When the manual's instructions lead you astray, try this.

Difficulty: Moderate

Instructions

Things You'll Need:

• long #1 philips head screwdriver

1. 1 Lower handle of vacuum and flip over so that it lies flat on floor upside down.
   2. Twist 3 plastic securing latches with large flathead screwdriver or a coin.
   3. Remove black plastic roller brush assembly cover.
   
   At this point, you should see the motor shaft it wraps around (it's metal and as big around as a pencil, buried fairly deep in the now exposed well, you'll also see two white plastic wheels that are part of the roller brush. One is an "idle" wheel that spins freely, and the other wheel is part of the roller brush and turning it turns the roller brush.
   
   4. Remove the roller brush assembly by pulling upward on it. You may need to "walk" the brush assembly out one end at a time a little bit at a time.
   5. Loop the new belt over the two wheels of the roller brush assembly and replace it back into the vacuum.
   6. If you can manage it, stretch the belt over the end of the motor shaft, making sure the belt is running between the two prongs of the belt guide operating by the carpet/bare floors switch.

2. If successful, perform steps 1-5 in reverse order to reassemble the vacuum. If you cannot stretch it over the motor shaft, you'll have to continue with step 7 to get a better grip and angle on the belt.

3. 7. Remove two screws next to rear wheels nested deep in screw socket holes.
   8. Remove 2 screws at front of corners of vacuum previously hidden by roller brush assembly cover.
   9. Remove 2 screws sunk in hole sockets next to flat holes that accommodate the coin screw latches.
   10. Remove 1 short screw from slightly behind roller brush in center of top assembly. (It is easily visible and you need not remove the brush assembly again to get it out with a screwdriver.)
   11. Remove the 2 screws holding down the metal brackets (1 screw per bracket) that hold down the carpet adjustment wheel assembly.
   12. Remove the brackets and the carpet adjustment wheel assembly.
   13. Remove carpet height adjustment lever by removing the single screw buried deep in the center of the plastic height adjustment cylinder. (a hollow cylinder with ratcheted teeth spiral gently down into the well.)
   14. Turn Vacuum right side up.
   15. Remove blue/green top assembly that fits over the start button and "Full" light indicator.
   16, Making sure belt is still looped over white plastic wheels of roller brush assembly, pull belt onto motor shaft.
   17. Replace top assembly, it snaps into place.
   18. Turn vacuum upside down and flat on floor.
   19. Make sure belt is running between prongs of guide operated by carpet / bare floors switch.
   
   Perform steps 1-13 in reverse order to reassemble vacuum.

Following these instructions does not guarantee success and and may result in breaking your vacuum, voiding the warranty, causing divorce, death and constipation. Rare side effects include ripping holes in the space time continuum. If the description of your relationship with the legal community is anything more positive than "tolerant suspicion", DO NOT USE THESE INSTRUCTIONS. I wrote them because I wanted to help the world at no cost to you, I'm not paying you jack squat if your dead vacuum is a little deader when you're done. Life isn't fair and it's not ALWAYS someone's fault. Cope and move on. There. Now that the whiners are gone... enjoy.
