SD314/ SD317 Back Side
A. The oil filling port: The first refill should not exceed a total of 30ML of smoke oil.
Overfilling may result in insufficient internal heating, leading to no smoke or
reduced smoke output. When the smoke oil is nearly depleted and no longer
produces smoke, an additional 10-20ML can be refilled.
B. Air mode switch: Press the air mode switch (AIR MODE) to start the air pump.
Only after this mode is activated can the smoke mode (SMOKE MODE) potentially
start working.
C. Smoke mode switch: Press the smoke mode switch (SMOKE MODE) to start
the smoke. In this mode, if the smoke oil level in the system detector is insufficient
or if the detector operates continuously for too long (approximately 5 to 9 minutes
- 7 -
depending on the specific working environment), causing overheating inside the
detector, the overheat protection indicator light will illuminate until the temperature
returns to the normal range and the detector resumes operation.
D. Pressure gauge: The pressure gauge allows for quick observation and
judgment of whether the tested parts of the vehicle are leaking by indicating the
pressure gauge pointer.
E. Flow gauge (SD314 excluded): After the tested area is filled with smoke or air, if
there is no leakage, you can observe through this window. The flow meter float
remains at the bottom, and the pressure gauge pointer rises. If there is a leak in
the system, the flow meter float rises, and the pressure gauge pointer drops.
F. Flow control knob (SD314 excluded): Adjusts the volume of smoke or air flow.
G. Power indicator light.
H. Overheat indicator light.
I. Input power interface: Insert the power cord here to provide operating power for
the instrument.
J. Smoke outlet port: Smoke is introduced into the car's pipeline system through
the smoke outlet and smoke pipe.
K. Oil drain port: After each use of the equipment, if the device is not used for
about a week, empty the smoke oil to prevent particle deposition, which may affect
the functionality of the equipment. After draining, maintain the internal seal of the
device.
Operation method: Unscrew the oil drain cap (located on the back of the
machine), tilt the machine 30°to let the remaining e-liquid flow out, and then screw
the cap back on.

1. After assembling the leak detector accessories, inject approximately 30ML of
smoke oil for the first use. One injection can work continuously for about 20-30
minutes. Excessive oil injection may result in insufficient internal heating and no or
less smoke output.
2. Open the engine hood and remove the air filter. For some vehicle models, the
airflow sensor may need to be removed.
3. Place the Universal Adapter or Cone Adapter into the engine intake hose port
and seal the pipeline tightly by applying force until the intake hose is sealed (when
using the airbag, the maximum diameter should not exceed 10CM to avoid
damage).
4. Connect the power cord to the car battery. The red alligator clip connects to the
positive pole of the battery, and the black alligator clip connects to the negative
pole of the battery.
5. After connecting power, and the power indicator light will illuminate, indicating
that the smoke leak detector is powered normally. Press the air mode switch (AIR
MODE) to start working. Only after this mode is activated can the smoke mode
(SMOKE MODE) be activated.
6. After starting work by pressing the air mode switch (AIR MODE), pay attention
to the indications of the pressure gauge pointer. If the indication exceeds 15PSI
and the flow gauge float remains stationary at the bottom, it indicates no leakage
detected. If the pressure gauge pointer rises slowly and the flow gauge
continuously detects air inflow (float rises), check whether the access pipeline is
properly connected. After confirming that there are no connection issues, it can be
determined that there is a leakage in the tested system, and then press the smoke
mode (SMOKE MODE) switch.
7. Press the smoke mode (SMOKE MODE) switch to start the smoke. In this mode,
depending on the vehicle model, it will take approximately 1-3 minutes for the
interior to be filled with smoke. Start checking for leakage faults. During this
process, if the smoke oil level of the detector is insufficient or the continuous
working time is too long (about 5-9 minutes depending on the working
environment), causing the instrument to overheat, the overheating protection
- 9 -
indicator light will illuminate and pause the work until the temperature
drops to the normal range, and then the instrument will resume working.
8. During use, if you encounter recoil force, the pressure gauge will show a sudden
abnormality, and the smoke will stop for 1-3 seconds. This is non-continuous and
is normal. After the inspection is complete, unplug the power cord and store the
accessories for next use. The main body of the Universal adapter, Cone adapter
are made of rubber, please avoid contact with corrosive liquids such as gasoline.
9. Use of Universal Adapter: Place the universal adapter at the opening pipe which
needs to be sealed, tighten the metal knob on the bellows clockwise. Then, press
the airbag to be inflating it seals (the maximum diameter of the airbag should not
exceed 10CM). Insert the smoke tube into the airbag hose, causing smoke to enter
the detection pipeline, After the inspection is completed, loosen the metal knob by
turning it to the left to quickly release the air and remove the airbag.
10. When using accessories for leak testing, such as adapter joints, EVAP adapter
joints, or universal conical air inlet adapters, insert the smoke tube into the hose
port causing smoke to enter the detection pipeline, then seal the corresponding
pipe opening on the other end.
The EVAP service port is usually located in the engine compartment, but in some
special vehicle models, the EVAP service port may be located elsewhere. The
conventional method for EVAP detection is as follows: Open the plastic cover of
the EVAP service port, then use a valve core wrench to remove the check valve in
a clockwise direction, and install the EVAP service port adapter. Smoke is then
introduced into the EVAP system through this port for leak detection.
If the leak detector model is equipped with a pressure gauge, you can first not turn
on the smoke switch, block the smoke outlet of the relevant pipeline, and observe
the pressure gauge reading. If the pressure gauge reading continues to rise and
remains steady after stopping the AIR MODE, it indicates that there are no leaks in
the tested area. If the pressure gauge reading decreases after stopping the AIR
- 10 -
MODE, it indicates that there is a leak in the tested area. If the pressure gauge
reading is zero, it indicates that there is a leak, and the size of the leak point
exceeds 0.3 millimeters.
This product can use smoke oil (baby massage oil, skincare glycerin or industrial
glycerin, special oil for automotive smoke machines, mineral oil is not
recommended). The selected smoke oil must be pure and free of water, and must
be in a fluid state. Do not use thick smoke oil, which can easily damage the
instrument. When adding smoke oil, please use the accompanying refueling bottle.
If too much oil is added, please open the oil drain to discharge an appropriate
amount of oil.
After long-term use, smoke oil may oxidize and deteriorate, affecting the working
condition and lifespan of the instrument, so please replace the smoke oil in time.
1. Before adding new smoke oil, pour out all the used smoke oil.
2. If the smoke contains water droplets during use, replace it with new smoke oil.
