Abstract

A work apparatus has a work tool and a combustion engine for driving the work tool and further includes a start enrichment device for the combustion engine. The start enrichment device has a start position and is actuated via an operating mode selector. The work apparatus has a braking arrangement which brakes the work tool in the actuated position and releases the work tool in the unactuated position, and also an actuating device for the braking arrangement. To ensure that the start position can only be engaged when the braking arrangement is actuated, the work apparatus has a blocking device which prevents engagement of the start position in a blocking position. The braking arrangement is coupled to the blocking device such that the blocking device is in the blocking position with the braking arrangement in the unactuated position.
