Legacy models. Fig. 1.
All models were introduced initially with:
,, Molded, integral handle grips
• On/Off switch on the front of the upper handle
• Two brush agitator (Replaceable Roll Sleeve)
• Extra bag and belt storage on the unit Fig. 2
• One 12v headlight
• Hard bag enclosure
• One speed motor
• Stair cleaning handle
• Four position carpet height adjustment Fig. 3
• Top tool conversion
• Triple stretch hose
• Tool storage on the front of the unit
• One molded extension wand
• Type Z mlcrofiltratlen throw away bags

The cleaning tool hose attaches to the cleaner
through the top of the hood and CAN stay attached
at all times.
When using cleaning tools, the nozzle control must
be in the #5 cleaning tools position. Fig, 5
Withthe nozzle control inthe number 5 position, a
valve gate in the main body closes and blocks all air
flow from the agitator cavity therefore diverting it to
the hose.

I. General
These uprights are lightweight upright vacuums
that feature high performance computer design
motors, double edge cleaning, quick release cord
wraps and top conversion cleaning tools
ON/OFF _
SWITCH
All models have automatic height adjustment in
that the nozzle is free to float up and down on the
carpet. These models additionally have front
wheel height control to limit the minimum nozzle
height which allows the user to "select the proper
setting for optimum operation on various types of
carpets.
The Legacy and Legacy II models use Type "A"
top-fill disposable bags.
The Dimension/Dirt Finder uses Type "Z" top-fill
disposable bags.
Microfiltration bags are available for both models.
II. Operation
These cleaners operate on a Dirty Air System
principle, i.e., dirty air passes through the motor
area (fan) before reaching the bag.
II
Fig. A
The carpet height adjustment lever has four
settings for carpet cleaning and one for the top too!
conversion.
NOZZLE CONTROL
KNOB _,_
It is important that the unit be in the proper setting
(carpet - for floor cleaning, and cleaning tools -
when using the hose and tools). This will ensure
optimum performance.
The cleaning tool hose attaches to the unit through
the tool door located on the top of the hood. The
air is directed to the hose by adjusting the nozzle
control knob to the cleaning tool position.
=o CLEAN AIR
,o DIRTY AIR
As illustrated, air and dirt are sucked through the
molded agitator housing and directed into the
motor area. The fan then propels the air and dirt
up the handle passage and into the throw-away
bag.
The Legacy units are controlled by an on/off switch
located on the side of the unit. (Fig. A)
The Legacy II, Dimension and Dirt Finder units are
controlled by an on/off switch located in the front of
the upper handle. (Fig. B)
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.

III. Disassembly
Models with a bag door skip to section B.
A. Outer bag (Legacy and Legacy II Models)
1. Release jacket support upper from bag strap
(Fig. 1).
Note: These illustrations are shown without the
bottom plate or wheel assembly in place.
Dirt Finder feature:
The embedded Dirt Finder system is powered by a
regular 9V alkaline battery. The battery is located
in a holder inside the bag compartment.
The circuitryis energized when the cleaner on/off
switch is tumed to the on position. A separate
switch mounted in the bag housing is actuated by
a raised rib on the upper switch rod.
A microphone, located near dirt duct, senses
debris that strikes the tube and signals the circuit
board which controls the lights.
The green light signifies clean and the red dirty.
It is important to note that when you turn on the
unit the red light will come on. After a few seconds
the rod light will go off and the green light will come
on. This function lets you know the Dirt Finder
feature is ready. If this lighting pattern does not
occur check the troubleshooting portion of this
:instruction.

housing.
2. Snap circuit board out of housing and
disconnect leads.
Note: The discharge of static electricity to a circuit
board can damage the component. When
removing the circuit board from the special
anti-static bag, the following precautions should be
taken.
a. Avoid being statically charged when handling
board. Serviceman should ground himself if
possible.
b. Circuit board should be handled by outside
edge or metal heat sink only.
c. DON'T touch the metal traces (circuits) on
bottom of circuit board•
F. Microphone
The microphone is housed in the bag housing
above the opening for the dirt duct (Fig SH).
To remove:
1. Grasp microphone leads near the base of the
microphone and slowly pull the mic out of the seat.
