ABSTRACT:
A work apparatus such as a blower apparatus (1) or a spray apparatus (31) has a drive motor (5), a blower wheel (11) and a blower tube (12). The blower wheel (11) is driven by the drive motor (5) and moves a flow of air through the blower tube (12). The work apparatus (1, 31) has a back carrier (2) on which the drive motor (5) is mounted. In order to avoid electrostatic charges during operation, the back carrier (2) has an arrangement which establishes an electrically conductive connection between the work apparatus (1, 31) and the operator (18) of the work apparatus (1, 31) during operation thereof.
