Turn off the engine ignition switch.
All leak detection of automobile piping systems must be
performed with the engine turned off.
Remove the air filter. For some models, the throttle needs to be
removed.
Clean the inner wall of the test interface and install the cone
adapter on the test interface.
Install the smoke pipe on the smoke outlet of the host (G) and
plug the power cord into the host power interface (F).
The host is powered by a DC 12V car battery.
When the working indicator light (D) is on, the cone head on
the smoke pipe has air pressure output.
Press the smoke control switch (E) and wait for about 10
seconds. When the smoke becomes thicker, insert the cone
head on the smoke pipe into the cone adapter.
Wait for about 1-2 minutes. You can use a strong flashlight to
help find the leak point of the pipe and judge the leak condition.
After the test is completed, press the smoke control switch (E)
and the host will stop producing smoke.
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.
The pressure gauge of the smoke leak detector serves two
main purposes. First, it is used for product self-testing. By
blocking the smoke outlet and observing the pressure chang-
es, the working status of the main unit can be determined.
Second, it is used for leak detection. Customers can prelimi-
narily assess the leakage in the pipeline system by observing
changes in the pressure gauge needle. If there is a significant
leak in the pipeline, the pressure gauge needle will remain
OPERATIONS INSTRUCTION
Install the hook onto the hook port (A) and hang under the
hood.
Open the filling cap and drain 10ml of test liquid into the filling
port (B).
If the test oil is overfilled, turn the device upside down to drain
some oil.
Start using the SDT202 after the first two steps.
Fit the smoke hose to the smoke outlet (G) and the power cord
to the power socket (F).
Connect the power clip to the DC 12V car battery.
The red clip is connected to the positive terminal (+) and the
black clip is connected to the negative terminal (-). For optimum
performance of the smoke leak detector, the car battery should
be fully charged in advance.
This detector only allows to use DC 12V car battery as power
source.
The built-in air pump starts to work to produce pressurized air
after power on.
Press the smoke control switch (E), the smoke indicator (D)
lights up, the detector starts to work and generates smoke.
When the internal temperature reaches 75°C, the product will
start self-protection function and stop working automatically.
Press the smoke control switch (E) to stop the smoke output.
It is recommended to drain out the remaining test oil for next
use in case the detector is not used for a long time.

stationary. Only when the tested pipeline system has a
relatively small area will the pressure gauge needle rise to a
fixed pressure value. If there is a leak, the pressure gauge
needle will drop or become unstable. In this case, the smoke
switch can be activated to introduce smoke into the pipeline
system, allowing the leak location to be identified and repaired.
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.
Airbag adopter can not contact with corrosive oil.
