Chain Finger
This
component is located
above the looper and
assists with forming the

overedge stitch forms
around the chain finger.
To adjust or set the looper height:
1
Loosen the 8 mm looper holder screw.
2
Rotate the handwheel until the looper passes under the chain finger with
0.5 mm clearance.
3
Tighten the looper holder screw.
4
After setting the looper height, set the overedge looper.
IMPORTANT!
These measurements are precise and should not be set
using the U.S. system of measurement.
