Engine vibration during use of the trimmers can cause wear on the fuel line, leading to a propane fuel leak.
This recall involves the Fiskars SmartPower Propane 4-Cycle Straight and Curved Shaft String Trimmers.
Both trimmers use propane fuel.
"SmartPower" is printed on the lower shaft and near the pull-start handle.
"Fiskars" is printed on the engine cover and on the plastic cutting guard.
The trimmers are black, silver and orange.
They were sold online through various sites including Amazon and Walmart from January 2011 to July 2011 for between $220 and $280.
Consumers should immediately stop using the recalled trimmers and contact Fiskars to receive a full refund.
