Lubrication
The motor is equipped with bearings
that contain sufficient lubrication for the
life of the motor. The addition of lubri-
cant could cause damage. Therefore,
do not add lubricant to motor bear-
ings.
The agitator is equipped with two ball
bearings that should be lubricated peri-
odically by a Hoover Factory Service
Center or an Authorized Hoover
Warranty Service Dealer (Depot).
Hoover Cleaning
Performance
This Hoover Cleaning Performance
System is for comparing the relative pro-
gressive performance of Hoover
uprights only and not for comparison
with any other brands. The majority of
this rating is based upon the American
Society for Testing and Materials (ASTM)
Carpet Cleaning Effectiveness Testing
(ASTM Test F608). Other performance
factors include Hose Power (ASTM Test
F558), Surface Litter Cleaning, Hard
Floor Cleaning, Edge Cleaning, Air
Filtration and Cleaning Width.
Thermal protector
An internal thermal protector has been
designed into your cleaner to protect it
from overheating.
When the thermal protector activates,
the cleaner will stop running. If this
happens, proceed as follows:
1. Turn the cleaner OFF and discon -
nect it from the electrical outlet.
2. Check secondary and final filters
for dirt accumulation.
3. Refer to "Clearing blockages" sec-
tion.
4. When cleaner is unplugged and
the motor cools for 30 minutes, the
thermal protector automatically resets
and cleaning may continue.
If the thermal protector continues to
activate after following the above steps,
your cleaner may need servicing (see
"Service" section).

blockage in the system. Refer to the
following steps to check for blockages
continuing with each step until the
blockage is found:
