Key Features
Integrated R134a Recovery, Evacuation, and Recharge
R134a-Only Service
LM707 is an R134a refrigerant recovery machine that combines recovery, evacuation, and refilling for vehicles that use confirmed R134a.
Automatic Recovery, Vacuum And Recharge
Preset the job parameters, then run recovery, evacuation and refilling in sequence. Monitor the prompts and check final results through the service process.
Refrigerant Recovery and Charging Scale
Measure refrigerant weight during recovery and refilling with the built-in electronic scale, which has a stated accuracy of ±10 g.
Recovered-Refrigerant Cleaning
A built-in filter and separator clean recovered R134a for permitted reuse; contamination and local-rule checks remain external.
Separate Oil Handling
Two 350 mL bottles separate new oil from used oil for compressor-oil draining and refilling according to the service procedure.
Onboard Working Tank
Keeps R134a available for repeat compatible service; confirm the exact tank rating for the selected machine.
Six-Language Interface
The interface supports English, German, Spanish, Portuguese, Arabic, and Chinese for easier operation in different workshops.
Centralized Controls
5-inch display, keypad and dedicated pressure gauges keep setup and system readings together.
Scheduled Ownership Tasks
Plan filter replacement after 100 kg of recovered refrigerant, vacuum-pump oil service at 600 minutes or earlier if contaminated, and circulation purification about monthly.
Filter Reset Support
After filter replacement, use reset password 8609 only when the prescribed prompt is absent and the current manual directs that step.
12kg Internal Tank
The refrigerant tank can store up to 12kg of R134a and can continuously replace refrigerant for multiple vehicles.
Rated Power
The LM707 is rated at 800 W.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safety & Compatibility
Confirm R134a, Vehicle Procedure, Oil, and Service Ports
R134a Only
Never connect LM707 to HFO-1234yf, mixed, unidentified or another refrigerant.
Keep Tank Protection Active
Never fill the working tank above 80% of its effective capacity. Confirm the installed tank rating before calculating the limit.
Maintain At Least 3 kg For Recharge
Recharge may not operate when onboard refrigerant falls below 3 kg.
Limit Recovery Starts
Do not start refrigerant recovery more than 10 times per hour.
Never Use Compressed Air
Do not use compressed air to pressure/leak-test the station or vehicle A/C circuit.
Confirm Regional Power
Use grounded power matching the exact unit nameplate; do not rely on blanket 110/220 V comparison text.
Read Instructions First
Read the instruction manual carefully before using the equipment.
Avoid Flames and Heat
Do not use the equipment near open flames or hot objects.
Keep Refrigerants Separate
Do not mix R134a with other refrigerants.
Verify Refrigerant and Stop Engine
Before operation, check the refrigerant type used in the vehicle A/C system and turn off the car engine.
Internal Tank Fill Limit
The internal tank’s actual usage capacity should be 80% of its maximum capacity, which is 12kg.
80% Tank Limit Rationale
This limit helps avoid severe accidents caused by additional pressure from external factors.
Maintain 3kg Minimum
To ensure optimal recharging, the internal tank should not contain less than 3kg refrigerant.
Below 3kg May Block Charging
If refrigerant is below 3kg, recharging may not be possible.
Keep Valve Settings Unchanged
Do not modify the pressure-reducing valve or system settings.
Limit Compressor Starts
Excessive start frequency may damage the compressor.
Normal Oil Discharge Bubbles
Refrigerant oil generally bubbles when the car compressor discharges it.
Match Oil Refill Amount
The amount of oil to add depends on the discharged amount; avoid overfilling.
Maintain Vacuum Pump Oil
During daily maintenance, add vacuum pump oil to the normal level inside the equipment.
Replace Filter After 100kg
Replace the filter after 100kg use.
Run Monthly Cycle Purification
Run cycle purification about once a month.
Test Results
Verify Each R134a Recovery, Evacuation, and Recharge Stage
Read the Scale Specification
The ±10 g value is the scale specification. Follow the complete service procedure when verifying recovered and charged amounts.
Vacuum Result
Compare the achieved/held vacuum with the vehicle procedure; the station does not locate leaks.
Oil Replacement
Base new-oil quantity and chemistry on removed oil and vehicle/OEM requirements, not a generic vehicle type.
Post-Service Performance
Check pressures and cooling operation; abnormal results require separate electrical, airflow, mechanical or leak diagnosis.

FAQs
R134a Station Setup and Service Questions
What Refrigerant Does LM707 Support?
R134a only. Do not mix it with other refrigerants, and verify the vehicle A/C refrigerant before operation.
Does it identify refrigerant?
No. Identify and isolate unknown or contaminated refrigerant before connection.
What does the automatic mode do?
After setup, it runs configured recovery, evacuation and recharge steps; the technician still verifies inputs, connections and results.
What tank capacity applies?
Confirm the installed tank rating for the selected version and never exceed 80% of its effective capacity.
Why Should The Tank Keep At Least 3kg Refrigerant?
Keep at least 3 kg of refrigerant in the internal tank because recharging may not be possible below that level.
When is the filter replaced?
The service reminder is based on 100 kg of recovered refrigerant. Follow the current manual for replacement and reset.
What Is The Filter Reset Password?
After replacing the filter on the new LM707, reset it on the device page. If no prompt appears, enter the universal password “8609” to complete the operation.
- Use it after filter replacement only if the new LM707 does not display the prescribed reset prompt, following the current manual.
When should pump oil be serviced?
The reminder is set at 600 minutes; replace the oil sooner if it becomes turbid or contaminated.
Can I Use Compressed Air For Pressure Or Leak Testing?
No. Do not use compressed air for pressure or leak testing on either the LM707 machine or the vehicle A/C circuit.
How is LM707 different from LM708?
LM707 is the core R134a station. LM708 adds independent R134a/HFO-1234yf systems, touchscreen, five scales, database and printing.
Can LM707 Work With HFO-1234yf?
No. LM707 charges and recovers only R134a refrigerant. If HFO-1234yf support is required, choose LM708.
How Much Refrigerant Can The Internal Tank Use Safely?
The internal tank’s actual usage capacity should be 80% of its maximum capacity, which is 12kg. This helps avoid severe accidents caused by additional pressure from external factors.
How Often Should I Replace The Filter?
Replace the filter after 100kg of use, following the device prompt. Contact AUTOOL Store support if you need the filter replacement code or replacement-filter support.
How Often Should Vacuum Pump Oil Be Maintained?
After the vacuum pump has been used for a total of 600 minutes, the equipment prompts you to reset the vacuum pump oil data. If the vacuum pump oil contains impurities or becomes turbid, replace it promptly.
How Many Times Can I Start Recovery Per Hour?
Start the automotive refrigerant recovery procedure no more than 10 times per hour. Starting recovery too frequently may damage the compressor.
What Is The Difference Between LM707 And LM708?
LM707 supports R134a only and uses a 5-inch display. LM708 supports R134a and HFO-1234yf, has a 7-inch touch screen, 5 electronic scales, data printing, a built-in database, operation record inquiry, system automatic leak detection, and HP / LP / HP+LP filling method selection.
