The TUXING TXESB041-2 is a gasoline-powered, high-pressure air compressor designed for applications requiring a pure, high-pressure gas source, such as diving and paintball. It features an automatic stop function for user convenience and safety.
2. Safety Information
WARNING: Failure to follow these safety instructions could result in serious injury or death.
- Always operate the compressor in a well-ventilated area to prevent carbon monoxide poisoning from engine exhaust.
- Ensure all connections are secure before operation to prevent high-pressure leaks.
- Do not exceed the maximum rated pressure of 30 MPa (4500 Psi). The auto-stop feature is a safety mechanism, but manual monitoring is always recommended.
- Wear appropriate personal protective equipment (PPE), including eye and ear protection, during operation.
- Keep children and unauthorized personnel away from the compressor during operation.
- Do not touch hot surfaces, such as the engine or compressor head, during or immediately after operation.
- Use only recommended lubricants (food-grade quality) as specified in the maintenance section.
- Regularly inspect the compressor for any signs of damage, wear, or leaks. Do not operate a damaged unit.
- Refer to the gasoline engine's separate manual for specific safety instructions related to fuel handling and engine operation.

5. Setup
Before first use, ensure the compressor is placed on a stable, level surface in a well-ventilated area, away from flammable materials.
- Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage.
- Fueling the Engine: Fill the gasoline tank with appropriate fuel as specified in the engine's manual. Do not overfill.
- Adding Compressor Oil: Ensure the compressor oil reservoir is filled to the correct level with special high-pressure compressor oil (food-grade recommended). Refer to the oil level indicator.
- Connecting Hoses: Connect the high-pressure hose to the compressor's output port and to the tank or device you intend to fill. Ensure all connections are tight and secure.
- Check Filters: Verify that the intake filter and oil filter are correctly installed and clean.

6. Operating Instructions
Follow these steps for safe and effective operation of your TUXING high-pressure compressor.
- Preparation:
- Ensure the compressor is on a stable, level surface.
- Confirm adequate ventilation.
- Check fuel and oil levels.
- Verify all hose connections are secure.
- Open the bleed valve on the compressor to release any residual pressure before starting.
- Setting Pressure: Adjust the pressure switch to your desired shut-off pressure (maximum 30 MPa).
- Starting the Engine: Follow the starting procedure for the gasoline engine (typically involves choke, throttle, and pull start or electric start if equipped). Refer to the engine's specific manual if needed.
- Compressing Air: Once the engine is running smoothly, close the bleed valve. The compressor will begin to fill the connected tank. Monitor the pressure gauge.
- Automatic Shut-off: The compressor will automatically stop when the preset pressure is reached.
- After Compression:
- Turn off the engine.
- Slowly open the bleed valve to release pressure from the compressor system.
- Disconnect the high-pressure hose from your tank.

7. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your compressor.
- Oil Change: Change the compressor oil after the first 20 hours of operation, then every 50-100 hours or as recommended by the oil manufacturer. Use only special high-pressure compressor oil (food-grade recommended). The oil capacity is 0.3L.
- Filter Replacement:
- Intake Filter: Inspect and clean the intake filter regularly. Replace if damaged or excessively dirty.
- Oil Filter & Separator: Replace these filters as per the manufacturer's recommendations or if air quality degrades.
- Bleed Valve Usage: Always open the bleed valve after each use to release moisture and prevent corrosion in the system.
- Belt Inspection: Check the drive belt for wear and proper tension periodically. Adjust or replace as necessary.
- General Cleaning: Keep the exterior of the compressor clean and free of debris to ensure proper cooling.
- Storage: When storing for extended periods, drain fuel from the engine and ensure the compressor system is depressurized and dry.
