Looks like was disturbed. Can you screw valve a little? If that helps a little more. Do have pressure gauge on panel? What's it read?

SOURCE: my excavator hitachi ex200-1 weak swing and when you swing then stop vibration begin on turn table when i stop to swing,and when i swing and lift cylinder raise,vibration on the turn table will contin

Not sure would need to have a good look ,but i suspect a safety valve isnt closing properly causing thumping within the hydraulic system which is the vibration you can feel,shouldnt cost a lot to repair providing the faulty valve can be located so return to the dealer as they will have a good idea as yours isnt the first to go wrong iam sure

How do i go about finding a service manaul for my Hitachi EX60Mini Excavator? I was told it was a grey market machine by the dealer.


go DownloadAManual.net and there is a manual listed for hitachi ex60-3 excavator service manual download
The dealer may be saying that it is a japan machine made under licence in china and is not covered by the hitachi warranty properly and because of that dealers are reluctant to work on them as they are considered inferior product

Is there an adjustment to increase hydraulic power on Komatsu pc35mr-2 mini excavator? Or is there a sensor that is responsible for relationship between engine rpm and hydraulic operation?


you assumption is right
the pump is operating at idle as at full rpms and is controlled by pressure relief valves
When demand for pressure is low the valves will be partially opened and will operate when the pressure is reduced ( ram valve is moved)
Higher rpms maintain the pressure for faster ram operation
I would suggest that you have the system pressure tested by a service centre as it could be a malfunctioning valve (solenoid) or a failing pump

Hitachi UHO 25 excavator is giving a problem. What happens is that the machine starts and the track moves but suddenly locks one side. I have changed the centre joint kit and serviced both track motors but...


I have the same problemon my UH025-7 after a year of troubleshooting we finally found it to be the hydraulic pump itself. This pump is a multi stage pump with one part of the pump operating one track and another part of the pump operating the opposing track. Track would start to go then drop dead. If I eased the levers forward it would move a little before one track would drop dead again. My problem is finding a pump. Al Drewett toledofiberglass@bellsouth.net
