  John ManningAug 30, 2025
  If 'OVER' frequently occurs, it may be due to an improper upper limit of torque. Try setting the upper limit of torque again. Alternatively, the tightening capability of the tool may not be suitable; try setting the rotation speed again or replace the tool with one that has a low torque range.

  Darius GibsonSep 1, 2025
  If 'UNDER' frequently occurs, it might be because the lower limit of torque is not properly set; try setting the lower limit of torque again. It could also be that the hand is off the throttle lever during tightening; ensure you pull the throttle lever until the tool automatically stops. Lastly, the tightening capability of the tool may not be appropriate; try setting the rotation speed again or replace it with a tool that has a high torque range.
