Hoover WindTunnelTM manual Lubrication, Hoover Cleaning Performance, Thermal protector

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).

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.
