II. Operation
These Bagless models operate on a direct (or dirty) air
system. The air that brings the dirt into the unitpasses
the motor fan area and goes directly to the dirt receptacle,
in this case, the dirt cup. It isfiltered and exhausts back
intothe room (See diagram below). (The motor is cooled
from a separate air source.)
The carpet height adjustment lever has 4settings for
carpet cleaning and one for top tool conversion.
It is important that the unit be in the proper setting (carpet
- for cleaning, and cleaning tools - when using the hose
and tools). This will ensure optimum performance.
The cleaning tool hose is permanently attached to the
unit. The air is directed to the hose by adjusting the
nozzle control knob to the cleaning tool position• The
valve gate operates in conjunction with the height
adjustment lever. When the lever is in any one of the four
carpet settings the valve gate is open. The cam is not
contacting the valve gate•
As the lever is moved to the cleaning tools position the
cam locks onto the valve gate and slides it to shut off
suction to the agitator cavity•
Note: The illustrations are shown without the bottom
plate or wheel assembly in place.
