2.12.4 Position of the counter-knife in respect to the thread pulling knife

36
Caution: Danger of bodily injuries !
The machine must be in the position "Safe motor stop ".
Rule and control
–
The counter-knife support 4 should bed as close to the rear casting
edge as possible.
–
During the thread cutting process, the pressure of the
counter-knife 1 against the thread pulling knife 2 should be as low
as possible, but it should still be sufficient to ensure safe thread
cutting. Normally, this will be ensured if at the moment when the
knifes are half overlapped the blade of the counter-knife just
touches the thread pulling knife.
Correction
–
Lower the sewing head by the function "Lowering/lifting the
sewing head".
–
Press the key "O".
"Safe motor stop " will be switched on.
–
Loosen the screw 5 or 2 and shift the counter knife support of the
counter knife accordingly.
–
Tighten the screws.
ATTENTION !
An excessive counter-knife pressure will result in an increased knife
wear..
