FIELD: machine engineering.
SUBSTANCE: working tool has a working element and an internal combustion engine which drives the working tool, a starting mixture enrichment device for internal combustion engine and a brake mechanism for the working element. The working tool has a mode selector switch to control starting mixture enrichment device. The starting mixture enrichment device in at least one of its positions actuates brake mechanism. The brake mechanism is made in the form of differential band brake. The mode selector switch has two sections which are movable relative to each other. The first section of the mode selector switch affects the differential band brake. The second section of the mode selector switch has a control element affecting an air damper element of the internal combustion engine.
EFFECT: simplification of the tool design.
