The recall is being conducted in cooperation with the Swiss Accident Insurance Institution (SUVA) and addresses an immediate safety risk during operation. Users must immediately remove their devices from service until an inspection has been carried out – a typical escalation level for fire risks.

Detailed Summary

The problem lies in leaks in the fuel system of the EVC-7000 engine. Through these leaks, fuel can escape and ignite on its own under operating conditions. This poses a significant safety risk to users.

Affected consumers can enter their serial number on the website https://ssc.stihl.com/serialcheck/ to determine whether their device is affected by the recall. STIHL offers support at [email protected].
