#4 File The Chain

To get excellent sharpening results, you have to follow these procedures and notices to know how to sharpen a chainsaw with a file.

  1. Firstly, you have to keep the chainsaw in a steady position by clamping its bar in a vice and placing the saw on a non-slide surface.
  2. Next, position the guide between the chain’s rivets so that the guide’s arrow icons will face the bar’s nose.
  3. Insert the round file into the file guide. The recommended horizontal angle of the file should be from 30 to 35 degrees. These are the common angles of a saw’s upper side which will assist you in maintaining the angle while filing.
  4. Mark the starting point on the saw’s top before you start the sharpening process.
  5. When making some first strokes, your hand will feel a slight vibration because of the dull blade. To ensure safety, you should keep the chainsaw away from your body parallel to the non-slide surface with the recommended angles. At this time, the file guide moves on the depth gauge and the saw.
  6. You should perform even and steady strokes for every cutting edge. 5-6 strokes for each one are adequate to make the blade shiny. Apart from noticing the outside condition of the cutting edges, you can listen to the “burr” filing sound to know whether you have completed your task or not.

  1. Check the lineup of the file and the blade by looking via the file guide. You have done an excellent job if you see the blade and the file completely fit into the guide. Keep doing what you are doing.
  2. After filling some edges, you should rotate the chain for its other cutters coming up. Remember to wear gloves for protection because we are showing you how to sharpen a chainsaw by hand.
  3. While sharpening the blade, you can check the depth gauges’ height simultaneously by using the file guide. In case the gauges’ height exceeds the guide, it’s time for you to make them flush by using the flat file.

Accomplish all of these steps, and you now know how to sharpen a chainsaw chain with a file.

#5 Continue With The Other Cutting Edges’ Side

Using the file guide allows you to cut one side of the blade only. Therefore, you will need to repeat all of the steps above for the other side.

#6 File The Rakers

Since rakers’ purpose is to keep the wood crust from staying on the chainsaw, they are lower than the cutting edges. These parts support your cutting if the blade is in its optimal condition. However, when the blade becomes dull, rakers will somehow be a hindrance to your cutting.
