How to install the chain on a garden chainsaw correctly?

Aug 27, 2025

Hey there, fellow garden enthusiasts! As a supplier of top - notch garden chainsaws, I've seen it all when it comes to chainsaw usage and maintenance. One of the most common questions I get from customers is how to install the chain on a garden chainsaw correctly. In this blog, I'll walk you through the process step by step.

First things first, safety should always be your number one priority. Before you even start thinking about installing the chain, make sure the chainsaw is turned off and unplugged if it's an electric model, or the fuel valve is closed if it's a gas - powered one. Also, wear protective gear like gloves and safety glasses. You don't want any unpleasant surprises!

Let's start by gathering the tools you'll need. You'll typically need a wrench, which usually comes with the chainsaw. Some modern chainsaws also have a tool - less chain tensioning system, but having a wrench on hand is still a good idea.

Now, let's talk about the chain itself. If you're in the market for a new chain, we've got some great options. Check out our Small Rechargeable Chainsaw and Electric Lithuim Chain Saw. These are perfect for light to medium - duty garden work. And of course, our Garden Chainsaw is a beast for more heavy - duty tasks.

Okay, back to the installation process. The first step is to locate the chain cover. On most garden chainsaws, the chain cover is located on the side of the saw. Use your wrench to loosen the bolts or nuts that hold the cover in place. Don't remove them completely, just loosen them enough so you can take the cover off.

Once the cover is off, you'll see the bar and the sprocket. The bar is the long, flat part that the chain runs on, and the sprocket is the toothed wheel that drives the chain. Before you install the new chain, take a close look at the bar and sprocket. Make sure there's no debris or damage. If there's any dirt or sawdust, use a brush to clean it off.

Now, it's time to install the chain. Start by placing the chain around the sprocket. Make sure the teeth of the chain are facing the right direction. Most chains have an arrow or some other indicator that shows the direction of rotation. Align the chain so that the arrow points in the direction that the chain will move when the saw is running.

Next, drape the chain over the bar. The chain should fit snugly into the groove on the bar. Make sure the chain is evenly distributed along the bar and that there are no kinks or twists.

Once the chain is in place, it's time to adjust the tension. This is a crucial step. If the chain is too loose, it can come off the bar while you're using the saw, which is extremely dangerous. If it's too tight, it can cause excessive wear on the chain and the saw.

To adjust the tension, look for the chain tensioning screw. On some chainsaws, it's located near the chain cover. Use your wrench to turn the screw clockwise to tighten the chain or counter - clockwise to loosen it. As you turn the screw, keep an eye on the chain. You should be able to move the chain slightly by hand, but it shouldn't sag too much.

A good way to check the tension is to lift the chain off the bar slightly in the middle. There should be about 1/4 to 1/2 inch of slack. If it's too tight or too loose, keep adjusting the screw until you get the right tension.

After you've adjusted the tension, put the chain cover back on. Tighten the bolts or nuts, but don't over - tighten them. You want the cover to be secure, but you don't want to damage the threads or the cover itself.

Now, give the chain a final inspection. Make sure it's properly seated on the sprocket and the bar, and that the tension is correct. Before you start using the saw, give the chain a few turns by hand to make sure it moves smoothly.
