4. Connect Power: Plug the 16.5-foot power cord into a grounded electrical outlet. Ensure the outlet meets the power requirements specified in the 'Specifications' section.
5. Purge Air from System: Before turning on the power, squeeze the trigger on the spray gun to allow water to flow through the system and expel any trapped air. Continue until a steady stream of water emerges.

5. Operating Instructions

5.1. Starting the Pressure Washer

1. Ensure the water supply is connected and turned on, and air has been purged from the system.
2. Turn the power switch on the unit to the 'ON' position.
3. Engage the safety lock on the spray gun, then squeeze the trigger to begin spraying.

5.2. Using Quick-Connect Nozzles

The pressure washer includes four quick-connect nozzles, each designed for specific cleaning tasks. To change a nozzle, pull back the collar on the spray gun's quick-connect fitting, insert the desired nozzle, and release the collar to lock it in place. Always ensure the nozzle is securely attached before operating.

• 0° Red Nozzle (Powerful Jet): Delivers a concentrated, high-impact stream for tough stains, cracks, and metal surfaces. Use with caution as it can damage surfaces.
• 15° Orange Nozzle (Focused Clean): Provides a powerful, narrow spray for intensive cleaning of asphalt, brick, and concrete.
• 25° Green Nozzle (General Use): Offers a versatile, medium-angle spray suitable for general cleaning of decks, fences, and patios.
• 40° White Nozzle (Gentle Spray): Produces a wide, gentle spray ideal for cleaning vehicles, windows, and outdoor furniture.

5.3. Using the Foam Cannon

The 500ml foam cannon is designed for efficient application of cleaning solutions, especially for car washing. Fill the foam cannon with your preferred pressure washer-safe detergent. Attach it to the spray gun's quick-connect fitting. The external foam cannon design prevents detergent from passing through the pump, ensuring safe operation.
