Grounding Instructions
THIS PRODUCT IS FOR COMMERCIAL USE
ONLY.
Electrical
In the USA this machine operates on a standard 15
amp 115 volt A.C. power circuit. The amp, hertz, and
voltage are listed on the data label found on each
machine. Using voltages above or below those
indicated on the data label will cause serious damage
to the motors
Extension Cords
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
Grounding Instructions
This appliance must be grounded. If it should
malfunction or breakdown, grounding provides a path
of least resistance for electric current to reduce the
risk of electric shock. This appliance is equipped with
a cord having an equipment-grounding conductor
and grounding plug. The plug must be inserted into
an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
120 Volt Models:
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug illus-
trated in sketch A. A temporary adapter looks like
adapter illustrated in sketches B and C, may be used
to connect this plug to a 2-pole receptacle as shown
in sketch B if a properly grounded outlet is not avail-
able. The temporary adapter should be used only
until a properly grounded outlet (sketch A) can be
installed by a qualified electrician. The green colored
rigid ear, lug or the like extending from the adapter
must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adapter is used, it must be held in place by a metal
screw.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. Check with a qualified electrician
or service person if you are in doubt as to
whether the outlet is properly grounded. Do not
modify the plug provided with the appliance - if it
will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Une connexion non conforme du conducteur de
mise à la terre de l'appareil peut provoquer une
dé charge électrique. Consulter un électricien
qualifié ou une personne du service aprés vente
si vous suspectez que la prise de courant n'est
pas correctement mise à la terre. Ne pas modifier
la fiche fournie avec l'appareil - si elle ne rentre
pas dans la prise, faites installer une prise
apprropriée par un électricien qualifié.

Technical Specifications
Special Notes:
The sound pressure level at the operator's ear was measured to be 74dBA . This was a nearfield, broadband
measurement taken on a carpeted floor. This appliance contains no possible source of impact noise. The
instantaneous sound pressure level is below 63 Pa. The weighted root mean square acceleration at the
operator's arms was measured to be below 2.5m/s2. This was a tri-axial, third-octave-band measurement made
during normal operation on a composite tile floor. The measurement and related calculations were made in
accordance with ANSI S3.34-1986.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.

How this Machine Operates
This machine is a portable, easy to use wide area
vacuum designed for use indoors, in a commercial or
light industrial environment.
When operating as a carpet vacuum, soil is lifted from
the carpet surface by two counter-rotating brushes
and carried into a removable bag by the vacuum
motors.
1. Large debris such as paper cups, plates, string,
etc., should be picked up before starting the
cleaning process.
2. Plan your cleaning route to work away from the
electrical source. Move machine forward at a
steady pace.
Cleaning
1. Adjust handle to comfortable position at waist
level or higher.
2. Use your finger to depress the Vacuum switch on
the control panel to activate the vacuum.
3. When using optional accessory tool, brushes will
be deactivated when accessory port is lifted.
Keep machine moving while brush engaged.
Damage to carpet could occur if not moving.
Gardez la machine en mouvement lorsque la
brosse est engagée. Sinon, des dommages
peuvent se produire au tapis.
4. Move forward or backwards at a steady pace for
thorough cleaning. Run machine more slowly
over extremely soiled areas.
5. Use the right side of the machine for edge
cleaning.
6. To keep the vacuum operating at maximum effi-
ciency, check the filter bag regularly. Use the
upper and lower access holes in basket to feel
level of fullness. Empty when 1/2 to 3/4 full.
7. When finished vacuuming, coil the cord by
wrapping around the three cord hooks provided
on the handle tubes and control panel. The upper
hook pivots for easy release of the cord.

rations ou des ajustements de la machine.
Brush Deck
The dual cylindrical brush deck is designed to effi-
ciently extract dirt from the carpet. Please note the
differences between the front/rear brushes. Installing
them in reverse position will significantly reduce the
performance of the machine. The brush part numbers
are marked on drive ends of the brush core as
follows:
8.621-612.0 - Front Brush
8.621-611.0 - Rear Brush
Brushes should be replaced as a set when bristle
length wears to height of yellow PerformAlertTM
bristles.
Brush Removal
The brushes are removed from the right side of the
machine.
1. Adjust handle into the vertical position and lock
the cam lever. Tilt machine on it's back using
handle to support it's position.
2. Pull out on the bottom of the retaining clip.
3. The brush assembly and end cap should drop
down. Then pull the brush down far enough to
clear the bottom of the housing.
4. Pull brush out with a rocking motion to free brush
from drive hub.
Bearing Cleaning
1. Remove bearing cap from end of brush.
2. Clean cap and bearings.
Brush Replacement
1. Make sure the brushes are in the correct position
(front/rear) by following the brush installation
label on the underside of the machine. Lift the
drive side of the brush and push it onto drive hub
until a positive stop is felt. The brush cannot be
installed until the brush is fully seated on the
drive hub.
2. Pull out on the bottom of the retaining clip.
3. Line up end cap with the flats to each side.
4. Slide brush up into retaining clip until it clicks in
place.

Maintenance
Belt Replacement
The primary drive belt and secondary belt should be
replaced if they are damaged or broken. To
determine if a belt is damaged or broken, there will
be a noticeable drop in the performance of the
machine or the brushes will not spin when the
machine is turned on.
Primary Drive Belt Replacement
The primary drive belt is removed from the under side
of the machine.
1. Unplug power cord.
2. Adjust handle into vertical position and lock cam
lever. Tilt machine on it's back using handle to
support it's position.
3. Remove belt guard by loosening the (2)
mounting screws.
4. Remove brush motor assembly by loosening the
(4) mounting bolts.
5. Remove damaged or broken belt from drive
pulleys and replace with a new drive belt. Be
sure the grooves in the drive belt match the
grooves in the drive pulleys.
6. Install brush motor assembly with new drive belt
to the machine by using the (4) mounting bolts.
With mounting bolts in place but not fully tight-
ened, use weight of the brush motor assembly to
apply proper tension to the drive belt. Once the
belt is properly tensioned, fully tighten the
mounting bolts.
7. Attach belt guard to the frame by using the (2)
mounting screws.
8. Plug machine into a power supply and turn it on

Vacuum Motor Carbon Brushes
Replacement
If armature commutator is grooved, extremely pitted
or not concentric, the motor will need to be replaced
or sent to a qualified service center.
Important:
These brushes wear quicker as the length shortens
due to increased heat. Spring inside brush housing
will damage motor if brushes are allowed to wear
away completely.
Periodically check the length of the carbon brushes.
Replace both carbon brushes when either is less
than 3/8" (9.5mm) long.
