How To Put a Chain on A Chainsaw

Anyone who works in the woods or lives in rural areas knows pretty well how important chainsaws are. Even if you live in an urban area, there are many tasks one needs to do with the help of a chainsaw. If you are using a chainsaw often you should always be aware of how to work with it and take care of it since maintenance is an important factor for maintaining the shelf life of any tool.

The chain of your saw is most likely to fall off and get stuck in a piece of wood. It can also happen if your chainsaw gets too hot from constant use and it stretches. In such situations, one should always know how to put a chain on a chainsaw. Instead of calling a maintenance guy or getting a new one, go through the steps below and learn how to tighten the chainsaw chain.

Steps for Putting A Chain on A Chainsaw

1. Cleaning

Before proceeding with the task, you should always keep safety in mind since these objects can be very dangerous if proper care is not taken while handling them. The first thing you ought to do is put on gloves or protective gloves.

The next thing that you should do is clean the saw and the bar. There might be remnants of wood or debris on your saw and that should be cleaned off first. It can be done with the help of a paintbrush.

2. Removal of Parts

The next step would be the removal of the parts such as the nuts and the housing of the chainsaw. This can be done with the help of a ½ inch chainsaw wrench. Some manufacturers provide a wrench along with the chainsaw if yours didn’t come with one you can get one from the market as they are easily available.

With the help of this wrench, you will loosen the nuts and the bolts on the saw by twisting the wrench. Once all the nuts and bolts are safely removed, you can move on to release the tension of the bar on the chainsaw. This isn’t a difficult task too as you can very easily release the tension on the bar of the chainsaw by removing the bar nuts that are present on the saw.

Once removed, you will have relieved the tension on the bar. It is important to keep the nuts, bolts and the housing safely since you will need to put them back on once you’re done fixing the chain on the chainsaw.

3. Positioning of the Chain

This is a very important step. You need to position the chain in such a way that the teeth of the chain are facing away from you. If the teeth are facing away from you as you hold the saw, then it is in the right direction.

Next up, you have to position the chain around the sprocket. Once it is around the sprocket, you can now align it with the grooves in the bar. This way you will be doing two steps, wrapping the chain around the sprocket and then aligning it with the grooves.

And finally, pull the chain and adjust the tension on the saw. The thing with tension on a chainsaw is that it depends on the user’s preference. So, pull on it until you get the desired tension and then tighten the screws to secure the tension on your required level.

4. Cover it Up

Once the chain is fixed, you can now put the housing of the chainsaw back on with the nuts and bolts you set aside earlier. Make sure the holes in the housing are aligned with the ones on the saw and insert the nuts. Fix them with your hand if need be. You can tighten the plastic casing. It is recommended to check the tension of the chain once again before you move on with tightening the screws.

5. Check

Now that you’re done with the entire process, the last step is to try it now. Start the chain and rev it a few times, start using it on a piece of wood to check if it’s working fine. If it’s functioning smoothly then you’re good to go. If not, then you might need to check the tension again and readjust it so that it works for you.


This is a pretty simple job that you can do yourself without needing the help of any mechanic or any manual guide. Just be sure to take all the safety measures before proceeding with it.
