Dull chainsaw blades aren’t fun – not only they slow down your work, but they can also cause burning and buckling while sawing through wood. It can be dangerous!
Since the invention of the chainsaw, the task of cutting and felling tall trees has turned from laborious and time-consuming, to quick and effortless. Both professional and DIY builders and arborists use the chainsaw for cutting down trees and slicing through trunks.
The chainsaw’s efficiency is attributed to its motor and sharp blades, but over time the blades become dull. In order to keep your chainsaw consistent, you should sharpen the blades often. Even the largest chainsaws won’t cut with a dull chain. The good news is that you can sharpen the chainsaw back into its top condition easily, and it won’t take too long to do that.
How to tell when to sharpen a chainsaw
When the shavings cut from the chainsaw appear to be very fine and almost dust-like, then it is time to sharpen your chainsaw. Also, when the chainsaw has the tendency to “ride” in the cut without deepening it, it is an indication that you should sharpen it.
How to sharpen a chainsaw with by filing
While filing seems slow and tedious, most handymen consider it as the best and the most preferred way to sharpen a dull saw chain. Filing is probably the most common method of sharpening a chainsaw ever since the tool first came out. Once you perfect the techniques, you will actually find filing a pretty fast way to get a blunt chainsaw back to its razor-sharp form.
Make sure to wear protective gloves when filing a dull chainsaw.
- Engage the chain brake.
- Clamp the bar of the chainsaw to any work surface.
- If the chain is still loose on the bar, use a tension adjusting screw to tighten it.
- Mark the chainsaw tooth that you want to file first with a permanent marker. Marking it will enable you to keep track of where you started, and to avoid sharpening the same section again.
- If you have a roller file guide, place it between the rivets on the chain, with the arrows of the guide pointing towards the nose of the bar.
- Follow the angle of the tooth’s top plate; the rollers on the file guide will keep your file from going too deep in the tooth’s side plate.
- Start filing the first chainsaw tooth in steady, even strokes. Make about two to three strokes until the face of the tooth becomes sharp. It will become shiny silver.
- After sharpening a couple of chainsaw teeth, release the chain break and rotate the chain forward to reveal more teeth to be sharpened. After that, reset the brake.
- Once you’re finished sharpening the teeth on one side of the chain, flip the chain around so that you can begin sharpening the teeth on the other side of the chain.
- When sharpening, keep the chainsaw teeth out of dirt, or they will become dull.
