Dierential operators Δ+q\Delta + q are considered on metric Cayley graphs of the nitely generated free groups FM\mathbb F_M. The function qq and the graph edge lengths may vary with the MM edge types. Using novel methods, a set of MM multipliers μm(λ)\mu_m(\lambda) depending on the spectral parameter is found. These multipliers are used to construct the resolvent and characterize the spectrum.
