Product specific safety precautions
This equipment is designed be operated by qualified personnel. It should only be operated after
reading and understanding the safety warnings and operating procedures in this instruction manual.
1. Do not smoke near this equipment.
2. Firework is strictly prohibited during operation, keep away from heat, high voltage, flammable
and explosive place
3. Use in a well ventilated area.
4. When leaks are found in the equipment or hoses, immediately turn the air pressure off and repair
the leaks.
5. Once leakage is found in the hose or other components during operation, turn off air compressor
immediately, conduct a detailed inspection and proceed with troubleshooting.
6. Do not exceed the recommended operating air pressure. This could damage equipment. See
specification on Page 5.
7. Keep a type ABC fire extinguisher nearby in case of fires.

9. Do not start engine during the time of oil extraction. Otherwise it will cause the damage of
extraction probes and injuries of people.
10. Be careful for the oil extracted out from the vehicle, as temperature of oil is high, always between
40~60℃
11. Used oil should be properly disposed or recycled. Please contact with your local waste liquid/solid
authority for information on recycling.

Operation Instruction
1) Vacuum Generation with Cylinder
1. Operating air pressure: 6～8bar/ 87～116PSI.
2. Make sure all valves are close. (FIG.1)connect air source with air inlet(Part No.32HC-0801) , turn on air
valve for vacuum extraction, When finger reaching to the MAX area on the vacuum gauge, turn off air
inlet valve .
FIG.1
Notice: Under a working condition without air source. Please pump with vacuum air before use.
2) Extraction
1. Ensure the oil tank is under negative pressure, FIG.2 remove engine oil case., choose suitable probe
(which is the largest diameter one can be inserted into the engine) and tightly connect it to the extraction
pipe connector. Insert the end of the probe into the engine oil inlet hole, FIG.4 Turn on the ball
valve(Part No.32HC-1703) for oil extraction.

６
NOTICE:
Do not exceed maximum oil extraction temperature 60℃.
Hold the hose protection sheath during extraction to avoid scald
Place the machine in a flat ground to avoid sliding under working condition
Oil temperature higher than 80 ℃will cause seriously damage to the components, in worst case it
could lead to machine failure.
3) Oil Ejection
Oil ejection from cylinder to oil tank
1. When the oil level reached cylinder ‘STOP’ warning line, please empty
the cylinder with oil ejection.
2. Turn on ball extraction valve(Part No.32HC-1005) ，at the same time
turn on mini ball valve(Part No.32HC-0803) from the hose to release
cylinder pressure and oil drain into the oil tank.
3. Turn off oil extraction valve(Part No.32HC-1005) and hose ball
valve(Part No.32HC-1703) after completion of oil ejection.
4) Oil Collection
1.Lift the vehicle to proper height
2.Move the oil extractor below the car engine, oil tray position right
under the vehicle oil drain hole.

FIG.2 FIG.3 FIG.4

７
3. Release plum knob to adjust lifting pole . tighten plum knob to fix its height, open wing valve(Part No.
21HC-2106), release oil drain bolt for oil collection from vehicle.
5) Tank Emptying
When the oil retained in tank near full(see oil window), You need to eject oil out into a disposal tank and
resolve the waste oil accordingly to the instruction of local government.
1. Turn off all the valves.
2. Hold the ejection hook and insert it into the external disposal tank.
3. Connect the air compressor with the air inlet(Part No.32HC-0801)
4. Turn on the wing valve(Part No.32HC-0402) gradually, addingtank
pressure, turn off air compressor when pressure reach to desired pressure.
(The valve will automatically release pressure when the tank pressure reach
1.0 bar/14PSI, turn off the air compressor immediately and quickly
drop the tank pressure below 0.7bar/10PSI,otherwise it could lead
to serious incident)
FIG.7
As FIG.10 shows, discharge Residual oil from Residual oil cup when it reach STOP sign.
