DETROIT (WWJ) - More than two million power tools for the yard are being recalled because of a potential fire or burn danger.

The Consumer Product Safety Commission said the recall involves gas-powered STIHL trimmers, brushcutters, KombiMotors, hedge trimmers, edgers, clearing saws, pole pruners, and backpack blowers that utilize a toolless fuel cap.

The level of ethanol and other fuel additives can distort the toolless fuel cap, allowing fuel to spill, posing a fire and burn hazard.

In all, about 2.3 million tools are being recalled.

The tools were sold at authorized STIHL dealers nationwide from July 2002 through May 2011 for between $190 and $650.

STIHL has received 81 reports of difficulty installing and/or removing the fuel caps and fuel spillage. No injuries have been reported.

Consumers should immediately stop using these products and return them to an authorized STIHL dealer for a free repair. It is illegal to resell or attempt to resell a recalled consumer product.

Consumers can contact STIHL for instructions on identifying these toolless fuel caps at 800-233-4729.
