As usual, it depends. If the foot is light and the motor is heavy, probably a good idea to restrain. If vice versa, probably no biggie. It is hard to tell from the Harbor Freight ad image about the weight distribution.
I did wonder about your seismic zone, though. While rare in my neck of the woods, earthquakes tip things. I believe you are in MN, which is a sleepy seismic zone per the maps I find, but I have never done calcs there. Sandbags were a decent suggestion if concerned about general tipping/bumping, but in a seismic event, all the mass moves together, and hard mounts matter (and before natural building people flame me, I add an earthbag building caveat here: that structure has huge damping with almost no rigidity, and is seismically sound for that reason, a different problem entirely).
On the flip side, (and depending on your toolkit) you might not find it hard to anchor with two Simpson Titens or equivalent, 10min with a rotohammer and a driver should be about all it takes. Is it a rearrangement option that you want to keep? If so, there are flush anchors that bed the female thread in the floor, so you drop in a bolt. But it's your shop, your rules, your risks, your time and money. I would summarize anchoring as a good but not necessary step.
Tangent becauee it was suggested: I have a Milwaukee mag drill press myself, and while it is useful, it is nowhere near as rigid as a proper shop tool. I bought it to do steel on jobsites off generator power, and it did that well. Now, when I want to use it at home, I have to set it on a welded beam structure to have a magnetic grip, and I can still tip it against the magnet if I don't go easy on feed rates. Unless space is ultrapremium or you have to have a mobile shop, I think the floor press is a good choice. Plus, it is a heavy and tippy sonofagun, and there is a reason the manual talks at length about safety chains on the tool.
Happy hole-drilling!
