Turning these clips inward will allow you to detach the soleplate from the cleaner head. Next, remove the four screws securing the brush bar end caps to the cleaner head. This will allow you to remove each part of the two-piece genuine Dyson DC40 Brush Bar Assembly. You may now easily clear obstructions in the cleaner head or replace the brush bars with a new genuine Dyson DC40 Brush Bar Assembly. Attach the new brush bar components to the corresponding sides and turn them to make sure that there are no remaining obstructions. You may new reinsert the screws to attach the end caps to the cleaner head. Align the soleplate tabs with their inserts on the cleaner head and use the clips to lock the soleplate into position. Place the connector clip on the neck of the cleaner head and then slide the neck of the cleaner head onto the corresponding neck from the ball of your DC40.
