1975 Singer ATHENA 2000 Sewing Machine Operator's Guide (P/N 173122)

Singer’s ATHENA 2000 operator’s guide covers machine setup, sewing functions, and owner maintenance. It is identified as Form 21680 (Rev. 576), P/N 173122, with an included quick-reference sheet, Form 21681 (Rev. 1275), P/N 173124. Its scope is operation and basic troubleshooting; internal repair procedures and electrical wiring diagrams are not included.

• Stitch controls: Electronic stitch selection, speed controller operation, the Individual Preference Panel, pattern repeat, reverse sewing, and stitch width, length, and reverse stitch-balance adjustments.

• Threading and bobbins: Single- and twin-needle threading, in-place bobbin winding, bobbin removal and replacement, needle-thread tension adjustment, and presser-foot pressure regulation.

• Feet and plates: Attachment instructions for snap-on and button feet, the Even Feed Foot, Darning and Embroidery Foot, and chainstitch plate and insert.

• Buttonholes: One-step, two-step, and corded buttonholing, including buttonhole-lever operation, density balancing, and stitching a series of matching buttonholes.

• Owner care: Illustrated cleaning locations, light-bulb replacement, circuit-breaker reset, and symptom-based troubleshooting in the Performance Checklist.

This guide is suited to owners learning the ATHENA’s controls, with illustrated explanations of everyday setup and sewing operations.

Stitch Controls, Threading and Attachments

Electronic Sewing and Individual Preferences explain how programmed stitches relate to manual width and length settings. Reverse stitch balance is covered for Flexi-Stitch patterns and buttonholes, while the pattern repeat button is explained for individual decorative motifs.

The threading drawings distinguish the single- and twin-needle paths through the tension discs. Bobbin-winding and replacement illustrations show the thread route, while the machine overview identifies the slide plate, bobbin latch, and transparent bobbin.

The tension dial adjusts needle-thread tension only; bobbin-thread tension is factory-set. The accessory illustrations identify the secondary spool pin and special-purpose foot, alongside the interchangeable sewing attachments.

Views labeled Attaching Even Feed Foot and Attaching Darning and Embroidery Foot accompany the fitting instructions. Chainstitch coverage explains the plate and bobbin-case insert, and the Flip & Sew panel is covered for free-arm sewing.

Using a twin needle without activating the twin-needle switch can break the needle. The bobbin section also warns that pulling thread across the soft-touch feed while emptying a bobbin can damage the feed.

Buttonhole Methods and Density Adjustment

One-step and two-step buttonholing are explained separately, including their different lever operation. The Balancing the Density illustration identifies the controls used for the sides of the buttonhole, and corded-buttonhole drawings show filler-cord placement for both feet.

Button-foot attachment is covered, but instructions for sewing buttons onto fabric are referred to a separate Sewing Applications book, which is not included.

Owner Care and Performance Checks

Cleaning drawings mark accessible lint-removal points, and the lamp section illustrates bulb locking and unlocking. The machine requires no oiling under normal conditions; permanently lubricated internal parts are assigned to dealer servicing.

Disconnect the power cord before cleaning or changing the bulb.

The Performance Checklist relates failure to start, missing stitches, fabric puckering, feed problems, and thread breakage to specific setup checks. This helps owners check threading, bobbin condition, and control settings before seeking repair.

Circuit-breaker coverage distinguishes access on portable and cabinet installations and directs repeated tripping to a Singer representative or approved dealer.

A Preview of Needle and Buttonhole Guidance

These examples are a small selection of the needle and accessory guidance in the manual.

For general-purpose sewing, Singer specifies Style 2020 needles in sizes 9 through 18. The needle section also distinguishes ballpoint, twin, and leather needles by application.

One-step buttonholing is described for flat buttons up to 1 1/8 inches across. Larger buttons, or buttons of unusual shape or thickness, use the two-step method.

PDF Search, Navigation and Page Breakdown

Text search and navigation: Search is partial and affected by OCR errors. The quick-reference pages and machine/accessory identification pages have no searchable text, and the Performance Checklist body is also outside the text layer. There are no embedded PDF bookmarks.

One printable, 25-page PDF combines the 23-page operator’s guide, including its front and back covers, with two quick-reference pages at the beginning. Those additional reference pages are already included in the total.
