Pressure Washer 22

Starting a Husqvarna pressure washer can seem like a daunting task if you’re unfamiliar with the process. However, with the right guidance and understanding of each step, you’ll have your pressure washer up and running in no time. This in-depth guide will walk you through the entire process, from initial setup to troubleshooting common issues.


To start a Husqvarna pressure washer, first ensure it’s properly set up and connected to a water supply. Turn on the water supply and pull the spray gun trigger to get water flowing through the machine. Then, turn the engine switch and fuel supply to the ON position, move the throttle lever to the FAST position, and the choke lever to the CHOKE position. Hold the trigger of the wand open and pull the recoil starter to start the engine. Once the engine has started, you can release the trigger.

Initial Setup

Before you even think about starting your Husqvarna pressure washer, there are several initial steps you need to take.

  1. Positioning: Place the pressure washer near an outside water source capable of supplying water at a flow rate greater than 3.7 gallons (14 liters) per minute and no less than 20 PSI.
  2. Connecting the water supply: Connect a garden hose to the water inlet of the pressure washer. Make sure to flush the hose before connecting it to the pressure washer to remove any debris.
  3. High-pressure hose connection: Check that the high-pressure hose is tightly connected to the pressure washer.
  4. Level Surface: Ensure the unit is on a level position.
  5. Water Supply: Turn on the water supply and pull the trigger on the spray gun to get water flowing through the machine, ensuring water is present in the system before starting the engine.
  6. Engine Switch: Turn the engine switch to the ON (I) position.
  7. Fuel Supply: Move the fuel shut-off lever to the ON (I) position.
  8. Throttle Lever: Move the throttle lever to the FAST ( ) position.
  9. Choke Lever: Move the choke lever to the CHOKE ( ) position.

Starting the Engine

Once you’ve completed these initial steps, you’re ready to start the engine. Here’s how:

  1. Trigger the Wand: Hold the trigger of the wand open, allowing water to run through while you start the engine. This prevents the pump from building pressure and stalling the engine’s rotation.
  2. Start the Engine: Pull the recoil starter to start the engine.

Once the engine has started, you can release the trigger. Make sure to follow the operator’s manual for any specific instructions related to your particular Husqvarna pressure washer model.

Adjusting the Pressure Settings

Adjusting the pressure settings on a Husqvarna pressure washer is quite straightforward:

  1. Choose the appropriate nozzle: Different nozzles have different spray patterns and pressure levels. For example, a 0-degree nozzle provides the highest pressure, while a 40-degree nozzle offers a wider spray pattern and lower pressure.
  2. Attach the nozzle to the spray gun: Pull back the quick-connect collar, insert the nozzle, and release the collar to lock it in place.
  3. Purge air from the system: Turn on the water supply and let water flow through the pressure washer for a few seconds to purge air from the system.
  4. Start the pressure washer engine: Follow the instructions in the user manual to start the engine.
  5. Test the pressure: Squeeze the trigger on the spray gun. The pressure washer motor will start and stop as the spray gun trigger is depressed and released.

Maintenance Tips

Maintaining your Husqvarna pressure washer is crucial for its longevity and optimal performance. Regular maintenance includes changing the engine oil, checking and cleaning the air filter, inspecting the spark plug, cleaning the nozzle, inspecting and replacing hoses and seals, and properly storing the pressure washer.

Troubleshooting Common Issues

If your Husqvarna pressure washer won’t start, there are several common issues you can troubleshoot. These include checking the spark plug, inspecting the fuel, ensuring proper water supply, checking the throttle control, releasing pressure, and clearing air from the system.

Remember to always wear appropriate personal protective equipment, such as safety goggles and gloves, while operating a pressure washer. Avoid pointing the spray gun at people, animals, or delicate objects and never leave the pressure washer unattended while it’s running.

With these steps, you’ll be able to start, use, and maintain your Husqvarna pressure washer effectively and safely. Happy cleaning!
