If you’re in the construction industry, you know how important it is to have reliable equipment. Stihl is a brand that is trusted by professionals all around the world, and their concrete saws are no exception. However, even the best equipment can sometimes experience issues, such as flooding.
When a Stihl concrete saw becomes flooded, it means that there is an excessive amount of fuel in the engine. This can happen if the saw is left unused for a long period of time or if it is not properly maintained. Starting a flooded saw can be a frustrating task, but with the right steps, you can get your saw up and running again in no time.
Step 1: Before attempting to start a flooded Stihl concrete saw, it is important to take some safety precautions. Make sure you are in a well-ventilated area and away from any sources of ignition. Ensure that the saw is turned off and the spark plug is disconnected. This will prevent any accidental starts and reduce the risk of injury.
Step 2: Once you have taken the necessary safety precautions, it’s time to start the process of starting the flooded saw. Begin by setting the choke control to the closed position. This will help to limit the amount of air entering the carburetor, making it easier to start the engine.
Step 3: With the choke in the closed position, pull the starter rope a few times. This will help to clear out any excess fuel from the engine. Be careful not to pull too forcefully, as this can damage the starter mechanism. Aim for a smooth and controlled motion.
Step 4: After pulling the starter rope a few times, move the choke control to the open position. This will allow more air to enter the carburetor, creating a leaner fuel mixture. Once the choke is in the open position, pull the starter rope again, but this time with a little more force. You should start to hear the engine sputter and eventually start.
Step 5: Once the engine starts, let it run for a few minutes to ensure that the excess fuel is burned off and the engine is running smoothly. If the engine continues to run rough or sputter, you may need to repeat the steps above or seek professional assistance.
Starting a flooded Stihl concrete saw can be a challenging task, but by following these steps, you can get your saw back in working order. Remember to always prioritize safety and take the necessary precautions. With proper maintenance and care, your Stihl concrete saw will continue to perform at its best.

To clear the air filter, follow these steps:
- Start by locating the air filter cover on the side of the saw’s engine.
- Using a screwdriver, remove the screws that secure the air filter cover in place.
- Carefully lift off the air filter cover to reveal the air filter element.
- Inspect the air filter for dirt, debris, and oil buildup. If it is dirty, it will need to be cleaned or replaced.
- If the air filter is dirty but still functional, gently tap it against a hard surface to remove loose debris.
- If the air filter is heavily soiled or damaged, replace it with a new one. Stihl recommends using genuine Stihl air filters for optimal performance.
- Once the air filter is clean or replaced, reattach the air filter cover and secure it with the screws.
Tips:
- It is a good practice to clean or replace the air filter regularly, even if the saw is not flooded. This helps to maintain proper airflow and prevent potential engine problems.
- Inspect the air filter for any signs of damage, such as tears or holes. If the air filter is damaged, it should be replaced immediately.
- Consider using a Stihl air filter pre-cleaner in dusty or dirty working conditions. This additional layer of filtration can help extend the life of the air filter.
Drain the Fuel
Starting a flooded Stihl concrete saw can be a daunting task, but one of the first steps you can take is to drain the fuel from the machine. This is an essential step to prevent further damage and to allow for a clean start.
Here are the steps to drain the fuel from your flooded Stihl concrete saw:
- Locate the fuel tank on your concrete saw. It is typically located near the rear handle or on the side of the machine.
- If the saw has been running recently, let it cool down completely before proceeding.
- Unscrew the fuel tank cap and carefully pour the fuel into an approved container. Be sure to avoid any sparks or open flames while handling fuel.
- Once the fuel has been drained, inspect the fuel tank for any debris or water. Clean the tank if necessary.
- Replace the fuel tank cap tightly to prevent any fuel leakage.
By draining the fuel from your flooded Stihl concrete saw, you are taking the necessary step to remove excess fuel and allowing for a fresh start. This will make it easier to start the saw and help prevent further flooding issues in the future.
Remove the Spark Plug
To start a flooded Stihl concrete saw, it’s essential to remove the spark plug. This step is crucial as it allows for the excess fuel to be burned off and prevents further flooding. Follow the steps below to remove the spark plug:
