How To Sharpen A Chainsaw Using A File

When cutting wood with a chainsaw, nothing can be more infuriating than the blunt teeth of the saw. A dull chain requires more human effort so as to go through the wood, and hence, it ends up wasting time. But more importantly, a dull chain can get you injured because it has a high tendency of sticking in the wood. This may result in a jerky behavior that may lead to a kickback. Your machine is also at risk of failing because a dull chain forces the engine to strain so as to provide more power. The good news, though, is that you can always sharpen the chain whenever it becomes dull.

How To Sharpen Your Chainsaw Using A File

Before you begin, ensure you have the right tools for the job. They include a round file, a flat file, a file guide, and a depth-gauge filing guide. And for a good finish, try to hold your chainsaw steady. A bench vice, for instance, would come in handy for such a job.

After securing your power tool, take your file guide and position it over the cutter. The cutter is the tooth of the saw and the file guide helps you to hold the round file at the right height. Then take your round file and place it within the cutter and across the file guide. Sharpen the cutter by moving the file from right to left or left to right. The motion, however, must begin from inside the cutter to outside.

And of important to note is that if you are stroking the first cutter from left to right, you must maintain your direction in all the other cutters. And the same rule applies if you are moving in the opposite direction. Give each cutter a few strokes -- which must be equal -- and when you are through, move to the other side. This means that you have to reverse your motion. If you sharpened the cutters from left to right, start moving from right to left.

Problems That Arise When Sharpening The Cutters

In front of each cutter there exists a depth-gauge fin -- a piece of metal that is shaped like the fin of a shark -- which controls how deep the tooth of the saw or cutter goes into the wood. The depth-gauge fin should be a bit shorter than the cutter. But after sharpening the cutters, you may find that some of them are now at the same level with their adjacent depth-gauge fins. This affects how the cutters bite into the wood and you need to re-adjust the setting by filing the fins using a flat file until they become a hair shorter than the cutters.
