Details of how to use and care for the rototiller/edger
My husband purchased a Stihl 55 tiller for me, and I have no idea how to run it..the store told me they would send me a manual, but after several visits and inquiries about it, I still have not received one. I no longer count on them and my husband is away for work, often. I just want to know how to start it..I can handle it from there. Thank you! i am not mechanically inclined..I need help that I can print and keep.
