VII. Performance Specifications

  •  Centrifugal Clutch allows the operator to stop the vibration simply by  
    adjusting the throttle lever to the SLOW position. This prolongs vibrator  
    head bearing life by preventing excess heat build up when the head is not  
    submersed in the concrete.
  •  Throttle Control allows the operator to obtain the best speed of vibrator for  
    the size of head and the type of concrete being worked. The unit can be used  
    right hand or left hand as needed.
  •  Standard Quick Disconnect makes it simple to remove or attach the flexible  
    drive without tools.
  •  Engine swivels 180° allowing the flexible drive to more easily push back  
    behind the operator as it is pulled from the concrete. Motor remains “tight”  
    so it does not move excessively as the operator changes positions.
  •  The Engine will operate in any position.
