Is it’s already assembled? If not you level each section as you assemble it. If assembled roll striped ball slowly down the side long rails, see which way ball Moves. If you line the stripes up sideways You I’ll see it start to wobble one way or the other and the ball will track off one direction. Slowly means just fast or slow enough for the ball to touch end rail.

Note that direction down the rails and roll it cross corner to corner long ways. You have good idea Which side low or high. The Long level should show this also. As mentioned if no leg adjusters you have to shim up which ever side is low. I use to use it pieces of Card board paper. If on carpet you’ll have to check it several times till the table settles. Shim till the ball will roll straight 2” off rail providing you hit exactly center of the ball.
