Service Tips

Before performing any work or service, de-energize (turn off) and disconnect, lockout and tag, or block off all mechanical, electrical, hydraulic and pneumatic equipment that presents a danger, particularly grain-moving equipment. Grain should not be emptied or moved into or out of the bin while workers are inside.


  • ​Mow and remove all weeds and debris for safety and to remove safe harbors for vermin.
  • Using proper respiratory protection, sweep and clean the interior of the bin. Pay special attention to cracks and any areas, such as inside stiffeners and obstructions, that may contain insects or mold-harboring debris.
  • Following all instructions and using proper respiratory and safety equipment, Spray and treat the exterior and the interior of the bin, including under a full or partial floor, to minimize insect infestations and mold. Every few years check for accumulations under the floor and clean there, even if that means taking up the floor.
  • Using proper respiratory protection, inspect and clean all passive or powered roof vents to ensure free flow of aeration or ventilation air.
  • Inspect for leaks, rusting, or other deterioration of the structure of the bin to make sure it is structurally correct and repair any issues found.
  • Check the condition of the bottom ring seal and repair if necessary to keep water from entering the bottom of the bin.
  • Check the condition of the aeration fan, transition, and entrance color for damage and proper seal.
  • If your system includes a drying bin, carefully check the gas supply lines, burner, vaporizer and burner gas train for leaks and make sure all are clean and free of debris, particularly the burner gun or exit. Have a qualified service technician repair any problems found. Make sure any rubber hoses are in good condition and replace them every 10 years or according to local gas ordinances.
  • Inspect the entrance door making sure it is mechanically sound and shuts and seals tightly. Make sure these doors are correctly closed before you start to load the bin.


  • When loading the bin, practice multiple coring to promote proper aeration of all the grain.
  • Do not overfill the grain; this can put stress on the structure and may prevent proper ventilation through the roof vents.
  • As soon as possible, pull the center of the bin down to the same depth as at the wall to promote center aeration.
  • If leaving the grain cold, make sure the aeration fans and discharge augers are bagged off to prevent warm wet air from entering the bin. Do not keep cold grain past June 1st.
  • Always practice proper safety with respiratory equipment as well as fall protection when working around any grain bin.
