6. Operating Instructions
6.1. Connecting Water Supply
Ensure the water source is clean and free of debris. The pressure washer can draw water from multiple sources:
- Faucet Connection: Connect a standard garden hose (not included) to the water inlet connector on the pressure washer and then to a household faucet. Turn on the faucet fully.
- Bucket/Pool Siphon: For off-grid use, the pressure washer can siphon water from a bucket or pool. Ensure the water source is elevated or the hose is primed to allow water flow to the pump.

6.2. Attaching Nozzles
The pressure washer comes with four quick-connect nozzles, each designed for different applications:
- 0° (Red): Pin-point jet for intense cleaning of stubborn stains. Use with extreme caution.
- 15° (Yellow): Narrow spray for heavy-duty cleaning of hard surfaces.
- 25° (Green): Medium spray for general cleaning of most surfaces.
- 40° (White): Wide spray for gentle cleaning or rinsing.
To attach a nozzle, pull back the collar on the spray gun wand, insert the nozzle, and release the collar to lock it in place. Ensure it is securely fastened before operating.

6.3. Adjusting Pressure
The pressure can be adjusted from 2500 PSI to 5000 PSI using the twist-button control on the unit. Start with a lower pressure setting and gradually increase it to prevent surface damage, especially on delicate materials.

6.4. Using the Foam Cannon
Fill the foam cannon's soap bottle with a pressure washer safe detergent. Attach the foam cannon to the spray gun wand. The foam cannon mixes detergent with the high-pressure water to create a thick foam, ideal for pre-soaking vehicles or other surfaces.
6.5. Starting and Stopping
- To Start: Ensure all connections are secure and the water supply is on. Plug the GFCI power cord into a grounded outlet. Turn the ON/OFF switch to the 'ON' position. Squeeze the spray gun trigger to release air and allow water to flow through the system before the pump fully engages.
- To Stop: Release the spray gun trigger. The Total Stop System (TSS) will automatically shut off the pump. For complete shutdown, turn the ON/OFF switch to 'OFF' and unplug the unit.
7. Maintenance and Storage
Proper maintenance ensures the longevity and performance of your pressure washer.
- After Each Use: Disconnect the water supply and power. Squeeze the trigger to release any remaining pressure in the system. Drain all water from the pump, hose, and spray gun to prevent freezing damage.
- Cleaning Nozzles: Clear any blockages from the nozzles using the included nozzle cleaning tool or a thin wire.
- Storage: Store the pressure washer in a dry, frost-free environment. Use the onboard storage for nozzles, hose, and power cord to keep everything organized.
- Pump Protection: For extended storage, especially in cold climates, consider using a pump protector solution.
8. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cord unplugged, GFCI tripped, ON/OFF switch off | Check power connection, reset GFCI, turn ON/OFF switch to ON |
| Low pressure | Insufficient water supply, clogged nozzle, air in pump, incorrect nozzle | Ensure full water flow, clean nozzle, bleed air from system, select appropriate nozzle |
| Water leaks | Loose connections, damaged O-rings | Tighten all connections, inspect and replace O-rings if damaged |
| Motor stops frequently | TSS engaging, overheating | This is normal operation for TSS. If not TSS, allow unit to cool down. |
