Conversion to 2-thread overlock
1. Open the front cover. Bring the upper
looper to its lowest position by turning the
handwheel towards you.
Put 2-thread overlock convertor on the upper
looper.
2. Push the projection (A) of convertor and
insert the tip (B) of convertor into the eye
(C) of upper looper.
Since above settings are based on normal weight thread, it may be necessary to adjust the
thread tension according to the stitch pattern and type of fabric and thread you are using.
The differential feed is normally set at “N”.
