ABSTRACT:
The invention relates to a work apparatus such as a motor-driven chain saw having an internal combustion engine equipped with an electrical ignition system. Combustion air is supplied via an intake channel and fuel is supplied via a carburetor. The intake channel is provided with a throttle flap and the carburetor with a choke flap. The choke flap is displaceable into a start position by means of an actuating element and a start linkage. In this position, the throttle flap is latched in a pregiven open position. The actuating member for the choke flap is mounted in the forward end portion of a handle attached to the housing and extending in the longitudinal direction thereof. In addition, an operator-actuated lever is configured so as to project outwardly beyond the housing of the handle. Because of this arrangement, the latching between the throttle flap and the choke flap is obtained in a simple manner by latching of the throttle lever journalled in the handle with a switching shaft.
