To Adjust The Feed Dog Height - Janome FA4 Service Manual

TO ADJUST THE FEED DOG HEIGHT

Correct Setting:
When the presser foot is lowered and the feed dogs are at their highest position, the distance
between the surface of needle plate and bottom of presser foot should be 0.75 to 0.95 mm.
To adjust:
1. Remove the free arm cover unit and the back cover unit. (see page 5)
2. Set the stitch length dial at "3" and the differential feed dial at "1.0" .
3. Lower the presser foot and raise the feed dogs to their highest position by turning the handwheel.
4. Loosen the screws A, B and C.
5. Insert the screwdriver in the slit of the eccentric pin.
Adjust the main feed dog by turning the pin then tighten the setscrew A.
(The standard setting of the feed dog height is when the slit on the eccentric pin is horizontal and eccentric
position is at the rear side.)
6. Push the sub feed dog upward and adjust the distance between the surface of needle plate and bottom of
presser foot, then tighten the setscrews B and C.
7. Check the clearance between the feed dog and the slot of the needle plate when the stitch length is set at 5
and differential feed is set at maximum.
(If the direction of the eccentric adjustment is incorrect, the needle plate and feed dog may hit or rub each
other.)
8. Attach the free arm cover unit.
