Yours has small sheet metal wheels, and was likely fabricated by knowledgeable and observant folk.
Most machines in that class today, can seemingly be quite a bit trickier to level,
which is apparent if watching someone feeding something long or heavy enough,
is usually a good way of spotting, (providing they don't edit this out, as per usual with a small machine cutting)
and have cast iron wheels which ain't so easy to repair, (should the boss of the wheel be substantial enough to bore out and insert sleeve)
Moreover, we haven't an idea of the size of the saw, which compounds alignment errors the larger the machine gets,
so figured it was worth mentioning how to use a plumbob sensibly,
for giving the machine a decent inspection, on a thread with such a title...
Should it actually be a floor standing model, and perhaps the floor being equally as bad, it might get quite tippy, even with wedges underneath.
Might be a PITA to move into a certain location if one has no choice about where it can go, so with all that, in worst case scenario, good to know where one stands.
Even with one finger, one can rock most machines about easily pressing somewhere on the upper cabinet.
