Important Safety Information
Always disconnect the pressure washer from the power supply and water source before performing any maintenance, installation, or replacement of parts. Wear appropriate personal protective equipment, including eye protection, when working with pressure washers and their accessories. Ensure all connections are secure to prevent leaks and accidental disconnections during operation.
Compatibility
This 90-degree replacement nozzle is exclusively designed for use with the following Sun Joe Electric Pressure Washer models:
- Sun Joe SPX2003-SJH Series Electric Pressure Washers
- Sun Joe SPX2004 Series Electric Pressure Washers
Using this nozzle with incompatible pressure washer models may result in improper function or damage.
Installation Guide
- Preparation: Ensure your Sun Joe pressure washer is turned off, unplugged from the power outlet, and disconnected from the water supply. Release any residual pressure in the system by squeezing the trigger gun.
- Remove Existing Nozzle (if applicable): If replacing an old nozzle, firmly grasp the existing nozzle and twist it counter-clockwise to detach it from the spray wand or gun.
- Attach New Nozzle: Align the new Sun Joe SPX2004-90DEG 90-degree nozzle with the end of your pressure washer's spray wand or gun. Push it in firmly and twist clockwise until it clicks securely into place. Ensure it is fully seated and does not wobble.
- Check Connection: Gently tug on the nozzle to confirm it is securely attached. A loose connection can lead to leaks or the nozzle detaching during use.
- Test: Reconnect the water supply and power to your pressure washer. Briefly run the pressure washer to check for any leaks around the nozzle connection point.

Operating the 90-Degree Nozzle
Once installed, the 90-degree nozzle allows you to direct the high-pressure spray at an angle, making it ideal for cleaning hard-to-reach areas such as undercarriages of vehicles, gutters, wheel wells, or the underside of lawnmowers. Simply aim the nozzle and activate your pressure washer as you normally would.
Note: The 90-degree angle provides a concentrated spray pattern. Always maintain a safe distance from the surface being cleaned to avoid damage, especially on delicate materials.
Maintenance
To ensure optimal performance and longevity of your 90-degree nozzle:
- Rinse After Use: After each use, rinse the nozzle thoroughly with clean water to remove any dirt, debris, or chemical residues.
- Inspect for Clogs: Periodically check the nozzle opening for any blockages. If clogged, use a small pin or the included nozzle cleaning tool (if provided with your pressure washer) to clear the obstruction.
- Store Properly: Store the nozzle in a clean, dry place away from extreme temperatures.
- Check for Wear: Inspect the nozzle for any signs of wear, cracks, or damage. A worn nozzle can affect spray pattern and pressure. Replace if damaged.
