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 ST203 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.
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 vehicle 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
