– Make sure the chainsaw is turned off and unplugged.
– Remove the bar and chain from the saw’s body.
– Use a round file to sharpen the cutting teeth on the chain. The angle of the file should be about 30 degrees.
– File each tooth on one side of the chain, then turn it around and file the other side.
– Hold one end of the file with each hand. The file should be flat against the tooth’s surface, but not touching.
– File each tooth evenly until it is smooth along its entire length. It must include the hook at the base (the teeth should be sharpened symmetrically). You can also use a chainsaw sharpener, which can be purchased at most hardware stores.
– Reattach the bar and chain to the chainsaw body.
– Start the engine and allow it to run for a minute or two to check the chain tracking. If the chain is off track, adjust the screws on the side of the chainsaw until it is in the correct position.
