Preparing the Chainsaw

The first step is to prepare the chainsaw by inspecting it for any damages or defects. Check if the chain is loose, bent, or damaged. Also, ensure that the chainsaw is free from debris or rust. Then, disconnect the spark plug wire to prevent accidental start-up. Finally, secure the chainsaw in a vice or clamp to keep it stable while sharpening.

Choosing the Right File

Choosing the right file is critical for effective chainsaw sharpening. The file size should match the chain pitch, which is the distance between the drive links. In 2024, you can find electronic chainsaw sharpeners that automatically set the right file angle and size. However, manual filing is still the most common method, and you’ll need to use a filing guide or template to get the correct angle.

Filing the Cutters

Start filing the cutters based on the manufacturer’s recommended angle, typically between 25-35 degrees. Use smooth strokes to file each cutter evenly, removing an equal amount of metal from each tooth. Keep the same file angle and pressure for each cutter, and use a magnifying glass to check for burrs.

Sharpening the Depth Gauges

The depth gauges or rakers are the small bumps in front of each cutter, which determine how deep the chain cuts. Sharpening the depth gauges is crucial to maintain the proper cutting depth and avoid kickback. Use a depth gauge tool or flat file to lower the depth gauges below the cutters by 0.02-0.03 inches. Be careful not to file too much, as it can reduce the chain’s efficiency.

Lubricating and Testing the Chain

After sharpening the chain, lubricate it with chainsaw oil to reduce friction and avoid rust. Then, reinstall the chain, adjust the tension, and test the chainsaw’s performance. A sharpened chainsaw should cut smoothly and effortlessly, without any rough or irregular cuts.
