How to Sharpen a Chainsaw?

Using a dull chainsaw is not only inefficient but also poses significant risks. Even a slightly dull chain can exhaust you and increase fuel consumption. If you suspect your chainsaw chain is dull, it’s crucial to stop and sharpen it by filing the cutters. Sharpening your chainsaw chain is a simple yet essential task that yields remarkable benefits.

It’s crucial to understand that filing alters the geometry of each cutter. Each time you file a cutter, it undergoes slight reshaping. Refer to a chainsaw cutter diagram to see how filing affects the relationship between the bevelled surface and the depth gauge (raker). The depth gauge restricts the amount of wood the cutter removes. Therefore, as you sharpen the beveled surface, the cutting edge’s height relative to the depth gauge decreases. To ensure proper wood removal, it’s important to file down the depth gauge after three sharpening sessions.

By mastering the art of chainsaw chain sharpening, you enhance both the efficiency and safety of your chainsaw. Enjoy precise cuts and a longer lifespan for your chainsaw by maintaining sharp and well-aligned cutters and depth gauges.
