looking for Clark/Bobcat 310 service manual

[minitank]

I just bought a Bobcat 310 and need to sort it out. I've never owned a machine like this and would like to find a service manual. Does anyone know of site where a copy is posted? Someone had repowered it with a little diesel engine and I'm not seeing any id as to who made it. Seems to run alright but only one speed (no electric clutch on shaft) and with not a whole lot of umph. I'm hoping this will beet using a shovel.
