As winter's chill recedes, the thought of storing your snowblower often brings a sigh of relief. However, before tucking it away, a crucial step often overlooked is properly emptying the fuel. Leaving gasoline in the tank and carburetor over the off-season can lead to a host of problems, from gummed-up fuel systems to potential safety hazards. This guide will walk you through the essential process of safely and effectively draining your snowblower's gas, ensuring it's ready to go when the first flakes fall next year.
Understanding why this process is vital is the first step towards a well-maintained snowblower. Stale gasoline can degrade over time, forming varnish and deposits that clog fuel lines and the carburetor, leading to difficult starts and poor performance. Furthermore, storing a snowblower with a full tank of fuel can increase the risk of evaporation and potential fire hazards, especially in warmer storage environments. By following these steps, you'll not only protect your investment but also guarantee a smoother, more reliable experience when you need your snowblower most.
Why Emptying Your Snowblower's Gas is Essential
The primary reason for draining your snowblower's fuel is to prevent the degradation of gasoline over extended periods of non-use. Modern gasoline contains ethanol, a type of alcohol that attracts moisture. When this moisture-laden fuel sits in your snowblower's tank and carburetor for months, it can lead to corrosion and the formation of gummy deposits. These deposits can obstruct fuel flow, making it incredibly difficult to start the engine when winter returns.
Beyond internal engine issues, leaving fuel in the tank can also pose safety risks. Gasoline is highly flammable, and its vapors can accumulate in enclosed storage spaces. While modern snowblowers are designed with safety in mind, reducing the amount of volatile fuel present minimizes potential fire hazards. This is particularly important if your snowblower is stored in a shed, garage, or basement where ventilation might be limited.
Finally, a properly drained fuel system contributes to the overall longevity of your snowblower. By preventing internal corrosion and blockages, you reduce the likelihood of costly repairs and ensure that your machine operates at peak performance for years to come. It’s a simple preventative maintenance step that pays significant dividends in the long run.
Gathering Your Tools and Safety Gear
Before you begin the draining process, it's crucial to gather the necessary tools and safety equipment. You will need a clean, approved gasoline container for collecting the old fuel. This container should be made of metal or a type of plastic specifically designed for gasoline storage and have a tight-fitting lid. A funnel is also essential to prevent spills when transferring the fuel.
Safety is paramount when working with gasoline. Always wear protective eyewear, such as safety glasses or goggles, to shield your eyes from any splashes or fumes. Nitrile gloves are recommended to protect your skin from the fuel and its drying effects. Ensure you are working in a well-ventilated area, preferably outdoors, away from any open flames, sparks, or sources of ignition. Never smoke while handling gasoline.
You may also need a small wrench or screwdriver, depending on your snowblower's fuel cap design, and possibly a siphon pump if your snowblower doesn't have an easily accessible drain plug. Having a rag or paper towels handy will be useful for wiping up any minor drips or spills.
Method 1: Siphoning the Fuel
One of the most common and straightforward methods for emptying your snowblower's gas tank is through siphoning. Begin by ensuring your snowblower is on a level surface and that you have your approved fuel container and funnel ready. Carefully remove the fuel cap from the gas tank. Insert one end of a siphon hose into the fuel tank, ensuring it reaches near the bottom to draw out as much fuel as possible.
With the other end of the siphon hose positioned inside your fuel container, you'll need to initiate the flow of fuel. The simplest way is to use a manual siphon pump, often integrated into the hose. If you don't have a pump, you can carefully suck on the end of the hose until fuel begins to flow, then quickly remove it from your mouth and place it into the container. Be extremely cautious not to ingest any gasoline. Gravity will then do the work, drawing the fuel from the tank into the container.
Continue siphoning until the fuel tank is nearly empty. Once you've removed the bulk of the gasoline, you may want to tilt the snowblower slightly to get the last few drops into your container. Remember to securely cap both the fuel tank and your gasoline container once you are finished.
Method 2: Using the Carburetor Drain Screw
Many snowblowers are equipped with a drain screw on the carburetor, which provides a more direct way to empty the fuel system. Locate the carburetor, typically found at the bottom of the engine where the fuel line connects. You'll see a small screw, often with a hex head, at the lowest point of the carburetor bowl. Place your approved fuel container and funnel directly beneath this screw.
Using an appropriate wrench or screwdriver, carefully loosen and remove the carburetor drain screw. As soon as the screw is removed, fuel will begin to drain from the carburetor bowl into your container. Allow the fuel to drain completely. This method is particularly effective at removing any residual fuel that might be trapped in the carburetor itself, which is a common culprit for starting problems.
Once the fuel has drained, clean the drain screw and the area around the opening with a rag. Reinstall the drain screw and tighten it securely, but do not overtighten, as this could damage the carburetor. This method ensures that the fuel system is thoroughly emptied, leaving no stale gasoline behind.
Post-Draining Procedures and Storage
After you have successfully drained the fuel from both the tank and the carburetor, it's important to perform a few final steps to protect your snowblower during storage. With the fuel system empty, start the engine and let it run until it sputters and dies. This will consume any remaining fuel in the fuel lines and the carburetor, ensuring they are completely dry. This step is crucial for preventing the formation of varnish and gum deposits.
Once the engine has stopped, clean the exterior of your snowblower. Remove any dirt, grass clippings, or debris that may have accumulated. A clean machine is less likely to attract pests and is easier to inspect when you take it out of storage. Consider applying a light coat of oil to any exposed metal parts to prevent rust, especially if your snowblower will be stored in a humid environment.
Finally, store your snowblower in a clean, dry, and secure location. A garage, shed, or basement is ideal. If possible, cover the machine with a breathable snowblower cover to protect it from dust and moisture. Avoid storing it near any sources of ignition or in areas where temperatures fluctuate drastically.
