To remove the power nozzle, or front head of the vacuum, first make sure the unit is turned off and is unplugged. Press the Toe-Touch pedal all the way down. Then, raise the headlight hood, pull the belt lifter handle toward you and turn it counterclockwise until the red arrows line up. Once the read arrows are lined up, turn the Accessory Lock counterclockwise, which will release the Power Nozzle. Now you may remove the nozzle and attach your next accessory and lower the hood. To re-attach the power nozzle, follow the steps above to remove the attached accessory. Once that is off, the belt on the Power Nozzle should be stretched on the hook inside. (If it is not, flip out the belt lifter handle and turn it counterclockwise until the red arrows line up. The hook should catch and stretch the belt inside.) Rest the two hooks on the rear of the Power Nozzle over the attaching bar on the front of the vacuum. Then push the nozzle against the unit and turn the Accessory Lock clockwise to lock in place. Flip out the belt lifter handle and turn it clockwise until the green arrows line up. This will release the belt from the hook to spin the brush roll.
