The Stihl chainsaw is a type of portable chainsaw that is used for cutting wood and other materials. The Stihl brand is known for its durability and reliability, which are some of the reasons why its chainsaws are popular among professional and recreational users alike.
In this article, we’ll show the Stihl chainsaw parts diagram and explain the functions of each part.

Stihl Chainsaw Parts Explained
The carburetor is a device that mixes air and fuel in the correct ratio for the engine to run efficiently. It is responsible for regulating the amount of fuel and air entering the engine, and is typically adjustable to accommodate different operating conditions and fuel types. The carburetor plays a crucial role in the performance and efficiency of the chainsaw.
Spark plug boot
The spark plug boot on a Stihl chainsaw is a rubber or silicone cap that covers and protects the spark plug wire and spark plug itself. It helps prevent damage to the wire and plug, as well as prevents debris and moisture from entering and disrupting the spark. It also helps ensure a proper electrical connection between the wire and spark plug.
Handle heating switch
The handle heating switch on your Stihl chainsaw is a feature that allows the operator to turn on the heating element in the handle of the chainsaw to provide warmth and improved grip in cold weather conditions. This can help to reduce hand fatigue and improve the overall performance of the chainsaw in colder temperatures.
The chain sprocket is a small, toothed wheel that is attached to the chainsaw’s engine and drives the chain. The sprocket rotates as the engine runs, pulling the chain around the guide bar and allowing the chainsaw to cut through wood.
It is an essential part of the chainsaw’s drive system and must be properly maintained and replaced if worn or damaged to ensure smooth and efficient cutting performance.
The chain brake is a safety feature that activates when the front hand guard is pushed forward, halting the movement of the chain. This helps to prevent accidental cuts and injuries. It can also be manually activated by pulling the chain brake lever.
The chain tensioner on a Stihl chainsaw is a mechanism that adjusts the tension of the chain on the bar to ensure that it is tight enough to cut properly, but not so tight that it causes excessive wear on the chain or the bar.
It is typically located on the side of the chainsaw and consists of a spring-loaded arm that is used to adjust the tension of the chain. The tensioner is an essential part of the chainsaw and should be checked regularly to ensure that it is functioning properly.
The bumper spike is a small, pointed protrusion located at the base of the chainsaw’s guide bar. It helps to guide the chainsaw along the cutting surface and prevent the chainsaw from bouncing or skipping when cutting. It also helps to protect the chainsaw’s guide bar and chain from damage.
The guide bar is the metal bar that the chain runs around. It is the part of the chainsaw that extends out from the body of the saw and comes into contact with the wood being cut.
The guide bar is typically made of high-strength steel and is designed to withstand the forces exerted by the chain as it cuts through wood. The length of the guide bar determines the maximum size of wood that the chainsaw can cut, with longer guide bars allowing for the cutting of larger logs.
Oil filter cap
The oil filter cap on a Stihl chainsaw is a small metal or plastic cap that covers the oil filter, which is a component that helps to clean and lubricate the engine. The oil filter cap is typically located on the side of the chainsaw’s engine and can be easily removed for maintenance and replacement of the oil filter.
The muffler on your Stihl chainsaw is a device that reduces the noise produced by the engine by directing the exhaust gases through a series of channels and chambers, which absorb and dissipate the sound waves. This helps to reduce the noise levels and ensure that the chainsaw can be used safely and comfortably in a variety of different environments.
The decompression valve on a Stihl chainsaw is a small, spring-loaded valve located near the spark plug. When activated, the valve allows excess pressure to be released from the engine, making it easier to pull the starter cord and start the chainsaw. This can be useful for cold starts or when the chainsaw has been flooded with fuel.
The Starter grip is a handle located near the front of the chainsaw that is used to start the engine. It is typically a black or gray rubber handle that is located near the front of the chainsaw and is used to grip and pull the starter rope. This handle is essential for starting the chainsaw and is designed to provide a comfortable and secure grip while starting the engine.
Fuel filter cap
The fuel filter cap on a Stihl chainsaw is a component that covers and protects the fuel filter, which is responsible for removing impurities and debris from the fuel before it enters the engine. The fuel filter cap is typically located near the fuel tank and is removed for cleaning or replacement of the fuel filter.
Master Control lever
The Master Control lever on the Stihl chainsaw is a lever that controls the power output of the chainsaw’s engine. It is typically located on the right side of the chainsaw, near the handle, and is used to adjust the chainsaw’s power output for different cutting tasks.
When the lever is in the “ON” position, the chainsaw’s engine will be running at full power. When the lever is in the “Choke” position, the engine will be running at a reduced power output, which is useful for starting the chainsaw or for making fine cuts.
