How Does Electric Chainsaw Sharpener Work

Over the years, chainsaws have become a handy and necessary tool for both professionals and homeowners with many trees. However, there not seem to be enough information about maintenance or care of these machines, let alone a subject that appears to be forgotten entirely and creates many doubts for the users of these machines, we are talking about the sharpening of the chain of chainsaws

Yes, if you did not know, the chain saws need to be sharpened with some frequency, and in fact, you could do it yourself with the help of some special tools and previous specific training. Below, we will explain how the electric chainsaw sharpener works, but we will also give you some recommendations that you could use if you do not have a sharpener for your machine. 

How to Sharpen the Chain on a Chainsaw with a Sharpener

If you are an amateur or a professional chainsaw user and you use chainsaws frequently, then you should know how useful the chainsaw grinder is, in addition to its ease of use, money-saving, and other drawbacks. Now we will explain step by step how to use the chain sharpeners and also how they work. 

Understanding Your Chainsaw Specifications 

Just like any other power tool, you must understand the specifications of your saw before you start sharpening, especially the blade. This information can be found in the user’s manual or in the manual that came with the blade. In case you do not have the manual, you can look up the specifications of your machine on the internet. 

Prepare the Sharpener

Once you know the specifications of your chainsaw, it is time to prepare the sharpener. To do this, place it on a strong enough workbench. Attach the sharpener using the holes in its base. During this step, the locking wheel must be free for access. 

Some sharpeners have the option of operating them on the floor, this tool does not have a unique design. 

Wheel or Grinding Stone Assembly

When the sharpener is securely in place, lift the housing from the top of the sharpener and adjust the locks. This allows the adjustment of its upper position. And now remove the cover of the whetstone with the help of a screwdriver. 

Turn the cover that locks the grinding stone and install the wheel that the base requires. Make sure you are putting in stone or wheel that can sharpen your chainsaw the right way. 

Adjust the grinder’s locking cap and then the wheel cover. Release the top cover and lower the top cover again. 

Prepare the Chain

As mentioned above, it is necessary to remove the chain from the chainsaw to sharpen it on the grinder. Also, be sure to clean the chain using a solvent of your choice. Allow the chain to dry completely, and now lift the chain stops and slide it onto the sliding tracks. 

Put the chain in its place on the sharpener and adjust it well, so that the disc can rest on one tooth of the chain, which is where you start

Select the Correct Turning Angle

In step 2, we did something with the locking wheel, in this step, you must loosen this wheel so that it can turn freely, helping you to define the right angle for precise grinding. 

You need to remember that not all chainsaws have the same calibers on their chains, they can vary in size and even in angle. If you are not sure what the right angle is, recheck the specifications. Generally, most chainsaw links have an angle ranging from 0 to 60 degrees. 

Adjust the locking wheel to the degree required by your chainsaw. Once you have positioned the correct angle, readjust the locking wheel from the bottom and lower the upper housing so that the stone or grinding wheel can slightly rub against the blade. 

Also, adjust the locking stop, this will keep the grinding wheel from cutting the chain any more than it should and will not cause damage or overheating. 

Now lock the chain rail by turning the handle just next to it, and you should be ready to start sharpening your chain. 

Sharpen the Blades

It’s time to connect the sharpener or turn it on. Once turned on, start slowly lowering the wheel or whetstone. When contact with the chain generates sparks, it may take a few seconds to sharpen a tooth on the chain. 

When you are finished with one tooth, turn off the sharpener, pull the chain gently until another tooth is left on the stop, and proceed to sharpen it. Continue until the entire chain is sharp. 

Once you have finished with one side of the chain at an angle, turn off the sharpener and unplug it. Loosen the grinding wheel at the bottom and turn it in the other direction. Readjust the angle that you had previously set, and adjust the chain tooth into position at the locking stop, and lock the wheel or grinding stone. Plug the machine back in and sharpen as before. 

You can check that the chain is well sharpened, noting that each tooth looks sharp and shiny. Once it is ready, put it back on the chainsaw and make the necessary tests. 

Additional Tips

  • Avoid using a whetstone that is cracked or broken. 
  • Wear safety glasses while sharpening the chain.


Reading through each step in sharpening the chain on your chainsaw may seem like a challenging thing to do, but once you’ve done the first part of the process, you’ll find it’s quite simple, especially if you already have experience with power tools. 

Also, sharpening a chainsaw with a grinder is much faster and more effective than doing it manually. Just by following these steps, you will be able to sharpen your chainsaw like a professional, and you don’t have to be one to do it, you just have to pay attention to what you are doing and use the right sharpener
