FIELD: process engineering.
SUBSTANCE: invention relates to hand-held electrically driven machine. Machine casing accommodates drive assy articulated with working tool. Said casing comprises two separate parts with primary damping element arranged there between. Besides, hand-held machine comprises safety part jointing casing two parts together and secondary damping element acting between said two parts in parallel with said primary damping element. At normal operation of the primary damping element secondary damping element is not in fact fully loaded. At excess deformation of primary damping element and change in relative arrangement of the casing parts vibrations are killed by secondary damping element. Aforesaid safety part represents a rope while secondary damping element is composed of a tube fitted on said rope.
EFFECT: decreased vibrations.
