9. The timing of the hook in relation to the needle
Check
- Set a new needle 90 into the machine
- Dismount the stitch plate, bobbin case holder and the bobbin case.
- Set machine on straight stitching.
- As the needle is moving upwards, the tip of the hook should pass
   behind the centre of the needle, when the needle is 2.5 mm above
   its lower turning position.
NOTE! Before any adjustment is done check that the setting
 2. Setting the hook in relation to the feeding eccentric is correct (see page 17).
Check with setting gauge 411 17 52-01.
1. Turn the handwheel until the needle is at its lower turning position.
2. Place the setting gauge on the needle bar so that the springloaded
     stud (A) just touches the needle bar frame and tighten the screw.
3. Move the needle upwards with the handwheel until the springloaded
    stud (A) rests against its stop in the setting gauge.
4. The tip of the hook should now be behind the centre line of the needle.
Adjustment
1. Remove the blank pointed screw (B) and loosen the other 2 screws
    in the belt wheel of the arm shaft.
2. Repeat checking points 1, 2 and 3 with setting gauge 411 17 52-01 .
3. Hold the arm shaft and turn the hook until its tip arrives behind
    the centre line of the needle.
4. Tighten one of the black screws.
5. Make sure the screw descends into the groove of the shaft so that the
    belt wheel is placed correctly sideways.
6. Check.
7. Tighten all the screws.

10. The needle height
Check
1. Bring the needle into its lower turning position.
2. The gap between the upper end of the needle and the surface (B)
     of the hook ring should be 29.15 ± 0.2 mm.
The check is executed with a polished needle 90 which is 29.15 mm long.
Order nr. 412 35 29 - 01
Adjustment
1. Bring the needle to its lower turning position.
2. Loosen screw (A) and move the needle bar until the correct
    measure is obtained.
3. Tighten the screw.
NOTE! Check by means of a twin needle that the needle bar is not
   twisted. May cause jump stitches when sewing with a twin needle.
