Tune-up Checklist
Check the drive belt
Examine the condion of the Flat Corded Belt located in the base unit. Check for wear, fraying,
and for pits and cracks. To remove the belt, follow step 1 and steps 7-8 of the Base Unit secon.
Check the Brushroll Assembly
Spin the roller brush to determine that the turning moon is uid and smooth without noise or
binding. To remove the roller brush, follow step 1 and steps 7-10 of the Base Unit secon.
Check all electrical connecons
Use a voltmeter to check voltages in all circuits.
Clean the Brushroll Assembly
Clean the Brushroll Assembly of all lint, dirt, and hair, or anything that could restrict the turning
moon of the brush. To remove the Brushroll Assembly, follow step 1 and steps 7-10 of the Base
Unit secon.
Clean housing and Baseplate
Use a small brush and compressed air to clean the housing and the Baseplate. Thoroughly wipe
down the outside housing and the Baseplate. DO NOT use soap and water because the Baseplate
has all parts aached. Soap and water will damage the parts.
Clean Outer Bag and Bag Dock
Use a damp cloth to wipe down the Outer Bag. Open the Outer Bag and vacuum out any dust or
debris. Remove the inner, disposable bag and thoroughly wipe down the Bag Dock.
Replace any worn or damaged seals
Check the following seals within the unit for cracking, spling, or signicant wear and replace if
necessary:
• O-Ring (9) at base of Collar Dirt Tube (Follow disassembly instrucons steps 2-4 of the Han-
dle/Upper Assembly secon to check the dirt tube O-Ring.)
• Brush Chamber-to-Inlet Seal. (Follow disassembly instrucons steps 1-2 and 5-6 of the Base
Unit secon to remove the Inlet Duct.)
Replace the inner bag
1. Pull tab on bag to release Bag Dock from connector. Bag Dock door hinges downward.
2. Gently pull bag cardboard collar outward from Bag Dock.
3. Slide the cardboard collar of the new bag onto the Bag Dock door.
4. Firmly push Bag Dock door with both thumbs on the indicaon point unl it snaps.

Disassembly Instructions
Be certain to unplug the unit while servicing except when you need to test a parcular funcon. Numbers
below refer to the numbered parts in the Service Parts List.
Handle/Upper Assembly
NOTE: If no service is necessary for the upper assembly, skip to Base Unit section to disassemble the base unit.
1. Remove the Handle Assembly (40) from the upper assembly by depressing the spring plungers
found underneath each if the four rubber covers where the Handle Assembly (40) meets the Outer
Bag (26). *Note: Later producon units have only 2 springs mounted on opposite corners.
2. Use an Allen wrench or a small screwdriver to depress the spring plunger. As you depress the
plunger, pull up on the handle unl the plunger slides under the bracket slightly and stays in the
depressed posion. Do this with each plunger, then pull the handle up and away from the bag to
remove it completely.
