Lowering Of The Feed Dog - Husqvarna 6690 Manual

The ratio between the setting
of the feed dog and the needle
(the after-feed).
Press the button for straight stitching and the
button for stitch length until 6,0 is indicated.
Insert a piece of paper under the presser foot
and turn the handwheel until the thread take-up
lever is at the highest position. Mark the paper
in the needle hole of the presser foot. Turn the
handwheel anti-clockwise until the machine has
finished feeding and make a new mark on the
paper in the needle hole of the presser foot. The
distance between the marks should be 0.3-0.6
mm. This means that the machine has fed 0.3-0.6
mm after the thread take-up lever has reached
the highest position. This movement of the feed
dog is usually called "the after-feed".
Adjustment
Loosen the screw (7/8) on the counter-weight of
the stitch length eccentric, and hold it fixed. If the
after-feed is insufficient turn the arm shaft in the
working direction. Then tighten the screw (7/8).
The feed dip
Requirements
The machine should sound normal when the feed
dog is in the feeding position and when dropped.
Action
Remove the cover (5/13) under the base plate.
While the machine is running turn the setting
screw for the feed dog support (10/28) clockwise
until the sound changes.
Then turn the screw backwards approx. 1 turn, or
until the machine is running at its normal sound.
