Presser bar lifter position
The clearance between the presser foot and the surface of the needle plate should be 5.7 to 6.3 mm when the presser
foot is raised.
The presser foot (zigzag foot A) should be pararell to the slot of the feed dog teeth when attached.
To adjust:
1. Turn the power switch off.
Attach the zigzag foot (A).
2. Turn the drop feed lever to lower the feed dogs.
3. Raise the presser foot with the presser foot lifter.
* You must use the presser foot lifter to raise the
presser foot for this adjustment, otherwise you
cannot adjust the presser foot height correctly.
4. Open the face cover. Loosen the setscrew on the
presser bar suporter to adjust the presser foot
direction as illustrated in Fig. 2 so the slot for the feed
dog teeth and the zigzag foot should be pararell.
5. Place the 6 mm spacer (block) between the presser
foot and the needle plate. Tighten the setscrew while
depressing the foot against the spacer.
6. Check "Embroidery foot height" (see page 27).
Check "Embroidery foot detecting sensor" (see page
28).
