Zusammenfassung:	A guard for an intake channel or blow channel of a power tool has a first rib with a longitudinal direction, wherein the first rib has a first rib section that extends along the longitudinal direction of the first rib from a first end to a second end of the first rib section. The first rib section has an inherent frequency. One or more first disruptive bodies are arranged on the first rib section between the first end and the second end of the first rib section. The first disruptive bodies are configured to translatorily vibrate together with the first rib section. The first rib section and the one or more first disruptive bodies form a vibration system with a system inherent frequency, wherein the inherent frequency of the first rib section is different from the system inherent frequency.
