How to Sharpen a Chainsaw

If you regularly operate a chainsaw, you know that a sharp chainsaw not only makes your job easier, it makes it safer. A sharp chainsaw is easier to use and less likely to kick back when you hit a knot than a dull one. So cut down on costs and learn to sharpen your chainsaw yourself by following the steps listed below.

  1. Put on protective gloves and goggles. Sharpening your chainsaw will produce slivers of steel that can fly in unexpected directions. Always take the necessary safety measures when working with heavy machinery [source: Maxwell].
  2. Inspect your blades. Ensure that all the blades are intact. If you find any broken or chipped blades, replace the chain with a new one.
  3. Clamp the chainsaw to a vice. This ensures that the chainsaw won't move while you're sharpening the blade. If the chainsaw is not clamped down, you won't be able to properly sharpen the blades. Also, not securing the chainsaw can be dangerous to you.
  4. Attach a guide to the chainsaw's bar. Your chainsaw's bar has holes for fastening a sharpening guide. Different size teeth are sharpened with different size files. Determine which file to use and insert the file into the sharpening guide.
  5. Run the file along the blades of the chain. Keep in mind that you can only sharpen the blade by moving the file forward against the blade. Moving it in a backward motion won't sharpen the blade.
  6. Sharpen the blades of your chainsaw several times before replacing the chain [source: Cramer]. //]]]]> ]]>
