Step 1 Remove Bar and Chain From Chainsaw
The first step is removing the side plate so that you can remove the bar and chain. Generally, chainsaws will have two or more nuts holding your plate in place.
Use a wrench to unscrew the nuts, so that you can easily access the plate to get to the chain.
You will find that some brands of chainsaws have a break that is attached to the side plate if your chainsaw has this, unlock the brake before you try to remove the plate. If you skip this step, you could have a hard to impossible time to reinstall.
Step 2 Loosen The Chain
Once you get your first step tackled, you will want to loosen your blade so that you can pull it off from your chainsaw. You can do this by pulling the nose of the chainsaw bar away from the chainsaw. This is going to release the blade from the tensioner. Make sure that you are taking safety steps to avoid unnecessary cuts or damage your chainsaw. For additional safety guidelines check out Florida trail associations chainsaw training program.
If your chainsaw has a buildup of sawdust, make sure to clean this up before you go and put the new blade on your chainsaw.

Step 5 Replace With New Or Sharpened Blade
Now you are ready to thread on a new chain or a freshly sharpened chain. Start by placing your chain around the clutch drum (ensuring the drink links for sure engage with the sprocket). Then work your way up to the nose (front tip) of the chainsaw.
During this step, you want to make sure your chain is aligned correctly, and you work on tightening up the tension as you start to get your chain in place. Use your saw’s adjustment pin when you are pulling on the chain wrapping it around your bar.
Step 6 Place Side Bar In Place
Once you fully get your blade on successfully now is the time to place the side plate again. Screw in the nuts, make sure not to go too tight, so the chain can move while you work on adjusting.
Now you want to work on tightening the chain with the tensioning screw that you loosened earlier. Once you finish, you are ready to go cutting!
