DANGER:
Improper use of the grounding plug can result in a
risk of electric shock.
GROUNDING
INSTRUCTIONS
Electrical equipment must be grounded. If
it should mal-function or breakdown,
grounding provides a path of least resistance for electrical current to reduce the
risk of electric shock. The vacuum 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
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.
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
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.
GROUNDING
METHODS
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 3).
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.
Treat this vacuum as you would any other
high grade precision made product.
Dropping, unreasonable bumping across
thresholds and other misuses may result
in a damaged unit which will not be covered by the warranty.
