4. Setup
Before operating your compressor, follow these setup steps:
4.1 Initial Preparation
- Check Oil Level: Upon receiving the air compressor, check the oil level using the dipstick. The oil level should be in the middle of the two grids on the dipstick. After inspection, securely tighten the refueling port.
- Initial Run (No Load): When using the compressor for the first time, it is crucial to perform an initial run without load. Open both the first stage drain valve and the two-stage release/drain valve. Connect the power supply and turn on the power switch. Allow the compressor to run for two minutes without load to ensure proper lubrication and system function. After this initial run, turn off the power supply.
4.2 Connecting to a Gas Cylinder
Refer to the following visual guide for connecting the compressor to a gas cylinder:
- Connect the appropriate adapter (e.g., G5/8 connector or diving connector) to the gas cylinder.
- Attach the compressor's high-pressure hose to the adapter on the gas cylinder. Ensure all connections are hand-tight and secure.

5. Operating Instructions
Once the compressor is set up and connected, follow these steps for operation:
- Close Drain Valves: Ensure both the first stage drain valve and the two-stage release/drain valve are fully tightened.
- Open Gas Cylinder Valve: Slowly open the valve on the gas cylinder you intend to fill.
- Start Compressor: Turn on the power switch of the compressor.
- Monitor Pressure: Continuously monitor the pressure gauge on the compressor. The maximum pressure can reach 4500Psi (300Bar/30Mpa).
- Automatic Shut-off (if applicable): For models with automatic shut-off, the compressor will stop once the set pressure is reached. For manual models, turn off the power switch once the desired pressure is achieved.
- End of Inflation: After filling, turn off the compressor power switch. Tighten the valve of the gas cylinder. Open the first stage drain valve and the two-stage release valve to release residual pressure from the compressor system before disconnecting the hose.
5.1 Filling Performance
The TUXING compressor offers efficient filling times:
- A 6.8L gas cylinder can be filled to 300Bar in approximately 21 minutes.
- A 12L gas cylinder can be filled to 200Bar in approximately 25 minutes.
6. Maintenance
Regular maintenance is crucial for the longevity and performance of your compressor.
6.1 Lubrication
- Use only special high-pressure compressor oil, specifically ISO grade 100/150.
- Check the oil level before each use. The oil tank capacity is 300cc (0.3L).
6.2 Air Filtration
The compressor features a 3+1 layer filtration system with triple filter materials (molecular sieve and activated carbon) to ensure clean and fresh breathing air.
- Regularly inspect and replace the filter elements to maintain optimal air quality. This is especially important for applications requiring breathing air, as per EU EN12021 and GB18435-2001 standards.
- The advanced air purifier ensures impurities are removed.
6.3 Drain Valves
The compressor is equipped with double drain valves for convenient operation.
- After each use, open the drain valves to release any accumulated moisture and pressure. This helps prevent corrosion and maintains system integrity.
6.4 Safety Valve
The upgraded safety valve allows for adjustable pressure settings and automatic purging.
- The new version of the safety valve can be set to automatically purge between 100Bar and 400Bar when the pressure is reached, eliminating the need to replace components during maintenance.
6.5 Cooling System
The compressor features a four-cylinder fan cooling system for strong and fast heat dissipation.
- Ensure the cooling fans are free from obstructions to maintain efficient heat dissipation.
7. Troubleshooting
