Specifically, the levels of ethanol, aromatics or other additives in some gasoline sold in the United States may distort parts of the fuel cap, which could make caps more difficult to install and/or remove. If a fuel cap is not properly installed and fuel spillage results, there is a risk of fire if an ignition source is present,which could result in a burn injury to the consumer. STIHL Incorporated has received no reports of injuries at this time.
The toolless fuel caps subject to this recall can be distinguished from a newly designed cap which corrects this problem by a molded identifier mark located on the lever of the cap and also by a letter molded on the underside of the cap. These identifier markings are shown in the example photos below:
