The invention relates to a device on a handheld cutting or sawing machine with a rotatable cutting or sawing blade; a driving machinery for rotating the blade; means for supplying cooling or flushing water on the blade and/or a workpiece; a rear handle with controls for the driving machinery; a front handle bow with a front part (5) which is the normal gripping part of the handle bow; a right hand side part (6) and a left hand side part; and a water valve (8) for control of the flow of cooling or flushing water, said valve comprising a valve housing (27) with a valve house chamber (33); a valve body (36) which is turnable about an axis of rotation (23) by means of a lever (22); an inlet nipple (15) for the connection of a water hose (16) for incoming water to the valve; and an outlet nipple (17) for the connection of a water hose (10) for outgoing water from the valve; and securing means (35, 43) for mounting the water valve on the handle bow. The characteristic features are that the water valve is mounted on the right hand side part (6) of the handle bow, a side (21) of the valve facing the operator, when the operator in a normal operating position is gripping the front gripping part (5) of the handle bow with his left hand; that the lever (22) is provided on said side facing the operator; and that the valve is mounted so close to said gripping part (5) that the operator can reach and manipulate the lever with any of the fingers of his left hand at the same time as he has a grip on the front gripping part of the handle bow. |
