If you wish to do repairs on your TVS Scooty then it is usually a great idea to possess a Workshop Manual for a reference just in case you want to know the right way to take out a specific part for example the Brake Pads and fit it again in the correct manner.
TVS Scooty Workshop Manuals are able to offer certain diagnostic information on your vehicle so if something is not working it can help you ascertain what the problem is and methods to repair it. You will be able to determine if this can be done yourself or that the job is simply too big you could book your Scooty into a decent friendly mechanic.
