Proper needle to hook relationship is important to prevent skipping of stitches if needle is too far
from the hook, and hook or needle damage if the needle is too close to the hook.
NOTE! Always use a new needle for checking and adjusting
Check
1. Set the machine on straight stitching
2. Remove the needle plate, the bobbin and the bobbin case.
3. Check the hook point. If the point is bent or burred - replace the hook.
4. Rotate hand wheel until the tip of the hook arrives behind the needle.
5. Check the gap by pressing a small screw driver against the needle.
The gap should be as small as possible, but max 0.15 mm.
Adjustment

NOTE! When the two screws (a) is loosened up the needle in center position can change.
2. Move the pivot (b), located on top of the needle bar, to the front or to the back until distance
between the point of the hook and the needle is correct.
3. Tighten securey the two screws (a).
4. Recheck and readjust if necessary.
