1-Needle, Double Chainstitch, Bottom and Variable Top-Feed Machine (with Automatic Thread Trimmer)

The Juki MH-486-54U/PF3 is designed to deliver top-notch seam quality across a variety of materials, from lightweight to heavy fabrics. This high-performance machine features a precision-engineered presser foot, feed dog, and thread draw-out mechanism, making it user-friendly and capable of producing superior seams regardless of operator skill level.

Versatile Performance Across Multiple Fabrics

Adaptable to an extensive range of fabric weights and sewing processes, the Juki MH-486-54U/PF3 excels in handling light to heavy materials and supports complex operations such as partial shirring. Its flexible top-feed mechanism ensures uniform seam quality, even when sewing demanding materials or intricate patterns.

Advanced Features for Enhanced Sewing Quality

The machine boasts a suite of functions designed to enhance sewing precision and seam integrity. Its differential-feed adjustment lever simplifies switching between stretch and shirr stitching modes, allowing seamless adaptation to various sewing requirements. This adjustment capability is crucial for achieving consistently high-quality seams without puckering or feed irregularities.

Smooth Fabric Handling and Easy Adjustments

The Juki MH-486-54U/PF3 features a user-friendly design that allows operators to easily position fabric on the top-feed dog, ensuring smooth material handling. The machine’s forced lifting mechanism for the top-feed dog and its exclusive chain-off thread presser pedal foot improve operational ease and seam quality. Additionally, the machine’s gauges are easily replaceable, simplifying adjustments for different sewing needs.

Precision in Partial Shirring

Ideal for processes requiring partial shirring, the Juki MH-486-54U/PF3 works efficiently with an optional partial shirring device (PH-3) and shirring dial. This setup supports both kneepad and pedal drive types, enhancing the machine's versatility in handling specialized sewing tasks.

Enhanced Sewing Mechanisms

Equipped with a thread spreading mechanism, adjustable needle guard, and advanced thread control systems, the machine minimizes stitch skipping and ensures uniform thread length after trimming. These features collectively contribute to upgraded sewing performance, ensuring professional-grade results with every use.

Flexible Stitching Options

The machine offers the convenience of safety stitching (condensation stitching) to prevent loose stitches and reverse feed stitching (back-tacking) through simple lever adjustments. These options provide versatile stitching methods to suit a wide range of sewing applications.

Consistently Beautiful Seams

Standard features like a sliding presser foot and silicone oil lubricating unit work together to prevent stitch skipping and needle overheating, allowing the use of various thread types without breakage. This ensures consistently beautiful seams for light to medium-weight materials, maintaining high-quality results across diverse sewing projects.
