READ & FOLLOW ALL

INSTRUCTIONS, WARNINGS &

CAUTIONS

PLEASE READ CAREFULLY BEFORE OPERATING

This vacuum will afford you many years of trouble­free operating satisfaction, provided it is given
proper care. All parts have passed rigid quality con­trol standards prior to their being assembled to
produce the finished product. Prior to packaging,
your vacuum was again inspected for assurance of
flawless assembly.

This vacuum is protectively packed to prevent dam­age in shipment. We recommend that upon deliv­ery, unpack the vacuum and inspect it for any pos­sible damage. Only a visual examination will reveal
damage that may have occurred.

If damage is discovered, immediately notify the
transportation company that delivered your vacu­um. As a shipper, we are unable to report any claim
for damage. You must originate any claim within 5
days.

This manual is for your protection and information.
PLEASE READ CAREFULLY since failure to follow
precautions could result in discomfort or injury.
Read this manual completely before operating this
vacuum. It is important to follow the instructions in
the manual to prevent the possibility of injury or
damage to the user and/or vacuum.

Treat your vacuum cleaner as you would any other
high grade precision made product. Dropping,
unreasonable bumping across thresholds and other
misuses may result in a damaged unit that will not
be covered by warranty.

When using this vacuum basic precautions should always

be followed, including the following:

1) DO NOT leave the vacuum when plugged in.

Unplug from the outlet when not in use and before
servicing.

2) To avoid electric shock, DO NOT expose to rain.
Store indoors. DO NOT use on wet surfaces.

3) This is NOT a toy. Close attention is necessary
when used around or near children.

4) Use only as described in this safety manual. Use

because it has been dropped, damaged, left out­doors or dropped into water, contact an authorized
service center or factory.

6) DO NOT unplug the vacuum by pulling on the
cord. To unplug, grasp the plug, not the cord.

7) DO NOT pull or carry by the cord, use cord as a
handle, close a door on cord, or pull cord around
sharp edges and corners. DO NOT run vacuum over
cord. Keep cord away from heated surfaces.

8) DO NOT handle the vacuum’s plug with wet

GROUNDING INSTRUCTIONS

Improper use of the grounding plug can result in a risk of electric shock.

DANGER:

Electrical equipment must be grounded. If it
should malfunction or breakdown, grounding pro­vides a path of least resistance for electrical cur­rent to reduce the risk of electric shock. This vac­uum is equipped with a cord having an equipment­grounding 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.

GROUNDING METHOD

This electric equipment is for use on a nominal 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 recep­tacle as shown in (Fig B) if a properly grounded out­let is not available.

If repair or replacement of the cord or plug is nec­essary, DO NOT connect the grounded wire to
either flat blade terminal. The wire with insula­tion having an outer surface that is green with or
without yellow stripes is the grounding wire.

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 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. (Fig C)

WARNING:

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.
