Bleeding woods BH7500

[stanley7140]

I've got a woods BH7500 that is self contained and runs off the PTO on my JD4200. I've dug several holes and 50' of 36" trench with the 12" bucket and all in all it seems to work really well, but it seems like there is air in the cylinders. I was under the impression that the system would be self bleeding once it was used for a while. I haven't been able to find anything about bleeding the system in the manuals.

Anyone know how to make sure there isn't any air in the rams?

Thanks

Running each cylinder a full stroke should bleed out any air that you may have.

Thanks, I figured it would be self bleeding. I though I had run all the cylinders to full stroke, but after looking at it again today I realized I have never had the boom all the way down (I've never had the tip of the boom below grade). Looks like I get to dig another hole.
