If you want to sharpen the blade teeth, you will need to use a chainsaw sharpener file. Using the file to sharpen the blade chain on your chainsaw is not difficult at all, and this simple how-to article will show everything you need to know. Let's get started.

Step 1 - Clean the Chain

Take an old toothbrush and some mineral spirits or other degreaser solvent to clean the chain on a chainsaw. When cleaning the chain, make sure to get in between all of the blade teeth and also cleaned beneath the chain where it is attached to the chain bar.

Step 2 - Align Chainsaw File

Generally speaking, you can start at any point on the chain you want when you start sharpening the teeth on the blade chain. So, choose a tooth on the chain to start at and place the chainsaw sharpener file in the groove or notch on the front part of the tooth. Do not start filing just yet.

Step 3 - Lift File to Appropriate Angle

Before you start filing the blade tooth on the chain, you'll need to make sure that you are holding the file at the right angle. In most cases, you'll need to tilt the sharpener file to an angle of about 25 or 30 degrees. However, you should refer to the operating instructions that come with your chainsaw to make sure that the angle is correct.

Step 4 - File Chainsaw Tooth Blade

Once you have the sharpener file at the correct angle of the blade tooth on the chain, you can begin filing to sharpen the tooth. When moving the sharpening file back and forth, twist the file clockwise and counterclockwise while making your filing strokes. This will help to shake off dust from the metal tooth on the blade and file and also help you to sharpen the teeth faster. When filing the tooth, don't overdo it. You only need to push the file back and forth 3 or 4 times.

Step 5 - Repeat for All Other Blade Teeth

After you finish filing the first tooth on the blade, repeat the process for all of the other teeth that point in the same direction. You will need to advance the chain on the chain bar by spinning it with your hands. When doing this, be very careful or you may cut your hands.

Step 6 - File All Cross-Angle Blade Teeth

Once you have completed filing all the teeth that are angled in the first direction, take and reverse the position of the sharpener file. Then repeat the process for all of the cross-angle teeth on the chainsaw blade chain.

Step 7 - Oil the Blade

After you have finished sharpening all of the teeth on the chainsaw chain, you will need to thoroughly oil the blade. To do this, take some bar oil and put it into a squeeze bottle. Then, apply a few drops of oil along the chain surface. Also, if your chainsaw comes equipped with a oil pump to lubricate the blade, make sure it is filled it and use it to lubricate the chain on a chainsaw as well.
