A pneumatically or electrically powered power tool having a rotating working implement carrying output spindle (14), an exhaust or cooling air outlet passage (21), air outlet openings communicating the outlet air to the atmosphere and comprising a first section (22) located on one side of the tool housing (10, 20) and a second section (23) located on an other side of the housing (10, 20), and an air outlet flow directing valve (25) shiftable between a first condition in which it directs the air flow out through the first opening section (22) and a second condition in which it directs the air flow out through the second opening section (23). The air outlet flow directing valve (25) is shiftable by a maneouver mechanism (35, 36) including a rotatable annular handle (35) on the outside of the housing (10, 20) between the first and second conditions in which it alternatively directs the outlet air flow through the first and second outlet opening sections (22, 23). <IMAGE> |
