ABSTRACT:
A hand-held power tool or a hand controlled implement having a primary control system by which a user controls operation of the tool or implement also has a secondary control system of pneumatic form. Operation of both systems must take place before the tool or implement is energized. A tool with primary and secondary handles has an actuator for the primary system on the primary handle and an actuator for the secondary system on the secondary handle. An implement with a single handle has the actuators mounted at different locations on the single handle that are spaced apart by a distance preventing operation thereof by the same hand of a user.
