Product Introduction
Overview
AUTOOL SDT206 model is a high-end automotive smoke machine. It is the star of the SDT models range and has been the best seller since its release in 2016 because of its stable performance. It comes with two test modes: Air mode and smoke mode. With the help of air mode, it is possible to diagnose whether there is a leak through the pressure gauge with no need to output smoke. And the smoke mode has an independently controlled smoke generator, which can be activated in case a leak is found, enabling you to locate the leak precisely.
AUTOOL SDT206 model comes with built-in 2 groups of high -power air pumps, no need to purchase additional air pumps or air compressors. There is a visualized oil level gauge that can effectively observe the filling amount and purity of the test oil. Effective observation and control of smoke flow with visual flow meter and adjustable knob. Besides, visualized pressure gauges make it easier and faster to detect leaks.
Any other use is considered beyond the intended purpose of the equipment and is prohibited.
Working Theory
Low Oxygen Combustion
The AUTOOL smoke leak detector employs a forced combustion smoke generation method in a low oxygen environment. It is energized by a conductive column to the heating wire, which rapidly heats up to more than 300°C so that the mineral oil reaches the ignition point and enters the state of combustion. Due to the small intake of air flow, it is insufficient to provide sufficient oxygen to maintain full combustion, thus the combustion mainly occurs on the surface of the heating wire. Subject to high-temperature heating, the mineral oil retention object can continue to burn insufficiently around the heating wire, thus producing a large amount of smoke.

Operations Instruction
Preparation Before Use
- Install the hook onto the hook port (A), hanging under the hood.
- Open the oil filler cap and fill 10ml test oil into the filling port (B). The amount of test oil can be observed through the liquid level gauge (J).
- NOTE: If the test oil is overfilled, please drain some oil out through the oil drain outlet (K).
- After completing the first two steps, start using the SDT206.
Detail Operation During Use
- Connect the smoke hose to the smoke outlet (N) and the power cable to the power interface (L).
- Attach the power cable clips to a DC12V car battery.
- NOTE: Connect the red clip to the positive terminal (+) and the black clip to the negative terminal (-). To achieve the best performance from the smoke leak detector, the car battery should be fully charged in advance.
- NOTE: This device is only allowed to use a DC12V vehicle battery as its power source.
- Press the air mode switch (F) to start generating pressurized air.
- Press the smoke mode switch (G) to start generating smoke.
- NOTE: The smoke output can be controlled using the Smoke Flow Adjustment Valve (I).
- Press the Smoke Mode switch (G) again to stop smoke output.
- If the product is not used for a long time, it is recommended to pour out the remaining smoke oil for storage.
Operation Guidelines for Automobile Pipeline Inspection
- Turn off the engine ignition switch.
- NOTE: All leak detection of automobile piping systems must be performed with the engine turned off.
- Remove the air filter. For some vehicle models, it is necessary to remove the throttle valve.
- Clean the inner wall of the test interface and install the tapered adapter onto the test pipe.
- Install the smoke hose onto the main unit's smoke outlet (N) and plug the power cable into the main unit's power interface (L).
- The product is powered by a DC12V car battery.
- When the air mode switch (F) is pressed, there will be an air pressure output from the smoke hose.
- Press the smoke mode switch (G) to generate smoke. Wait for about 5 seconds, and when the smoke becomes denser, insert the tapered nozzle of the smoke hose into the tapered adapter.
- Wait for about 1-2 minutes and use a strong flashlight to help locate the pipeline leak and assess the leakage condition.
- After the test is complete, turn off both the air mode switch (F) and the smoke mode switch (G) at the same time.
- NOTE: If only part of the system needs to be tested or if the system being tested has other openings that need to be sealed, a plug kit can be used, which can also be used to seal the intake manifold.
Instruction of Smoke Leak Detector Pressure Gauge
The smoke leak detector pressure gauge has two main functions: one is for machine self-test, and the other is used for leak judgment. It can be used to initially determine the leakage of a piping system through the change of the pressure gauge pointer. If the pointer of the pressure gauge keeps still, it represents there is a relatively serious leak in the pipeline. The pressure gauge pointer will rise to a fixed pressure value only if the area of the piping system currently being tested is relatively small. If there is a leak, the pressure gauge pointer will drop or become unstable. In this case, you can turn on the smoke switch to output smoke to locate the leak.
Airbag Adapter Instructions
Airbag adapters are suitable for non-circular connections. For round and oval ports, please use the inlet tapered adapter for normal cases.
- Before using the airbag adapter, be sure to clean the inner wall of the intake manifold (or other test interfaces) to prevent sharp protrusions from piercing the airbag adapter.
- Put the air bag (Z) into the test port.
- Press the hand pump (X) until the bladder (Z) inflates and fully seals the test port.
- Connect the cone head on the smoke outlet pipe with the smoke guide pipe (Y), introduce gases and smoke into the duct to be tested.
- After the test is completed, turn the pressure relief valve (W) counter clockwise, take out the car air inlet adapter from the test port, clean and save it.
NOTE: Airbag adapter cannot contact with corrosive oil.
About Smoke Test Oil
This product needs to use special test oil. It's recommended to purchase liquid paraffin or baby oil as test oil if you cannot find special test oil locally.
It is recommended to use the filling bottle with the capacity mark in the accessories of the packing to fill in new oil.
Too much test oil in the machine can affect smoke output. Please discharge part of the liquid through the oil discharge port.
If the product is not used for a long time, it is recommended to drain out the remaining test oil for preservation.
