Should a Chainsaw Smoke When Cutting? (Know the Reason)

If you are a beginner you might probably wonder one thing: should a chainsaw smoke when cutting?

No, a chainsaw shouldn’t smoke too much when cutting. However, it happens only when the bar oil is not reaching the chain bar or it is running low. As a result, smoke is produced due to excessive heating due to friction.

This is not only bad for the saw but also for your health. So, if you see that your chainsaw is smoking excessively, then you should stop using it and check the bar oil level.

Having that said, there might be some other issues too that can cause excessive smoking. Luckily you have landed in the right place because I have mentioned everything you need to know.

So if you are interested in learning about the reasons why a chainsaw produces smoke and its solution then keep on reading.

Should a Chainsaw Smoke When Cutting?

As mentioned earlier, a chainsaw shouldn’t produce too much smoke while cutting. But if it is then there might be some serious issues with it. So, in this section, I will be discussing the reasons due to why a chainsaw produces smoke and its solution.

The Bar Oil Is Not Reaching The Chain

If the bar oil is not reaching the chain then it will start to produce smoke. Because when the oil is not reaching the chain then it will cause excessive friction between the metal parts which will eventually lead to smoke.

So, if you see that your chainsaw is smoking then the first thing you should check is the bar oil level. If it is low then you should fill it up. And if it is empty then you should check the oil pump.

Because if the oil pump is not working then the bar oil will not reach the chain. As a result, your chainsaw will start to produce smoke.

Black Exhaust Smoke Due To Wrong Fuel To Oil Ratio

If you are a beginner and this is your first time using a chainsaw then it is possible that you are using the wrong fuel to oil ratio. Because if you use the wrong fuel to oil ratio then it will lead to black exhaust smoke.

According to the Stihl USA, the best fuel to oil ratio is 1:50 oil to gas. Exceeding this ratio and adding excessive oil will eventually lead to smoking.

The Chain is Worn Out

Another reason which can lead to excessive smoking is a worn-out chain. Because if the chain is worn out then it will also cause excessive friction between the metal parts which will eventually lead to smoke.

So, if you see that your chainsaw is smoking then you should check the chain. And if you see that it is worn out then you should replace it with a new one.

Other Factors That Can Cause Chainsaw to Smoke

When it comes to chainsaws, there are a lot of different factors that can affect how much they smoke. For example, if the chain is dull, it will cause more friction and therefore produce more smoke.

Similarly, if the bar oil is old or low, this can also contribute to more smoke. In general, if the chainsaw isn’t properly lubricated or maintained, it is more likely to produce more smoke.

Besides that, smoke can also be due to less or no maintenance of the tool. You see most of the time woodworkers are too busy and they just use their tools one after another and then store them after when they are done using them.

The best thing is to always clean the tools before storing them, especially power saws. It is because the dust and dirt caught in the filters of these power saws can lead to blockage and hence it will result in overheating.

Moreover, clogged filters will also restrict airflow and this will lead to chainsaw smoking. So, these were some of the reasons why a chainsaw produces smoke.

Chainsaw Engine Is Smoking And Overheating

Even though most of the time the smoke is caused due to the above-mentioned reasons. However, it is possible that it is caused by something else. For example, if the chainsaw engine is smoking then it might be due to a problem with the piston or rings.

In this case, you will need to take the chainsaw to a mechanic and get it fixed. However, if the chainsaw is smoking and overheating then it is most likely due to a problem with the carburetor.

In this case, you will need to clean the carburetor. And if that doesn’t solve the problem then you will need to replace it.

How Do You Tell If A Chainsaw Is Overheating?

Heating is a normal process in almost all power tools. This is because different parts are working at different speeds and there is a lot of friction going on. But the problem is how do you tell if the chainsaw is overheating.

The best way to tell if a chainsaw is overheating is by touch. If you see that the chainsaw is too hot to touch then it is most likely overheating. Another way to tell if a chainsaw is overheating is by the smell.

If you see that the chainsaw is producing a burning smell then it is most likely overheating. In this case, you should stop using the chainsaw and let it cool down.

Moreover, if you see that the chainsaw is smoking then it is also a sign that it is overheating. So, these were some of the ways by which you can tell if a chainsaw is overheating.

Why Is My Chainsaw Blade Burning The Wood?

If you see that the chainsaw blade is burning the wood then it is most likely due to poor lubrication. Since the chainsaw chain is the hardest working part, therefore, it needs to be properly lubricated.

Lubrication allows different parts of the saw to move smoothly and it also prevents excessive friction. If the saw is not properly lubricated then it will cause the chain to bind and this can lead to kickback.

Moreover, if the chain is not adequately lubricated then it will also cause the blade to heat up and this can eventually lead to the burning of the wood. So, if you see that the chainsaw blade is burning the wood then you should check the lubrication.

How Do You Stop A Chainsaw From Smoking?

As we mentioned before that smoke is mostly caused due to poor lubrication or maintenance. Therefore, the best way to stop a chainsaw from smoking is by properly lubricating it and maintaining it.

Make sure to always clean the saw parts whenever you use it and never store it directly after use. Let it rest and cool down for a while. Also, make sure to change the filters of the saw every once in a while.

It is because they get clogged after excessive use due to dirt and dust. Clogged filters are dangerous for the engine as it prevents airflow causing overheating and smoking.

If you see that the chainsaw is smoking, you should stop using it and let it cool down. Besides that, you must always use a proper oil mix ratio otherwise you will get into trouble.

These were some of the ways by which you can stop a chainsaw from smoking.

Safety Measures To Keep in Mind While Working with a Chainsaw

Chainsaws are one of the most powerful and dangerous tools. Therefore, it is extremely important to take all the necessary safety measures while working with them.

The first and most important safety measure is to wear proper safety gear. This includes gloves, goggles, earplugs, and boots. It is also extremely important to wear a mask while working with a chainsaw.

Another safety measure is to always keep the saw in good condition. This means that you should regularly clean and lubricate it. Moreover, you should also sharpen the chain whenever necessary.

Another safety measure is to be extra careful while working with the saw. This means that you should never try to cut through anything that is too thick or too hard. Moreover, you should also never try to force the saw.

If you do so then it can easily lead to an accident. So, these were some of the safety measures that you should keep in mind while working with a chainsaw.

The Bottom Line

Smoke coming out of a chainsaw is mostly due to poor lubrication or maintenance. Therefore, the best way to stop smoking is by properly lubricating it and maintaining it.

Always clean the saw parts whenever you use it and never store it directly after use. Also, make sure to change the filters of the saw every once in a while. If you see that the chainsaw is smoking, you should stop using it and let it cool down.

Besides that, you must always use a proper oil mix ratio otherwise you will get into trouble.
