Overlock, super-stretch, flatlock, and rolled hem stitch capabilities.
One-touch air threading blasts thread through the loopers instantly.

Frustration-Free Setup
Automatic Air Threading
Engage the air connector switch and press a button to blast threads through internal looper tubes in seconds, cutting out one of serging's most tedious setup steps.
Quick Conversions
Color-Coded Thread Paths
Clear color-coded paths guide thread routing for quick 2-, 3-, or 4-thread conversions, making it easy to switch stitch types without guesswork.
Precision Finishing
Micro Thread Control (MTC)
MTC lets you adjust looper thread volume with a simple turn, ensuring stitches wrap cleanly around fabric edges without puckering or loose loops.
Fabric Handling
Differential Feed Dial
Differential feed eliminates waviness on stretch knits, keeping seams flat and professional-looking on even the trickiest materials.
Ergonomic Control
Free Hand System (FHS) Knee Lifter
Lower and raise presser feet hands-free using the FHS knee lifter, keeping both hands on bulky materials as you feed them through.
Project Flexibility
Free Arm & Slide-On Table
Convert to the narrow free arm for sleeve cuffs, or attach the expansive slide-on table to support heavy projects and long seams — the same machine adapts to both small and large-scale work.
Lighting & Organization
5 LED Workspace Lights & Onboard Tool Storage
Five bright LED lights illuminate the entire work bed, while onboard storage under the looper cover keeps essential tools organized and easily accessible between projects.
Cleanliness
Built-In Cut-Off Waste Bin
Trimmed fabric edges collect directly in the built-in cut-off waste bin as you serge, keeping your workspace clear without extra cleanup between seams.
Precision Adjustments
Cutting Width Dial & Rolled Hem Lever
The cutting width dial lets you fine-tune how much fabric the knives trim as you serge, while the rolled hem lever converts your machine for narrow, professional rolled hems on napkins, scarves, and delicate edges.
