How to use
To transport
To move your cleaner from room
to room, put the handle in the ,p-
right position, tilt the cleaner back
on the large rear wheels and push
forward.
Handle adjustment
The handle of your cleaner has
three positions: Upright for stor-
age and when using attachments.
Operating for general operation on
carpet and foors. Low for reaching
under low furniture. The handle
can be lowered by stepping on the
pedal on either side at the rear of
the cleaner. (Some models have
only one pedal. )
ON-OFF switch
To turn cleaner ON, push switch
down. To turn cleaner OFF, push
switch up.
Some cleaners are equipped with
a two-speed switch. When the
switch is pushed up as far as pos-
sible, it is in the OFF position.
LOW SPEED is to be used for less
vigorous cleaning and reduced
suction on delicate carpet, rugs,
and non-carpeted floors. Slide
the switch down one notch from
OFF to LOW speed.
HIGH SPEED is to be used for
cleaning most carpet and for use
with attachments. When the
switch is pushed down as far as
possible it is in HIGH speed.
Note: When cleaning any floor
covering, turn cleaner "OFF"
when unattended, particularly on
non-carpeted floors. The agitator
cleans so thoroughly that opera-
tion while the cleaner is stationary
may mar the floor covering.

Special features
Edge cleaning
Brushed edge cleaning is provided
on the right side of the cleaner to
remove imbedded dirt in carpet
near baseboards and furniture.
Guide the right side of the cleaner
parallel to the edge of carpet or
furniture for brushed edge clean-
ing.
Standard edge cleaning is provid-
ed on the left side of the cleaner.
Standard edge cleaning removes
surface dust and litter.
Adjustment for carpet
pile height
The cleaning of carpet and rugs
takes place at the nozzle. This is
the opening at the bottom of the
cleaner where the agitator is lo-
cated.
It is necessary for the nozzle to be
adjusted properly to the various
carpet pile heights. The adjust-
ment lever on the front of the
cleaner may be set on three differ-
ent self-adjusting ranges.
On very dense pile plush or shag
carpet, some difficulty in pushing
the cleaner may occur. In this
case, position the adjustment le-
ver on PLUSH or SHAG.
When cleaning non-carpeted
floors, set adjustment lever to
LOW/MEDIUM and use LOW
SPEED, if available on your
cleaner. Because of the vigorous
action of the agitator, do not
allow cleaner to run in a sta-
tionary position on any floor
covering, as marring may occur.
Disconnect cleaner from electri-
cal outlet before making nozzle
adjustment.
To change nozzle adjustment
grasp the handle and tilt the
cleaner forward. Move the lever
with your hand until it "clicks" in-
to the desired position.

Cleaning Tools
This cleaner may be used with cleaning tool attachments. Some models

Maintenance
The following sections are concerned with proper maintenance of the
cleaner. Familiarize yourself with these home maintenance tasks and
keep this owner's manual in a convenient place where you can refer to it
when needed. Proper use and care of your cleaner will assure continued
cleaning effectiveness.
11

The bag
Your cleaner has a durable outer bag which covers the throw away bag.
A light wiping with a damp cloth will keep this outer bag clean.
When to replace the throw away bag
Check the bag from time to time. It is recommended that you change the
bag when the dirt reaches the dotted line on the throw away bag. If you
let more dirt than this accumulate, your cleaner may not operate effec-
tively. Change bag frequently when using cleaner on new carpet, due to
rapid accumulation of carpet fluff. Also check dirt duct (see section fol-
lowing belt replacement) for fluff accumulation.
Where to buy bags
Bags may be purchased from your local Authorized Hoover Dealer or
from a Hoover Factory Service Center. When ordering bags, be sure to
give the model number of your cleaner.
What bags to buy Hoower®
Use HOOVER bag type A with this cleaner.
To assure that your HOOVER cleaner operates at peak per- f,_'_
formance, it is imperative that you use only genuine
HOOVER throw away bags made by The Hoover Company.

under the Hoover design and
quality controls, may not operate
the agitator correctly and may
damage your cleaner,

Dirt duct and dirt tube
To maintain the strong suction
and cleaning effectiveness of your

cleaner picks up a larger object
than can be exhausted in the bag,
it can be caught in the dirt duct or
dirt tube. These are easily cleaned
out by the following methods.

cal outlet.
For access to the dirt duct, turn
cleaner over to expose underside.

cal outlet before checking
brushes.

bristles do not touch the edge of a
card held across the nozzle, they

place both brushes at the same
time to maintain cleaning effec-
tiveness.
