When Should You Throw Away a Chainsaw Chain?

You may have wondered at some point whether or not you should replace the chain on your chainsaw. The performance and safety of your chainsaw will greatly depend on the condition of the chain. 

What Is the Average Lifespan of a Chainsaw Chain?

There is no predetermined timeline or expiration date for a chainsaw chain; its life expectancy is determined by its use and maintenance. Chainsaw chains can last for more than five years when used frequently. Chainsaw chains can last for decades when used infrequently.

Signs That Indicate the Need for a New Chain

With time, the chain will lose its sharpness, which will make the work more challenging and possibly dangerous. Listed below are some of the telltale signs that the chain will soon be too dull to perform the job effectively.


  1. During the sawing process, you need to apply more pressure to the wood than usual; to do the job, the saw chain needs to pull into the wood.
  2. Rather than rough threads, the chain creates fine sawdust; it appears more like sanding than cutting.
  3. As you cut, the chainsaw rattles, making it difficult to achieve precise cutting positions.
  4. Despite being properly lubricated, the chainsaw smokes
  5. A chainsaw that pulls in one direction normally results in crooked cuts. This is usually caused by blunt-cutting teeth on one side and uneven tooth lengths.
  6. If the teeth of the chain have been damaged by rocks or dirt, the chain will have to be replaced.


If you are considering whether or not to replace your chainsaw chain, these are the six main factors to consider. As mentioned at the beginning of this post, a chainsaw chain usually lasts for many hundreds of hours.


As long as you maintain your equipment properly, a chainsaw may last for several decades, depending on how often you use it and how well you maintain it.
