Fault: Air Leak
Reason: The one-way valve is defective,
Air leakage from safety valve
safety valve open
loose pipe or hose connection
Measures: When there is pressure in the air storage tank and the compressor stops rotating, the defective check valve will cause continuous air leakage. If the valve leaks, it must be replaced;
Manually pull up the relief valve poppet and replace if the valve is still leaking
If the pressure switch is normal, the safety valve is defective and must be replaced
Tighten the leaking connections and check with soapy water under pressure. (don't be too tight)
Fault: Motor does not run
Reason: The pressure switch button is in the 0FF position
Starter overload protection switch tripped
Blown fuse or tripped circuit breaker
Wiring error
Air pressure exceeds
Opening pressure of the pressure switch
loose electrical connection
Motor failure
Action: Put the button in the ON position
Let the starter cool and press the reset button
Check for blown fuses. Replace or reset circuit breakers as needed. Do not use fuses or circuit breakers higher than the Tin Fan standard.
Check if the wiring is correct, refer to the recommended wire type.
When the air tank pressure drops below the starting pressure of the air switch, the air compressor motor automatically starts
Check wiring
Unless there is obvious damage to the motor, remove the motor and send it to the local motor manufacturer's service center for inspection. Replace if necessary
Fault: Exhaust pressure too low
Cause: Airflow is restricted at the air intake
Damaged cylinder head gasket
Broken valve
Damaged or worn piston rings
The v-belt is too loose
Air leak
Excessive use of compressed air
Action: Clean or replace the air intake filter
Replace with new cylinder head gasket
Replace the new valve plate and gasket
Replace with new piston rings
Adjust belt tension if needed
Check and solve according to the phenomenon of air leakage
Reduce compressed air consumption, air compressor capacity is insufficient relative to air demand
