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 peri-
odically by a Hoover Factory Service
Center or an Authorized Hoover Warranty
Service Dealer (Depot).
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).
