Abstract
A manually guided implement is provided and has an internal combustion engine and a power take-off housing to which the engine is secured. A centrifugal clutch is provided for achieving a positive connection, as a function of engine speed, between a drive part, which is driven by the engine and is rotatably mounted on the engine side, and a power take-off part that is rotatably mounted in the housing. The clutch has at least one centrifugally actuatable clutch body in the region of the drive part, and in the region of the power take-off part has a clutch housing that overlaps the clutch body. The clutch furthermore has a locating bearing that is disposed between and coaxial with the drive part and the power take-off part. Locating pins are provided for aligning the engine relative to the housing, with the pins extending with play into appropriate receiving openings.
