How to Sharpen a Chainsaw Mechanically

The invention of the chainsaw has certainly made yard work much easier. From cutting logs for the fireplace, to removing branches and even cutting planks to build your very own deck, the chainsaw does the job. But after a few of those jobs, it will need to be sharpened. Here's how to sharpen your chainsaw mechanically.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Chainsaw chain
• Chainsaw sharpener
• Work gloves
• Protective eye-wear

1. Place your chainsaw chain on the chainsaw sharpener. These are machines specifically designed from mechanically sharpening chains. Loop the chain so that it sits down into the provided track.

2. Set the angle at which you would like to sharpen your chainsaw teeth. Most of the time this is 25 degrees, however you should check the owner's manual for the specific angle at which your chain should be sharpened.

3. Put on working gloves and protective eye-wear. This is a must, as sparks are about to fly.

4. Turn the machine on and lower the sharpening edge toward the chain. Touch the edge to the chain a couple of times, lightly bouncing the machine. You don't want the sharpening edge to simply grind on the chain.

5. Rotate the chain on the track so that you sharpen each tooth in your direction until you've finished the entire chain.

6. Switch the sharpening blade position and angle so that you can catch the underside of the teeth. This will allow you to get an even sharpening across the entire chain. Repeat this until you mechanically sharpen the whole thing. The chain is then ready to place back on the chainsaw.

Tips & Warnings

• Sparks will fly when the sharpening edge hits the chain. Don't be alarmed, this is perfectly normal. Just don't wear clothes that are abnormally flammable. Also, long-sleeves and pants are a must.
• Don't let children use this machine. There are other jobs around the shop they are better suited for during the course of a project.
