5. Operating Instructions
Once assembled, follow these steps to operate your WHOLESUN pressure washer.
- Prepare Water Supply: Turn on the water faucet completely to ensure a steady flow to the pressure washer.
- Purge Air from System: Squeeze the trigger on the spray gun for approximately 30 seconds without the motor running to allow air to escape and water to flow through the system.
- Connect Power: Plug the GFCI into a suitable electrical outlet. Press the reset button on the GFCI if necessary.
- Select Nozzle: Choose the appropriate quick-connect nozzle for your cleaning task (refer to Section 6). Pull down the metal ring on the lance, insert the desired nozzle, and release the ring to secure it.
- Unlock Spray Gun: Disengage the safety lock on the spray gun.
- Start Cleaning: Aim the spray gun at the surface to be cleaned, maintaining a safe distance, and squeeze the trigger. The motor will start, and high-pressure water will be discharged.
- Engage TSS: Releasing the trigger will activate the Total Stop System, shutting off the pump and motor.
- Apply Detergent (Optional): If using the detergent tank, fill it with pressure washer-safe detergent. Attach the soap nozzle to the lance. The pressure washer will automatically draw detergent when the soap nozzle is in use.

6. Nozzle Selection Guide
Your pressure washer includes 5 quick-connect nozzles, each designed for specific cleaning tasks. Choose the appropriate nozzle to prevent damage to surfaces and achieve optimal cleaning results.
| Nozzle Color | Spray Pattern | Application |
|---|---|---|
| Red (0°) | Pencil-point jet | For extremely stubborn dirt and grime. Use with extreme caution on small, concentrated areas. Not recommended for most surfaces. |
| Yellow (15°) | Narrow fan spray | For intensive cleaning of hard surfaces like concrete, brick, or metal. Effective for removing paint or rust. |
| Green (25°) | Medium fan spray | General cleaning of most surfaces, including siding, decks, patios, and vehicles. Provides a good balance of power and coverage. |
| White (40°) | Wide fan spray | For light cleaning of delicate surfaces, rinsing, or covering large areas quickly. Suitable for windows, cars, and boats. |
| Black (Soap) | Low-pressure wide spray | Used for applying detergent or cleaning solutions. Activates the detergent tank for soap application. |

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- Filter Cleaning/Replacement: Regularly inspect and clean or replace the water inlet filter to prevent debris from entering the pump.
- Hose and Connection Inspection: Before each use, check all hoses and connections for signs of wear, damage, or leaks. Replace any damaged components immediately.
- Storage: After each use, drain all water from the pump, hoses, and spray gun to prevent damage, especially in freezing temperatures. Store the unit in a dry, protected area.
- Cleaning Pin: Use the provided cleaning pin to clear any blockages in the nozzle tips.
8. Troubleshooting
Refer to the following common issues and their solutions. For problems not listed here, contact customer service.
| Problem | Possible Cause | Solution |
|---|---|---|
| High-pressure hose leaking or 'popping' | Improper connection; hose not fully seated or protective layer obstructing connection. | Ensure all connections are tight. If a rubber protective layer is present, carefully cut it to allow for a full, secure connection. |
| Nozzles cannot be installed | Metal ring on the lance not pulled down sufficiently. | Pull down the metal ring on the lance completely before inserting the nozzle. Release the ring to lock the nozzle in place. |
| No pressure or low pressure | Insufficient water supply; clogged inlet filter; air in the system; incorrect nozzle. | Ensure water faucet is fully open. Clean the inlet filter. Purge air from the system by squeezing the trigger without power. Select a narrower nozzle. |
| Motor runs but no water flow | Water supply off; clogged hose/nozzle; air in pump. | Check water supply. Clear any blockages. Purge air from the system. |
