How Much Chain Tension on an Electric Chainsaw?55

Maintaining proper chain tension is crucial for the safe and efficient operation of an electric chainsaw. An overly loose chain can derail or snap, while an excessively tight chain puts unnecessary strain on the motor and guide bar. Here's a comprehensive guide to understanding the ideal chain tension for electric chainsaws:

Determining the Correct Tension

The proper chain tension varies depending on the model and make of the electric chainsaw. However, a general rule of thumb is to aim for a tension where the chain deflects approximately 1.3-1.9 centimeters (0.5-0.75 inches) when pulled midway between the guide bar tip and the chain tensioner.

To check the tension, grasp the chain with both hands and pull it away from the guide bar. If the chain moves freely, it is too loose. Conversely, if it resists pulling or binds, it is too tight.

Adjusting Chain Tension

Most electric chainsaws feature a chain tensioner that allows for easy adjustment. Typically, there are two types of tensioners:
Side-Access Tensioner: Located on the side of the chainsaw, this type of tensioner is typically adjusted using a flathead screwdriver or a dedicated tool.
Bottom-Access Tensioner: Positioned at the bottom of the chainsaw, this tensioner is often adjusted using a hex key or a wrench.

To adjust the chain tension:
Loosen the tensioner lock nut.
Turn the tensioner adjustment screw to increase or decrease tension.
Tighten the tensioner lock nut.
Recheck the chain tension by pulling it.
Repeat steps 2-4 until the desired tension is achieved.

Consequences of Improper Chain Tension

Improper chain tension can lead to a range of issues, including:
Loose Chain: Can derail, snap, or catch on obstacles.
Tight Chain: Puts excessive strain on the motor and guide bar, leading to premature wear and overheating.
Reduced Cutting Efficiency: An overly loose chain will not cut effectively, while an excessively tight chain will bind and stall the motor.
Increased Risk of Kickback: A loose chain can cause kickback, which is the sudden and dangerous upward thrust of the chainsaw.

Tips for Maintaining Proper Chain Tension

To ensure optimal performance and safety, follow these tips:
Check the chain tension regularly, especially before each use.
Re-tension the chain as it stretches during operation.
If the chain tension requires frequent adjustment, consult a professional for potential underlying issues.
Use only high-quality chain oil to lubricate and extend the life of the chain.

Conclusion

Proper chain tension is essential for the safe and effective operation of an electric chainsaw. By maintaining the correct tension, you can prevent accidents, extend the life of your chainsaw, and ensure optimal cutting performance. Regularly checking and adjusting the chain tension is a simple yet crucial maintenance task that can significantly impact the overall safety and efficiency of your chainsaw.
