Oreck XL9100 Brush clogged with hair

\015 Does anyone know how to dismantle the brush for the Oreck vacuums? They appear to be the same for the newer models. I’ve had to replace several brushes due to hair, or whatever, clogging up the brush so it won’t turn. I’ve tried getting a pocket knife in there but it won’t really get the hair that’s hidden and stopping the brush from turning freely.\015 – Oreck XL Ultra Bagged Upright Vacuum
