I have had the EXACT same problem with the EXACT same trimmer! The first one did this 2 days after I bought it. I took it back to Lowe's, was refunded the money, and bought another 223L. The second one lasted 1 month. Im so dissapointed in husqvarna. I did my research before buying a $200+ trimmer and purchased the 223L because it is a true Husqvarna, not a poulan pro. If my father-in-law and I cant fix it Im taking it back and then buying a Stihl. Absolutely rediculous.
