    16) Check regularly whether the respiratory valve action is sensitive, especially in the winter should pay attention to the valve of the valve and safety valve at the bottom of the water not to freeze, to prevent the oil out of the operating pressure over the permissible range and drum open , On the breathing valve and safety valve below the fire, but also regular checks to avoid clogging.

    17) irrigation areas are not allowed to wear chemical fiber clothing and nail shoes on the tank, are not allowed to hit the iron in the tank top, also not allowed in the top of the switch flashlight.
