Every chainsaw is unique in some way. Especially when you’re separating the smallest component possible, the internal structure may not look the way you imagined.
Even when you are looking at components from the same brand, there can be significant differences between them.
The Stihl chainsaw parts diagram includes a lot of components, namely the air filter, bar guard, bar nut, spring clip, clutch assembly, fuel line, worm gear, sprocket bearing, fuel filter, starter handle, etc. These are the most commonly replaced component, which can vary depending on the model you have.
Parts Of A Stihl Chainsaw
The basic components of a chainsaw are similar for all brands and models. Those components are what make a tool chainsaw. For instance, there will be an engine, a handle, hand guards, fuel tank, air filter, bar, chain, etc.
The most important part of a chainsaw is the chain itself. It stays wrapped around the bar, which makes the chainsaw a functional tool. If your existing chain is damaged, you can consider the following replacement parts:
|Anzac 16-Inch Chainsaw Chain Replacement||Resists wear.
Compatible with Stihl.
|ATMTV R55 Chainsaw Chain||Anti-fracture material.
Stronger rivet connections.
The bar is a piece of metal that supports the chain. It provides stability and helps the chain cut through materials.
3. Hand Guard
The hand guard works as a barrier and prevents your hand from slipping into the chain. There can be multiple hand guards depending on the model you have.
Much like any other noisy tool, the chainsaw comes with a muffler too. It ensures that the noise is reduced.
5. Chain Brake
The chain brake is for quickly stopping the chainsaw. It’s easily accessible, and the chain stops spinning when the brake is used.
The engine of your chainsaw receives the fuel and makes the chainsaw run.
7. Air Filter
Air filter is in charge of stopping unnecessary debris from getting inside the chainsaw.
8. Fuel Tank
The fuel tank stores the gas and delivers it to the engine when the chainsaw starts running.
9. Trigger And Throttle
Both of them are for turning the chainsaw on. Because the power tool is dangerous to use, two different options are required to turn the machine on. It reduces the chance of accidentally turning on the chainsaw.
10. Lubricant Tank
The lubricant tank stores the oil required for the chainsaw. It can facilitate running the chain and the bar.
A chainsaw carburetor plays an important role in running the chainsaw smoothly. It ensures a proper mixture of fuel and air, depending on how you’re operating the chainsaw.
