Using a chainsaw sharpener may seem daunting at first, but with this step-by-step guide on how to sharpen a chainsaw, you’ll be a pro with a sharp edge in no time.
1. Chainsaw sharpening should begin on the near side teeth, keeping the line on the guide parallel to the chain. A few light strokes on each tooth is enough.
2. Now sharpen the far side, keeping the back edge of the guide parallel to the chain. The same number of strokes should be done to each tooth to keep it balanced.
3. After completing the top bar, advance the chain with a gloved hand.
4. You'll notice the newly sharp edges immediately.
