How to Start a Generac Pressure Washer
Do you have a Generac pressure washer that you need to start? Are you unsure of how to do it? Don’t worry, we’re here to help. In this guide, we will walk you through the process of starting your Generac pressure washer. It is very simple and only takes a few minutes. We will also provide some tips on how to get the most out of your pressure washer. So, let’s get started!

Process Of Starting Generac Pressure Washer
Before we start, there are a few things you need to do:
- Make sure that the pressure washer is turned off and all the hoses are disconnected.
- Remove the spark plug from the engine. This will prevent the engine from accidentally starting while you’re working on it.
- Check the oil level in the engine. If it’s low, add more oil until it reaches the full line.
- Fill the gas tank with fresh gasoline. It’s important to use fresh gasoline because it will help your pressure washer run more efficiently.
Now that you’ve done all of that, you’re ready to start your Generac pressure washer! Here’s how you do it:
- Step one: Connect the hose to the water inlet. Make sure that the hose is firmly connected so that there are no leaks. This is important because leaks can cause the pressure washer to lose power and not work properly.
- Step two: Connect the high-pressure hose to the outlet on the pressure washer. Again, make sure that there are no leaks. In addition, be sure to connect the hose securely so that it doesn’t come disconnected while you’re using the pressure washer.
- Step three: Open the water valve all the way. This will allow water to flow through the pressure washer and into the pump. It’s important to open the valve all the way so that the pump doesn’t overheat.
- Step four: Prime the pump by pulling the cord a few times. This will get the water flowing through the pump and get it ready to use. In addition, be sure to keep your hand on the handle so that you don’t accidentally pull the cord out.
- Step five: Start the engine by pulling the cord. The engine should start relatively easily. If it doesn’t, check to make sure that there is gasoline in the tank and that the spark plug is connected.
- Step six: Adjust the pressure using the knob on the pressure washer. This will allow you to control how much water is being sprayed. In general, you’ll want to start with a lower setting and then increase the pressure as needed.
- Step seven: Start washing! Begin by holding the wand at a distance from the surface you’re cleaning. Then, move the wand closer to the surface as needed. Be sure to keep the tip of the wand moving so that you don’t damage the surface.
- Step eight: When you’re finished washing, turn off the engine and disconnect all of the hoses. Make sure that the water valve is closed so that no water can flow through the pressure washer.
- Step nine: Store the pressure washer in a dry, cool place. This will help to extend its life and keep it working properly for years to come.
That’s all there is to it! As you can see, starting a Generac pressure washer is very simple. Just follow the steps above and you’ll be up and running in no time. In addition, be sure to check out our other guides for more tips on how to use your pressure washer.
