A. Hooks, convenient for quick fixing of equipment on the car. When using the hook hanger, please pay attention to tighten the nuts on it, so as to avoid the hook and the body rotating multiple times, causing the body to detach and fall and damage.

B. The oil filling port: The first refill should not exceed a total of 30ML of smoke oil. Overfilling may result in insufficient internal heating and thus no smoke or reduced smoke output. When the smoke oil is nearly depleted and no longer produces smoke an additional 10-20ML can be added.

C. Pressure gauge (SD303 not included): 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.

D. Overheating indicator light.

E. Smoke flow control Knob (SD303 SD304 not included): Adjusts the flow of smoke.

F. Air/smoke mode switch: Set to AIR to start the air mode with the air pump working. Set to SMOKE to start the smoke mode. In this mode, if the smoke oil in the instrument is insufficient or if the instrument works continuously for too long (approximately 5 to 9 minutes depending on the specific working environment), causing overheating inside the instrument, the overheating protection indicator light will illuminate until the temperature returns to the normal range and the

instrument resumes operation.

G. Power indicator light: After powering on, the power indicator light illuminates, indicating that the smoke generator is powered normally.

H. Smoke outlet port: Smoke is introduced into the car's pipeline system through the smoke outlet and smoke pipe.

I. Input power interface: Insert the power cord here to provide operating power for the instrument.

J. Flow gauge: 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.

OPERATING METHODS

1. After assembling the leak detector accessories, inject approximately 30ML of smoke oil for the first use. One refilling can continuously operate for about 20-30 minutes. Overfilling may result in insufficient internal heating, leading to no smoke or reduced smoke output.

2. Open the engine hood and remove the air filter. Some vehicle models may require removal of the airflow sensor.

3. Place the Universal Adapter or Cone Adapter into the engine intake hose to block the pipeline. Press firmly until the intake hose is sealed (when using the airbag, ensure that the maximum diameter does not exceed 10CM to avoid

damage).

1. Connect the power cord to the car battery. Attach the red alligator clip to the positive terminal of the battery and the black alligator clip to the negative terminal of the battery.
2. After powering on, the power indicator light ≈ illuminates, indicating that the smoke leak detector is powered normally. It defaults to AIR mode, and the air pump starts working.
3. Press the SMOKE button to switch to smoke mode. After starting, observe the pressure gauge pointer. If the pressure exceeds 15PSI (SD303 without) and the flow gauge (SD307 only) float remains at the bottom, no leaks are detected. If the pressure gauge pointer indicates a very slow pressure rise or no further rise (SD303 without), and the flow gauge monitoring indicates continuous air inflow (float rises), check if the connecting hoses are properly connected. If the connections are correct, it indicates a leak in the tested system. Locate the leak point by observing where smoke escapes.
4. Start the smoke mode. In this mode, approximately 1-3 minutes will be required to fill the internal system with smoke, depending on the vehicle model. Begin checking for leak faults during this process. If during this process, the smoke oil in the detector is insufficient or if the detector operates continuously for too long (approximately 5 to 9 minutes depending on the specific working environment),

causing overheating, the overheating protection indicator light 📄 will illuminate,

and the operation will pause until the temperature returns to the normal range, at which point the detector will resume operation.

1. 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 air inlet adapter is made of rubber, please avoid contact with corrosive liquids such as gasoline.
2. Use of Universal Adapter (SD303 not included): 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.

1. When using accessories for leak testing, such as Pipe adapter, EVAP adapter, or Cone 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.

DRAINING THE OIL

After each use of the equipment, if the equipment will not be used for about a week, empty the smoke oil to prevent the deposition of particles, which may affect the functionality of the equipment. After draining, keep the interior of the equipment sealed.

Operation method: Unscrew the cap of the smoke oil filling port at the top of the smoke generator, invert the whole machine upside down to let the remaining smoke oil flow out, and then screw the cap back on.

EVAP SYSTEM DETECTION METHOD

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.

JUDGMENT OF LEAKAGE CONDITIONS

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 (SD303 not included). 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 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.

ABOUT SMOKE OIL

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.

MAINTENANCE

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.
