• Lift the entire presser foot by the handle at the back when accurate fabric placement is needed.
• Use the 2-step presser foot lifter for thick fabrics.
• Chain off the fabric.

Cleaning and Oiling
Owner's manual pg.___
• Clip all threads at the thread guide support.

• Gently pull threads from serger. Always remove threads in the direction of sewing. If you encounter any
resistance, stop and rotate the handwheel slightly to release the threads from the loopers.
• Open the looper cover; rotate the upper knife up.
• Using a vacuum cleaner adapter or a 1" cosmetic brush, remove all lint and fluff from the looper, knife
and feed dog areas of the machine.
• Following the oiling guide inside the looper cover, place a drop of oil on each of the two oiling points.
• Remove old needles and replace them with new.
• Rotate upper knife down into cutting position.
Replacing the Knives
Owner's manual pg.___
• Serger knives cut fabric as it is serged; as with scissors, repeated use can dull them. If knives begin to
"chew" instead of cut, consider replacing the lower knife.
• If you serge over pins, replce both knives.
