A tensioner for strap includes a housing, a battery, a motor, a tension head having a tension wheel operably connected to the motor and a nosepiece having a pinch element. The nosepiece is mounted to the tension head for movement relative thereto. An actuator handle is mounted to the nosepiece to move the pinch element toward and away from the tension wheel. A strap sensor is operably connected to a controller and senses the presence or absence of strap between the tension wheel and the pinch element. A home position switch senses pinch wheel proximity to the tension wheel. The nosepiece is moved away from the tension head to introduce strap to the tool and the home position switch changes state to signal the controller to permit actuation of the motor when the strap sensor senses the presence of strap between the pinch element and the tension wheel. |
