Used Overlock Machines in Jiangxi, China

Inspect loopers, needles, knife blades, tension discs, and differential feed. Run the machine with different fabrics to check stitch quality, trimming, and noise. Verify motor, electrical wiring, pedal, and any included accessories. Ask for maintenance records and part availability.

Choose 3- or 4-thread machines for general seams and edge finishing; 5-thread safety stitch for extra strength. Use differential feed and narrow stitch settings for knits and stretch fabrics; heavy-duty models for denim or upholstery.

Securely clean and pack the machine, remove or secure loose parts and thread, protect knives and protruding components, and crate industrial units. Use a carrier experienced with sewing equipment, insure the shipment, and confirm voltage and plug type for your destination.

Clean lint and dust after use, oil points per the manual, replace needles and worn blades, check belt tension, and periodically inspect timing and loopers. Schedule professional servicing for timing or electrical issues.

Run it at working speed with woven and knit samples to check stitch formation, seam strength, and trim quality. Listen for unusual noises, test the knife, pedal response, and light, and confirm smooth differential feed operation.

Availability depends on brand and age. Popular domestic and industrial brands have good aftermarket support; for older or obscure models, check online marketplaces, dealers, or service shops and request part numbers and manuals before buying.
