Kenmore 16951 Model 385 Zigzag Sewing Machine Owner's Manual (P/N 650800012)

The 56-page original factory owner's handbook details the operation, maintenance, and parts identification for the 1980s Kenmore 16951 (Model 385-series) zigzag sewing machine. As an official Sears Canada PDF publication (Part No. 650800012, originally printed in Taiwan), it provides the exact manufacturer specifications required for workshop maintenance and daily fault isolation.

• 24 distinct component illustrations and exploded-view parts diagrams
• Diagnostic performance charts for mechanical evaluations
• Needle and thread compatibility tables based on fabric weight
• Authorized maintenance and adjustment procedures for standard variants
• Push-pull clutch, stretch stitch adjuster, extension table, presser foot lever, bobbin winder, shuttle mechanism, darning plate, zipper foot
• Blind hemming, shell stitching, box stitching, fagoting, satin stitching, appliqueing, smocking stretch, rick-rack stretch, herringbone stretch

Operating Procedures and Maintenance

This guide maps out the setup and mechanical use of the 385-series. It breaks down the threading sequence for both the bobbin and top thread, alongside presser foot installation and pressure regulator adjustments. You will find the exact factory guidelines for configuring stitch width and length, including optimal settings for varying fabric weights. Before performing any internal maintenance or checking the electrical components, always disconnect the machine from power to prevent accidental startup or electric shock. The performance diagnostic section isolates common malfunctions—like skipped stitches, thread breakage, or feed dog issues—matching probable causes with their direct mechanical corrections. It also covers periodic care, featuring step-by-step instructions that can save a costly repair shop visit, such as safely clearing severe thread jams from the shuttle race, replacing the sewing light bulb, and correctly adjusting the stretch stitch balance. Clear diagrams show how to access the face cover, arm, and underside mechanisms for shuttle maintenance, feed dog cleaning, and internal lubrication. Visual aids such as bobbin winding sequence views, threading channel schematics, and shuttle assembly drawings provide exact baseline references.

Technical References and Specifications

The documentation provides critical specifications for matching needle types and thread sizes to fabric loads, ranging from lightweight batiste to heavy upholstery canvas. Technicians will find standard stitch length settings, such as the baseline 10 to 12 stitches per inch for medium-weight fabrics. Having these exact factory baseline specifications at the workbench prevents tension imbalances and allows mechanics to restore original stitch quality without trial and error. Electrical requirements for the motor and lighting circuit are confirmed at 110–120 volts AC. An included parts list aids in quick component lookups, making it easier to source replacements for the bobbin box, foot control, or specific guide feet during a mechanical repair. The manual logs reference values for tension control and stitch length adjustments regarding buttonholes, blind hemming, and stretch stitching. Detailed stitch selector charts and lubrication point views further assist in verifying accurate machine operation. The service data provided within the publication is intended as a technical reference, and all hands-on adjustments should align with standard safety practices for motorized equipment.
