Check to ensure that the string is the correct size as specified in the owners manual. If ok check age of the string. If old it has a tendancy to be brittle. If new and supple try letting the trimmer get up to full speed and let the tip of the string do the cutting. Avoid taking on too much at once with this trimmer as the electric and battery trimmers are not as powerful as their gas counterparts. I hope this helps.
