Proper Storage and Maintenance of Chainsaw Fuel
Understanding how to properly store and maintain chainsaw fuel is crucial for ensuring the longevity and performance of your chainsaw. While gasoline can typically be left in a chainsaw for about 30 days before it starts to degrade, this timeframe can be significantly reduced by the presence of ethanol, a common component in fuel blends. This article will provide you with the essential tips to keep your chainsaw running smoothly and efficiently.
Understanding Ethanol and Its Impact on Fuel
Gasoline with ethanol can start to break down and affect the internal components of your chainsaw even within a week or two. Ethanol is a drying agent that can cause gum and varnish to form in fuel systems, leading to clogs and malfunctions. This is why it's essential to use proper storage techniques and consider the use of fuel stabilizers to minimize the impact of ethanol.
Tips for Proper Chainsaw Fuel Storage
Use Fuel Stabilizer
Adding a fuel stabilizer can extend the life of the gasoline up to 12 months. This is particularly useful for those who don't use their chainsaw frequently. Fuel stabilizers help to prevent the formation of gums, varnishes, and other deposits that can interfere with the performance of the fuel system. Always follow the manufacturer's instructions when using a fuel stabilizer.
Empty the Tank
If you don't plan to use the chainsaw for an extended period, it's best to empty the fuel tank and run the engine until it runs out of gas. This ensures that no fuel is left inside the carburetor, which could be a breeding ground for bacteria and other contaminants. After emptying the tank, run the chain saw for a few minutes to help dry out the system.
Store Properly
Keep your chainsaw in a cool, dry place to minimize fuel degradation. High temperatures and humidity can accelerate the breakdown of gasoline. Avoid storing your chainsaw in direct sunlight or in a damp, humid environment. Regular inspection of the storage area can help you keep track of any signs of moisture or heat damage.
Check Before Use
Always inspect the fuel for any signs of separation or discoloration before using the chainsaw. If you notice any sediment or changes in color, it's a good indication that the fuel is starting to degrade. In such cases, it's best to replace the fuel with fresh gasoline.
Advanced Storage Techniques
For those who plan to store their chainsaws for several months, it's especially important to take additional steps. If you use a fuel stabilizer, you only need to worry about drying the tank out if you store the saw for several months. Follow these steps to extend the life of your fuel:
Empty the Tank and Run the Engine
After pumping enough fuel to run the engine, shut off the chainsaw and let it sit for a few minutes. Then, start the engine again and let it run until it runs out of fuel. This helps to ensure that the fuel tank is as empty as possible.
Dump the Tank and Flog the System
After running the engine, dump the remaining fuel from the tank. Run the carburetor dry and fog the tank and carb with "Fogging Oil." This process helps to coat the internals of the carburetor and fuel lines, preventing moisture and contaminants from entering the system.
Modern Fuel Considerations
With the introduction of 'crappy gas' in recent years, it's even more important to take extra precautions when storing chainsaw fuel. I wouldn't let the fuel sit for more than a month or two, even with the use of additives like Startron. Most saw manufacturers and technicians do not recommend the use of fuel stabilizers, but they can still be useful in certain circumstances.
Personal Policy and Advice
My personal policy and advice is to run your saw dry until it quits and then put the choke on and pull the cord a couple more times. This helps to run the engine for a few extra seconds with the choke on, ensuring that all the fuel is out of the carburetor. However, I don't bother with this if I'm sure to be using the saw within a week or two.
Additionally, get fresh gasoline anytime your old supply is more than three or four months old. This ensures that the fuel you use is in the best condition possible. If you want to always have fresh fuel on hand, you can buy premixed gasoline at most major brand dealers in sealed cans, a liter or so at a time. This keeps well indefinitely and is particularly useful if you need your chainsaw on short notice, such as when a tree falls and is blocking the road or you need firewood quickly.
In conclusion, proper storage and maintenance of chainsaw fuel are crucial for ensuring the longevity and performance of your chainsaw. By following these guidelines and tips, you can help your chainsaw run smoothly whenever you need it.
Conclusion
Properly storing and maintaining chainsaw fuel is not just a matter of convenience; it's a necessity for the longevity and performance of your chainsaw. By understanding the impact of ethanol, utilizing fuel stabilizers, and following storage best practices, you can keep your chainsaw in top condition, ready to take on any task.
