This hedge clipper is only a bit over 2 years old (naturally-out of warranty), and the blades won't move. I've checked the blades carefully and can see no debris which might jam the unit. When you rev the engine, it just bogs down as the blades won't go. The last time I used it, a week or so ago, it was fine as the blades moved freely prior to shut down at which time I usually spray the blades with WD-40. Anyway, I find it hard to believe a bearing could seize so early in its life, especially since it has seen limited duty, being used only on my own yard. So, I was wondering if anyone has any ideas before I tear it down.
