4. Setup and Assembly
Follow these steps to assemble your pressure washer before first use.

Figure 4.1: Installation Steps. This visual guide demonstrates the six key steps for setting up the pressure washer: attaching the wand to the spray gun, connecting the high-pressure hose to the spray gun, connecting the high-pressure hose to the pressure washer unit, connecting the garden hose to the water inlet, turning on the water supply, and finally, plugging the power cord into an electrical outlet.
- Attach the Spray Gun and Wand: Connect the stainless steel wand to the spray gun. Ensure it clicks securely into place.
- Connect High-Pressure Hose: Attach one end of the high-pressure hose to the spray gun and the other end to the high-pressure outlet on the pressure washer unit. Tighten connections firmly.
