You should check collimation before each use...
Generally speaking, with a "tube" reflector after you get the secondary set up properly it most likely won't need much adjustment unless you put the scope through some sort of traumatic experience...
The primary will probably be the place to make your adjustments each new time you go out...
But, do follow, the whole checking process each time.
Also remember that collimation can and does change as the temperature of your mirror changes...it is best in my opinion to let the scope/mirror cool before doing the "final tweak" collimation prior to viewing.
After a time or two, the whole process will only take a few minutes and will become second nature to you.
Good Luck and Happy Viewing!
