mine has that emergency thing ,i can hear a little motor turning but nothing happens ,i should probly see whats going on with that,may need it someday ,its died a couple times on me up in the air ,any little bit of water in the fuel seems to find the carb on the lil wisconsin
There are two ways to get down without the engine running. One is that little pump kicks in and build up system pressure which opens the pressure activated safety valve on the boom lift. The other way is to use a wrench and open the manual bypass on the safety valve. The latter of course requires someone to be on the ground with access to the cylinder itself.
The one I borrowed had the wisconsin v-4 motor in it. It had an electric fuel pump that fed the carb through the engine cam driven pump. Overall it was a good machine that just needed a little TLC, a few new wires and a leaky tire patched. It is one of many Wisconsin motors I've dealt with that would run fine for a time and then just die, but you could restart a short time later. I've heard it is vapor lock of some sort in the carb and intake that can be fixed, but I don't know the secret for that fix and have always just replaced the whole motor with a new Briggs or Perkins diesel. Life is too short to fight your money making tools. (Yeah right) Lol
