2. Remove the hood by loosening the two fasteners
located on the top of the hood and lifting upward.
These fasteners need only a quarter turn to lock or
unlock the hood. (See padlock graphics on the hood.)
4. Check for blockages in the brush roll area and remove
any obstructions found there. The base hose can be
cleared of any blockage by using a blunt instrument.
