5. Operating Instructions
5.1 Powering On and Off
To turn on the pressure washer, ensure it is connected to a water source and power outlet, then flip the main ON/OFF switch. The unit features a Total Stop System (TSS) which automatically shuts off the pump when the trigger is not engaged, saving energy and prolonging pump life. The pump will restart when the trigger is pulled again.
5.2 Using Interchangeable Nozzles
The pressure washer comes with 4 color-coded quick-connect nozzles, each designed for specific cleaning tasks:
- 0° Red Nozzle: Delivers a concentrated, high-pressure stream for tough, stubborn stains and crevices. Use with extreme caution.
- 15° Yellow Nozzle: Provides a powerful, narrow spray for intense cleaning of hard surfaces like concrete and brick.
- 25° Green Nozzle: Offers a medium-pressure, wider spray for general cleaning of painted surfaces, fences, and siding.
- 40° White Nozzle: Produces a wide, gentle spray for delicate surfaces, windows, and light washing.
Different nozzle types provide various spray patterns for diverse cleaning needs.
5.3 Using the Foam Cannon
For enhanced cleaning, especially on vehicles, attach the foam cannon. Fill the detergent bottle with appropriate pressure washer detergent, then connect it to the spray gun. The foam cannon mixes detergent with water to create a thick foam, which helps loosen dirt and grime before rinsing.

6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
- After Each Use: Flush the system with clean water to remove any detergent residue.

- Storage: Store the pressure washer in a dry, frost-free area. Disconnect all hoses and drain any remaining water from the pump and hoses.
