ticket # 2236965; why should I have a Sunjow cordless chain saw? I used it for a few months; 5-7, in '22 then went on travel to Europe for 5 months, thru Feb 23. Just before I left, Dec 22, the saw would not send power to the sprocket to drive the chain; but, the battery showed 3 lights; so, it seemed to me that the battery was the issue even though it showed fully charged. OK I'll look into it when I return early March 23, 5 mounts later! just before I returned to Vrginia I ordered a new cordless saw, the same model SunJoe as the one I had. The new saw will not work with the fully charged old battery. I have returned that saw. Looking for diffferent companies saw.
