What Causes Chainsaw Chains to Stretch?

There are several reasons why chainsaw chains stretch. Here are the most common ones:

  1. Normal Wear and Tear

One of the main causes of chainsaw chain stretching is normal wear and tear. When you use your chainsaw, the chain runs over the guide bar at a high speed, which can cause the chain to stretch over time. This stretching is a natural part of the chainsaw’s life cycle, and it’s important to keep an eye on the chain tension to ensure that it’s not too loose.

  1. Overheating

Overheating can also cause chainsaw chains to stretch. When you use your chainsaw for an extended period of time, the heat generated by the chain can cause the metal to expand and the chain to stretch. This is especially true if you are using a chainsaw with a smaller engine, as the chain will have to work harder to cut through wood.

  1. Improper Maintenance

Improper maintenance can also contribute to chainsaw chain stretching. If you don’t keep your chainsaw clean and lubricated, the chain can become damaged and begin to stretch. Additionally, if you don’t regularly check the chain tension and adjust it as needed, the chain can become too loose and stretch over time.

How to Prevent Chainsaw Chains from Stretching

Now that we know the causes of chainsaw chain stretching, let’s look at some tips for preventing it from happening:

  1. Keep Your Chainsaw Clean and Lubricated

Regularly cleaning and lubricating your chainsaw can help prevent chain stretching. When you use your chainsaw, dirt, sawdust, and other debris can get trapped in the chain, which can cause it to become damaged and stretch over time. By keeping your chainsaw clean and lubricated, you can help prevent this from happening.

  1. Check the Chain Tension Regularly

Checking the chain tension regularly is essential for preventing chain stretching. If the chain is too loose, it will cause the chain to stretch over time. If the chain is too tight, it can cause the chain to break. To check the chain tension, turn off the chainsaw and use a screwdriver to adjust the tension until the chain is snug against the guide bar.

  1. Use the Right Chainsaw for the Job

Using the right chainsaw for the job can also help prevent chain stretching. If you are cutting through thicker wood, you will need a chainsaw with a larger engine and a longer guide bar. If you are cutting through thinner wood, a smaller chainsaw will be sufficient. Using the right chainsaw for the job will ensure that the chain is not working too hard and will help prevent stretching.

  1. Replace the Chain When Necessary

Finally, replacing the chain when necessary can help prevent stretching. Over time, chainsaw chains will become worn and damaged, which can cause them to stretch. If you notice that your chain is damaged or has become too loose, it’s important to replace it as soon as possible to prevent further damage.

Final Thoughts

Chainsaw chain stretching is a common problem that can be caused by normal wear and tear, overheating, and improper maintenance. By keeping your chainsaw clean and lubricated, checking the chain tension regularly, using the right chainsaw for the job
