• 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.

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, repalce both knives.
