Step 4: Dispose of the Old Fuel Properly

Once you have siphoned out the old fuel, make sure to dispose of it properly. Old fuel can be hazardous, so it's important to take it to a designated disposal site or recycling centre. Do not pour it down the drain or into the environment.

Step 5: Refill with Fresh Fuel

After disposing of the old fuel, you can now refill the tank with fresh fuel. Use the appropriate type of fuel recommended by the manufacturer. Fill the tank to the recommended level, being careful not to overfill it.

Step 6: Start the Pressure Washer

Now that you have fresh fuel in the tank, you can attempt to start the pressure washer. Follow the manufacturer's instructions for starting the machine. You may need to prime the engine by squeezing the primer bulb a few times to get the fresh fuel into the engine.

It is important to note that you should always refer to your pressure washer's user manual for specific instructions and safety precautions. Each model may have unique requirements for fuel type, disposal, and engine maintenance. Additionally, regular maintenance and proper storage of your pressure washer can help prevent fuel-related issues in the future.

Using a fuel stabiliser

• Fuel stabiliser is necessary unless you plan on using the washer a few times every month.
• It is simple to add fuel stabiliser; just pour it into the tank before topping off with fresh gasoline.
• Always follow the instructions on the stabiliser label for the correct ratio of stabiliser to gasoline. Typically, it will be a ratio like 1:1 (1 ounce of stabiliser to 1 gallon of gas) or 1:2.5.
• You can add the required amount of stabiliser to a fuel can, mix it, and then add it to your engine.
• After filling up, let the engine run for a few minutes to circulate the stabiliser.
• Remember, stabiliser only works with fresh gasoline. If you have stale gas in your tank, drain it before adding stabiliser.
• You can purchase fuel stabiliser online, at auto parts stores, or even your local gas station.
• If you need to store your pressure washer for longer than 24 months, drain the fuel tank and refill it when needed.

By using a fuel stabiliser, you can keep your pressure washer's engine running smoothly and efficiently, saving you time and money on repairs and maintenance.

Draining the fuel tank

Locate the Fuel Tank: Find the fuel tank on your pressure washer. It is usually located near the engine or the base of the machine.

Prepare a Container: Place a suitable container next to the pressure washer to catch the drained fuel. Make sure the container is large enough to hold the amount of fuel in the tank and is made of a material that is safe for storing fuel, such as a fuel-safe plastic or metal container.

Turn Off the Pressure Washer: Before draining the fuel, make sure the pressure washer is turned off and the engine is cool. This is an important safety precaution to avoid any accidental spills or injuries.

Drain the Fuel: There are a few ways to drain the fuel from the tank:

• Siphoning: Use a siphon pump or a manual siphoning method to remove the fuel from the tank. Place the siphon tube into the fuel tank and pump it to draw out the fuel. Collect the fuel in your container.
• Tipping the Machine: If your pressure washer doesn't have a removable fuel tank or a drain plug, you may need to carefully tip the machine on its side to drain the fuel. Place your container underneath the fuel tank and slowly tilt the machine to let the fuel flow out. Be cautious to avoid spilling fuel and always keep flammable liquids away from open flames or sparks.
• Removing the Fuel Tank: If your pressure washer allows for easy access and removal of the fuel tank, you can detach it and pour the fuel into your container.

Dispose of the Fuel Properly: Once you have drained the fuel, make sure to dispose of it properly. Do not pour it down the drain or into the environment. Take the container with the drained fuel to a designated fuel disposal location or recycling centre.

By following these steps, you will be able to effectively drain the fuel tank of your pressure washer, ensuring that it is ready for storage or maintenance. Remember to always put your safety first when handling flammable liquids and to refer to your pressure washer's user manual for any model-specific instructions.

Cleaning the carburettor

To clean the carburettor of your pressure washer, you will need to first drain the gas tank. Old gas can cause problems with the engine, so it is important to drain and replace it if your pressure washer has been sitting unused for a long period of time.

To drain the gas tank, simply remove the line at the carburettor and let the fuel drain into a container. Next, remove the float bowl on the carburettor and clean it. The float bowl is part of the carburettor and can be cleaned with carburettor and choke cleaner.

Once the float bowl is clean, replace the spark plug, and with the spark plug out, put a teaspoon of fuel into the spark plug hole, then reinstall the spark plug and try to start the engine.

If your pressure washer still won't start, you may need to take further steps to clean the carburettor. One way to do this is by using a carburettor cleaning kit, which can be purchased at most hardware stores. The kit will include a can of carburettor cleaner and a hose with a nozzle that attaches to the carburettor. Follow the instructions that come with the kit to clean the carburettor.

Another way to clean the carburettor is to remove it from the engine and disassemble it. This can be a more complicated process, but it will allow you to clean all of the individual parts of the carburettor thoroughly. Once the carburettor is removed, use a carburettor cleaner to spray all of the parts, then use a small brush to scrub away any built-up dirt or debris. Reassemble the carburettor and reinstall it on the engine, then try starting the pressure washer again.
