Bissell carpet sweeper how to change the dust tray

Hi I aquired 2 bissell wooden carpet sweepers and I have a part unit. Before I change the dust tray I would like some helpful hints.
Pictures will be provided upon request.
Thanks.

I discovered screws holding the dust trays together. I figured it out successfully therefore.
Appreciate all of you.
