I've been going through the shindaiwa www site and couldn't find any info on how to tune-up your t-260 trimmer. I was wondering if some of you guys could give me some feedback/input on how to tune a t-260. I just bought a t-260 for $180 CDN USED. It's only been used for residential use. I want to tune this puppy up before I start up, but I dont know what I need.
