to the maximum feed amount for the feed
dog being used.
Set the condense dial (8) to a negative number.
6
Check that the feed dog does not touch the needle
plate both when the reverse lever (9) is not
lowered and when it is lowered.
If it touches, adjust the forward/back installation
position (centering) of the feed dog.
