hi not been on for some time, just wondered if any one might have had same problem  I have a 26x4 schwing 1994 about 2600 hours just changed block other day I was on a slope put out boom it started to come back  so try and keep level when I flick slew to the right, (its a black & white ) I have to hold second longer  for it to move , left is okay put valve in to slow it down there are no leeks no noise there are only two valves on hydraulic line  so there is something to stop boom moving when I stop would that be in block it did happen before I changed it I can put a holding valve on but it still go's quick on right slew its as though it has two build pressure before it moves ant ideas many thanks

in case, anyone had an intrest in case it happened to them schwing made a new block as a closed circuit, so boom would not stop but went back

now have fitted a valve that stops boom moving when hands are off remote and works without being jerky

hope it helps someone
