I exchanged one 128LD for another 128LD yesterday, and 2 out of 4 times when I tap the head on the ground, the quick release/detach button would seem to dislodge and make the lower portion of the shaft spin. Is this something I can adjust or do I need to return it to exchange? I can't duplicate the effect by turning it with my hand, it only seems to happen when I use the bump feed.
I did follow the instructions to a 'T', as I can't always afford new expensive toys all the time, and I want to take care of it, I even used Husqvarna's pre-mixed 50:1 fuel.
It should be fair to mention that I had a previous 128LD that I returned to Lowes to get this new one as it was missing the pre-installed bolt off the shaft connector's rear.
Edit, UPDATE: tried to tighten the bolts on the shaft with no luck, returned to store to get replacement, now this one has a whole new set of issues. Either my mixture isn't right (doubt it, the previous 128LD was running off the same mixture), or there is an air intake issue.
