How to Repair Your Chainsaw: A Comprehensive Guide (Local Tips & Reviews)

Chainsaws are an essential tool for any homeowner or tree-care professional. They make tough tasks like cutting down trees, trimming branches, and shaping hedges much more manageable. But when your chainsaw stops working or fails to perform, it can be frustrating, time-consuming, and dangerous. That’s why it’s important to keep your chainsaw maintained and know how to repair it when something goes wrong. In this comprehensive guide, we’ll walk you through how to repair your chainsaw and get it back up and running in no time.

Step 1: Identify the problem

Before you can begin repairing your chainsaw, you need to know what’s wrong with it. There are many different issues that can cause a chainsaw to stop working correctly. Some common problems include:

– A dull or damaged chain
– A dirty or clogged air filter
– A worn or damaged spark plug
– A loose or damaged chain brake
– A damaged or worn fuel line

To identify the problem with your chainsaw, do a visual inspection of the machine, and listen for any unusual noises or sounds when you start the chainsaw. Once you’ve identified the issue, you can move on to the next step.

Step 2: Gather your tools

Once you know what’s wrong with your chainsaw, you’ll need to gather the tools you’ll need to make the repair. Some common tools you may need include:

– Wrenches or pliers
– Screwdrivers
– Spark plug wrench
– Chain saw file
– Chain saw guide
– Chain saw oil

Step 3: Disassemble the Chainsaw

To repair your chainsaw, you may need to disassemble it to access the parts that need to be repaired or replaced. Refer to the owner’s manual for instructions on how to remove the chainsaw parts safely. It’s essential to follow the instructions carefully to avoid damaging your chainsaw or injuring yourself.

Step 4: Repair or Replace Parts

After disassembling your chainsaw, you can inspect the parts and repair or replace any damaged parts. Some common repairs include:

– Sharpening the chain
– Cleaning or replacing the air filter
– Replacing the spark plug
– Tightening the chain brake
– Replacing the fuel line

For some repairs, like sharpening the chain, you can do it yourself with the right tools. However, for repairs like replacing the spark plug, it’s best to seek help from a professional if you’re not sure how to do it.

Step 5: Reassemble the Chainsaw

Once the necessary repairs have been made, it’s time to reassemble your chainsaw. Follow the instructions in your owner’s manual to ensure that you reassemble the chainsaw correctly. Take time to check that all the parts are correctly in place and that all the bolts and screws are tightened. Lubricate the chainsaw with oil to ensure that the parts are well-oiled and moving freely.

Step 6: Test the Chainsaw

Finally, it’s time to test your chainsaw. Try starting it up a few times to ensure that it starts correctly without any unusual noises. After that, test the saw by cutting some branches or logs to ensure that everything is working correctly. If your repaired chainsaw still doesn’t work correctly, it’s best to seek help from a professional to avoid injuring yourself.


Repairing a chainsaw is a do-it-yourself job that requires some knowledge and tools. However, with this comprehensive guide, you can fix your chainsaw when it is not functioning correctly. Remember always to wear safety gear when working on chainsaws and seek help from a professional if you’re not sure how to make a repair. Keep your chainsaw maintained, and it will serve you for years to come.
