Do Chainsaw Chains Stretch?

As a homeowner, it’s important to understand the basics of chainsaw maintenance and use. While they may seem intimidating, chainsaws are actually relatively simple machines that require regular upkeep and attention.

One common question is whether or not chainsaw chains stretch; the answer is yes. Let’s take a look at why that is and what you can do about it.

What Causes Chainsaw Chain Stretch?

Chainsaw chain stretch occurs due to the vibration of the saw as well as the heat generated during cutting.

Over time, the heat and vibrations cause the steel links in the chain to become loose and move farther apart from one another. Dirt, debris, and rust can also accumulate on the chain links, further contributing to their loosening over time.

It’s natural for chainsaws to stretch if they are used frequently, so it’s important to check the chain tension regularly and adjust it as needed. Over extended periods of time, the friction generated from sawing through wood can cause a chainsaw chain to stretch.

If your chainsaw chain has stretched significantly, you may want to consider replacing it with a new one. This will help ensure that your chainsaw is working like it should and that you are safely cutting through wood without any risk of the chain coming loose or breaking.

How Can I Tell if My Chain Needs to be Adjusted?

If your chainsaw vibrates more than usual when running or cuts slower than normal even with a sharp blade, that could be an indication that your chain needs to be adjusted or replaced.

You should also inspect your chain regularly for signs of rust or wear and tear; if you notice any of these issues, it’s probably time for an adjustment or replacement. 

Another way to determine if your chain needs adjusting is to measure its length before and after use; if it has stretched significantly, then you need to adjust it accordingly.

To properly adjust a chainsaw chain, you will need a special tool called a ‘chain tensioner‘ – these tools typically come with new chainsaws but can also be purchased separately. The chain tensioner will help you tighten the chain so that it runs smoothly without excess vibration or stretching.

Conclusion

Chainsaw chains do indeed stretch due to normal wear and tear over time as well as exposure to dirt and debris during operation.

If you notice any abnormal vibrations coming from your saw or slower-than-normal cutting speeds despite having a sharp blade installed, those could be signs that your chain needs adjustment or replacement.

To properly adjust a chainsaw chain requires a special tool called a tensioner; these can typically be purchased at hardware stores alongside other supplies necessary for proper maintenance of your saw.

With regular inspection and care, keeping your saw in good working order shouldn’t be too much of an issue.
