We report on the tuning of the ultra-slow muon beam line at J-PARC MUSE using Li impurities in a tungsten muonium production target in place of positive muons. Li ions were evaporated from the tungsten target by heating it up to 2000K and were transported in the ultra-slow muon beam line. The Li ion beam was monitored by micro channel plates installed at several points in the beam line. The Li beam was successfully transported to the end of the beam line after optimization of beam line parameters.
