IMPORTANT SAFETY INSTRUCTIONS

When using an electrical appliance, basic precautions should always be followed, including the
following:

READ ALL INSTRUCTIONS BEFORE USING

WARNING - To reduce the risk of fire, electric shock or injury:

• Do not leave appliance plugged in. Unplug from outlet when not in use and before servicing.

WARNING

To avoid electric shock, use indoors only.

• Never allow children or untrained adults to operate this equipment.

• Keep the area of operation clear of all persons, particularly small children, and pets. Keep

bystanders at least 25 feet away from the area of operation.

• Use only as described in this manual. Use only manufacturer’s recommended attachments.

• Do not use with damaged cord or plug. If appliance is not working as it should, been dropped,

damaged, left outdoors, or dropped into water, return it to a service center.

• Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around

sharp edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

• Do not handle plug or appliance with wet hands.

• Do not put any object into openings. Do not use with any opening blocked. Keep free of dust,

lint, hair, and anything that may reduce airflow.

• Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.

• Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.

• Do not use without dust bag and/or filters in place.

• Turn off all controls before unplugging.

• Use extra care when cleaning on stairs.

• Do not use to pick up flammable or combustible liquids such as gasoline or use in areas where

they may be present.

• Connect to a properly grounded outlet only. See grounding instructions.

OPERATING INSTRUCTIONS

INSPECTION

Carefully unpack and inspect your machine for shipping damage. Each unit is tested and thoroughly
inspected before shipment, and any damage is the responsibility of the delivering carrier who should
be notified immediately. Read all instructions carefully before operating.

WARNING

To avoid electric shock, use indoors only.

• Electrical motors can cause explosions when operating near explosive materials or vapors.

Do not operate this machine near flammable materials such as solvents, thinners, fuels, grain
dust, etc.

• This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit.

Voltages below 105 volts AC or above 125 volts AC could cause serious damage to the
motor.

ELECTRICAL - 115 Volt

This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. Voltages
below 105 volts AC or above 125 volts AC could cause serious damage to the motor.

ELECTRICAL - 240 Volt

This machine is designed to operate on a standard 16 amp. type L fused 230 volt, 50 hz, AC circuit.
Voltages below 200 volts AC or above 250 volts AC could cause serious damage to the motor.
I.E.C. Class 1.

GROUNDING INSTRUCTIONS

To protect the operator from electrical shock, this machine must be grounded while in use. This
machine is equipped with an approved three-conductor power cord and grounding type plug to fit
the proper grounding type receptacle.

This machine is for use on a nominal 120-volt circuit and has a grounding plug that looks like the plug
illustrated in sketch A. Make sure that the machine is connected to an outlet having the same
configuration as the plug. No adapter should be used with this machine.

For equipment rated 150-250 volts: If the machine is provided with an attachment plug as shown in
sketch below, it is intended for use on a 240 volt (nominal circuit.) No adapter is available for this
plug.

EXTENSION CORDS

Replace damaged or worn cords immediately. The table shows the correct size to use, depending
on cord length and nameplate amperage rating of machine. If in doubt, use the next heavier gauge.
An undersized cord will cause a drop in line voltage, resulting in loss of power and over-heating.
NOTE: the smaller the gauge number, the heavier the cord.

MAINTENANCE AND OPERATION INSTRUCTIONS

FOR AV-747-A VACUUM CLEANER

Though the AV-747-A is designed primarily for use on carpet, it performs very well on hard surface
floors. Sand, dust, paper, and so forth are readily vacuumed from these floors. However, it is not
recommended that this machine be used to vacuum metal slugs, metal shavings or similar type
debris from floors, either carpeted or otherwise.

Inspect the AV-747-A carton for shipping damage when received. Report any damage to delivering
freight carrier immediately.

OPERATING

a) Be sure the unit is used only on the voltage shown on nameplate.
b) When starting the AV-747-A, push down slightly and momentarily on the handle. Doing this

insures quick, easy starts, even when long pile carpets are being vacuumed.

c) In general, carpets with short naps - such as indoor/outdoor carpeting - are best vacuumed

with a setting of low, 2, or 3. Higher pile carpets are best cleaned with settings above 2. To
adjust brush height, disengage the cam lever (on right side) from the machine base and
position it in desired position. This handle is made to lock loosely in the positioning holes in
the base.

d) The rate at which an operator pushes the machine depends on the debris load, carpet nap

length, and type of debris. In areas where large amounts of “tracked in” sand are present,
carpets should be vacuumed with a double pass - that is a forward and backward pass made
without turning the machine around at the end of one pass. A slow, moderate walk pace by an
operator, normally suffices to give good cleaning results.

e) The filter bag should be kept clean. When it contains 15-20 pounds of normal debris, it is

ready for cleaning. To clean, release bag clamp and remove from machine and empty.

f) When storing, the handle may be folded over the cover. Two screws with wing nuts need to be

removed from the handle assembly when it is put in this folded position.

3

MAINTENANCE

a) Keep filter bag clean.
b) A drop of number 30 oil should be applied to the caster bearings and main wheel axles, two or so

times a year.

c) To replace brush, remove brush drive belt from motor pulley by rotating motor shaft by hand and

pulling outwardly on belt. Then, tip machine over on its top or side (hold motor mount assembly in
position when tipping or turning over); remove the sheet metal guard covering the brush pulley.
Use two small wrenches to simultaneously remove brush axle screws on each side of frame, and
slip brush out of brush cavity. Remove screws, axle, pulley and bearing end caps from brush.

NOTE: Inspect and replace the brush bearing, if necessary, at the time of reassembly. When re­mounting end caps be sure to press them squarely into the machined brush ends. Note: Be sure to
line up holes in caps and brush before pushing caps all the way into the brush core. After caps are
lined up and pressed in squarely, tighten cap screws securely. All parts can now be reassembled.
Turn both axle screws in brush axle at the same time for ease of installation. Also, be sure brush belt
is on brush before putting brush in brush cavity. After brush axle screws are securely tightened, line
up belt on brush pulley and then work the other end of the belt for tightness - it should be snugly tight,
not taught. Adjust tightness, when necessary, by adjusting screw heights on front of motor mount
platform. Check for tightness on fan belt also. If this belt is too loose, move motor toward front of
machine by loosening motor mount screws and sliding motor on forward. Be sure motor is at right
angles (square) with belts, then tighten mount screws. Recheck tightness of brush belt - adjust
again, if necessary. Reassemble other parts and unit is ready for use.

d) When the filter bag is removed for cleaning (or replacement) be sure unit is disconnected from

power source. It is good policy to inspect the fan to see if it has become fouled with debris such
as string, wire and so forth.

e) Periodically inspect the brush to determine whether it has become fouled with string, wire or

similar debris.
