15" Trimmer low speed is too fast

I have a brand new 15" string trimmer and am concerned that the variable-speed switch is malfunctioning.  When I squeeze it as gently and slowly as possible, at a certain point the head pops on at a moderately fast pace - too fast for delicate trimming (fast enough to hear it whirring).  It is normal that the head spins at a moderately fast speed as its slowest rate?  This is my first experience with a variable-speed batteried tool.  I expected an ability to have very precise low-speed control for around my fencing and house, as I have with my gas unit, but the slowest speed I can get will damage my property or chew up an excess amount of line.
Thanks in advance for some experienced feedback!

I agree, I had the same issues, it slows and speeds up like crazy when not needed. Thought I could use it as an edger - it spins wildly but doesn't cut evenly...too late for me to return though :(

Kevin, my experience with the 15" trimmer is that the lowest speed is actually too low to do any useful trimming and is barely enough to keep the string taut.

I would suggest there may be something wrong with your trimmer. The next time you're at Home Depot you could ask them to put a battery in their floor model to compare. If going to HD isn't convenient you can give Ego Customer Service a call and see if they have a better option.

So.. here is a bit of info. My neighbor has a 15" trimmer and it acts as a 3 speed more than a variable speed, mine is smooth and slow on the ramp up, true variable speed. So.. some possibly have less accuracy than others. Probably due to the potentiometer in the control handle. If I had that and I didn't like it, I would put a new potentiometer in. But that is just me. Sometime these things aren't as accurate as the next one and it is the control circuit.

Just an FYI.

So any suggestions on which potentiometer we can use and can we rig this thing ourselves without breaking warranty ??

Not a chance, any modification will void your warranty.

Here is something to try: activate the trigger at the point furthest from the pivot (e.g. near the tip), because that will maximize you ability to feather the switch.  but it really does sound like a defective switch (as stated above).

If you took it apart, you could find a model number on the pot and get one, replace it, and no one would know. It's your tool.
