Adjustment Of Needle Bar Height - ELNA Supermatic Service Manual

7. Adjustment of Needle Bar Height

The needle bar height is correctly adjusted when the point of the shuttle hook just touches the lower end of the
gauge No. 607800 while passing below this gauge. If this is not the case, adjust as follows:
Remove needle, presser foot and needle plate, then insert needle bar height gauge No. 607800.
Stitch width knob at "0."
Set Centering Dial at Center Position.
Turn flywheel towards you and check whether point of shuttle hook just
touches gently the flat at the bottom of the gauge.
If needle bar is set too high, proceed as follows:
Lower presser foot lever to open front cover. (Thread take‐up lever must be
in a raised position.)
Turn flywheel slowly towards you until point of shuttle hook is just below the
needle bar height gauge.
Loosen screw in needle bar link pin and lower the needle bar until gauge
rests upon point of shuttle hook.
Tighten screw in needle bar link pin after this adjustment.
If needle bar is set too low, follow the same procedure as above, but after
loosening the screw in the needle bar link pin, raise the needle bar above the
shuttle hook to begin.
Remove gauge and close front cover. Replace needle plate, presser foot and needle.
It is essential after the above adjustment to check also the clearance between needles and point of shuttle hook
when using the double needle clamp (to prevent skip stitching and needle breaking).
