It's a good idea to try to remove as much of the oil from it as possible. If the machine it was on before had a catastrophic failure the oil could have metal shavings in it or if it's been sitting for a while the oil could have water in it.
I would remove the hoses and flush them with mineral spirits, then blow them out with compressed air. With hoses off you should be able to work the cylinders in and out by hand to force most of the oil out of them in to a clean container. If that oil looks cantaminated then you will need to flush them too.

Another way is to hook it up to your quick attach, remove the couplers and tilt forward and drag the bucket so it opens the clam. This will force the oil out of the rams. This will save you removing pins and what not to push the rams sticks in and out to flush what oil you can out.
I'm sure you'll love your new bucket, all my machines have 4 in 1 buckets
