My hedge trimmer has never worked correctly. I bought it because my neighbor has one and I had used it with great success. My trimmer stalls out, the cam slips, and it just won't cut. This past weekend I tried to use it again anf this time the blade action slowed down and it started to smoke. I shut it off and had to trim a small pine trewe by hand. Is there a service shop I can take this trimmer to or send it back for service?:
