Hoover lV - Manual (Page 18)

Replace agitator dirt seal. Place
beveled end toward front.
Replace bottom plate by fitting
the plate over the lip at the front
of the nozzle housing. Line up
the slots over the wheels and
position holes in bottom plate
over screw mountings. Replace
screws.
Nozzle hose
The Nozzle Hose carries the dirt
from the nozzle to the extension
wand and to the throw away
bag. If the hose becomes
obstructed, cleaning effectiveness
will sharply decrease. Remove
bottom plate as described in
preceding section, and slide end
of hose out of the holder. Clear
hose and reinsert into holder.
Replace bottom plate as
described in preceding section.
Agitator brushes
When brushes become worn and
bristles do not extend past the
bottom plate of the nozzle, they
should be replaced. Hold a
straight edge across the bottom
plate to check for length of
bristles. Always replace both
brushes at the same time to
maintain cleaning effectiveness.
