Frequently Asked Questions - SD314 Vevor

What type of oil should be used for the Vevor SD314?

Use special smoke oil, baby massage oil, medical glycerin or industrial glycerin. Avoid mineral oil and thick oils.

How to start the SD314 smoke machine?

First, press the AIR MODE switch to start the air pump. Then press the SMOKE MODE switch to produce smoke. Air mode must be activated before smoke mode.

How long does the device run on a full oil charge?

With approximately 30 ml of oil, the device runs continuously for 20 to 30 minutes.

What to do if the smoke becomes weak?

This indicates that the oil is insufficient. Fill quickly with suitable oil via the filling port (do not exceed 30 ml for the first refill).

How to interpret the pressure gauge and flow meter?

If the pressure gauge needle rises and the flow meter float stays at the bottom, there is no leak. If the needle drops and the float rises, there is a leak in the tested system.

What does the overheat indicator mean?

The overheat indicator means the machine has overheated. Smoke production stops until the temperature drops (about 5 minutes). This is normal and the cycle repeats automatically.

How to clean and maintain the leak detector?

After use, especially if the device remains inactive for more than a week, drain the oil through the drain port to avoid deposits. Replace the oil regularly if it oxidizes.

Can I use the machine with the engine running?

No, do not start the engine during the test. Perform tests with the engine off (cold or hot after stopping).

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

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 degrees to let the remaining e-liquid flow out, and then screw the cap back on.

OPERATING METHODS

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 10 cm 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, 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 15 PSI 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

indicator light will illuminate and pause the work until the temperature drops to the normal range, and then the instrument will resume working.

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 Universal adapter, Cone adapter are made of rubber, please avoid contact with corrosive liquids such as gasoline.
2. 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.
3. 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.

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. 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.
