4. Operating Instructions

Once assembled and primed, your Greenworks GPW2005 pressure washer is ready for operation.

4.1 Nozzle Selection

Choose the appropriate quick-connect nozzle for your cleaning task. To change nozzles, pull back the collar on the quick-connect wand, insert the desired nozzle, and release the collar to lock it in place. Always ensure the nozzle is securely seated before operating.

• 25° Nozzle (Green): For general cleaning of most surfaces. Provides a strong, fan-shaped spray.
• 40° Nozzle (White): For gentle cleaning of delicate surfaces or wide area rinsing.
• Turbo Nozzle: Provides a concentrated, oscillating stream for tough stains and heavily soiled areas. Use with caution on delicate surfaces.
• High-Pressure Soap Applicator (Black): For applying detergent. This nozzle operates at a lower pressure to allow for soap application.
