I am having problems with reloading the cutting line in my new ST1520 as per the instructions on page 24 of the owner's manual. The cutting line broke off past the eyelet on one side. There is approximately 4" of line protruding out the other. In particular, my problem is with step 2 on page 24. My hand isn't big enough to reach around and press the release tabs at the same time. Am I missing something here?
