Hello, I am a first time owner of any type of mower (Mini FasTrak) and I have a couple of questions. 1. How and when to I clean my Mini FasTrak? 2. It seems as if I am using the right bar more than the let to move and speed up, Is this Normal? 3. When do I change the oil? 4. Can It be stored outside? 5. Can any key start them, because I don't have a storge unit?
