How to start a high-pressure washer - step-by-step gude

To get the best performance from your Husqvarna high-pressure washer, it is important to connect it properly to the water supply and bleed the system before use.

Following the correct set-up procedure ensures safety, prevents damage, and delivers optimal cleaning results.

Step-by-step: Starting a high-pressure washer

  1. Connect to a water source.
    Attach your high-pressure washer to a reliable water supply. Ensure the hose is not kinked or blocked.
  2. Bleed the washer.
    Run water through the system to remove any trapped air. This step prevents uneven pressure and protects the pump.
  3. Connect to power.
    Plug the washer's power cord into a suitable power outlet.
  4. Switch on the washer.
    Turn the power switch to the ON (I) position.
  5. Unlock the spray handle.
    Disengage the power trigger lockout for safe operation.
  6. Start cleaning.
    Squeeze the power trigger on the gun/spray handle to begin using your high-pressure washer.



    NOTE: The washer will automatically stop when you release the power trigger.

Pro tips for safe use

  • Always check water connections before powering on.
  • Never tun the washer without water supply - it can damage the pump.
  • Use Husqvarna-approved accessories for the best performance.
