Abstract
A work apparatus has a motor for driving a tool, an operator-controlled element for the motor and a blocking device. The blocking device has an actuating element having a blocking position and an unblocking position. The operator-controlled element is blocked for the operation of the drive motor when the actuating element is in its blocking position. When shifted from the blocking position into the unblocking position, the actuating element is moved in a first direction and in a second direction. The first direction is into the housing part and the second direction runs perpendicular hereto. A compulsory guide is configured to, during movement of the actuation element in the second direction from the blocking position in a direction toward the unblocking position, initially move the actuation element in a direction opposite to the first direction before the actuation element can be moved in the first direction.
