BSA A7 & A10 TWINS, '47-'62 HAYNES MANUAL

What sets Haynes Manuals apart is the attention to detail that goes into the production of each book. 

Every manual is written from hands-on experience based on a complete teardown, which is the step-by-step procedure of dismantling a particular vehicle part-by-part. This is followed by the detailed rebuilding of the specific model it documents. Writing each manual takes 30 man-weeks, with authors working as teams to shorten the production time and avoid fatigue during the difficult process. 

Hundreds of photographs accompany each manual's step-by-step instructions. The books are written from the actual experience of Hayne's own expert personnel using only a basic set of tools and presented in a style that any DIYer can follow, even a beginner. The DIYer can save a great deal of time and money, not to mention feeling proud of the job, by using a Haynes book.
