15 Thread trimmer
15.1 Adjusting the height of the thread-pulling knife
Fig. 56: Adjusting the height of the thread-pulling knife
The height of the thread-pulling knife is factory-set so that the distance A
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 washers 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 closely as possible above the hook
and is at the same height as the counter blade (1).
WARNING
Risk of injury from sharp and moving parts!
Cutting and crushing possible.
Switch off the machine before adjusting the thread
trimmer.
