Briggs & Stratton was founded in Milwaukee, Wisconsin, in 1908 by inventor Stephen Foster Briggs and investor Harold M. Stratton. The partners originally planned to build automobiles, but they turned instead to small engines and began producing them in earnest after the First World War, eventually becoming the largest manufacturer of air-cooled gasoline engines for outdoor power equipment in the world.

Briggs & Stratton engines are known for simple, rugged, air-cooled design and are found in lawnmowers, garden tractors, generators, pressure washers, tillers and countless other machines. Notable families include the long-running L-head engines, the overhead-valve Intek and ELS series, and the commercial-grade Vanguard engines, spanning everything from small walk-behind mower units to larger industrial and rental-duty engines. Each engine carries a model, type and code number that identifies its exact specification for parts and service.

Briggs & Stratton workshop manuals cover the complete engine: cylinder, valve train and governor, piston and crankshaft, carburettor and fuel system, ignition and charging systems, air cooling and lubrication, plus the wiring diagrams used on electric-start models. They include torque specifications, valve clearance and carburettor settings, diagnostic procedures for starting and performance faults, and the maintenance schedule recommended for each engine family.

These manuals are essential for homeowners who service their own equipment, small-engine repair shops, and dealers and technicians who need factory data to repair Briggs & Stratton engines quickly, correctly and safely.
