ANGULAR POSITION OF UPPER LOOPER
9
1. Remove: Mains lead - Machine base.
2. Make sure that there is no axial play neither on the upper looper shaft "a" nor on
the 2 pivoting axles "b" and "c".
3. Bring upper looper to its far left swing position.
4. Loosen screw "d" just enough so that lever "e" articulates with friction and adjust
lever "e" angularly to obtain a 5.6mm gap between point of looper and the left side
of the overlock needle.
5. Tighten screw "d". It is very important that the machine turns quite freely without
any biding effect caused by an axial shifting from lever "e".
6. Check clearance and timing of upper looper to lower looper.
