operation
during use
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 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.
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.
When the internal temperature reaches 75°C after a long time
using, the protection indicator (E) will light up and the detector
will stop working automatically.
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).
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.
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.
Connect the red clip to the positive terminal (+) and the black
clip to the negative terminal (-). To achieve the best perfor-
mance from the smoke leak detector, the car battery should be
fully charged in advance.
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.
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.
NOTE

NOTE
NOTE
The smoke leak detector pressure gauge has two main
functions, one is for machine self-test, and the other is used for
leak judgment, which can be used to initially determine the
leakage of piping system through the change of pressure
gauge pointer. If the pointer of the pressure gauge keeps still,
which represents there is a relatively serious leak in the
pipeline; the pressure gauge poi nter will rise to a fixed
pressure value only if the area of the piping system currently
being tested is relatively small. And 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.
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.
