5. Configuración
Follow these steps to set up your SDT203 Smoke Leak Detector for operation.
- Fill with Test Oil:
Unscrew the oil filler cap on top of the device. Using the provided funnel, inject 20-30ml of fresh mineral oil or baby oil into the machine. Do not overfill. Replace the cap securely.

- Connect Smoke Duct:
Attach the smoke output hose to the smoke outlet port on the device. Ensure a secure connection.
6. Instrucións de funcionamento
Once set up, you can begin the leak detection process.
- Preparar o sistema:
Disconnect the pipe or system component that needs to be tested from the vehicle. Seal off any open ends of the system not being tested to create a closed environment for smoke injection. - Turn On Smoke Generation:
Flip the smoke switch on the device to the 'ON' position. The Smoke LED will illuminate, and the device will begin generating smoke. Smoke output should be visible within 30 seconds.
Figure 6.1: Smoke Output
- Adjust Flow Meter:
Use the flow control valve to adjust the smoke output rate. The external flow meter allows you to monitor the flow, which is crucial for different pipe systems that may require varying air pressures. Adjusting the flow prevents damage from excessive pressure and ensures effective leak detection.Video 6.1: Demonstration of SDT203 Leak Detector in use, showing pressure gauge display, smoke output, intake system test, and adjustable flow meter.
This video demonstrates the setup and operation of the SDT203, including connecting power, attaching the smoke duct, observing the pressure gauge, and adjusting the flow meter for effective leak detection in an intake system.
- Inject Smoke:
Insert the smoke output nozzle into the system being tested. The system will fill with smoke. - Locate Leaks:
Observe the system for visible smoke escaping from any points. The external pressure gauge can also help: if the pressure drops significantly or does not build up, it indicates a leak. Repair the identified leak points. - EVAP System Detection:
For American cars produced after 1996, locate the EVAP service port (usually in the engine compartment). Use a spool wrench to remove the check valve clockwise, then install the EVAP service port adapter. Introduce smoke from this port into the EVAP system to detect leaks.

The SDT203 is suitable for a wide range of vehicles, including cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks, and speedboats.
7. Mantemento
Proper maintenance ensures the longevity and optimal performance of your SDT203 Smoke Leak Detector.
- Nivel de aceite: Regularly check the oil level using the oil level gauge. Refill when low to prevent dry burning.
- Limpeza: After use, wipe down the exterior of the device with a clean, dry cloth.
- Almacenamento: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Ensure all hoses and accessories are neatly stored to prevent damage.
- Tipo de aceite: Always use the recommended test oil (mineral oil or baby oil). Using incorrect oil can damage the heating element or pump.
8 Solución de problemas
If you encounter issues with your SDT203, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen saída de fume | Low or no test oil Potencia non conectada Smoke switch off | Refill test oil Check 12V power connection Turn smoke switch ON |
| Sen lectura de presión no manómetro | System not sealed Mangueira desconectada Internal pump issue | Ensure all openings are sealed Check smoke hose connection Contact support if pump fails |
| Cannot find leak | Insufficient smoke time Caudal demasiado baixo Leak is very small | Allow more time for smoke to fill system Increase flow rate with control valve Use a bright light to inspect closely |
| Device overheats and shuts off | Uso continuado prolongado Ventilación deficiente | Permitir que o dispositivo se arrefríe Ensure adequate airflow around device |
