What Are the Different Parts of a Chainsaw: Detailed Explanation

If you have a question about “what are the different parts of a chainsaw?” then you should read the following article. Chainsaws have many parts that work in coordination to cut through wood. The chain, the guide bar, the clutch, the saw chain brake, and the engine are the different parts of a chainsaw. All of these parts work together to make the saw operate properly. All of the parts of an electric chainsaw are critical to the function of a chainsaw.

Parts of a Chainsaw

It is important to know the terms and parts of a chainsaw before operating one. Chainsaws generally have a 2-cycle engine, a bar, a chain, and the catcher. It’s also useful for a chainsaw to have a kickstand, which allows you to lay the chainsaw down without the chain touching the ground.

Chainsaw Parts

Chainsaw parts are integral to the operation of chainsaws. Chainsaw parts include the chain, guide bar, engine, starter, throttle, fuel tank, air filter, muffler, and clutch. Chainsaw parts are made of high-strength alloys and steel. I will tell you more about them below.


This is the part of the chainsaw that regulates how much gas and air are mixed and delivered to the engine. The throttle is usually controlled with a trigger on the handle. It is important to keep the throttle in good working order to avoid over-revving the engine, which can cause damage.


This is one of the sharp parts of a chainsaw that does the actual cutting. It is made up of a series of metal links that are connected together. The chain is driven by the motor and spins around the guide bar. The teeth on the chain cut through the wood as it is fed into the saw

Throttle Interlock

This part is responsible for ensuring the chainsaw is turned off before the throttle is engaged. It is a small metal piece that is inserted into the throttle. Also known as a “safety brake.”

Bucking Spikes

This is a piece of wood that is inserted into the end of the saw to help stabilize it while cutting. It is also used to help guide the chainsaw blade when cutting.

Chain Catcher

This is a metal or plastic guard that is mounted on the bottom of the chainsaw’s guide bar. It is designed to prevent the chain from being thrown forward and hitting the operator if it breaks. It is one of the most important parts of a chainsaw chain safety, especially on large saws.

Chain Brake

This is a device that is used to stop the chain from rotating. It is usually activated by a lever or switch on the saw’s handle. Also called a chain brake lever.

Choke Valve

It is one of the inside parts of a chainsaw. This device is located near the carburetor of a chainsaw. Its purpose is to help start the saw by restricting the amount of air that goes into the engine. This makes it easier for the engine to get up to speed and start running on its own


This is a protective cover for the chain and bar on a chainsaw. It is there to protect the user from the chain if it breaks and to protect the chain and bar from damage.

Anti-Vibration System

This system is designed to reduce the amount of vibration that is transferred to the user’s hands. It consists of two metal plates that are mounted on the saw’s body and a series of springs that connect the plates to the saw’s handle. The springs allow the plates to move independently of each other, which absorbs some of the vibrations.


This is a metal or plastic cover that goes over the end of the exhaust pipe on a chainsaw. It is there to reduce the noise that the saw makes. Also, it can help to deflect some of the exhaust fumes away from the operator.

Guide Bar

This is the part of the chainsaw that actually does the cutting. The chain runs around the guide bar, providing the cutting action. It is important to choose the right size and type of guide bar for your chainsaw and the type of work you will be doing.

Chain Tensioner

This part of the chainsaw keeps the chain tight as it moves around the bar. It is located at the front of the saw near the bar. Also known as a bar adjuster.


This part of the chainsaw engages and disengages the chain from the blade. It is located near the handle of the saw.


This is the round metal disc at the end of the crankshaft. It has a series of metal teeth that mesh with the chain. As the flywheel turns, it spins the chain. Also called the sprocket.


This is the part of the chainsaw that mixes the fuel and air together before it enters the engine. It is responsible for delivering the right air/fuel mixture to the engine for combustion.

Decompression Valve

This is a small, simple valve that is used to relieve pressure in the engine before starting it. It is located on the side of the engine near the spark plug. The decompression valve is opened to release pressure in the engine before starting it. This helps to make starting the chainsaw easier.

Air Filter

This is the chainsaw part that cleans the air before it goes into the engine. It is usually made of paper or foam and is located between the carburetor and the engine. It is important to replace your air filter regularly to keep your chainsaw running properly.

Differences in Parts

I hope you have now found the answer to the question, “what are the parts of a chainsaw chain called?” Next, I will tell you about the main differences between them. Chainsaw parts are not all the same. There are slight differences among the many types of chainsaws on the market.

One of the most notable differences in the size of the bar and chain. The size of the bar and chain will vary depending on the model of the chainsaw and the intended use. For example, a saw designed for felling large trees will have a much longer bar and chain than a saw designed for general pruning.

Another difference between chainsaw models is the power source. Some chainsaws are powered by gasoline, while others are powered by electricity. There are also some models that are powered by batteries.
The type of power source will usually dictate the size and weight of the saw. Gasoline-powered chainsaws are typically the heaviest and most powerful, while electric chainsaws are usually the lightest and least powerful.

The final major difference between chainsaws is the type of chain. There are two main types of chains, standard, and chisel. Standard chains are the most common and are designed for general use. Chisel chains are designed for cutting through hard, dense materials like concrete and metal.


What is the part that turns the chain on a chainsaw?

The part that turns the chain on a chainsaw is called the flywheel. It is located at the top of the chainsaw and is connected to the chain. When the chainsaw is turned on, the flywheel spins and turns the chain.

What is the sharp part of a chainsaw called?

The sharp part of a chainsaw is called the chain. It is a metal chain with sharp teeth that are used to cut through wood. The chain is typically made of carbon steel or stainless steel.

How many parts are in a chainsaw?

Depending on the model, a chainsaw can have anywhere from 20 to over 100 parts. It is a complex piece of machinery with many different moving parts. This makes it difficult to give a definitive answer.

Finally, I hope this guide helped you find the best chainsaw chain for your needs. Chainsaw parts are a necessary part of owning a chainsaw. You don’t need to know all of them to be able to operate a chainsaw safely and efficiently, but it’s good to have a basic understanding of how your saw works. The most important part of the chainsaw is the chain. If the chain is not properly maintained, the chainsaw will not work properly.
