Hi Rob.
The main features of the Kirby are.
4 types of vacuum cleaners in one. (Upright, tank/canister, hand vac, and electric broom.) Floor polishher, carpet shampooer, buffer/polisher/knife sharpener. As well as a sprayer/demother.
As mentioned in my last post, all of these work off the suction, or exhaust ports. The parts include the main machine in upright mode, attachment kit with hose and wands, Miracle Head for polishing floors in upright mode, Rug Renovator (shampooer) also in upright mode. And tank/canister in hose mode with either upright handle, or lifter grip in place.
For use as a blower, moth proofer, sprayer (paint, wax, insecteside, or soapy water.) The Rug Renovator uses both ports. In addition is the Miracle head for floor polishing, and Handi-Butler with or without the flexible shaft is for sanding, drilling, polishing, knife sharpening and so on. On later Kirby models the Turbo tools were added to sand, buff, and yes, even cut hair!
As I don't know what, if any of these parts you have I can't elaborate. The Kirby looks like a monster, but the monster is quite tame if you learn to switch the parts. Also, in most cases, there are only 2 of these features needed. 1 upright mode and 2, tank/canister mode. A simple turn of the belt lifter, and locking lever are all you need.
Now, to keep the floor nozzle in top working order, change the belt as it most likely is stretched or worn. Get a new belt at any vacuum cleaner shop, or on Ebay, etc.. Here's what you do to replace it.
Remove the nozzle from the power plant, note that the belt is stretched on the special finger, rotate the belt lifter so it moves freely. Next, flip the nozzle, brush up, and pull the lower guard away by sliding you finger under a metal bar, and lift up. If it's tight, spray with WD-40, and the brushroll will be free. There are 2 tabs on eithe side of the brush roll with screws. Do NOT unscrew! pull one tab, and the brushroll will slide out. You do not need to remove the entire brushroll, only one side. Slide off the old belt, and put the new one in place. Slide the brushroll back and close the rug guard to the nozzle. Center the belt, and rotate the magic finger with the belt in the center, and turn again to stretch the belt. (Because the belt is new, it will be tight!) With the belt extended, attach the nozzle to the power plant, and rotate again to lower the belt to the drive shaft. I know it sounds complicated, but changing the belt takes aprox. 10 minutes, and won't need to be done often.
If you have the Miracle head, the brushroll be held with a screw philips on either side of the attachment. Again, remove one screw, slide off the bet and replace with the new one.
Setting the right hight of nozzle to carpet is done with the foot lever, with the numbers. This is called 'Toe-touch-control,' and lets you set the right hight. Start with the Kirby at the highest setting, turn on the motor, and one notch at a time, lower the nozzle by stepping on the number thingy. The motor should go from a strong woosh, to a gentle purr. This is called 'Tripple cushion vibration,' as it lifts the carpet, and vibrates the dirt free. The Kirby shouldn't be hard to push, if so, the lever is too low, raise it up a notch!
Basically, this is all you need to operate a Kirby. If you have any further questions, ask me.
