Title: AN ENGINE-DRIVEN TOOL WITH A GENERATOR CONNECTED TO A FAN MOTOR
Abstract:
The present disclosure relates to an engine-driven tool (1) comprising a rotatable work tool (2), an engine (4) that is arranged to propel the rotatable work tool (2), a shielding cover (8) for shielding the rotatable work tool (2), and a dust channel (11) that is formed between the shielding cover (8) and the rotatable work tool (2). A dust hose (14) is arranged to connect the dust channel (11) to a dust container (17) and an electrically driven fan (16) that is arranged to convey air from the dust channel (11) into the dust container (17) via the dust hose (14). The engine-driven tool (1) comprises an electrical generator (18) that is electrically connectable to the fan motor (26) and is arranged to be at least indirectly driven by the engine (4). The electrical generator (18) is furthermore arranged to generate an electrical current when driven, where said electrical current at least indirectly is arranged to propel the fan motor (26).
