Step 2: Check the Oil and Fuel Levels

Before starting the engine, it’s essential to check the oil and fuel levels. To check the oil level, remove the oil filler cap and wipe the dipstick clean. Insert the dipstick back into the filler hole and remove it again to check the oil level. The oil level should be between the "L" and "H" marks on the dipstick.

To check the fuel level, locate the fuel tank and check that there is enough fuel to run the engine. If the fuel level is low, fill up the tank with fresh gasoline. It’s important to use gasoline with an octane rating of at least 87.

Step 3: Attach the Hose and Nozzle

Before starting the engine, attach the high-pressure hose to the pressure washer’s water outlet. Screw the other end of the hose onto the water supply. Next, attach the spray gun to the high-pressure hose and attach the desired nozzle to the spray gun. There are different types of nozzles available, including a 0-degree nozzle, 15-degree nozzle, 25-degree nozzle, and 40-degree nozzle.

Step 4: Turn On the Water Supply

Before starting the engine, turn on the water supply to the pressure washer. Make sure that there is enough water flowing to the pressure washer to prevent damage to the pump.

Step 5: Turn On the Engine

Once you’ve completed the previous steps, turn on the engine by pulling the starter cord. It may take a few pulls to get the engine started, especially if it’s the first time you’re using the pressure washer. Once the engine is running, let it warm up for a few minutes before using it.

Step 6: Adjust the Pressure

Once the engine is warm, adjust the pressure using the pressure regulator. The pressure regulator controls the pressure of the spray, and you can adjust it to suit your needs. It’s important to note that higher pressure doesn’t always mean better cleaning results. Sometimes, lower pressure is more effective, depending on the type of surface you’re cleaning.

Step 7: Start Cleaning

Now that the pressure washer is up and running, you can start cleaning. Move the spray gun back and forth over the surface you want to clean, making sure to maintain a consistent distance from the surface. Always wear protective gear, including safety glasses and gloves, when using the pressure washer.

Q2: Can I use any type of gasoline in my Subaru EA190V pressure washer?

A: No, it’s important to use gasoline with an octane rating of at least 87 to ensure optimal performance.

Q3: What type of nozzle should I use for cleaning my deck?

A: It’s recommended to use a 25-degree nozzle for cleaning decks as it provides enough pressure to remove dirt and grime without damaging the wood.


Starting a Subaru EA190V pressure washer is easy, but it’s essential to follow the steps correctly to ensure optimal performance and safety. Remember to always read the owner’s manual, check the oil and fuel levels, attach the hose and nozzle correctly, turn on the water supply, and adjust the pressure before starting to clean.
