10.1 Turn the balance wheel in sewing direction until the point of the advancing
looper is at the right-hand side of the needle.
10.2 In this position, attach C-clamp No. 08-880137-00 to the needle bar so that it
contacts the needle bar frame (thus blocking the upward motion of the needle
bar).
10.3 Turn the balance wheel in the opposite direction until the C-clamp contacts the
needle bar frame again.
10.4 in this position, the looper point should again be at the right-hand side of the
needle.
10.5 if it is not, loosen both screws 1 (Fig. 10.0.1) in the gearcase so that gear 2 can
just be turned by hand.
10.6 Remove the C-clamp and tum gear 2 to the required position.
14.7 Repeat steps 10.1 through 10.4.
10.8 After these adjustments, remove the C-clamp again and tighten both screws 1.
