What’s the use method and precautions of sucker rod falling-off preventor.

Before going down the well, you must check whether the rotation is flexible or not, whether the pin bolt is loose or not, whether the appearance (especially the thread) is damaged and corroded. If the rotation is not flexible, the pin is loose, and the appearance is damaged and corroded, it should be returned to the assembly unit immediately. Rotating by hand, the direction of forward rotation should not be rotated, and the direction of reverse rotation should be flexible.
