I have relatively new string trimmer... but for the life of me I cannot seem to manage the string! I load it and use it for only 5 minutes or so and the strings are reduced to mere stubbles. Admittedly I am sometimes using it as an edger and so it's striking pavement, but this is not that often. Also, I don't seem to be able to have it let out new string by tapping its base down on the ground. Finally, loading new string is obviously a 3 handed job and alas I was born with only two. CAn anyone help? Oh! I have tried different gauges of string, but nothing seems to help.
