Grounding Instructions
This appliance must be grounded. If it should
malfunction or break down, grounding providesa 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 ordi-
nances.
120 Volt Models
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
indoubtas to whether the outletis properlygrounded.
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.

Vacuum Motor Carbon Brushes
Carbon
Brushes
End Cap
If armature commutator is grooved, extremely pitted or not
concentric, the motor will need to be replaced or sent to a
qualified service center.
Important:
These brushes wear quicker as the length shortens due to
increased heat. Spring inside brush housing will damage
motor if brushes are allowed to wear away completely.
Periodically check the length of the carbon brushes. Replace
both carbon brushes when either is less tan 3/8" (9.5mm)
long.
