AUTOOL SDT103 Smoke Machine Automotive Leak Detector User Manual

1. ການແນະນໍາ ແລະຫຼາຍກວ່າview

The AUTOOL SDT103 Smoke Machine Automotive Leak Detector is a professional tool designed for quickly and accurately diagnosing leaks in various automotive piping systems. This device helps identify issues such as vacuum hose ruptures, idle drift, and air leaks that can lead to poor engine performance, increased fuel consumption, and other operational problems.

The SDT103 is compatible with a wide range of vehicles, including cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks, and speedboats.

• ໄລຍະການທົດສອບກວ້າງ: Capable of performing smoke tests on multiple systems, including EVAP systems, intake systems, cooling/EGR/exhaust systems, crankcase systems, engine sealing, vacuum leaks, and low-pressure turbo leaks.
• External Air Source Required: The SDT103 does not have an internal air pump. It requires connection to an external workshop air source and a 12V vehicle power supply to generate smoke.
• External Flow Meter: Equipped with an external flow meter, allowing for easy control and monitoring of air pressure. This is crucial for preventing pipe damage from excessive pressure and ensuring effective leak detection.
• EVAP System Detection: Specifically designed to work with EVAP service ports found on American cars produced since 1996.
• Overheat & Anti-frost Protection: The device features intelligent protection mechanisms. If the temperature exceeds 75°C, power protection will activate to turn it off. It can also operate normally in temperatures as low as -20°C.

1. ກະກຽມອຸປະກອນ: Ensure the SDT103 is on a stable, flat surface.
2. ຕື່ມນ້ຳມັນຄວັນ: Open the small cap on top of the device and add approximately 20 ml of baby oil (e.g., Johnson's Baby Oil) or dedicated smoke machine fluid. A small measuring bottle is usually provided for this purpose. Do not overfill.
3. ເຊື່ອມຕໍ່ແຫຼ່ງອາກາດ: Connect the output hose from your external air compressor (workshop air source) to the air inlet port on the SDT103.
4. ເຊື່ອມຕໍ່ພະລັງງານ: Connect the 12V power clamps to a 12V vehicle battery. Ensure correct polarity (red to positive, black to negative). A green light on the device will indicate power is supplied.

5. ການດໍາເນີນງານ

1. Activate Airflow: Turn the flow adjustment knob on the SDT103 counter-clockwise to open the airflow.
2. ເປີດ: Switch on the device using the power button located on the rear or control panel.
3. ສ້າງຄວັນ: Press the smoke button. A red light will illuminate, indicating that smoke generation is in progress. Allow approximately 2 minutes for the device to reach its nominal smoke output.
4. Adjust Smoke Flow: Use the flow adjustment knob to regulate the smoke output. The visual flow meter (ball in tube) will indicate the current flow rate (e.g., 1 to 5 L/min). Adjust as needed for the specific test.
5. Perform Leak Detection: Connect the appropriate adapter (e.g., funnel, inflatable bladder) to the system you wish to test (e.g., exhaust, intake, EVAP). Introduce the smoke into the system. Observe for smoke escaping from any cracks, holes, or loose connections, indicating a leak.
6. EVAP System Testing: For EVAP systems, locate the service port (often in the engine compartment). Open its plastic cover, remove the check valve clockwise with a wrench, then install the EVAP service port adapter and introduce smoke.

• Refilling Smoke Oil: When the smoke density decreases or small oil droplets are ejected from the nozzle instead of smoke, it indicates the oil reservoir is low. To refill, always disconnect the air supply first before adding more oil (approx. 20 ml). This prevents oil from gushing out.
• ທໍາຄວາມສະອາດ: Regularly wipe down the exterior of the device with a clean, dry cloth. Ensure all connections are free from dust and debris.

7. ການແກ້ໄຂບັນຫາ

• ບໍ່ມີຄວັນອອກຜົນ:
  • Check if the 12V power supply is correctly connected and providing sufficient current (approx. 3A).
  • Ensure the external air compressor is connected and providing air.
  • Verify that smoke oil has been added to the reservoir.
  • Confirm the flow adjustment knob is open.
• Smoke Output is Weak or Inconsistent:
  • The smoke oil level may be low; refill as per maintenance instructions.
  • Check the air pressure from the external compressor.
• Bubble Remains Blocked (Internal Issue): If the internal bubble (flow indicator) appears stuck after some use, gently tap the machine. This may help dislodge any internal blockages. If the issue persists, contact customer support.
• ອຸປະກອນປິດໂດຍບໍ່ຄາດຄິດ: The device may have activated its overheat protection. Allow it to cool down before attempting to restart. Ensure adequate ventilation during operation.
