As an experienced arborist, I have used a variety of chainsaws in my line of work. However, I always find myself reaching for my trusty Stihl 021 due to its perfect balance between power and maneuverability. One crucial factor that contributes to its efficiency is the appropriate chain size.

The Stihl 021 is designed to use a specific chain size, typically 3/8 inch pitch with a gauge of .050 inches. This may seem like a small detail, but it plays a significant role in the overall performance of the chainsaw. The chain size directly impacts the cutting speed and accuracy of the saw. A larger chain may provide more power but at the cost of increased weight and reduced maneuverability. On the other hand, a smaller chain may allow for better maneuvering but can lack the necessary power for certain tasks.

Moreover, using the correct chain size ensures safety while operating the chainsaw. A mismatched or improperly sized chain can lead to kickback or binding, which can be hazardous for both the user and those around them. The Stihl 021’s recommended chain size has been carefully determined by its manufacturers to optimize its performance while prioritizing safety.

In conclusion, opting for the recommended chain size for your Stihl

My Buying Guide on ‘Stihl 021 Chain Size’

As a proud owner of a Stihl 021 chainsaw, I understand the importance of finding the right chain size for optimal performance. After conducting thorough research and consulting with experts, I have compiled this buying guide to help you make an informed decision when it comes to purchasing a chain for your Stihl 021.

Understanding the Stihl 021 Chain Size

The Stihl 021 chainsaw uses a specific chain size to ensure efficient cutting and longevity of the saw. The chain size is determined by three important measurements: pitch, gauge, and number of drive links.

Pitch: This refers to the distance between three consecutive rivets in the chain. The pitch for Stihl 021 chainsaws is typically 3/8 inch.

Gauge: This is the thickness of the drive links on the chain. The gauge for Stihl 021 chainsaws is usually .050 inches.

Number of Drive Links: This refers to the number of links on one side of the chain that engage with the sprocket. The number of drive links for Stihl 021 chainsaws can range from 50-62 depending on your specific model.

Finding the Right Chain Size

In order to find the correct chain size for your Stihl 021, you will need to know your saw’s model number and bar length. You can find this information on your saw’s bar or in its user manual.

The most important thing to remember when choosing a chain size is that it must match all three measurements (pitch, gauge, and number of drive links) exactly. Using an incorrect size can result in poor cutting performance, increased wear on your saw, and potential safety hazards.

Purchasing Options

When shopping for a new chain for your Stihl 021, you have two options: purchasing from a dealer or buying online.

Dealer: Visiting a local dealer is often recommended as they have knowledgeable staff who can help you find the correct chain size and offer additional advice or maintenance services if needed. However, purchasing from a dealer may be more expensive than buying online.

Online: Buying online can be convenient as you can easily compare prices and have a wider range of options to choose from. Just make sure to purchase from a reputable seller and double-check that you are buying the correct chain size before making your purchase.

Maintenance Tips

To ensure optimal performance and longevity of your chainsaw, it’s important to properly maintain your chainsaw and its chain. Here are some tips:

  • Clean debris off your chainsaw after each use.
  • Tighten loose bolts or screws regularly.
  • Keep an eye on the tension of your chain while in use – it should not be too loose or too tight.
  • Regularly sharpen or replace dull or damaged chains as needed.
  • Lubricate your saw’s bar and sprocket regularly according to manufacturer guidelines.

In Conclusion

The right chain size is crucial for ensuring optimal performance and safety when using a Stihl 021 chainsaw. By understanding how pitch, gauge, and number of drive links affect chain size, as well as properly maintaining your saw and its parts, you can confidently choose the right chain for your needs. Whether purchasing from a dealer or online, always double-check that you are buying the correct size before making your purchase. Happy cutting!
