Can you put a smaller blade on a chainsaw?

Sure, go ahead and put a smaller blade on a chainsaw and watch your lumber dreams shatter.

No, putting a smaller blade on a chainsaw is not recommended. Chainsaws are designed to work with specific blade sizes to ensure optimal cutting performance and safety. Altering the blade size can compromise the tool’s effectiveness and potentially lead to accidents or damage to the chainsaw.

This article will explore whether putting a smaller blade on a chainsaw is possible.

So Let’s Get Started!

How can you put a Smaller Blade on a Chainsaw?

Today we will show you how to put a smaller blade on a chainsaw. This is a great way to save money and get the job done.

First, you’ll need to find a smaller chain. You can do this by measuring the bar on your chainsaw and finding a two sizes smaller chain. For example, if your bar is 16 inches long, you’ll need a 14-inch chain.

Once you have the correct size chain, follow these steps:

1. Remove the old chain from the saw. To do this, first, loosen the tensioner knob or lever. Then, slide the old chain off of the bar.

2. Put the new chain around the bar. Start at the bottom of the bar and feed the new chain through all the guide holes.

3. Once the new chain is in place, tighten the tensioner knob or lever until it’s snug against the new chain. Be sure not to over-tighten, as this can damage the saw and the new chain.

4. Test-run the saw to ensure everything is installed correctly and working properly.

That’s all there is to it! You can save money with simple steps and put a smaller blade on your chainsaw.

What Tools Do You Need to Change the Blade?

Assuming you have a standard-size chainsaw, you will need the following tools to change the blade: 

  • A Phillips screwdriver 
  • An adjustable wrench 
  • A bar clamp or vise 
  • A file 
  • Safety goggles 
  • Gloves 

First, make sure your chainsaw is turned off and unplugged. Then, use the Phillips screwdriver to remove the two screws holding the bar cover. Once the cover is off, you can see the blade. Use the adjustable wrench to loosen the nut that secures the blade in place. Be careful not to drop the blade when removing it. 

Next, line the new blade up with the old one. Make sure all of the teeth are pointing in the same direction. Securely tighten the nut with the adjustable wrench. Replace the bar cover and screws. Turn on your chainsaw and test it out!

Advantages and Disadvantages of Using a Smaller Blade

A smaller blade on a chainsaw has both advantages and disadvantages. One advantage is that it requires less power, making it more fuel-efficient. 

Additionally, a smaller blade causes less vibration, benefiting users who experience hand fatigue. 

On the other hand, a smaller blade may not be able to cut through large branches as easily as a larger one. Ultimately, the best blade size for a chainsaw depends on the user’s specific needs. 


  • Requires less power, making it more fuel-efficient
  • Causes less vibration, reducing hand fatigue


  • It may not be able to cut through large branches as easily  as a larger blade

Safety Measures to Take When Changing the Blades

When changing the blades on a chainsaw, always take safety precautions. First, disconnect the saw from its power source. Then, use a wrench to remove the old blade. Be careful not to touch the teeth of the blade, as they are sharp. 

Once the old blade is removed, carefully install the new edge. Ensure the new blade is securely placed before reconnecting the saw to its power source. 

In addition, always wear protective gear when working with a chainsaw. Wear safety glasses, gloves, and hearing protection to protect yourself from injury. 

Finally, read the instruction manual that came with your saw and follow all safety instructions for the use and maintenance of the saw.


In conclusion, it is possible to put a smaller blade on a chainsaw as long as the size of the bar and chain match up with the saw. The difference in cutting capacity may be negligible, but depending on what you need to cut, this could make all the difference. Remember that if you use a small blade on your chainsaw, it’s important to take safety precautions and properly maintain your saw for optimal performance.


Can You Change The Blade Size On A Chainsaw?

Can you change the blade size on a chainsaw? While changing the blade size on a chainsaw may be technically possible, it is not recommended. Chainsaws are designed to work with specific blade sizes that are carefully calibrated for optimal performance and safety. Altering the blade size can negatively affect the balance, cutting ability, and overall functionality of the chainsaw. It can also void the warranty and increase the risk of accidents or damage.

What Is The Benefit Of A Shorter Chainsaw Bar?

What is the benefit of a shorter chainsaw bar? A shorter chainsaw bar offers a few advantages. It is lighter and easier to manoeuvre, making it ideal for tasks that require more precision and control. Additionally, a shorter bar reduces the risk of kickback, a sudden upward or backward motion of the chainsaw, enhancing user safety. However, it also limits the maximum diameter of the wood that can be cut.

Can You Put Any Bar On Any Chainsaw?

Can you put any bar on any chainsaw? No, you cannot put any bar on any chainsaw. Chainsaws are designed to accommodate specific bar sizes and types compatible with their engine power, chain pitch, and other specifications. Using an incompatible bar can result in poor performance, increased wear on the chainsaw, and potential safety hazards. Always consult the manufacturer’s guidelines to ensure the proper bar is used for your chainsaw model.
