Abstract: A handheld work apparatus includes: a housing (2); a motor support unit (10) which is separate from the housing (2) and is connected to the housing (2); a drive motor (3) arranged in the housing (2) for driving a tool (5) that rotates about an axis of rotation (8), wherein the drive motor (3) is attached to the motor support unit (10); a protective hood (51), the protective hood (51) at least partially covering the tool (5) and a stop (110) being provided on the protective hood (51). A mating stop (120) is formed on the motor support unit (10), in particular directly, which is provided for operative connection with the stop (110) of the protective hood (51) in order to restrict the pivoting movement of the protective hood (51) to an end position (131).

Abstract: A handheld work apparatus includes a housing (2). A drive motor (3) is arranged in the housing (2) for driving a tool (2) that rotates about an axis of rotation (8). A protective hood (51) at least partially covers the tool (5). An operating stop (120) is fixed relative to the housing (2) and a counter-body (110) is arranged on the protective hood (51) and corresponds to the operating stop (120). The operating stop (120) is designed as an energy absorption element which, in the event of an excess load acting on the operating stop (120) due to the counter-body (110), moves away from the counter-body (110) in order to absorb kinetic energy of the protective hood (51) and to protect components of the counter-body (110). The work apparatus (1) includes an end stop (101) for restricting the rotational movement of the protective hood (51) to an end position (25).
