Abstract
A pneumatic power tool includes a pneumatic motor mounted in a housing and supplied to pressured air through an air control unit to rotate a drive coupler, a coupling shell member surrounding the drive coupler and having axially opposite actuating and engaging regions, an output spindle having a bearing surface disposed between the drive coupler and the engaging region, and an override clutch unit coupling the drive coupler to the coupling shell member. An override movement of a driven clutch half on the engaging region brings the actuating region to move axially so as to force a latch to an unlatched position such that the air control unit is displaced to a shut-off state.
