Clearing blockages
Disconnect cleaner from electri-
cal outlet.
Warning - Brush roll can start
suddenly. Unplug cleaner when it
is turned over.
Low suction or pick up may be due to a
blockage in the system. Refer to the
following steps to check for blockages
continuing with each step until the
blockage is found:
1. Check fullness of filter bag; change if
needed.
If a minor problem occurs, it usually can
be solved quite easily when the cause
is found by using the checklist below.
Checking airflow path
2. Plug cleaner in and turn ON. Check for
suction at end of hose (A).
a. If there is suction, continue with
step 3.
b. If there is no suction , check for
blockage in hose and dirt tube as
follows:
1) Disconnect hose from dirt duct (C)
by reversing procedure for “Attach
hose” on p. 4, Figs. 1-5 and 1-6.
2) Clear out hose.
3) Look into (C) and remove blockage.
3. Check connection at hose tube (B);
remove any blockage.

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).
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).
