I have two look a like chainsaws, but I cann't find any manual of them. My Wild cat (Mod nr 60016002)starts well when it is cold but fails on hot start? The seccond one Mac Cat (Mod nr 60016017)has some minor changes but is almost the same. When I look for both Mod nr's I cann't find the operating manual. The only thing I found was a part list and some exploded views.
