Raise/lower valve has slight ‘weeping’ leak

[NaturalSight]

I am a new owner of a 2013 Alaskan 10 that came to me without an owners manual and have a couple of questions about the hydraulic system. First, every time I raise/lower the camper, my hand has hydraulic fluid on it. Not a lot and I can’t see where it is coming from. It may not be worth the trouble to fix. Is there a way to check and see if the fluid level is low? I see what looks like a threaded fill plug at the top of the black reservoir above the hydraulic pump. I assume that this is where I should add fluid is needed. I am sure that I can search the threads here to find what kind to add. I don’t know what type was used before and am guessing that it is not advisable to mix types. Advice?

Yes that is the fill hole, use a straw or something to see how full it is. Pour carefully as it can be quite a mess.I use John Deer hydraulic oil in my 2014. And yes there is some seep in mine as well. Age perhaps. Good luck.

Do you fill it in the ‘up’ or ‘down’ position and how full should the reservoir be?
