Lubrication
The motor is equipped
with bearings
that contain sufficient lubrication for the
life of the motor, The addition of lubricant
could cause damage. Therefore,
do not
add lubricant to motor
bearings.
The agitator is equipped with two ball
bearings that should be lubricated
periodically
by a Hoover Factory
Service Center or an Authorized
Hoover
Warranty Service Dealer (Depot).
Therma|
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 dirt cup pre-filter, HEPA
cartridge filter and secondary and final
filters for dirt accumulation.
3. Refer to "Clearing blockages"
section.
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).
