3. Safety Instructions
Always follow basic safety precautions when using this air compressor to reduce the risk of fire, electric shock, and personal injury.
- Electrical Safety: Ensure the power source is 110V/60Hz. Do not operate the compressor with a damaged cord or plug.
- Pressure Safety: Never exceed the maximum operating pressure of 115 PSI. The compressor is equipped with automatic pressure relief protection.
- Overheating Protection: The unit has two large cooling fans and automatic overheating protection. If the motor overheats, it will shut off automatically. Allow it to cool before restarting.
- Tank Integrity: The tank is constructed with Q235B structural steel and multiple protective layers to resist explosions and leakages. Do not modify or weld on the air tank.
- Operating Environment: Use the compressor in a well-ventilated area. Keep children and bystanders away during operation.
- Personal Protective Equipment: Always wear safety glasses or goggles when operating the air compressor or using air tools.
4. Setup
- Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage.
- Wheel Assembly: Attach the wheels to the compressor base using the provided hardware. Ensure they are securely fastened for stability and portability.
- Handle Attachment: Secure the handle to the compressor frame.
- Initial Check: Before first use, ensure all connections are tight and the drain valve at the bottom of the tank is closed.
- Power Connection: Connect the compressor to a grounded 110V/60Hz electrical outlet.
5. Operating Instructions
- Starting the Compressor: Turn the power switch to the "ON" position. The compressor will begin to fill the tank.
- Fast Inflation System: The compressor features a double tube and double cylinder intake system for efficient filling. It can fill the empty tank to maximum pressure (115 PSI) in approximately 60 seconds.

- Pressure Adjustment: Use the pressure regulator knob to set the desired output pressure for your air tools. Monitor the regulated pressure gauge.
- Connecting Air Tools: Attach your air tool to one of the quick couplers. Ensure a secure connection.
- Automatic Operation: The compressor will automatically shut off when the tank reaches its maximum pressure (115 PSI). When the internal pressure drops below 70 PSI during use, the motor will restart automatically for approximately 30 seconds to maintain continuous air supply.
- Quiet Operation: This compressor operates at a maximum noise level of 70dB, comparable to a normal conversation, thanks to its high-quality silencers and filter cotton.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air compressor.
- Drain Tank Daily: Open the drain valve at the bottom of the tank after each use to release any accumulated moisture. This prevents rust and extends tank life.
- Air Filter Inspection: Periodically inspect the air filters for dirt and debris. Clean or replace them as needed to ensure efficient air intake.
- General Cleaning: Keep the compressor clean and free of dust and debris. Use a dry cloth to wipe down surfaces.
- Oil-Free Design: This compressor features an oil-free motor, eliminating the need for oil changes or lubrication.
7. Troubleshooting
Refer to the following common issues and solutions before contacting customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not start. | No power, power switch off, or thermal overload. | Check power connection. Ensure switch is ON. If motor is hot, allow to cool down; automatic overheating protection may have activated. |
| Compressor runs continuously or frequently. | Air leak in system, excessive air consumption, or pressure switch malfunction. | Check all connections for leaks. Ensure air tools are not consuming more air than the compressor can supply. If issue persists, contact support. |
| Low air pressure at outlet. | Regulator set too low, air leak, or clogged air filter. | Adjust the pressure regulator. Check for leaks. Inspect and clean/replace air filter. |
| Excessive noise or vibration. | Loose components, worn parts, or unit not on a level surface. | Check for and tighten any loose bolts or screws. Ensure the compressor is on a stable, level surface. |
