I had a MiniMac 110 , 44 years ago . mainly used it at ground level on gardens, but occasionally had to go up a tree with it. It was so light you could use it in one hand. BUT I read stuff about chainsaw safety, and used to tie my ladder to the tree, then tie myself to the tree . It used to start easily, do a cut at a time.........
Only had one incident when I was cutting a staghorn up when it bucked and the brake didn't come on, but it stopped 2 inches from my nose.....
cheers
speedy
