Husqvarna Chainsaw Chain Sharpening Angles
What Angle Do You Sharpen A Chainsaw Chain?
The cutting angle is the same angle as the laser-cut line you will find on the top of each tooth.
To file the cutting angle, you need a cylindrical chainsaw file with the proper diameter for your chain; 3/16 inches is a common diameter. Place the filing gauge on the chain with the arrows pointing toward the nose of the bar, and then adjust the file so it contacts the rollers on both sides of the gauge. This automatically adjusts the file to the proper angle, which is between 25 and 35 degrees, depending on the chain. File every other tooth, and then turn the chain and file the teeth facing the other way.
How Do You Sharpen A Chainsaw With A Filing Guide?
The bevel on the top of each tooth determines how much wood it removes with each pass; if it isn’t filed regularly, the chain becomes dull. Over-filing is also bad for the saw, because it cuts too deeply and overworks the engine. File the depth gauge every fourth time you sharpen the cutting angle. After setting the tooth inside the gauge, file the top of the tooth with a flat file until the file contacts the gauge.
How Many Times Can A Chainsaw Chain Be Sharpened?
On many chains there is a line on the rear of the top plate. This is the witness mark, showing that the chain can be sharpened back to that line and still cut effectively.
