Improved sawing machine, of the type with blade provided with reciprocating reciprocating movements carried by an oscillating arm, characterized by the fact that the oscillating blade-holder arm is combined with an adjustable device that automatically allows, on the one hand, lift the saw at the end of each active sawing route and keep it up during the return journey, to meet the action of gravity that puts the saw back into active position as soon as each new sawing path is started, and, another part, to moderate, during the active stroke of the saw, the effective cutting pressure, then partially opposing, by means of a hydraulic braking adjustable counterpressure, to that prevailing heaviness.
