This article is going to teach you how to perfect your chainsaw skills. It will also teach you what the most essential parts of a chainsaw are, as well as some safety tips.

The “chainsaw safety parts” are essential for anyone who wants to use a chainsaw. The most important part is the chain and bar. The other parts that you should have on hand include the spark plug, air filter, clutch cover, oil pan, and muffler.

Chainsaws are relatively complex machines that use a variety of parts to function. A gasoline engine requires several key components to stay running,Chainsaw Parts and when any of these parts fail, you have a broken tool on your hands. If you checked your fuel and oil levels and everything seems fine, it’s time to fine tune your diagnostics to figure out exactly what is wrong. The first step in pinpointing the problem is to learn about the different parts of a chainsaw and what they do. When you understand the fundamentals of each part, you can better understand what may have failed. Let’s take a look at the different kinds of chainsaw parts.

Fly Wheel

When the engine is turned on, the fly wheel turns, controlling the engine’s speed. This enables a smooth and vibration-free functioning. The flywheel also includes little blades on the side that function as fans, cooling the engine. Your flywheel may have been broken or chipped if your tool is vibrating excessively or spinning at high rates.


The throttle controls the amount of gasoline delivered to the engine’s cylinders. The user may regulate the chain speed during operation by using the throttle. The engine revs to its maximum RPM when fully squeezed. When the throttle is depressed, the chain stops moving and the engine idles. The engine will rev rapidly if the throttle is stuck. A faulty throttle will prevent gasoline from reaching the cylinders, leaving the chain immobile.

Interlocking Throttle

Chainsaw parts are often designed with safety in mind, as in the case of the Interlocking Throttle. This safety feature only allows the throttle to engage when the button is pressed. The Interlocking Throttle is located on the grip portion of the handle. To operate and start the saw, this button must be pressed first.


A chainsaw clutch, like a car’s clutch, links the engine to the “drive shaft,” or chain. The clutch does not engage at moderate speeds, such as while the car is idling. The clutch interacts with the chain as the throttle is opened and the engine speed rises. Centrifugal force is used to operate this chainsaw component. The drive is engaged by the inertia of high-speed spinning.

Brake Chain

In 1995 the Brake Chain became one of the essential chainsaw parts due to safety concerns. This device quickly stops the chain in the event of kickback. Kickback happens when the chainsaw comes across a particularly rough area, causing the chain to get caught and release quickly. Oftentimes the tool pops up in the direction of the operator. The Brake Chain stops the chain quickly to minimize injury.

Valve for Decompression

After each use of a chainsaw, the pistons are often left compressed. A chainsaw left in this state can be exceptionally difficult to start. A Valve for Decompression releases this pressure to allow for easier starting. These types of convenience-oriented chainsaw parts make operating these tools much easier.

Hand Protection

Kickback can also be dangerous to the hands. The Hand Protection protects the operators hands during the event of kickback. It consists of a plastic shield that is mounted between the handle and the blade. Users should always hold the chainsaw at the designated handles.


While chainsaws seem to be noisy machines, without the addition of a muffler, they would be much louder. The muffler is where burnt fuel and air escape the machine at the very end of the combustion phase. Sound waves are muffled before leaving the operator’s ears, thereby decreasing noise and ear damage.

Handle with Anti-Vibration Technology

Chainsaws create an exceptional amount of unseen vibration which can reverberate through the user’s body. This vibration can be damaging to the hands and arms over time. Ergonomics can be improved with the addition of an Handle with Anti-Vibration Technology. This reduces the amount of vibration entering the body resulting in a more comfortable experience.

The “parts of a chainsaw bar” is an essential part for any chainsaw. It can be found in the home section at your local hardware store.
