Threading The Lower Looper (Yellow) - Pfaff coverlock 4.0 Owner's Manual

Threading the lower looper (yellow)

• Raise the presser foot to release tension discs.
• Pass the thread from back to front through the thread
guide on the thread stand (1).
• Thread the top cover thread guide by pulling the
thread towards the left until it slips under the guide.
Then pull the thread along the right side of the button
as illustrated (2).
• Lift up the handle and bring the thread under it. While
holding the thread with both hands, pass it between
the tension discs and pull it down to make certain it is
properly placed between the tension discs (3).
• Turn the handwheel toward you until the lower looper
extends out 10 mm (3/8") from the needle plate edge.
• Thread the looper area of the machine following the
yellow color coded thread guides (4-10).
• Place the thread through threading guide (4).
• Place the thread through the right slot of threading
guide (5).
• To thread the last thread guide (9), pull about 10 cm
(4") of thread through the guide (8).
Tip: Moving the stitch nger lever to R makes the threading
easier. Remember to set it back to N before starting to sew.
Option 1
• Place the thread into the "V" cutouts (A) on threader
lever. Pull the threader lever (B) up into place and
back to snap the thread into thread guide 9. Thread the
looper eye (10) from front to back using the tweezers.
Option 2
• Thread the looper eye (10) from front to back using
the tweezers. Make sure the thread runs into the "V"
cutouts (A) on threader lever. Firmly hold the thread
tail with left hand and pull the threader lever (B) up
into place and back to snap the thread into thread
guide 9.
