My boss purchased a 442 at auction. (I have since learned to Google common issues before letting him bid) Anyways we have been getting some of the kinks worked out of it. One issue is we noticed that at times it is slow to swing but if you bump the right stick while swinging it will swing way faster. I have read where a few other people have had similar issues on other brands but I am not sure how to go about diagnosing it properly. I have attached the hydraulic schematics but I am not sure what I am looking for. Any advice?
