Things You'll Need:
- Chainsaw round files
-
Step 1
Visit the local chainsaw shop and take your chain with you. Ask the clerk for a few hand files that are the right size for your chain. The most common sizes are 1/4-inch and 3/8-inch files. The file has to be the correct height and width to fit your saw's teeth. The files will be inexpensive to purchase---only a couple of dollars each; buy plenty if you do a lot of wood cutting.
-
Step 2
Note that every second tooth on your chain is pointing in the opposite direction. This means that you will first have to sharpen one set of teeth and then turn the saw around and sharpen the other set of teeth.
-
Step 3
Set the chainsaw in front of you with the chain on the saw. It is easier to sharpen your chain while it is on the saw. You may want to use a table for sharpening.
-
Step 4
Use a gliding stroke forward towards the tip of your file at a 7-degree upward angle and sharpen only in one direction. It will usually take five strokes for every tooth to get sharpened to the same degree; when using the same amount of strokes per tooth. If you use a different number of strokes on each tooth, your saw will pull in one direction, making it harder to keep in one position.
