If repair or replacement of the cord or plug is necessary, do
not connect the equipment-grounding conductor to a live
terminal. Check with a qualified electrician or service person
if the grounding instructions are not completely understood,
or if in doubt as to whether the vacuum is properly grounded.
Do not modify the plug connected to the vacuum – if it will
not fit the outlet, have a proper outlet installed by a qualified
electrician.
NOTE: for grounded, cord-connected vacuum rated less than
15a and intended for use on a nominal 120v supply circuit
The vacuum is for use on a nominal 120V circuit, and should be
connected to a grounding outlet that looks like that illustrated in
sketch A, FIG 3. A temporary adaptor, which looks like the adaptor
illustrated in sketch B, FIG 3, may be used to connect this plug to
a 2-pole receptacle as shown in sketch B if a properly grounded
outlet is not available. The temporary adaptor should be used only
until a properly grounded outlet can be installed by a qualified
electrician. The green colored rigid ear, lug, and 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 the metal screw.

NOTE: in canada, the use of a temporary adaptor is not
permitted by the canadian electrical code.
Ensure that the vacuum is connected to an outlet having the same
configuration as the plug.
Use of Extension Cords with Vacuum
Only use a grounded extension cord that is rated at least 12 amps
and has a third-wire ground. When a long extension cord is used
to connect the vacuum, a voltage drop occurs. The longer the
cord, the greater the voltage drop. This results in less voltage
being supplied to the vacuum and increases the amount of current
(amp) draw or reduces performance. A heavier cord with a larger
wire size will reduce the voltage drop. Be sure to choose a cord
that will supply enough voltage to operate the vacuum. The table
below indicates appropriate gauge for extension cords.
