While you do not need to remove the adjuster knob, it's likely that there is gunk in the ball bearing and spring housing plus the threads. By removing the knob from the preload cylinder (after detaching it from the bike is probably easiest to catch the ball bearing) you can quickly clean away any such grime to get the best function out of the adjuster.
