    Thermostat abnormality

    The temperature measurement line is not connected or connected improperly; the temperature setting is improper

    Connect the temperature measurement line correctly: Adjust the set temperature within the normal function range.


    Hydraulic station motor abnormal

    Thermal relay action

    Reset the thermal relay and check the motor coil


    Vibrator does not move

    Compressed air pressure is low; jammed by garbage

    Check the compressed air pressure and remove the vibrator if it is correct.


    Injecting sand with the indenter and the barrel

    Indenter seal rubber ring is damaged

    Replace the rubber ring.


    When the gun is lifted, the shot is sprayed with sand.
