Use liquid paraffin or baby oil purchased locally as the testing oil.Add 10-15ml OnlyFill 10-15ml testing oil before use. Do not overfill, and do not add more than 15ml each time.Open Airflow RegulatorBefore use, gently turn the knob to open the airflow regulator valve and prepare the air path for testing.Refill Only When Smoke Is ThinAdd fresh oil only when the smoke becomes thin. Pour out remaining oil before adding fresh oil and replace detector oil regularly.8-Minute Use LimitDo not run the detector continuously for more than 8 minutes. Let the unit rest between test cycles.75℃ ProtectionIf the working temperature exceeds 75℃, the intelligent protection system automatically shuts down power. Wait until the unit cools before using it again.Hot Surface WarningThe round metal section of the detector can become hot during operation. Avoid direct contact to prevent burns.A/C System BoundaryDo not use the smoke leak detector to directly pressure-test an automotive A/C high-pressure system. Use only for segment-assisted checks under proper conditions.Safety ReminderKeep the smoke output away from smoke-sensitive parts during leak detection.Do not refill test oil while the detector is running.If the machine enters protection mode, wait for the temperature to drop before restarting.Use the correct adapter and mode for the test area to reduce the risk of pipe damage.Key FeaturesKey FeaturesSDT208 is designed for efficient professional leak detection with fast smoke generation, a built-in air pump, dual pressure modes, pressure and flow monitoring, EVAP protection, and reliable workshop safety functions.Fast Smoke OutputThe smoke generator produces smoke within seconds under proper setup, helping reduce diagnostic time during pipe leak checks.Built-In Air PumpNo additional air pump is required. The built-in pump saves setup time and makes the detector suitable for shop and mobile automotive repair use.Air Mode And Smoke ModeThe SDT208 integrates an air pump and smoke generator, allowing users to switch between air testing and smoke leak detection according to the test requirement.Standard And EVAP ModesStandard Mode supports up to 35psi, while EVAP Mode is limited below 10psi to better protect vehicle pipes during EVAP testing.Flow Meter And Pressure GaugeThe air flowmeter, airflow control valve, and pressure gauge help control the test pipeline and identify possible leakage by pressure and flow changes.Professional EVAP DetectionThe EVAP mode meets common repair shop EVAP test needs, supports tiny leak checks down to about 0.5mm, and uses pressure protection to help protect vehicle pipes.Overheat And Anti-Freeze ProtectionThe intelligent protection device shuts off power above 75℃ and the unit can work in low-temperature conditions down to -20℃.Wide Vehicle CoverageSuitable for many 12V / 24V leak testing scenarios, including cars, motorcycles, snowmobiles, ATVs, off-road vehicles, light trucks, and speed boats.3-Year Warranty SupportAUTOOL provides 3-year support for eligible non-human damage cases, including product setup, accessory confirmation, and troubleshooting support.

What Testing Oil Should I Use For SDT208? Testing oil is not included due to logistics restrictions. If professional test oil is not available, buy liquid paraffin or baby oil locally and use it as the testing oil. How Much Testing Oil Should I Add? Add 10-15ml testing oil before use. Do not add more than 15ml each time. Refill only when the smoke becomes thin, and drain the remaining test oil before adding fresh oil. If too much oil is added accidentally, drain some oil out before operation. What Power Supply Does SDT208 Need? SDT208 requires a DC 12V or DC 24V battery power supply. Connect the detector correctly before turning on the machine. Can SDT208 Detect EVAP System Leaks? Yes. SDT208 can be used for EVAP leak checks. Use EVAP Mode and choose the proper EVAP testing tools and adapters according to the package contents and the vehicle test port. What Is The Difference Between Standard Mode And EVAP Mode? Standard Mode supports testing up to 35psi for suitable low-pressure systems. EVAP Mode is limited below 10psi to help protect EVAP pipes during testing. Always select the mode according to the system being tested. Can SDT208 Directly Test Automotive A/C System Leaks? No. The automotive A/C system operates at about 1.7-3.0MPa output pressure, while smoke leak detectors generate much lower pressure. SDT208 cannot directly pressure-test the automotive A/C system for leaks. It can only be used for segment-assisted air-conditioning pipeline checks under proper conditions. How To Use Smoke For Segmental A/C Pipeline Auxiliary Testing? First pressurize the air-conditioning pipeline using the proper method, then spray smoke and observe whether airflow blows or disturbs the smoke. If the smoke is disturbed by airflow, that area may indicate a leak point for further repair. What Systems Can SDT208 Test? SDT208 supports low-pressure leak checks for EVAP systems, intake pipes, exhaust pipes, crankcase systems, fuel tanks, pipe fittings, vacuum lines, vehicle sealing areas, and selected turbo or intercooler low-pressure paths under proper conditions. How Do I Read The Pressure Gauge And Flow Meter? The pressure gauge and flow meter help you monitor the test pipeline. In general, if the pressure gauge continues to rise and stabilize, the tested pipeline may have no obvious leak. If the pressure continues to decrease, the pipeline may have a leak that needs further inspection and repair. Can The Pressure Of SDT208 Be Adjusted? SDT208 provides Standard Mode and EVAP Mode, plus airflow adjustment through the regulator. It is not designed as an arbitrary high-pressure tester. Use the correct mode and avoid applying smoke pressure to systems that are not suitable for smoke testing. What Accessories Are Included? Refer to the Packing List image for the final package contents. The SDT208 package image shows the main unit, power cable, smoke hose, adapters, rubber caps, oil bottle, manual, warranty information, certificate, retail box, and accessories shown in the package image. Testing oil is not included. What Should I Check If The Smoke Becomes Thin Or No Smoke Appears? First check whether the detector has 10-15ml testing oil, whether the power supply is connected, whether the airflow regulator is open, and whether the correct switch or mode is selected. If smoke becomes thin, drain remaining oil and add fresh testing oil. If the detector has overheated, wait for it to cool before restarting. Contact support if the issue remains. What Is The Difference Among AUTOOL Smoke Leak Detector Models? The AUTOOL smoke leak detector series includes SDT101 and SDT103 for EVAP systems around 3.2kPa, SDT106 and SDT202 for beginner-level testing around 12psi, and SDT203, SDT205, SDT205S, SDT206, and SDT MASTER as standard or higher-end models around 15psi depending on configuration. SDT208 supports up to 35psi in Standard Mode and below 10psi in EVAP Mode.
