This book was written to try and help homeowners and contractors save money on their tool repairs. I have used pictures of tools to help in identifying parts that you may have never seen. I have maintenance tips as well as repair information for the most popular tools. There are tips on buying tools as well as how to choose an extension cord. I believe if you save or repair one tool by using this book, you have gained more than what you paid. You can do it, let me help you.
