A chainsaw is an essential tool for various tasks, including tree felling, pruning, and cutting firewood. However, if the chainsaw chain becomes tangled, it can hinder the tool’s effectiveness and pose potential safety hazards. This detailed guide will walk you through the process of safely and effectively untangling a chainsaw chain, so you can get back to work with minimal downtime.

Step 1: Ensure Safety Precautions

1.1 Disconnect Power Source: Before working on the chainsaw, disconnect the power source to avoid accidental startup. If it’s an electric chainsaw, unplug it from the outlet, and if it’s a gas-powered chainsaw, turn off the engine and remove the spark plug wire.

1.2 Wear Protective Gear: Put on appropriate safety gear, including gloves and safety glasses, to protect yourself from potential injuries during the untangling process.

1.3 Secure the Chainsaw: Place the chainsaw on a stable, flat surface, such as a workbench or table, with the chain and bar easily accessible.

Step 2: Inspect and Loosen the Chain

2.1 Inspect the Chain: Examine the tangled chain to identify the areas where it’s twisted or looped. Gaining an understanding of the tangle will help you untangle the chain more effectively.

2.2 Loosen the Chain: To make the untangling process easier, loosen the chain tension by releasing the chain tensioner. Consult your chainsaw’s user manual for specific instructions on how to do this, as it may vary depending on the chainsaw model.

Step 3: Untangle the Chainsaw Chain

3.1 Identify the Loop: Locate the largest loop in the tangled chain. The largest loop is typically the best starting point for untangling, as it’s often the primary cause of the tangle.

3.2 Work from the Outside: Working from the outside of the loop, use your fingers or needle-nose pliers to gently separate the chain links. Be patient and avoid using excessive force, as this can cause further tangling or damage the chain.

3.3 Straighten Smaller Loops: As you work your way through the tangle, you may encounter smaller loops or twists. Untangle these smaller loops by gently working the chain links apart with your fingers or needle-nose pliers.

3.4 Check for Damage: Once the chain is untangled, inspect it for any signs of damage, such as bent, twisted, or broken links. If you find any damaged links, replace the chain or consult a professional for repair.

Step 4: Reassemble and Tension the Chain

4.1 Reattach the Chain: With the chain untangled, reattach it to the chainsaw bar, making sure it’s properly seated in the bar groove.

4.2 Adjust the Chain Tension: Tighten the chain tensioner to achieve the proper tension. The chain should be snug against the bar but still able to move freely when pulled by hand. Refer to your chainsaw’s user manual for specific instructions on how to adjust the chain tension.

4.3 Test the Chainsaw: Reconnect the power source and start the chainsaw. Carefully test the chain’s movement to ensure it’s running smoothly and without any issues.


Untangling a chainsaw chain may seem daunting, but with patience and the right approach, it’s a task that can be accomplished safely and effectively. By following the steps outlined in this guide, you can ensure that your chainsaw chain is untangled and ready for use, allowing you to get back to work with minimal downtime. Always remember to prioritize safety and inspect your chainsaw
