4. Operating Instructions
Once the pressure washer is set up, follow these guidelines for effective and safe operation.
Adjusting Pressure
The pressure washer allows for adjustable pressure between 2,500 PSI and 5,000 PSI. Always start with a lower pressure setting and gradually increase it to avoid damaging delicate surfaces. The pressure control dial is located on the unit.

Nozzle Selection and Application
The pressure washer comes with four quick-connect nozzles and a foam cannon, each designed for specific tasks:
- 0° Red Tip: Delivers a concentrated, high-pressure stream for stubborn stains on hard, durable surfaces like concrete or metal. Use with caution.
- 15° Yellow Tip: Provides a powerful, narrow spray for intensive cleaning of hard surfaces such as brick and concrete.
- 25° Green Tip: Offers a medium-pressure, wider spray suitable for general cleaning of wood decks, siding, and other softer surfaces.
- 40° White Tip: Produces a wide, low-pressure spray ideal for delicate surfaces like windows, screens, and vehicles.
- Foam Cannon: Use with detergent to create rich foam for car washing or other cleaning applications.

Smart Shutdown (Total Stop System)
The pressure washer is equipped with a Total Stop System (TSS). When the spray gun trigger is released, the pump automatically shuts off, conserving energy, reducing noise, and extending the life of the pump. The pump will restart when the trigger is pressed again.
Safety Lock
Always engage the safety lock on the spray gun when not actively spraying to prevent accidental discharge.
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pressure washer.
After Each Use
- Flush the System: Disconnect the detergent tank (if used) and run clean water through the system for a few minutes to remove any chemical residue.

- Wipe Down: Clean the exterior of the unit with a damp cloth.
Storage
