Bajaj Auto was founded in the 1940s by Jamnalal Bajaj as part of the wider Bajaj Group, and it grew up in Pune, India, into one of the country's most important vehicle manufacturers. The company began building scooters under licence from the Italian firm Piaggio and went on to become a giant of Indian two-wheeler manufacturing with an enormous home market.

For decades the Chetak and other Bajaj scooters were symbols of affordable personal transport in India, robust machines that were easy to live with and simple to maintain, and Bajaj later expanded into motorcycles, including the popular Pulsar line, while becoming the world's largest manufacturer of three-wheelers. In recent years the Chetak name has returned on a modern electric scooter, showing how deeply the brand is woven into Indian motoring history.

The workshop manuals in this section cover complete engine service and overhaul, transmission and variator work, brakes, suspension, fuel and ignition systems, electrical and wiring diagrams, torque specifications, diagnostic procedures and the scheduled maintenance Bajaj recommends for each model. Procedures follow the factory sequence, with all measurements, clearances and settings listed for the exact model and engine variant.

They are of value to DIY owners who maintain their own Bajaj vehicles, independent garages across India and export markets, and collectors restoring classic scooters such as the Chetak with accurate factory information for their particular year of manufacture. With the correct data at hand, owners and workshops can carry out everything from routine service to a full rebuild with confidence.
