Abstract
A sawing machine includes a workbench, a band saw pivotally installed on the workbench, a weight movable between an idle position on the workbench and a working position on the band saw and an adjustable torque provider for providing an adjustable torque to the band saw. The adjustable torque is set to a maximum when the weight is in the idle position in order to lift the band saw from the workbench. The adjustable torque is set to a minimum when the weight is in the working position in order to lower the band saw toward the workbench.
