ABSTRACT The invention is directed to an override arrangement and handle for a shifting mechanism in portable tools. The portable tool includes a housing and a drive motor mounted in the housing. A case extends from the housing and a transmission is operatively connected to the motor and mounted in the case. A shifting mechanism engages the trans- mission for adjusting the same between at least two modes of operation. The shifting mechanism includes a shaft penetrating the case and rotat- able between two positions corresponding to respective ones of the modes of operation. The improvement includes a handle attached to the shaft that is contoured so as to abut against the case when the handle is ro- tated past one of the two positions thereby preventing the operator of the tool from overriding the one position.
