Hi everyone... I just bought an electric chain sharpener for my 18'' Poulan Pro. I felt asthough if I sharpened 2 chains the tool is paid for instead of buying a new chain every time it gets dull. My problem is that it tells you all about the product but not any technigue on how to sharpen the chain. If someone could steer me toward the most effective way to use this dremmel type tool, it will be highly appreciated! Dookiss2
