The stopper screw 2 limits the lift when the knee lever is pressed all the
way to the right. This prevents a collision between the sewing feet and
the needle bar.
–
Lift the sewing foot using the knee lever.
–
Check whether the needle bar does not hit the lifted transport foot.
Caution Risk of Injury !
Turn the main switch off !
Set the stopper screw only with the sewing machine turned off.
Correction
–
Loosen lock nut 1.
–
Set stopper screw 2.
The clearance between the stopper screw 2 and the lever 3 should
be 0.5 mm when the sewing feet are fully raised.
–
Tighten lock nut 1 again.
