Step 1: Inspect Your Chainsaw Chain Regularly

The first step in knowing when to replace chainsaw chain is to inspect it regularly. You should check the chain for signs of wear and damage every time you use your chainsaw. Look for things like:

  • Dull or chipped cutting teeth
  • Uneven wear on the cutting teeth
  • Loose or missing rivets
  • Damaged or worn-out drive links
  • Cracks or other signs of damage to the chain links
  • Stretched or elongated chain

If you notice any of these signs, it’s time to replace your chainsaw chain. Ignoring these signs can lead to reduced cutting performance, overheating of the chainsaw, and even safety risks.

Step 2: Determine the Correct Replacement Chain

Once you’ve determined that it’s time to replace your chainsaw chain, you need to find the right replacement chain for your chainsaw. The easiest way to do this is to consult your chainsaw’s manual, which should have information on the correct chain size and type for your chainsaw. If you don’t have a manual, you can often find this information on the chainsaw manufacturer’s website.

It’s important to choose the right replacement chain, as using the wrong chain can cause serious safety risks. The chain must fit the bar properly and have the correct number of drive links for your chainsaw.

Step 3: Remove the Old Chain

Before you can install the new chain, you need to remove the old chain from your chainsaw. To do this, you’ll need to:

  1. Release the brake on your chainsaw
  2. Remove the bar cover and loosen the tensioning screw
  3. Remove the old chain from the bar and sprocket

Step 4: Install the New Chain

With the old chain removed, it’s time to install the new chain. Follow these steps to install the new chain correctly:

  1. Place the new chain over the bar, ensuring that the cutting teeth are facing in the right direction
  2. Loop the chain over the sprocket and align the drive links with the bar groove
  3. Reattach the bar cover and tighten the tensioning screw until the chain is snug but not too tight
  4. Check the tension of the chain by pulling it away from the bar – there should be just enough slack for you to slip a coin between the chain and the bar
  5. Finally, tighten the tensioning screw again and make sure the chain moves freely around the bar

Step 5: Test Your Chainsaw

Once you’ve installed the new chain, it’s important to test your chainsaw to make sure it’s working properly. Start by checking the chain tension again and adjusting it if necessary. Then, test your chainsaw by making a few test cuts on a piece of wood. If the chainsaw cuts smoothly and quickly, you’ve done a good job. If not, you may need to adjust the chain tension or consider other maintenance tasks.

Conclusion

Knowing when to replace chainsaw chain is an important part of chainsaw maintenance. By inspecting your chainsaw chain regularly and following the steps outlined above, you can ensure that your chainsaw is safe, reliable, and performing at its best. Remember to always choose the correct replacement chain for your chainsaw, and never use a chain.
