16.1 Setting the height of the thread-pulling knife

between the upper edge of the knife carrier (4) and the hook bearing screw-
on surface (3) is 10.7+
0.05 mm. Fine adjustment is made by means of wash-
ers between the knife carrier (4) and the thread-pulling knife (2).
Important
When changing the knives, make sure that you do not lose the washers.
Proper setting
The thread-pulling knife (2) pivots as close as possible above the hook
and is at the same height as the counter blade (1).
