Process Automated & Super Easy To Operate!!!

I recently acquired the AUTOOL LM708 Fully Automatic Machine for HVAC automotive recovery and recharge (designed for both R134 and HFO1234yf), and I must say it has exceeded all my expectations. Over the course of roughly thirty operational cycles, this machine has demonstrated exemplary reliability, operating flawlessly without even the slightest hiccup. Its robust construction and precision-engineered components inspire confidence; there has been no indication of leakage or mechanical compromise whatsoever. Beyond its mechanical resilience, the AUTOOL LM708 truly shines when it comes to user-friendliness. The interface is so intuitively structured and straightforward that even my children could navigate its functions—making it equally accessible for technicians of varying skill levels. The step-by-step automation streamlines the entire recovery and recharge process, minimizing the risk of user error and expediting workflow. It’s both refreshingly simple to set up and remarkably efficient to operate, which translates into valuable time savings in a professional garage environment.

Service R134a and R1234yf Vehicles From Separate Circuits

The LM708 keeps R134a and HFO-1234yf in independent circuits and tanks, runs recovery, evacuation, a pressure/vacuum-hold check and recharge in sequence, and prints the job record. It does not identify refrigerant, so confirm the gas before connecting.

  • Independent Dual Circuits
  • 5 Electronic Scales
  • 7-Inch Touchscreen
  • LP / HP / HP+LP Charging
  • Built-In Printer

Key Features

  1. Independent Dual-Refrigerant Systems

    Separate R134a and HFO-1234yf circuits and onboard tanks reduce tank changes and the risk of cross-contamination.

  2. Automatic Configured Workflow

    After the parameters are preset, the station runs recovery, evacuation, the hold check and recharge in order with touchscreen prompts.

  3. Separate Fluid Weighing

    Individual scales weigh the R134a tank, HFO-1234yf tank, PAG oil, POE oil and used oil.

  4. Vehicle Database or Custom Data

    Start setup from the built-in vehicle data or enter custom values, then verify them against the vehicle label and current OEM information.

  5. Protected New-Oil Storage

    The oil-bottle design limits new oil’s exposure to air and moisture, with separate PAG, POE and used-oil positions.

  6. Recovered-Refrigerant Cleaning

    A filter and separator clean recovered refrigerant for reuse when its condition, the procedure and local rules allow.

  7. Printed Service Records

    Print maintenance data and operation records for the job file.

How to Use

  1. Identify refrigerant and requirementsConfirm R134a or HFO-1234yf, the exact charge, PAG/POE oil and any hybrid/EV procedure from reliable sources.
  2. Select the matching circuitUse only the dedicated refrigerant path, tank and couplers for the confirmed gas.
  3. Inspect and enter the jobCheck tank protection, hoses, scales, oil and power; enter values from the database or manually and verify each one.
  4. Recover, evacuate and holdFollow the touchscreen prompts and stop for any failed check or contamination concern.
  5. Add oil and chargeUse only an approved charge path and measured refrigerant and oil amounts.
  6. Print, verify and disconnectReview pressures and cooling performance, print the record and disconnect safely.

Good to Know

Caution
  • Never cross-connect refrigerants; use only the circuit that matches the identified vehicle refrigerant.
  • Do not disable overfill protection. Overfilling the tank may cause an explosion; keep it on its load platform and use only manufacturer-approved tanks.
  • Liquid refrigerant can cause frostbite and eye injury; wear safety glasses and gloves and ventilate the area.
  • For hybrid and EV work, follow the exact OEM oil chemistry and high-voltage procedure.
  • Use grounded power matching the regional nameplate, and disconnect power before disassembly or maintenance.
Care
  • After replacing the filter-drier, reset it on the device page; if no prompt appears, the manual’s reset password is 8609.
  • A failed hold check calls for connection checks and an approved leak-location method.
  • Do not store gasoline or other flammable substances near the equipment.

Efficient and Reliable Freon Recovery Machine!

The AUTOOL LM708 is an excellent refrigerant recovery machine for automotive AC systems. It’s fast, efficient, and easy to operate. I’ve used it for several R134a and R1234yf systems, and it performs flawlessly every time. The automatic recovery, recycling, and refilling functions save me a lot of time in the workshop. Compared to other brands I’ve used, the LM708 is more user-friendly and has a much better price-to-performance ratio. Definitely a great investment for any auto repair shop!

I’ve worked with several refrigerant recovery machines over time. The AUTOOL LM708 stands out as one of the most reliable and efficient models I’ve used. What really sets the LM708 apart is its fully automated recovery process. You can pre-set the parameters, and the machine handles the recovery, recycling, and refilling of refrigerant with almost no manual intervention. This is a huge time-saver, especially during peak service seasons. The refrigerant purification system is highly effective — it recovers refrigerant directly from the vehicle’s AC system and transfers it into your storage tank, free from contaminants. For any shop looking to reduce waste and boost efficiency, that’s a big win. Build quality is solid, the user interface is intuitive, and the performance is consistently accurate. Whether you’re working with R134a or 1234yf, the LM708 handles both with ease. If you’re serious about upgrading your workshop with a cost-effective, automated, and reliable AC recovery machine, the AUTOOL LM708 is absolutely worth considering.

The AUTOOL LM-708 works perfectly for detecting refrigerant leaks!

The AUTOOL LM-708 works perfectly for detecting refrigerant leaks! It’s highly sensitive and quickly pinpoints even small leaks. The adjustable sensitivity levels and audible alarm make it super easy to use. I also love the rechargeable battery, which is very convenient. The build quality is solid, and the LED light helps in low-light areas. This tool is a must-have for AC system diagnostics.

very convenient

I used to have to run to the repair store when my air conditioner wasn’t cool, but this time I bought the AUTOOL LM708 and it just opened the door to a new world! This machine can recover and purify the refrigerant, and save a lot of money by recovering the refrigerant in the air conditioning system. I like its automation function, after setting the parameters, you do not have to worry about, the machine itself will be recycled, purified all done, really save time and effort.
