Measuring the chain on a chainsaw is a crucial step in ensuring optimal performance and safety. An incorrectly sized chain can lead to premature wear, reduced cutting efficiency, and potential safety hazards.
The length of a chainsaw chain is determined by the length of the guide bar. Matching the chain length to the guide bar ensures proper tension and prevents the chain from becoming too loose or too tight. A properly tensioned chain will cut smoothly and efficiently, while an incorrectly tensioned chain can cause the chainsaw to bind or kickback.
Measuring the chain on a chainsaw is a straightforward process that can be completed in a few simple steps. Here’s a comprehensive guide on how to measure a chainsaw chain:
1. Length
The length of the chainsaw chain is a crucial factor in ensuring proper tension, which is essential for optimal performance and safety. When the chain is the correct length for the guide bar, it can be properly tensioned to prevent it from becoming too loose or too tight.
A properly tensioned chain will:
- Cut smoothly and efficiently.
- Reduce wear and tear on the chain and guide bar.
- Minimize the risk of kickback, which can occur when the chain is too loose.
An incorrectly tensioned chain can:
- Cause the chainsaw to bind or stall.
- Increase the risk of chain derailment.
- Put unnecessary strain on the chainsaw’s engine.
Matching the chain length to the guide bar is, therefore, a critical step in ensuring the safe and effective operation of a chainsaw.
To measure the chain length, simply count the number of drive links. Drive links are the links that engage with the sprocket on the chainsaw’s engine. Once you know the number of drive links, you can refer to the manufacturer’s specifications to determine the correct chain length for your chainsaw.
It is important to note that chain length is not the same as chain pitch. Chain pitch refers to the distance between the drive links. The chain pitch must also be matched to the chainsaw’s sprocket. Most chainsaws use a chain pitch of .325 inches or .375 inches. If you are unsure of the chain pitch of your chainsaw, consult the manufacturer’s specifications.
By following these simple steps, you can ensure that your chainsaw chain is the correct length and tension for optimal performance and safety.
2. Tension
Tension plays a critical role in the performance and safety of a chainsaw. A correctly tensioned chain will cut smoothly and efficiently, reducing wear and tear on the chain and guide bar. It will also minimize the risk of kickback, which can occur when the chain is too loose. In contrast, an incorrectly tensioned chain can cause the chainsaw to bind or stall, increase the risk of chain derailment, and put unnecessary strain on the chainsaw’s engine.

Facets of Chain Tension
There are several factors that affect chain tension, including the chain length, the type of chainsaw, and the cutting conditions. The chain length should be matched to the guide bar length to ensure proper tension. If the chain is too short, it will be too tight and can cause the chainsaw to bind or stall. If the chain is too long, it will be too loose and can increase the risk of kickback.
-
Measuring Chain Tension
To measure chain tension, simply pull the chain away from the guide bar at the midpoint. The chain should have about 1/4 inch (6 mm) of play. If the chain is too tight, loosen the tensioner knob or screw. If the chain is too loose, tighten the tensioner knob or screw.

Consequences of Incorrect Tension
Incorrect chain tension can have several negative consequences, including:
- Reduced cutting efficiency
- Increased wear and tear on the chain and guide bar
- Increased risk of kickback
- Damage to the chainsaw’s engine
-
Maintaining Proper Tension
To maintain proper chain tension, it is important to check the tension regularly, especially after prolonged use. It is also important to keep the chain clean and lubricated. A clean and lubricated chain will last longer and cut more efficiently.
By understanding the importance of chain tension and how to measure and maintain it, you can ensure that your chainsaw operates safely and efficiently.
3. Safety
Ensuring the correct chain size on a chainsaw is paramount for safety, optimal performance, and longevity. An incorrectly sized chain can result in a range of issues that compromise the user’s safety and the chainsaw’s effectiveness.
-
Premature Wear
An incorrectly sized chain can cause accelerated wear on the chain and guide bar. When the chain is too long, it will be looser and more prone to slapping against the wood, leading to excessive friction and premature wear. Conversely, a chain that is too short will be tighter and more likely to bind, putting unnecessary strain on the guide bar and increasing the risk of breakage.
-
Reduced Cutting Efficiency
An incorrectly sized chain can significantly reduce the chainsaw’s cutting efficiency. A chain that is too long will be more difficult to control and maneuver, making it harder to make precise cuts. A chain that is too short will not have enough cutting teeth engaged with the wood, resulting in slower and less efficient cutting.
-
Safety Hazards
An incorrectly sized chain can pose several safety hazards. A chain that is too long can increase the risk of kickback, which is a sudden and dangerous upward force that can occur when the tip of the chainsaw makes contact with an object. A chain that is too short can bind and cause the chainsaw to lurch forward, potentially injuring the user.
By understanding the importance of using the correct chain size and following the proper steps to measure the chain, you can ensure the safe and effective operation of your chainsaw.
Frequently Asked Questions about Measuring Chainsaw Chains
Measuring the chain on a chainsaw is a crucial step for ensuring optimal performance and safety. Here are answers to some frequently asked questions about measuring chainsaw chains:
Question 1: Why is it important to measure the chain on a chainsaw?
Answer: Measuring the chain ensures that it is the correct length for the guide bar, which is essential for proper tension. Correct tension prevents the chain from being too loose or too tight, ensuring smooth and efficient cutting while minimizing the risk of kickback and other safety hazards.
Question 2: How do I measure the length of a chainsaw chain?
Answer: To measure the length of a chainsaw chain, count the number of drive links. Drive links are the links that engage with the sprocket on the chainsaw’s engine. Once you know the number of drive links, refer to the manufacturer’s specifications to determine the correct chain length for your chainsaw.
Question 3: What are the consequences of using an incorrectly sized chain?
Answer: Using an incorrectly sized chain can lead to premature wear, reduced cutting efficiency, and safety hazards. A chain that is too long can be loose and prone to slapping, causing excessive friction and wear. A chain that is too short can be tight and more likely to bind, putting strain on the guide bar and increasing the risk of breakage.
Question 4: How often should I check the tension of my chainsaw chain?
Answer: It is important to check the tension of your chainsaw chain regularly, especially after prolonged use. The chain should have about 1/4 inch (6 mm) of play when pulled away from the guide bar at the midpoint. If the chain is too tight or too loose, adjust the tensioner knob or screw according to the manufacturer’s instructions.
Question 5: What is the difference between chain length and chain pitch?
Answer: Chain length refers to the number of drive links in the chain, while chain pitch refers to the distance between the drive links. Both chain length and chain pitch must be matched to the chainsaw’s guide bar and sprocket.
