Abstract
There is disclosed a sawing machine including a workbench, a band saw pivotally installed on the workbench, a weight movable between an idle position on the workbench and an operative 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 in order to lower the band saw toward the workbench.
