How to Replace the Chain on a STIHL Chain Saw

Stihl chainsaws use a chain that you can sharpen several times before you must replace it. The average homeowner will have a chainsaw for years before they need to replace the chain. If you use your chainsaw on a regular basis, you may need to replace the chain more frequently. The process for replacing the chain with a new one is actually quicker than sharpening an older blade.
