This document is a service manual for Speed Queen commercial washing machines, issued in 1971 by the McGraw-Edison Company Service Department, located in Ripon, Wisconsin. Designated as Part No. 24119, the publication provides technical instructions for servicing commercial agitator-type automatic washers manufactured during the early 1970s. The cover employs a mid-century graphic design with a building-block motif to represent the “ABC’s of Service” components: Agitator, Bearing, Collar, and Solenoid. As a primary-source document, it constitutes a reference for understanding American commercial laundry equipment of that period. The manual encompasses the A213 through A219 series, the metered MA series (including MA215B and MA216B), and the CA series models (CA2150, CA2401, CA2421, among others). Its contents are divided into three sections. Section I addresses service procedures for components such as the timer, mixing valve, agitator, spin tub, and transmission. Section II provides adjustment instructions covering leveling, belt tension, and the door safety switch. Section III contains a troubleshooting guide for issues including failure to fill with hot water, continuous water filling, and excessive vibration during the spin cycle. The interior includes technical line drawings and exploded-view diagrams depicting the sediment tube, balance ring assemblies, and spin tub cap screw locations. The physical condition of the manual reflects typical workshop use. The pink/magenta paper cover exhibits shop-wear, including foxing, staining along the left edge and top left corner, and handwritten pencil notations, one possibly indicating a price mark. The manual is three-hole punched. Interior pages show age-related toning and edge wear, but text, diagrams, and troubleshooting charts remain legible. The document provides repair information and insight into the design and service philosophy of Speed Queen commercial appliances during the McGraw-Edison ownership period.
