It includes sections on 'Instructions for Oiling', 'Instructions for Ordering', and a detailed index of parts categories such as 'Accessories', 'Feed Dogs', 'Needle Holders', and 'Throat Plates'.

Diagrams illustrating various assemblies and components are also present throughout the parts listings.

Instructions for Oiling: To ensure easy running and prevent unnecessary wear of parts in movable contact, the machine requires regular oiling. It is recommended to use "TYPE B" or "TYPE D" OIL, sold by Singer Sewing Machine Company, applied at least twice daily to all oiling points. "TYPE D" OIL is recommended when a minimum of stain on fabrics is desired, even after long storage. The felt pads on the side of each bobbin case should be kept wet with oil to lubricate the hook races.

Instructions for Ordering: Parts are ordered by using the PART NUMBER in the first column. The number stamped on a Singer Sewing Machine part is the number of the single part only, except when the part includes other components. The letter after the part number indicates the finish of the part (e.g., H-Hardened, Polished Nickel Plated, ALX-Heat Treated, etc.). Parts must be used when they appear in the list and after the number, as in the list.

The Singer 112W146 is a two-needle, high-speed sewing machine with ball bearing, drop feed, and safety clutch, suitable for vamping, foxing, space stitching, and tipping.
