I do a thorough inspection and fix any problems twice a year. Also do a look around before and after every use. Better and cheaper to fix things before they break or damaged to the point they have to be replaced. There are enough things that can be damaged or break during normal operations without tempting fate.Wow, very thorough. Want to do mine next?
Spent my time on the ground 100' or more from the garage in a snow storm trying to fix something that I could have prevented.
