Identify the leakage point and replace the air pipe.

Replace the oil - gas separation core.
 
5. Damaged Minimum Pressure Valve
 
Inspect the minimum pressure valve and replace it if necessary.

Check if the drive belt is broken (for old machines).
 
7. External Pressure Higher Than Loading Pressure
 
Check if the air tank pressure is higher than the loading pressure.
