Threading; General Threading Information - Pfaff coverlock 4.0 Owner's Manual

General threading information

A color coded diagram is located inside the front cover for quick reference. Always start threading the loopers and then
the needles from right to left.
See the table below for recommendations on what needles and thread to use for different fabric weights.
Tip: Your new machine is threaded to sew a standard overlock. Tie your own threads to these threads and carefully pull them
through the machine, to easily thread your new overlock machine the rst time.
Note: If the lower looper should come unthreaded, do the following;
1. Unthread the needle(s)
2. Thread the lower looper
3. Thread the needle(s)
