A hedge trimmer has at least one cutting blade and an internal combustion engine operatively connected to the at least one cutting blade so as to drive the at least one cutting blade reciprocatingly. The internal combustion engine has an exhaust gas muffler with an outlet for discharging exhaust gases from the exhaust gas muffler. A multi-part exhaust gas pipe is connected seal-tightly to the outlet of the exhaust gas muffler and connects the outlet of the exhaust gas muffler to an outlet opening where the exhaust gases exit from the hedge trimmer. The multi-part exhaust gas pipe has a plurality of pipe sections, including at least a first pipe section and a second pipe section, wherein the second pipe section is embodied separate from the first pipe section. At least one of the plurality of pipe sections is made of plastic material.

A work apparatus has at least one handle () and a drive motor (). The handle () is connected to said drive motor () via at least one anti-vibration element (). The anti-vibration element () is held on a first housing part and coacts with a second housing part. To achieve good damping, the anti-vibration element () includes a damping section () having an annularly-shaped wall () which expands in the direction of the second housing part.

Work apparatus

An internal combustion engine having a cylinder, a fuel-supply mechanism, and an elastic connector for connecting the fuel supply mechanism to the cylinder. The connector has a first channel for fuel/air mixture and a second channel for combustion air. The connector has a first connection end and a second connection end at which the two channels open out. The two channels are separated from one another by a partition that extends in the longitudinal direction of the channels. The partition is twisted about its longitudinal central axis between the first and second connection ends to achieve a great elasticity of the connector. To produce the elastic connector, a respective core is used for each channel, and the cores are moved relative to one another to enable removal of the connector from a mold.
