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

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.
