How To Tighten A Husqvarna Chainsaw Chain - 9 Easy Tips

Know how to tighten a husqvarna chainsaw chain is an important maintenance task that can help ensure safe and efficient operation. To tighten a Husqvarna chainsaw chain, follow these steps. Remember to regularly check and adjust your chainsaw chain’s tension, as proper tension is crucial for optimal performance and safety during operation.

  1. Turn off the chainsaw and unplug the spark plug to ensure safety.
    2. Locate the chain tensioning screw on the side of the chainsaw bar.
    3. Use a flathead screwdriver or the tool provided with your chainsaw to turn the tensioning screw clockwise.
    4. Continue turning until you feel resistance and see that the chain is snug against the bar but still able to move freely.
    5. Check the tension by pulling up on the chain at its midpoint. It should lift about 1/8 to 1/4 inch from the bar.
    6. Once you have achieved the proper tension, tighten the lock nut on the tensioning screw to secure it in place.
    7. Finally, give the chain a few test cuts to ensure it operates smoothly and safely.

Below we provide tips in detail.

1.Check The Chain Tension

Check The Chain Tension

There are several ways to check the chain tension on a Husqvarna chainsaw. One method is to use a chain tension gauge, which allows you to easily see the amount of tension in the chain. Other methods include using the quick-release lever, regularly checking the chain tension, and adjusting it to maintain optimal performance.

Regularly checking the chain tension and adjusting it properly will help ensure that your chainsaw remains in good working condition and performs at its best. Storing your chainsaw upright to stay clean and dry is also a good idea. This will help prevent rust and other damage over time.

2.Tensioning Bolts And Links

You must use tensioning bolts and links to tighten a Husqvarna chainsaw chain quickly and easily. Tensioning bolts are inserted through the chain and into the saw frame, while links are connected to the tensioning bolts and provide the necessary tension.

To tighten a Husqvarna chainsaw chain, loosen all the tensioning bolts and links. Next, adjust the tensioning bolts until the chain is tight but not too tight. Finish tightening the chain by connecting the links and tightening the tensioning bolts. You should repeat this process until the tensioning bolts are connected and tightened.

3.Tighten The Chain

Tighten The Chain

There are several ways to tighten a Husqvarna chainsaw chain quickly and easily. Some of the most common methods include using a spanner or wrench, using the bar oiler, or tightening the chain with a crank tool. Each method has its advantages and disadvantages.

Choosing the right method for the specific chainsaw chain and application is important. If you want a quick and easy way to tighten your chain, consider using one of these methods. However, if you have the time, consider taking it slow and tightening each link individually to ensure long-term chain life.

4.Tighten The Sprocket Nut

To quickly and easily tighten a Husqvarna chainsaw chain, follow these steps: loosen the sprocket nut by turning it anticlockwise. Then tighten the sprocket nut by turning it clockwise. Finally, check chain tension by pulling the chain towards you. The chain should have no slack and be firm against the sprocket.

Repeat the tightening process if there is any slack in the chain until properly tensioned. By following these steps, you can ensure your chain remains tight and functions properly over time.

5.Tighten The Drive Belt

Maintaining proper tension on the chain is important to ensure it stays tight and safe. One method of doing this is by hand-tightening the chain. Another efficient way to tighten the chain is using a chain tensioner.

These devices help reduce the pressure required when tightening or loosening chains. You can also use a chainsaw sharpener to quickly and easily sharpen your chainsaw chain. Other methods for ensuring your chain stays in good shape include:

  • Regularly lubricating it with a Husqvarna chain lubricant
  • Checking the chain for wear
  • Replacing it if necessary

This will ensure your chain is safe and efficient over time.

6.Check For Binding

Check For Binding

Remove any excess slack from the chain when checking for binding by cranking the chain tensioner handle. Next, use the chain tool to tighten the chain. Finally, check the alignment of the chain by rotating the tool around the bar sprocket. This process ensures that the chain is tight and free-running in every direction.

To ensure long life from your chainsaw, it is important to frequently check for and address potential issues with chain tensioning and alignment.

7.Use A Wrench

The quickest and easiest way to tighten a Husqvarna chainsaw chain is to use a wrench. Wrenches are available in different sizes and shapes and are designed to fit different chainsaws. If you own more than one chain or saw, have multiple wrenches to avoid over-tightening the chain.

When using a wrench, ensure the handle is securely attached to the chain saw’s tensioning screw or bolt. Over-tightening the chain can greatly damage and increase the risk of breaking it. Additionally, you can use a file to clean the chain and remove any obstructions. By tightening your chain and lubricating it properly, you can help ensure it operates efficiently and lasts for years without maintenance.

8.Use Wd40 To Loosen The Chainsaw Chain

Use WD40 To Loosen The Chainsaw Chain

You can use WD-40 to loosen chainsaw chains quickly and easily. Regularly tightening the Chainsaw chain would be best to ensure proper cutting performance. The chain must be tensioned properly to prevent the teeth from binding or skipping over the cut material.

When the chain is properly tensioned, it reduces the risk of burning the wood or damaging the saw’s motor. Additionally, regular chain adjustment keeps the teeth aligned for consistent cutting. After use, you can use WD-40 to clean the chainsaw blade and prevent the build-up of residue and debris on the teeth. This makes for a cleaner and more efficient cutting process next time you use it.

9.Use A Husqvarna Chainsaw Chain Tensioner

Use A Husqvarna Chainsaw Chain Tensioner

You can use Husqvarna chain tensioners to quickly and easily tighten a chainsaw chain. Specially made from durable materials and are easy to use. Most chain tensioners feature an adjustment screw to customize the tightness.

If your Husqvarna chainsaw doesn’t have a chain tensioner, you can use a wrench to tighten the chain. Always wear safety gear, such as gloves and eye protection, when adjusting a chain, regardless of your chosen method. Ensuring the right tension is important so the chain stays in good working order.

Tips For Keeping Your Chainsaw Chain Sharp

You can follow a few tips when keeping a chainsaw chain sharp. Firstly, keep the saw’s chain properly lubricated to ensure it runs smoothly without much tension. This will prevent the chain from potential damage or rust, essential for its lifespan.

Chainsaw chain sharpening is one of the most important maintenance tasks you can perform on your saw. A dull chainsaw chain will be difficult to operate and cause serious injury if you encounter a tree or other object while operating your saw. Here are some tips for keeping your chainsaw chain sharp:

  • Sharpen the chain every few hours or as needed. If it’s feeling tight and chatty when you try to start the engine, it needs sharpening.
  • Use a quality blade grit stone that matches your chainsaw’s teeth profile and operator style (standard vDuramaxAX). The type of stone and how often you sharpen it depends on how frequently the chain becomes dull. Use standard stones with medium grits once per month; for Duramax stones with higher grits, use them twice monthly or more often, depending on weariness/use conditions.
  • Keep an eye out for signs if your stone is becoming too dull – this will indicate that you need to re-grit it sooner rather than later.


Chainsaw chain tensioning is essential to maintaining your chainsaw’s chain life and improving cutting performance. Using the above tips for tightening the chainsaw chain will help you ensure that your chain remains intact and cuts efficiently, helping you to cut more trees with fewer chains.

Tightening the chain on your Husqvarna chainsaw is a simple yet essential maintenance task that ensures optimal performance and safety. By following the steps on how to tighten a Husqvarna chainsaw chain, you can easily tighten your chainsaw chain and keep it in proper working condition.

Always wear protective gear and take necessary precautions when working with power tools. With a well-tightened chain, you can confidently tackle any cutting job with your Husqvarna chainsaw. Keep your chainsaw running smoothly and efficiently by regularly checking and tightening the chain as needed.
