I have a Echo PAS 260 trimmer which gets extremely hot... After running this machine for 10 - 15 minutes it gets too hot to touch anywhere near the head or cone part of the powerhead. I also have a 230 and it seems to be fine; not near the same heat. My 260 gets to hot to rest the top of the head on your elbow area if you know what I am talking about. Any suggestions as to what the cause is, or is it normal for it to get this hot? Ps. there is not discoloration around the head or unusual noises.
