How To Fix A Stihl Concrete Saw
If you are a professional construction worker or a DIY enthusiast, you understand the importance of having a reliable concrete saw. However, like any other power tool, even the best Stihl concrete saws can experience issues over time. Fortunately, many common problems can be easily fixed without the need for a professional repair. With a little knowledge and some basic tools, you can get your Stihl concrete saw up and running again in no time.
One of the most common issues with a Stihl concrete saw is a dull or damaged blade. This can lead to poor cutting performance and can even be dangerous. To fix this issue, start by removing the blade from the saw and inspecting it for any signs of damage or dullness. If you notice any chips or nicks, you can try to sharpen the blade using a file or replace it with a new one. Remember to always wear proper safety gear, such as gloves and protective eyewear, when working with blades.
Another common problem with a Stihl concrete saw is difficulty starting the engine. This can be caused by a variety of factors, such as a dirty air filter or a clogged fuel line. To fix this issue, first, check the air filter and clean or replace it if necessary. Next, inspect the fuel line for any blockages and clear them if found. You should also check the spark plug and make sure it is clean and properly gapped. If these steps don’t solve the problem, you may need to take the saw to a professional for further diagnosis.
Lastly, if you notice that your Stihl concrete saw is not cutting straight or is cutting at an angle, the issue may lie with the guide bar or the chain tension. Start by checking the guide bar for any damage or warping and replace it if needed. Then, adjust the chain tension by loosening the nuts on the guide bar and moving it until there is about a quarter-inch gap between the bottom of the guide bar and the chain. Finally, tighten the nuts and test the saw’s cutting performance.
In conclusion, a Stihl concrete saw can be a reliable and powerful tool for any construction project. However, like any other tool, it can experience issues. By following the steps outlined in this article, you can easily fix common problems with your Stihl concrete saw and ensure it continues to perform at its best.

Common Problems with Stihl Concrete Saws
Stihl concrete saws are reliable and powerful tools, but like any machine, they can experience problems from time to time. Here are some common problems you may encounter with a Stihl concrete saw and how to fix them.
Lack of Power or Cutting Performance
If your Stihl concrete saw is lacking power or not cutting as efficiently as it should, there are a few things you can check. First, inspect the air filter and clean or replace it if it is dirty or clogged. A dirty air filter can restrict airflow and hinder performance. Additionally, check the spark plug for any signs of wear or fouling and replace it if needed. Another potential cause of low power or cutting performance could be a clogged or dirty fuel filter. Check the fuel filter and clean or replace it if necessary. Lastly, ensure that the saw’s blade is not worn or damaged, as this can also affect cutting performance.
Starting Problems
If you are having trouble starting your Stihl concrete saw, the first thing to check is the fuel mixture. Make sure you are using the correct fuel-to-oil ratio and that the fuel is fresh. Stale fuel can make starting the saw more difficult. Additionally, check the spark plug for proper connection and clean or replace it if needed. If the saw still does not start, the carburetor may need to be cleaned or adjusted. Refer to the manufacturer’s instructions for proper carburetor maintenance.
Oil Leaks
If you notice oil leaking from your Stihl concrete saw, it is important to address this issue as soon as possible to prevent any damage. Check the oil cap and make sure it is securely tightened. If the oil cap is loose, tighten it until snug. If the oil leak persists, inspect the oil tank and oil lines for any cracks or damage. Replace any damaged parts as needed. Additionally, ensure that you are using the correct type of oil for your saw and that it is not overfilled.
Vibrations
If your Stihl concrete saw is vibrating excessively, it can be uncomfortable to use and may indicate a problem. Check the blade for any cracks or damage and replace it if necessary. Ensure that the blade is properly tightened and balanced. Excessive vibrations can also be caused by a damaged or worn-out drive belt. Inspect the drive belt and replace it if needed. If the vibrations persist, it is recommended to have the saw inspected by a professional.
Problem | Possible Cause | Solution |
---|---|---|
Lack of Power or Cutting Performance | Dirty air filter, worn spark plug, clogged fuel filter, or damaged blade. | Clean or replace air filter, replace spark plug, clean or replace fuel filter, or replace blade. |
Starting Problems | Incorrect fuel mixture, stale fuel, faulty spark plug, or dirty carburetor. | Use correct fuel mixture, use fresh fuel, replace spark plug, or clean carburetor. |
Oil Leaks | Loose oil cap, damaged oil tank or lines, incorrect oil type, or overfilled oil. | Tighten oil cap, replace damaged parts, use correct oil type, or ensure proper oil level. |
Vibrations | Cracked or damaged blade, loose or unbalanced blade, or damaged drive belt. | Replace blade, tighten and balance blade, or replace drive belt. |
How to Diagnose and Troubleshoot Issues
In order to fix a Stihl concrete saw, it is crucial to diagnose and troubleshoot the issues correctly. Here are some steps to help you with this process:
1. Identify the Problem: Start by identifying the specific issue with your Stihl concrete saw. Is it not starting? Is it running rough or losing power? Does it have a fuel or oil leak? Understanding the problem will help you determine the appropriate solution.
2. Check the Fuel: One common issue with concrete saws is fuel-related problems. Make sure you have fresh fuel in the machine and that the fuel lines are clean and not clogged. Check the fuel filter and replace it if necessary. Ensure that the fuel tank vent is not obstructed.
3. Inspect the Air Filter: A dirty or clogged air filter can cause issues with the saw. Remove the air filter and clean or replace it as required. A clean air filter allows for proper air intake and prevents engine problems.
4. Examine the Spark Plug: A faulty spark plug can lead to starting issues or poor performance. Remove the spark plug and inspect it for damage or fouling. Clean or replace the spark plug if needed, ensuring it is correctly gapped.
5. Check the Carburetor: The carburetor controls the fuel and air mixture in the engine. If the saw is running lean or rich, it may be due to a carburetor problem. Clean the carburetor and ensure the jets and passages are clear. Adjust the carburetor settings if necessary.
6. Inspect the Ignition System: The ignition system includes components such as the ignition coil and spark arrestor. Check these parts for damage or wear. Test the ignition coil for proper functioning using a multimeter. Clean or replace the spark arrestor if it is clogged or damaged.
7. Review the Compression: Low compression can result in starting issues or lack of power. Perform a compression test using a compression gauge to measure the engine’s compression. If the compression is low, it may indicate a problem with the piston rings or cylinder, requiring further inspection and repair.
8. Seek Professional Help: If you have exhausted all troubleshooting options or are unsure about performing repairs yourself, it is advisable to seek help from a qualified Stihl service technician. They have the expertise and equipment to diagnose and fix complex issues with your concrete saw.
By following these steps, you can diagnose and troubleshoot issues with your Stihl concrete saw and take the necessary steps to fix it, ensuring optimal performance and longevity.
