6. Operating Instructions
6.1. Powering On/Off
To start the pressure washer, press and hold the trigger on the handle. Release the trigger to stop the water flow. The device is designed for intermittent use; avoid continuous operation for extended periods to prevent overheating.
6.2. Nozzle Selection and Adjustment
The TOPALL TP-01 comes with two primary nozzle types for various cleaning tasks:
- 6-in-1 Multi-Angle Nozzle: This nozzle allows you to quickly switch between six spray patterns by rotating its head. The available patterns are:
- 0° Jet: A concentrated, powerful stream for stubborn dirt.
- 15° Fan: A narrow fan spray for intense cleaning on smaller areas.
- 25° Fan: A medium fan spray for general cleaning.
- 40° Fan: A wide fan spray for gentle cleaning or rinsing large areas.
- Shower: A gentle spray for watering plants or rinsing delicate surfaces.
- Foam: For use with the foam sprayer attachment.
- Rotating Nozzle: This nozzle provides a powerful, oscillating jet for deep cleaning of tough grime and stains. It can be rotated from 0° to 180° to adjust the spray angle.
- Foam Sprayer: Fill the foam sprayer bottle with appropriate cleaning solution. Attach it to the pressure washer in place of a standard nozzle. This creates a rich foam for effective cleaning, especially for vehicles.

6.3. Usage Tips
- Vehicle Washing: Use the foam sprayer for pre-soaking, then a 25° or 40° fan spray for rinsing.
- Patio/Ground Cleaning: The 0° jet or rotating nozzle is effective for stubborn dirt on hard surfaces.
- Garden Irrigation: Use the shower mode for gentle watering of plants.
- Furniture Cleaning: Use a wider fan spray (e.g., 40°) to avoid damaging surfaces.

7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your pressure washer.
- Clean Water Filter: Regularly inspect and clean the water inlet filter to prevent blockages and ensure consistent water flow. Rinse it under running water.
- Rinse Foam Sprayer: After using the foam sprayer, rinse it thoroughly with clean water to prevent residue buildup.
- Drain Water: After each use, disconnect the water source and run the pressure washer for a few seconds to drain any remaining water from the pump and hose. This prevents freezing damage in cold weather.
- Battery Care: Store batteries in a cool, dry place. For long-term storage, charge batteries to about 50% capacity. Avoid fully discharging batteries before recharging.
- General Cleaning: Wipe down the exterior of the pressure washer with a damp cloth. Do not use harsh chemicals.
- Storage: Store the pressure washer and all accessories in the provided carrying box in a dry, protected area, away from direct sunlight and extreme temperatures.
8. Troubleshooting
If you encounter issues with your TOPALL TP-01, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pressure washer does not start. | Battery not inserted correctly or discharged. | Ensure battery is fully charged and securely inserted. |
| Low water pressure. | Insufficient water supply, clogged filter, or blocked nozzle. | Check water source, clean water filter, clear any nozzle blockages. |
| Water leakage from connections. | Loose connections or damaged O-rings. | Tighten all connections. Inspect and replace O-rings if damaged. |
| Motor runs but no water sprays. | Air in the pump or water inlet hose not properly submerged. | Ensure the water inlet hose is fully submerged in the water source. Prime the pump by running it for a few seconds until water flows. |
