2. Safety Information
WARNING: Failure to follow these safety instructions may result in serious injury or property damage.
- Always operate the compressor in a well-ventilated area.
- Ensure the compressor temperature does not exceed 85℃ (185℉). Continuous operation should not exceed 45 minutes. Allow the unit to cool down between cycles.
- Before operation, ensure the breathing rod is installed in place of the oil cap. Add oil to the level of the red dot on the dipstick.
- The maximum filling pressure must not exceed 300 Bar (4500 PSI / 30 MPa). Over-pressurizing can cause explosions.
- Wear appropriate personal protective equipment, including eye protection, during operation.
- Keep children and unauthorized personnel away from the compressor during operation.
- Ensure all connections (filter, hose) are secure and leak-free before starting.
- Do not modify the compressor or its components. Use only original replacement parts.
- Disconnect power before performing any maintenance or cleaning.

4. Setup
Follow these steps for initial setup before first use:
- Unpacking and Inspection: Carefully remove the compressor and all accessories from the packaging. Inspect for any visible damage.
- Oil Preparation: The compressor is shipped without silicone oil due to transportation restrictions. You must prepare and add silicone oil yourself. Locate the oil cap and replace it with the provided breathing rod. Fill the oil reservoir with appropriate compressor oil until the level reaches the red dot on the dipstick.
- Cooling System Connection: Connect the water pump to the compressor using the provided water hoses. Ensure the water pump is submerged in a container of water (e.g., a bucket) during operation to facilitate water cooling.
- Air Filter and Filling Hose: Connect the external oil-water separator filter to the compressor's output. Then, connect the filling hose to the filter. Ensure all connections are tight and secure to prevent air leakage.
- Power Connection: Connect the 110V power cord to the compressor and then to a suitable power outlet.

5. Operating Instructions
Before operating, ensure all setup steps are completed and safety precautions are understood.
- Connect to Tank: Connect the filling hose's 8mm quick connector to the tank you intend to fill (PCP air rifle, paintball tank, or scuba tank). Ensure a secure connection.
- Open Tank Valve: Slowly open the valve on the tank to be filled.
- Start Compressor: Turn on the power switch on the compressor. The compressor will begin to operate.
- Monitor Pressure and Temperature: Continuously monitor the pressure gauge and the temperature gauge. Do not exceed the maximum rated pressure of 4500 PSI (300 Bar) for the compressor or the tank being filled. Keep the compressor's internal temperature below 85℃.
- Stop Compressor: Once the desired pressure is reached, turn off the power switch on the compressor.
- Bleed Air: Slowly open the manual bleed knob to release the pressure from the filling hose. This is crucial before disconnecting the tank.
- Disconnect Tank: Once pressure is fully bled, close the tank valve and disconnect the filling hose from the tank.
Note on Filling Speed: The 1.8KW high-power copper motor allows for efficient filling. For example, a 0.5L diving tank can be filled from 0 to 30Mpa (4500 PSI) in approximately 3 minutes.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your compressor.
- Oil Level Check: Regularly check the oil level using the dipstick. Ensure it remains at the red dot. Refill with appropriate silicone compressor oil as needed.
- Filter Replacement: The external oil-water separator filter elements should be replaced periodically, depending on usage and air quality. Dirty filters can reduce performance and air quality.
- Cooling Water: Ensure the water used for cooling is clean. Replace the water in the cooling bucket regularly to maintain cooling efficiency.
- Cleaning: Keep the compressor unit clean and free from dust and debris. Ensure cooling vents are unobstructed.
- Storage: When not in use, store the compressor in a dry, clean environment, protected from extreme temperatures.
