Lubrication
The cleaner is equipped with bearings
that contain sufficient lubrication for the
life of the cleaner. The addition of lubri-
cant could cause damage.
Therefore,
do not add lubricant to any bearings.
Thermal protector
An internal thermal protector has been
designed into your cleaner to protect it
from overheating.
When the thermal protector activates,
the suction motor will stop running,
however the agitators will continue to
run.
If this happens, proceed as follows:
1. Turn the cleaner OFF and discon-
nect it from the electrical outlet.
2. Check dirt cup pre-filter, HEPA
cartridge filter and final filter for dirt
accumulation.
3. Refer to “Clearing blockages”
section.
4. When the motor cools, 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).
Hoover Cleaning
Performance
This Hoover Cleaning Performance Sys-
tem 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 ASTM
International Carpet Cleaning Effective-
ness Test (ASTM Test F608). Other per-
formance factors include Hose Power
(ASTM Test F558), Surface Litter Clean-
ing, Hard Floor Cleaning, Edge Clean-
ing, Cleaning Width, and Air Filtration.

Problem: Dirt inside dirt cup stops
spinning
Note: Heavy debris may settle to the
bottom of the dirt cup and prevent the
dirt from spinning without affecting
cleaning performance. The cleaner can
continue to be used even if the dirt is not
spinning inside the dirt cup.
However, if the dirt does stop spinning
AND there is a noticeable decrease of
performance, check the items under
“Cleaner won’t pick up”.

roll won’t turn
Possible cause
Possible solution
• Too much pressure being applied to
