I've never seen a Pistorius VN-s underpinner, but eager to learn about it. Is it pneumatic or manual? Can you post a photograph?

The one with that little clear dome is the one you put the oil into - use air tool oil /pneumatic oil. After all the pressure is released you should be able to unscrew it by hand. Fill it less than half-full. That clear dome shows you how fast the oil is dripping when the nailer is recycling and you only need like one drop every minute.
Thank you for your answer but I didn't get how to open it . Attached are two more photos .
The left cylinder is empty the right one has oil.
The little clear dome on the right hand side on the top ?
Or on top are 6 screws - should I unscrew them ? Or under the left cylinder is black plastic handle should I try to unscrew from the bottom ?
Thank you for your help !!!

Yes the one on the right. The two bowls are pressure locked so you have to first bleed the pressure to zero. Then grasp the bowl on the right with your hand and unscrew it (counterclockwise). If it's a beast use a strap wrench. That little clear dome is the drip indicator and that little screw next to it is for adjusting the drip rate. You should see oil dripping inside that dome and you want to see it drip maybe once a minute.
The one on the right has oil and I unscrewed on the left . Thank you . It was totally empty and after I cleaned it and pour oil little higher that the line...
I'm going to put it back and start the compressor . I hope I did all as you said.
Please correct me if I'm wrong . Is it correct Oil for that? See attached pictures
Thank you again

NO! The left one is supposed to be empty. The oil goes into the bowl on the right! The left one is the filter/water separator.
OK, I thought because the left cylinder is empty , vnailer makes air noise every time when I put vnail in the moulding . Also if I pull the handle up ( release air handle on top ) it's constantly releasing the air . Never happened before .And when I release the pedal to let clamp out of the moulding it makes air noise and then goes out . Those are new recent symptoms and when I saw empty cylinder I thought "this is it "... but you are saying that left cylinder should be empty.
I just put empty cylinder back and turned on compressor. So my consern is: when I release knob ( see photo ) it's constantly releasing air . When I put vnail in its also make psss ( air ) and then insert vnail , and when I release pedal to release the clamp , clamp has delay releasing - like thinking and then with psss (air ) releasing ...
it start to happen about month ago ...something is wrong but I'm totally lost . Thank you for your time and help. Love to call you to explain better.
