CPSC campaign 11711
Hazard
Vibration from the ignition module may cause the trimmer head to loosen and detach from the mounting, posing an injury hazard.
Remedy
STIHL informed purchasers for whom they had addresses directly by letter after April 15, 2010. Consumers should stop using this trimmer/brushcutter immediately and take it to an authorized STIHL dealer for a new ignition module, which will be installed at no cost to the consumer.
