Setting Up Your Serger
When threading, it’s important to consider the type of thread you use for serging. Remember, a serger
creates a finished look with reinforced stitches, so strong thread is an important ingredient. A top quality, long
staple, polyester or poly/cotton blend is the best choice. Skipped stitches and broken threads are often the
direct result of using old or inferior thread.
Preparation For Threading
Setting Up the Thread Antenna
• Take out the thread antenna from the top of
styrofoam, and insert it as shown in first illustration.
• Fully extend the thread antenna.
• The two joints on the telescope will click into place
when they are correctly positioned as shown in
second illustration
• Center the thread guides above the spool pins.
• Place thread over the cone adapters on the spool
pins.
Thread Net
When using synthetic threads that easily spill off the
cone, slip the thread net furnished with the machine,
over the thread from bottom of the cone leaving the
thread end hanging free at the top as shown on the
right.
