No matter how powerful the tool is, if the chain is not sharp then it has no value. So even if you are using a chainsaw to cut a tree, the chain needs to be sharp otherwise it will perform the poor and inefficient function, also using dull chainsaw can be dangerous to use.

Some are more durable than others but even the priciest and the high-quality chain becomes dull eventually with time. Every time you use the chainsaw it affects the sharpness of the chain and at one point you’ll have to replace the chain with a new one.

The signs for when it’s time to replace the chainsaw chain

Here are some of the warning signs that will tell you that the chain is worn out and need to be sharpened or replaced.

Inefficient cutting performance

When a chainsaw chain is sharp, it cuts through anytime easily and without any efforts. The cuts of sharp chain teeth are straight and go right through any object. However, when the chain is at the end of its lifespan then the cuts become crooked, jagged and uneven, and instead of smoothly cutting through an object you’ll find yourself putting pressure onto the tool. 

In this situation, sharpening the chain might work for a while but replacing the chain with a new one would be the best option, especially if it has been a long time since you last replaced the chain.

Difficult positioning 

This is similar to the above point. When the chain teeth are sharp, positioning a chainsaw is easier. But when it’s dull then you’ll find it hard to keep the chainsaw in proper position and you’ll feel rattling and bouncy sensation. Big safety concern comes in at this point so taking any risk is strictly unadvisable. You should replace the chain as soon as possible.

If you notice smoke

The chainsaw is manufactured for handling heavy jobs, hence any kind of friction cannot damage the tool. The performance of a chainsaw is supposed to be smooth. So if the lubrication system of the chainsaw is working properly and the chain’s tension is adjusted as well but you still notice some smoke during the cutting process then it is time to get alarmed. The smoke is a sign of dull chain teeth and ignoring it will only be dangerous for the user but it will also affect the performance of the chainsaw. The smoke is a sign that the tool is causing too much fiction and is heating up, so using such a tool can also damage the chainsaw even more. 

Damaged chain teeth

Whenever you are sharpening your chainsaw chain make sure to check out the chain’s teeth closely and look for any damaged or missing teeth. If the teeth of the chain are damaged then the chainsaw shouldn’t be used anymore until the chain is replaced because it can cause a number of potential hazards. 

If the chain teeth are sharp and in proper shape but there are few missing from between then the chainsaw can still be used but it will need a new purchase in the near future because missing teeth is also a sign that the chain is near its ending.


The lifespan of a chainsaw depends on various factors, for example, the kind of wood you are using it on or the duration of the cut plus what quality of chain you are using. All these things determine the durability of a chainsaw. Keeping the chainsaw maintained by sharpening the chain time to time can increase the amount of time a chainsaw can last. So if you feel like the chainsaw is not working as efficiently as it was in the beginning then sharpening if your best option. But if you notice any other signs that are mentioned above then replacing the chain with a new one is your best bet. Better be safe than sorry.
