kioti nx4510hst

Hi folks, I am having issues with my NX4510HST range selector. It seems to need adjustment as its not switching at the right locations and I cant seem to reach high and low kicks in were medium should be. Does anyone have details on how to adjust the range selector or if this is a bigger issue...

Just delivered yesterday, my brand new tractor. its my 3rd Kioti and I am happy with the tractor and the dealership. Bromley Farm Supplies in Douglas, Ont. Its all good! Any words of wisdom regarding this tool? Thanks, Bob G
