I bought a NOMA Snow Thrower (627104X8A) from a neighbor who moved to a warm climate, but the manual was missing. I believe that NOMA is/was made by Murray. My interest is in making adjustments to the belts, for example. Is there a manual available? For example, does the manual for Murray 629108x84B, or some other one available at this site, correspond to the manual needed by me? Thanks
