Lombardini was founded in 1933 in Reggio Emilia, Italy, by brothers Adelmo and Rainero Lombardini, building on Adelmo's earlier experience making combustion engines since 1922. The company specialized in compact diesel engines and supplied them to a wide range of machinery builders across Europe, later becoming part of the American Kohler group.

Lombardini is best known for small air- and liquid-cooled diesel engines that combine light weight with dependable service. Series such as the LDW, FOCS and CHD families have powered generators, pumps, lawn and garden equipment, small tractors and construction machines, and Lombardini units are also found in marine auxiliary and generator duty aboard boats. Lombardini engines are often chosen where space is tight and reliable starting matters, from compact tractors and mini loaders to generator sets and pumps.

The manuals in this collection provide factory documentation for Lombardini engines, covering mechanical overhaul, fuel injection systems, cooling and lubrication, electrical equipment, torque specifications and diagnostic procedures. Scheduled maintenance information helps owners and technicians service the engines to the manufacturer's exact requirements. The FOCS and LDW families shown in the listings are among the most widely documented of the brand's designs.

These guides suit equipment owners, agricultural and industrial workshops, small-engine and diesel specialists and boat owners maintaining Lombardini-powered auxiliary systems. With factory procedures at hand, these compact diesels can deliver the long working life for which they are valued.
