3-Thread Overlock - Wide
The 3-thread overlock wide stitch is perfect for edge-finishing most
woven fabrics and for seaming knits that do not require the extra
durability that a fourth thread provides.
To convert your serger to a 3-thread overlock wide (5.5-7.5mm), cut
the O-2 needle thread just above the needle eye. (fig. A)
Remove the O-2 needle and O-2 needle thread completely from the
machine. (fig. B)
Note: Do not tighten needle clamp screw(s) without needle being
inserted within the slot.
Move the stitch selector lever to "A".
For O-1 needle, 3-thread overlock, follow the suggested settings
and the threading diagram below.
