ABSTRACT:
A manually guided implement having a tool driven by an internal combustion engine, which draws combustion air in via an air filter disposed on an air filter base. The air filter is secured to the implement via a releasable securement device that includes a first securement element, and a second securement element that cooperates with the first securement element. The securement elements can be released from one another, or connected to one another, by means of a rotational movement about an axis of rotation. To achieve easy handling of the air filter, the first securement element is fixedly connected to the air filter.
