Trimmer advances the trimmer line very quickly. The spool is empty before i can finish my yard. When new, i had plenty of line left when i finished the yard. Is there anything i can replace to fix this issue?
For model number LST136B

Hi Dianna,
Thank you for your question. If your trimmer is feeding too much line, there are some parts that you will need to check to see which one is causing the issue. You will need to check the guard, the lever, the spring, the cap and the spool. We have included a link that you may reference on how to check these parts. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. We look forward to hearing from you!
