Operating Instructions
1. Starting the Pressure Washer
- With the water supply on and the unit plugged in, press the ON/OFF switch to the 'ON' position.
- Squeeze the trigger on the spray gun to release any air trapped in the system and allow water to flow smoothly.
- The Total Stop System (TSS) will engage when the trigger is released, turning off the pump. The pump will restart when the trigger is squeezed again.
2. Adjusting the Spray Nozzle
The adjustable spray wand allows you to easily change the spray pattern from a pinpoint jet to a wide fan spray. Simply twist the nozzle at the end of the wand to achieve the desired pressure and spray pattern for your cleaning task.

3. Cleaning Techniques
- Always test the spray on an inconspicuous area first to avoid damaging the surface.
- Start with a wider fan spray and lower pressure, gradually increasing as needed.
- Keep the nozzle at a consistent distance from the surface, typically 6-12 inches, and move in even, overlapping strokes.
- For stubborn dirt, consider using a pressure washer-safe detergent (sold separately) in conjunction with the unit.

Troubleshooting

| No water coming from nozzle | Water supply off or restricted; air in pump | Ensure water supply is fully open. Squeeze trigger to purge air from the system. Check water inlet filter for clogs. |
| Low pressure | Clogged nozzle; insufficient water supply | Clean nozzle with needle tool. Ensure garden hose is fully open and not kinked. |
| Unit leaks | Loose connections; damaged O-rings | Tighten all hose connections. Inspect O-rings for wear and replace if necessary. |
