I recently purchased the power head with the edging attachment and the string trimmer attachment. The string trimmer attachment has it printed on the head "MAX 10,000 RPM". I cannot find anything that says how many RPM the Lo and High Speed settings on the power head output to he attachments. I'd assume if they list a max speed on the attachment there is a safety reasoning. Does the power head exceed 10,000 rpm on High? If not why is there a warning on the head of the string trimmer attachment? Wish the manuals were a little more specific than just saying Lo or High speed...

I believe it's probably a legal thing since it could be attached to something else maybe. I do not know the rpms of the motor.

Hi Eric,
I agree with Jacob and Blue Angel, it's not a problem.

I believe it was Amber who had previously posted the official specs as follows:

Low #1 = 6,000 RPM
High #2 = 7,000 RPM

And the motor is said to be 2000 watts, or roughly 2.7 HP.

I measured the shaft (no load) at 6,400 and 7,100 RPM in low/high speeds, but I was using the cheapest laser tach I could buy from China on Ebay, so the 6,000 and 7,000 RPM numbers sound quite reasonable.
