Hi All Im looking for someone that can work on an old Hitachi EX100-2 in Walland TN, a few miles from Knoxville. The main challenge is it will only swing in 1 direction (this actually switched, it would swing right at first, now it will only swing left). I suspect the hydraulic system is dirty but I really don't know if thats the problem. I have changed filters a couple of times to try to clean it up, the innards of the last pilot filter were caved in. I dont know whether to look at the joy sticks, pilot circuit or main circuit. Any recommendations would be appreciated. Thanks Andy
