I have 6 power settings and only use it on the lowest setting (1). I have used it on setting 6 a couple of times but is just a waste of power and runs down the batter a lot quicker than setting 1.

Most importantly is making sure the long strands of grass and vines don\'t wrap around the spindle assembly - which is what eventually caused the failure of the original product. I was really amazed at the reasonable price of these parts given how expensive the electric weed trimmer is. I usually run the battery powered 40Volt weed trimmer for about 1 hour per week on average. I am pleased with the repairs using these parts and would do it again.
