Aermotor Windmill Maintenance

An Aermotor Windmill that is correctly assembled and installed is virtually maintenance free!


Every Six Months Maintenance:

  • Check to make sure the windmill is running correctly. This is just a visual check from the ground or your vehicle.

Once A Year Maintenance:

  • Under normal conditions, the mill requires a change of oil once a year. You should use SAE 10 or less. The oil should be of the non-detergent type. Click HERE to order windmill oil.
  • Check to see if nuts and bolts have remained tight on the mill and tower. Do this at the same time you change the oil, or after a major storm.
