Adjusting The Feed-Dog - Bernina KL. 940 Service Manual

CASE RETAINER
Following adjustment of needle and hook, the case retainer 1 1 6 for the bobbin case
holder 104 should be secured on the machine and moved forwards until the lower edge of
the bobbin case retainer intercepts the bobbin case holder lug on both sides.
In addition, it must be ensured that the holder finger in the bobbin case stopper fork has
0.6 mm clearance for the passage of thread.
If this is not the case, the left wing 120 of the bobbin case stopper fork can be moved
upwards or downwards as necessary.
