Patent ID: 6966255

Claim:
A lock-out assembly for a strapping tool for tensioning a strap around a load, adhering the strap onto itself, the strapping tool having a body, a tensioning wheel and a drive for the tensioning wheel, a sealer and a drive for the sealer and a pneumatic module including a tensioning valve and a sealer valve disposed adjacent one another in the module, each of the valves being reciprocal between an actuated position and a non-actuated position and each operably associated with a lever for reciprocating the respective valve between the actuated and non-actuated positions, the levers being pivotable about a pivot for contacting and reciprocating their respective valves, the levers being pivotable independent of one another, the lock-out comprising: an arm operably mounted to the pneumatic module, the arm having a first engaging portion for engaging the tensioning valve lever and a second blocking portion for blocking the sealer valve lever, wherein the arm is movable between a first position in which the tensioning valve lever is in the non-actuated position and the arm block portion interferes with movement of the sealer valve lever to prevent moving the sealer valve to the actuated position, and a second position wherein the tensioning valve lever engages the arm engaging portion to move the arm blocking portion from interfering with the sealer valve lever to permit moving the sealer valve lever into contact with the sealer valve to move the sealer valve to the actuated position.
