Safety
Electrical:
In the USA, this machine operates on a standard 15
amp 115V, 60 Hz, 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 malfunc-
tion or break down, 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
ordinances.
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in "Fig.
A". A temporary adaptor that looks like the adaptor in
"Fig. C" may be used to connect this plug to a 2-pole
receptacle as shown in "Fig. B", if a properly grounded
outlet is not available. The temporary adaptor should
be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green
colored rigid ear, lug, or wire extending from the
adaptor must be connected to a permanent ground
such as a properly grounded outlet box cover.
Whenever the adaptor 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.
Le raccordement incorrect du conducteur de terre
d'équipement peut entraîner des risques d'électrocu-
tion. Vérifiez auprès d'un électricien qualifié ou d'un
responsable de l'entretien si vous avez quelque doute
que ce soit quant au raccordement à la terre de votre
prise murale. Ne modifiez pas la fiche fournie avec
l'appareil : si elle ne correspond pas à la prise murale,
faites installer une prise adéquate par un électricien
qualifié. Utilisez-le uniquement sur des réceptacles
protégés GFCI.

hold the switch in the "on" position with the thumb,
and is typically used in small areas where short
cleaning passes are made.
The continuous setting allows the operator to set
the switch in the "on" position with one touch, and
is typically used in large areas where long cleaning
passes are made.
Cleaning Procedure
