11.07.02 Thread catcher and knife height
Requirement
1. There should be a clearance of 0.6 mm between the lower edge of the thread catcher 1
and the bobbin case 2.
2. When the thread trimmer is in its resting position the upper edges of knife 3 and thread

The thread catcher and knife height is pre-set by the manufacturer and can only
be corrected by placing washers under the thread catcher or knife mounting
(see arrow).
