@ The Hoover Company 1969

For greater convenience and ease of operation,
this Deluxe cleaner provides you with an ex-
clusive Automatic Power Drive feature. The
Automatic Power Drive Control is built into the
handle of the cleaner. This automatic drive
propels the cleaner forward and backward at
a variable rate of speed controlled entirely
by (you) the operator. (Fig. 1)
Forward - To operate the cleaner in the
forward position using the A-utomatic Power
Drive, push the handle grip forward. (Fig. 1)
Notice that the cleaner moves in a forward
direction with little effort. The speed at which
the cleaner moves is controlled entirely by
(you) the operator.
Reverse -To operate the cleaner in the reverse
position using the Automatic Power Drive, gently
pull the handle grip and guide the cleaner toward
you. The cleaner moves both forward and back-
ward with the same ease when using the Automatic
Power Drive feature.
NOTE: For best results guide the cleaner gently
at first until you have adjusted to the ease of
operating the cleaner. The Power Drive feature
is in operation only when the motor is turned on.
To move the cleaner without operating the motor
use the transport button (disengage drive) accord-
ing to the following instructions:
TO TRANSPORT
Your Hoover Power Drive Cleaner can be transportel
by two (2) methods:
1. Use the convenient carrying handle for carrying
your cleaner up and down stairs or when lifting
the cleaner from one surface to another. Lift it
as shown in Fig. 2
2. To roll your cleaner from one room to another,
use the convenient button located on top of the
handle grip (Fig. 3). Press the button and slide
the handle grip up or down the handle until the
button drops flush with the handle grip. With
the button depressed, the cleaner is in the trans-
port or neutral position, with the drive mechanisr
disengaged.
While holding the button depressed, the cleaner
may be pushed to the desired location as shown
in Fig. 4. When the button is pressed in, the
Automatic Power Drive gears are locked into
neutral position and the cleaner can easily be
transported.

THIS IS THE “HEART” OF YOUR NEW
HOOVER POWER DRIVE CLEANER
Your new Hoover Power Drive is the most
powerful upright cleaner ever built.
To handle the wide range of pile depth of
modern carpets and rugs, two (2) adjustment
features have been provided. These features
are Automatic Rug Adjustment and Suction
Adjustment as explained in the following
paragraphs. When used properly, they will
assure the best cleaning efficiency and ease
of operation.
Automatic Rug Adjustment. The nozzle of
your cleaner is designed to float on top of the
carpet and thereby adjust automatically to the
correct carpet height for all known carpets. No
manual nozzle adjustment is ever necessary.
Suction Adjustment For Carpets and Rugs.
Set the dial on the back of the cleaner to
MEDIUM. (Fig. 1) This will be the correct
setting for the majority of rugs. On very
thin or loosely woven carpeting, it may be
necessary to move the dial toward the LOW
position.
For indoor/outdoor, sculptured or multi-
level rugs, it may be necessary to move the
dial toward HIGH for most effective cleaning.
NOTE: Be certain dial indicator points to
desired suction - not to the neutral area
between carpet and tool suction. Operate
cleaner on dry carpet only.
Suction Adjustment For Cleaning Tools.
(Fig. 2) The handle of the cleaner must be in
storage position (See Page 2) when cleaning
tools are used. When the handle is in this
position, the nozzle is raised automatically
and the agitator does not come in contact
with the rug. The Automatic Power Drive
is disengaged and the cleaner will not self-
propel.
Attach hose and cleaning tools (Page 5). Set
Suction Control Dial to HIGH under TOOL
Suction for most cleaning. For cleaning drap-
eries and delicate fabrics, move dial toward
LOW.
The dial can be placed at HIGH, MEDIUM,
LOW or any space between these markings.

HELPFUL HINTS
Don’t Pick Up Tacks Your cleaner is powerful.
It can pick up tacks, pins, paper clips, etc. How-
ever, hard sharp objects should not be picked
up by the cleaner. They may clog or damage the
hose and the throw-away bag.
Take Care of The Cord Wind it loosely, on the
cover latch and knob on Suction Control Dial,
to avoid strain. Snap clip-on plug onto cord. To
remove cord, turn cover latch. (See inset). Don’t
run cleaner over the cord - it may damage the
insulation.
The Bag Indicator (“CHECK BAG”) located on
the front of the cleaner, makes it convenient for
you to know when the disposable bag should
be changed. The indicator will normally disappear
when the motor is turned on and the Dial-A-
Matic is used for cleaning carpets. If the “CHECK
BAG” indicator appears when the cleaner is being
used on carpets, the cleaner is not operating
satisfactorily. You should:
1. Replace bag. (Fig. 3, Page 7) In some cases the
bag may not be filled to capacity; but due to
variation in size and type of dirt particles, the
bag has ceased to filter satisfactorily.
2. Check secondary filter. (Fig. 3)
3. Check nozzle hose. (Fig. 1, Page 7)
NOTE: The “CHECK BAG” indicator may be
visible when cleaning tools are used. This does
not necessarily mean that the cleaner is not
operating satisfactorily. This can be checked
by temporarily turning the dial to CARPET
SUCTION position and checking the indicator.
If it disappears, the bag does not need to
be replaced.
The Secondary Filter protects the motor from
dirt. Before installing a new bag, check filter.
Dirt spilled in the bag housing will accumulate
on the filter and may restrict motor performance.
To clean filter, remove wire holder and lift out
filter. Tap against the opening for receiving/the
cleaning tools with the suction dial set for
cleaning tool use. Replace in bag housing and
secure with holder.

ose on the cleaner carries the dirt
from the nozzle to the throw-away bag. lf the
hose becomes obstructed (which may happen if
the bag is overfilled), remove it and clear it. Pull
the hose end from the bottom of the bag housing
and unscrew hose end by turning in a clockwise
direction. Turn cleaner over, remove bottom
plate (Fig. 1, Page 8) and pull hose from cleaner.
Clean hose and reinsert it in the cleaner.
NOTE: ALWAYS DISCONNECT CORD FROM
ELECTRICAL OUTLET BEFORE REPLACING
PARTS.
THE THROW-AWAY BAG
It is imperative that you use only genuine Hoover
Throw-A way Bags mcide by The Hoover
Company. Genuine Hoover Bags can be identified
by the Hoover Medallion. These bags are made
from a special material which is scientifically
formulated to filter out dust while allowing air
to flow through freely.
Where To Buy Bags. From your local Authorized
Hoover Dealer or from Hoover Factory Service
Stations listed on the white insert. WHEN ORDER-
ING THE THROW-AWAY BAGS, BE SURE TO
MENTION THE MODEL OF YOUR CLEANER.
To Replace Throw-Away Bags. Tip cleaner over,
resting handle on the floor. Open the bag cover
of the cleaner by turning latch in either direction.
Lift bag cover. Hold throw-away bag by card-
board collar, twist outward, and remove. Discard
used bag.
To attach new throw-away bag, hold bag with
cardboard collar down and with arrows pointing
toward front of cleaner. Push hole in cardboard
firmly over tube, twisting until bag is secure.
Be sure that throw-away bag is not extending
outside of cover and that cover is in proper
position on the gasket before latching.

THE BELTS
There are two belts on your Hoover cleaner. The
belts control the speed of the agitator and the
power drive pulley and are important for the
efficient operation of your cleaner. Because of
this, when buying new belts, you should always
insist on genuine Hoover belts. Some other
belts on the market, not manufactured under
the Hoover design and quality controls, do not
operate the agitator or Power Drive correctly
and may damage your Hoover cleaner.
When To Replace Belts. Check from time to time
to be sure the belts are in good condition. If
they are stretched or cut, they should be replaced.
To Replace Belts:
1. Remove cord from electrical outlet.
2. Turn cleaner over -- remove metal plate on
bottom of cleaner by pushing latches toward
the outside of cleaner. (Fig. 1) Lift plate to
release it from clips.
3. There are two belts as shown in Figure 2.
The larger belt is connected to the agitator.To
remove the large belt, push latches that hold
agitator in and toward center of cleaner until
they are free. (Fig. 3). Lift out agitator and
remove old belt.
4. The smaller belt is attached to the power
drive pulley. (Fig. 2). To replace the smaller
belt, it is necessary to first remove the larger
belt. NOTE: It may not be necessary to change
both belts at one time.
5. Place new smaller belt over power drive
pulley and motor pulley with smooth side of
belt next to pulleys. (Fig. 2). Next, place new
larger belt over motor pulley, then over agitator.
6. Replace agitator and latch it in position.
7. Make sure that large belt is in center of
pulley, and free of agitator mountings and
latch. Turn agitator by hand to be sure that
belt is in proper position in motor pulley
groove.
8. Replace bottom plate. (Fig. 5). Make sure
that clips enter into the recesses on the cleaner
bottom plate. Check to see that latches are
pushed back and will not be covered by plate.
(Fig. 6). Place plate in position and latch
securely. Turn agitator by hand to be sure that
belt is in proper position on pulley.

THE BRUSHES
When brushes a&worn and bristles do not touch
the edge of a card held across the nozzle, they
should be replaced. Always replace both brushes
at the same time to maintain cleaning efficiency.
To Replace Brushes. Remove bottom plate, belt
and agitator following directions given on Page 8.
1. Turn end plates of agitator in opposite direc-
tions until one plate comes off.
