To disable the distribution slide shaking mechanism, lift the slide, slip a thin screwdriver or other item behind the shaker wire as shown, and lift up towards you as indicated on the picture below.  We do not recommend disengaging the shaker with food larger than 1/4" diameter, but you may use other kibble sizes by trying first.
