Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your VEVOR air compressor pump head. Ensure all components are securely fastened and aligned.
Key Installation Steps:
- Mounting the Pump Head: When placing the pump head, ensure the motor pulley and the belt pulley are in the same straight line. Precise alignment minimizes vibration and prevents bearing displacement.
- Securing the Belt: Tighten the screws to ensure the belt is properly tensioned. An incorrectly tensioned belt can lead to inefficient operation or premature wear.
- Lubrication: Before initial operation, fill the pump with appropriate oil. The oil level should exceed the red line of the oil observation mirror by 1-2 mm. Regularly check the oil level during use.
- Connecting Air Lines: Connect the intake and exhaust lines securely. Ensure no leaks are present after connection.

Operating Instructions
Once installed, the pump head is ready for operation. Always ensure the motor (not included) is compatible and correctly connected to the pump head.
General Operation:
- Initial Start-up: After ensuring proper oil levels and connections, power on the motor. The pump head will begin to compress air, building pressure in the connected air tank.
- Monitoring Pressure: Observe the pressure gauge on your air compressor system to ensure the pressure builds steadily and does not exceed the maximum operating pressure of 185 PSI.
- Application Use: The compressed air can then be used for various applications such as inflating tires, powering spray guns for painting, or operating pneumatic tools for woodworking and other tasks.
- Heat Dissipation: The pump head features efficient heat dissipation fins. During operation, high temperatures will be generated. Exercise caution and avoid direct contact with hot surfaces to prevent burns.
