Backhoe Extra noise

[farmboy238]

While digging around a stump with my new Kioti DK45se HST and KB2485 backhoe there developed an extra noise in the hydraulic controls of the backhoe. I tried to upload the video here but never could get it to go so the video can be viewed on YOUTUBE at Farmboync titled 12 19 14 1213pm extra noise. Anyone have any ideas what it might be? Only 4 hrs on tractor and maybe an hour on the backhoe.
Thanks for your help...

Is your hydraulic oil right up to the mark?
If it is, then I can't help you.

The hydraulic oil is within 1/4" of being to the top most mark. Thanks for getting the video over for me>> I was wondering if maybe being new there was some trash going through the system, because it quit and I ran it at least another half hour with no other extra noise...

Top off the hydro oil. Sounds like it could have been some air in the lines. System should self prime. With only 4hrs on the machine air pockets may not have worked their way out.

Any hoses kinked?

Just a few possible causes. Others may have more insight.

Nice machine.
