4200 excavator issue
 

Ok so I finally got all the parts I needed to fix my new excavator from shipping, running well for about 15 minutes then the hydraulics started to run very slow I filled it to what it says or so I thought I also had a few leaks in it and think I got them all tighten up. Hoses showing like it has air in system could I have a internal leak someplace or just not enough fluid as it heats up it should expand, I'm running the rc4wd fluid. Thanks for any info

I added another 75Ml on top of the 120 or 150 recommended. I had air in the lines when I ran with the manual recommended fluid level.

Mine did the same thing. Just added more fluid and kept running. Back to normal and still going.
