.05.01 Position of the needle in the needle hole
Requirement
1. The needle 6 must be centered in the needle hole in a crosswise direction.
2. The distance between needle 6 and the front edge of the needle plate must be ap-
prox. 0.8 mm. (In the case of machines with -911/... the needle 6 must be centered in
the needle hole in the sewing direction.)
● Loosen screws 1, 2, 3 and 4.
● Shift needle bar frame 5 according to the requirements.
● Tighten screw 3 securely and slightly tighten screw 2.
● Using screw 1, pull the guide stud behind it against the eye of the needle bar frame 5
and tighten it.
● Loosen screw 2 and turn the balance wheel a few times (this helps to avoid the oc-
curence of any tension).
● Tighten screw 2.
● Tighten screw 4, making sure that the slotted guide is parallel to the needle bar.
