Not quite sure you are getting at in your post.
Are you talking about the 4 bars inside the blade compartment - the extensions of the collar right above the adjustment ring? Mine all go down to just above level at the 1 setting ..
right - mine too - now at the "1" position and with the doors open can you push the 4 bars down a little more ?
Without a blade in position the coller & attached bars will slide up and down at any of the adjustment positions. Once a blade is in place the bars & collar are forced to the lowest position against the adjustment ring.
Those 4 bars are attached to the collar that rides up & down the handle above the adjustment ring - can you push the bars up (from below the blade tray) when in the 2-9 positions?
What I am saying, albeit badly, is that the bars will move until there is a blade locked down on top of them - their height is determined by turning the adjuster .. You may want to see this article about Fatboy takedowns ..
