[QUOTE="bobcatbrian, post: 36726, member: 2382"] Yes by cycling the cylinders it does take care of the air until the next time i shut it down. After about a half hour its the same thing. The reason im asking is because is has started to do it while im grinding. I was grinding last week and the wheel caught the stump and basically "walked" over the stump. The cylinder that controls the in and out of the head acted like it wasnt even hooked up. It just extended all the way out. There seems to be alot of play in the cylinders when grinding and its not the pins. I am wondering if there is anything in the control valve that can be replaced to eliminate this. Other that the seals in the cylinders, which i have replaced, there is nothing to fix there and they should not have any play when the lines are pressurized. It just seems there is alot of excess vibration because of this air problem. [/QUOTE]
