This scrubber will afford you many years of
trouble-free operating satisfaction, provid-
ed it is given proper care. All parts have
passed rigid quality control standards prior
to being assembled to produce the finished
product. Prior to packaging, the scrubber
was again inspected for assurance of flaw-
less assembly.
Your scrubber is protectively packed to
prevent damage in shipment. We recom-
mend that upon delivery, unpack your
scrubber and inspect it for any possible
damage. Only a visual examination will
reveal damage that may have occurred in
transit.
If damage is discovered, immediately notify
the transportation company that delivered
your scrubber. As a shipper, we are unable
to report any claim for damage. You must
originate any claim within 5 days of delivery.
The manufacturer takes no responsibility
for damages caused to property or per-
sons due to improper use of the scrubber.
Operating instructions must always be
available for the operator. The scrubber
may only be operated by persons who have
been fully trained and authorized to use it.

when plugged in. Unplug from outlet when
not in use and before servicing.
2) Turn OFF all controls before unplug-
ging.
3) This is NOT a toy. Close attention is
necessary when used around or near chil-
dren.

manual. Use only manufacturer's recom-
mended attachments and accessories.
5) DO NOT use electric scrubber with
damaged cord or plug. If the scrubber is
not working as it should, because it has
been dropped, damaged, left outdoors or
dropped into water, contact an authorized
service center or the factory.
6) DO NOT pull electric scrubber by the
cord, use cord as a handle, close a door
on cord or pull cord around sharp edges
and corners. DO NOT run scrubber over
cord. Keep the cord away from heated
surfaces.
7) DO NOT unplug the scrubber by pulling

surfaces that have dust or substances
which are flammable, poisonous, caustic,
or irritants and represents a health hazard.
13) DO NOT use where anesthetics or
oxygen are used.
14) DO NOT use an extension cord unless
absolutely necessary. If an extension cord
is used, then wire size must be #14 or
larger and should not exceed 50 feet in
length. The extension cord must be a
three-wire grounded type.
15) Replace damaged or worn parts

To Avoid Electric Shock, Do Not Expose To Rain
Store Indoors.
When using this equipment basic precautions should
always be followed, including the following:
WARNING:
This scrubber is designed to be safe when
used to per-form cleaning functions as
specified. Should damage occur to electri-
cal parts, the unit should NOT be used
until the damage is repaired by the manu-
facturer or an authorized service center.
This will avoid further damage to the
scrubber or injury to the user.
These instructions are for your protection
and information. PLEASE READ CARE-
FULLY! Failure to follow instructions or
precautions could result in injury or dam-
age to the user and/or the scrubber.
CARE OFTHE
SCRUBBER

Improper use of the grounding plug can result in a risk of electric shock.
GROUNDING
SAFETY
INSTRUCTIONS
Electrical equipment must be grounded. If
it should mal-function or breakdown,
grounding provides a path of least resist-
ance for electrical current to reduce the
risk of electric shock. The scrubber is
equipped with a cord having an equipment-
grounding conductor and grounding plug.
The plug must be inserted into an appropri-
ate outlet that is properly installed and
grounded in accordance with all local
codes and ordinances.
If repair or replacement of the cord or plug
is necessary, DO NOT connect the ground-
ed wire to either flat blade terminal. The
wire with insulation having an outer sur-
face that is green with or without yellow
stripes is the grounding wire.
GROUNDING
METHODS
This electric equipment is for use on a nom-
inal 120 volt circuit, and has a grounded
plug that looks like the plug illustrated in (Fig
A). A temporary adaptor that looks like the
adaptor illustrated in (Fig B & C) may be
used to connect this plug to a 2-pole recep-
tacle 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 color rigid ear, lug or the like extend-
ing 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 (Fig 3).
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 equipment. If it will not fit the outlet,
have a proper outlet installed by a qualified electrician.
Note: In Canada, the use of a temporary adaptor is not permitted
by the Canadian Electrical Code.
