OIL flows everywhere

I bought it in advance when I needed it. When I finally tried it for the first time, vacuum pump oil was leaking everywhere. I was just lucky, the return period has also expired. Stay away from this brand! EDIT: After taking it apart I found out why it was leaking. The bolts holding the tank are too long and reach the bottom before compressing the o-ring enough. For attachment: Remove 1 screw (metric hexagon SW 4 mm), place a washer under the screw. tighten again. Repeat for all four Allen screws holding the tank. It should now seal well. You need size #6 washers. I got a pack of 30 from a home store for $1.18.
