CLEANING AND OILING
Keeping your overlocker clean will keep your machine running smoothly and is a crucial component for successful stitches.
Serging creates a lot of lint which will build up in the machine, and oil will attract this lint to the moving parts of the
machine—so it is important to not over-oil the overlocker. Your machine manual will also give you detailed cleaning and oiling
suggestions..
PRESSER FOOT
The L 890 comes with two presser feet. Standard Combo Foot #C11 is the standard foot and can be used for all basic overlock
stitch groups and the Combo stitches. This foot can also be used for Cover-and Chainstitches. Chainstitch Foot #C13 is the cover-
and chainstitch foot and provides a narrower profile for optimal coverstitches and chainstitching.
NEEDLES
The L 8 Series overlockers are specified to needle system ELX705 needles. These needles have a grove on the front and
back of the needle which reduces the friction on the thread, especially at high speeds. Other needles can be used in these
machines, but tension adjustments may be required to achieve the desired stitch. Refer to Page 35 Reference - Overlocker
Needles for more information.
THREADING
(Refer to Page 36 Reference -Overlocker Threads for additional information about threads.)
Due to the One-Step BERNINA Air Threader, no specific sequence is required for threading the machine.
Thread with the presser foot raised, and the retractable thread guide fully extended.
Make sure needles are in the highest position—they are staggered.
• Follow the color-coded path for threading the desired stitch.
• To engage the air threader, turn the air threader connection to the left. Then press the foot control to activate the threading
motor.
• If the air threading pipes do not close in the proper position, turn the handwheel before engaging the air threader. Now
when you press on the foot control, the pulse-drive feature will slowly move the pipes into the correct position to close.
• Tools for changing needles are located conveniently inside the threading cover of the machine.
