How To Sharpen The Chainsaw

To sharpen your chainsaw, you will need a grindstone or a round file. As chainsaw teeth come in various sizes, the instrument you use will need to have a diameter that conforms to your saw. Before proceeding, you should clean your chain to remove any dirt or debris that will only hamper the sharpening process. You can use household cleaning detergents for this, though be careful not to get too much on other parts of the machine, as these products can damage it.

Some of the teeth on your chain can become redundant over time, and no amount of sharpening can heal them. Broken, worn or chipped teeth must be discarded before sharpening as they will only becoming increasingly dangerous. One of the reasons for sharpening a chainsaw is to make it safer to use, so looking for and removing damaged teeth is an important part of the process.

Your chainsaw should be set on a solid surface and clamped in a vice. Clamping the bar in a vice makes the sharpening process much safer. With the chainsaw stable, you can rely on more accurate results whilst increasing your safety.

To give you greater success, you should start from the lead cutter, which is the shortest cutter on the chain. The main aim is to file each tooth so that their flat edges are as close to being the same as possible. Ideally, you want entirely uniform cutters, which means each cutter should mirror the lead.

You must file from the inside-out, and file with both hands. The teeth on the chain face opposite directions; every other teeth will face you, and the rest will face away from you, depending on your own position to the chainsaw. The teeth must be sharpened from the inside face of the tooth to its outside face. As the teeth alternate the direction they face, you will need to adjust your saw, flipping it after you have successfully filed every other tooth.

There is no universally agreed upon direction for pushing the file. It is recommended to use a twisting motion as you glide the file across the cutter, which will help to discharge metal chips. It may be that you work out a direction which works best for you in achieving smoother cutting surfaces. The angle you file at will depend on your type of chain.

Before finishing, you may need to file any depth gauge that is sitting too high. You do not need to file the depth gauge every time you file the chain.

Then oil the chain before cutting again.
