Dual Mode 
No need to buy extra air compressor !
Air Mode: Air mode can help you test whether there is a leak in the pipe by injecting air into the pipe, and judge by the sound made when the air leaks. Own a S300 air conditioning leak detector, you don't have to buy additional air compressor or air pump, which makes your diagnosis easy and cost-effective.
Smoke Mode: Smoke mode help you lacate the leak accuarately through the visible smoke. The smoke can be produced within seconds, dramatically reducing diagnostic time.

BUILT IN AIR PUMP

No air compressor needed. Just connect staright to your vehicle's 12V battery and generate smoke in seconds!

Pressure Gauge 
No Leak: When the value of the pressure gauge remains unchanged, it indicates that there is no leakage in the system.
Small Leak: When the value of the pressure gauge drops, it indicates a small leak in the system.
Massive Leak: When the value of the pressure gauge reaches zero, it indicates a massive leak in the system.

Adjustable Flow Meter

Air Flow meter with ajustable button, easy to control the smoke effect(output flow:<7L/Min) 

Wide Coverage 

Suitable for all domestic cars, motorcycles, snowmobiles, off-road vehicles, beaches. Cars, light trucks and speedboats, etc. Using together with automotive diagnostic tool, you can find the vehicle problem accurately and diagnose fault.

How to do leakage test？

1. Turn OFF the ignition of the vehicle.
LEAK TEST OF VEHICLE SYSTEMS REQUIRES THE ENGINE TO BE OFF
2.Dismantle the air filter and the throttle connections.
3.Clean the inner wall of the intake opening to avoid sharp objects and put the Universal Intake 
Adapter into the opening
4.Connect the Power Cord to 12V vehicle battery.
5.Now the Power LED would be ON, if else check the power supply.
6.Introduce the smoke nozzle into the system via the Adapter Cone
7.Press Air Control Switch, wait for 30 seconds until the system is pressurized, and check the 
Pressure Gauge & Flow Meter reading for leak status, if the unit is equipped with Pressure Gauge & Flow Meter
8.Press Smoke Control Switch, .unplug and Plug back the smoke nozzle back into the Cone Adapter when there’s obvious smoke coming out of the smoke nozzle
9.The system will be ready for leak check in 2 minutes. Use a bright light torch or working lamp to assist
10.After test, press Smoke Control Switch again to stop the unit from generating smoke and 
press Air Control Switch to stop generating pressurized air
11.Collect the Smoke Hose and the Power Cord with the Velcro Straps for storage. Hang the unit or make it stand in UPRIGHT position only. Do NOT lay it down.

Smoke Oil Choose
The equipment is compatible with mineral oil based baby oil like Johnson & Johnson Pink bottle. Pure #5 white oil is the best choice if available.

Caution !!!

1.When you use this FOXWELL SD203 Car Smoke Leak Detector for the first time, fill with 20ml oil . Please be careful NOT to beyond this range. 

2.The testing liquid : both liquid paraffin and baby oil are OK.

3.Fresh oil can be filled with only when the smoke gets thin, and it can’t be filled over 20ml each time.

4.Before filling fresh oil, please pour out the left oil in the detector & replace the detector oil regularly.

5.During the process of leak detection, please keep away from smoke-sensitive parts.

6.Do NOT run the detector over 8 minutes continuously. It needs interval rest.

7.The detector has an intelligent protector, if it exceeds the working limit, such as over 75 ℃, it will automatically turn off the power. In this case, please operate it later. 

8.The round part of this detector has temperature, please be careful to avoid burns.

9.If the test pipe needs to be disconnected in the middle, please secure the other side with a rubber stopple.

10. Please do not fill full the test oil when the test to avoid oil leakage and splashing. Just pour in two thirds of the test oil.

Specifications
Power source: 12V fully charged vehicle battery
Current: 6A
Flow rate: < 7 LPM
Pressure output: 0.8~1.0 bar

Warning !!!

- Operator shall have basic knowledge about structure of vehicle and the engine. Vehicle service book is required.

- To ensure better test result, it’s required there’s no wind in the operating area.

- Do NOT use the product on smoke sensitive component. Eg. Smoke residual might reduce sharpness of head lights if apply to head light housing.

- ONLY low density mineral oil based fluid is allowed to use as smoke oil. Johnson&johnson’s baby oil(pink label) is compatible. Use funnel to avoid spread the oil to other parts of the unit.

- Check oil level before use, if oil level is lower than the middle of the gauge, the unit would need a refill, but do not overfill the unit beyond the gauge.

- The product is only allowed to use while ignition’s off.  Be sure to use 12V vehible battery, and the battery shall be full charged and voltage not lower than 12V.

- Use bright light torch/ halogen light to help find the leaks.
Wear goggles if available
