Rule:
When the handwheel pointer indicates “205” degrees (2.5-mm loop
stroke), the hook tip should stand at the needle axis at the stitch length
0. Length (A) = 1.5 mm, clearance gap (B) = 0.02 to 0.1 mm.
–
Turn the handwheel in the loop stroke position (2.5 mm) with the
indicator pointing to 205.
–
Loosen screws (1). Turn the hook tip (2) on the needle axis.
–
Loosen screw (3). Position the needle bar with the needle to the
dimension (A). Tighten screw (3).
–
Loosen two screws (4) and screw (5). Move the hook column (6)
from the needle.
–
Tighten screws (4) gently. With the help of screw (7), move the
hook column (6) to the clearance distance (B). Tighten screws (4)
and (5).
