Hi my name is***** will be glad to help. With the oil at operating temp does it go above the sight glass? I want to be sure it is not just slightly overfull and there is air space at the top of the tank. Also what position are all your attachments when checking the level?
Please post the full model and serial number of your machine.
I thought actually it was hoe folded up and the loader bucket and cutting edge flat on the ground. If that is right then it could be the extra oil from the cylinder when lowering the bucket to the ground position coming out of the vent.
The oil level always rises after operating temp so the middle of the glass is best. Are there any other operational issues with this machine?
If there is not a problem with the level and air space top of tank then the only other thing I can think of if a problem with pressure bypassing somewhere to the return side of the system.
The hydraulic system takes a while to come up to operating temp is below 180f. Anything above that will break down the oil and will start to cause problems.
Yes you are correct. I just checked as well and the outriggers must be retracted as well and boom to the side position.
It does not. I am speaking from experience. I always go the middle of the glass cold if hot maybe 3/4 up
That is what I suggested earlier.
"If there is not a problem with the level and air space top of tank then the only other thing I can think of if a problem with pressure bypassing somewhere to the return side of the system."
If this is the case it is an indication of a component problem allowing pressure to the return side. further testing of return and case drain pressures would be needed to isolate this.
