Clearing Clogs

Low suction or poor pickup may be due to a clog in the vacuum cleaner. If you notice a change in the sound of the motor or a reduction in the spinning action, check for clogs.

4.

Check the clear panel on the back of the Cylinder for a clog. If there

5. is an obstruction, remove the screws to remove the panel and clear this area.

Grasp the Hose Grip and lift to separate from the suction opening.

6. Check for a clog in the Base or the Hose.

If the clog persists, follow the instructions for Checking the Rotating

7. Brush on page 11 and inspect the Air Passageway for obstructions.

Thermal Protector

An internal thermal protector has been designed into your cleaner to protect it from overheating. When the thermal protector activates, the main vacuum motor will stop operating. If this happens, proceed as follows:

 

Turn the cleaner OFF (O) and unplug from electrical outlet.

1.

Check the Upper Tank area, Pre-Motor Filter and

2. Post-Motor Filter for dirt accumulation.

3. Refer to the "Clearing Clogs" section above.

When the motor cools for approximately 30 minutes, the

4. 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.

NOTE: The thermal protector controls the main vacuum motor only, not the brush motor. If the thermal protector activates, the brush will continue to operate normally; however, there will be no suction.
