Follow these steps to properly set up your Greenworks pressure washer before first use.
- Attach High-Pressure Hose: Connect one end of the 20-foot high-pressure hose to the outlet on the pressure washer unit and the other end to the spray gun. Ensure connections are secure.
- Connect Water Supply: Attach a standard garden hose (not included) to the water inlet on the pressure washer. Ensure the garden hose is free of kinks and has a minimum diameter of 5/8 inch. Turn on the water supply fully.
- Attach Spray Wand and Nozzle: Insert the rugged wand into the spray gun and twist to secure. Select the desired nozzle tip (25-degree or 40-degree) and push it firmly into the quick-connect coupler at the end of the wand until it clicks into place.

- Connect to Power: Plug the 35-foot power cord with the inline GFCI into a grounded 120V AC electrical outlet. Press the "RESET" button on the GFCI plug if necessary.
- Prime the Pump: Before turning on the unit, 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 from the nozzle. This helps protect the pump.
5. Operating Instructions
Once setup is complete, you can begin operating your pressure washer.
Starting the Unit:
- Ensure water supply is fully open and the pump is primed.
- Turn the power switch on the pressure washer unit to the "ON" (I) position. The motor will start briefly to pressurize, then shut off. This is normal operation for the Auto Start/Stop feature.
- When the trigger on the spray gun is squeezed, the unit will turn on. When the trigger is released, the unit will shut off and enter standby mode.
Using Nozzle Tips:
The pressure washer comes with two quick-connect nozzle tips for different cleaning applications:
- 25-Degree Nozzle (Green): Provides a high-pressure, medium-angle spray, suitable for general cleaning of most surfaces like concrete, brick, and siding.
Figure 4: The 25-degree nozzle provides a focused spray for general cleaning.
- 40-Degree Nozzle (White): Provides a medium-pressure, wide-angle spray, ideal for delicate surfaces, rinsing, or covering larger areas quickly.
Figure 5: The 40-degree nozzle offers a wider, gentler spray for broader coverage.
Using the Soap Applicator:
For applying detergent, use the included soap applicator bottle.
- Fill the soap applicator bottle with pressure washer safe detergent.
- Attach the soap applicator to the spray gun.
- The pressure washer will automatically draw detergent when operating at low pressure. Apply detergent to the surface, allowing it to soak as recommended by the detergent manufacturer.
- After applying detergent, remove the soap applicator and reattach a nozzle tip to rinse the surface with clean water.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
After Each Use:
- Flush System: Disconnect the detergent bottle (if used) and run clean water through the system for a few minutes to flush out any remaining detergent or debris.
- Disconnect Water and Power: Turn off the pressure washer, turn off the water supply, and unplug the power cord.
- Release Pressure: Squeeze the spray gun trigger to release any residual pressure in the system.
- Clean Nozzles: Use the included nozzle cleaning tool (if applicable) or a small wire to clear any blockages from the nozzle tips.
- Store Properly: Store the pressure washer in a dry, frost-free area. Drain all water from the pump, hose, and spray gun to prevent freezing damage.
Seasonal Maintenance:
- Winterization: If storing in an area where temperatures may drop below freezing, use a pump protector or non-toxic antifreeze solution to prevent internal damage. Follow the pump protector product instructions.
- Inspect Hoses and Connections: Periodically check the high-pressure hose, garden hose connection, and spray gun for any signs of wear, cracks, or leaks. Replace damaged components immediately.
