My table saw is set up like that. I found that the hinged caster plate
should hook to the base so it doesn't flip out when a wheel hits
something. You could put fixed feet under it as well so you don't have
to tip it very far to toe-flip the casters in or out.

There is one fixed and one swivel caster on each plate, with the fixed
caster aligned toward the swivel one so it prevents the saw from
rolling sideways when I lift the other side.
