To convert Kirby vacuum to Hand-Portable you have to replace long upright handle to a small one (included in the standard attachment set). Detach the bag and cord from the upright handle. Press the button under protective vinyl boot on the back near the vacuum cleaner motor unit
Pull the handle straight up - it should come out VERY easily.
Push the portable handle in. It also should go in very easily and just click in place.
Put the bag latch in the back of the handle
You are DONE and ready to use it as hand portable. It is great for vacuuming stairs, minivans, and mattresses. Keep in mind that brush roll will shake mattresses pretty well and if you suspect that the mattress may not withstand harder beating (old or very delicate mattresses) - do not vacuum it.
Make sure you clean wheels and bottom of the Kirby vacuum as it may be dirty from vacuuming carpets.
There are companies that specialize in sanitizing mattresses and we know several of those companies that use Kirby vacuums for this very purpose.
Make sure you have tech drive on OFF when using it as hand portable.
Once you install the safety cup it is a good idea to check if the vacuum is working. If it is not (assuming it did work with the nozzle) - check if safety cup switch actuator isn't broken (see picture).
If it works then but it does not when you install the hose (next step) you will know that you did not turn the hose far enough.
Take the bag off the Kirby. On the bigger end of the hose there is a line that you have to match with a little bump on the kirby fan housing (marked with red dots). Push the end of the hose over the Kirby exhaust as far as it can go.
Turn this hose end clockwise (you may have to apply considerable force).
It has to be turned far enough to press another safety switch that is on the unit just behind the exhaust neck.
You are done and ready to use it as a blower. We would recommend turning it on outside. Hose may have some dust accumulated on the inside and it may blow a lot of dust in the first few seconds of use. Also shake the hose well while outside to loosen any dust/dirt accumulations on the inside.
Be very careful when blowing dust out of computers or other electronics.
Dirt from inside of the hose may damage components.
Airflow is so strong that it may break circuit boards if they are not well mounted around the perimeter.
Using Kirby a lot of static electricity may be generated that may cause circuit failure due to electrostatic discharge (harmless to people - deadly to electronics).
NEVER operate blower with the nozzle on. There are 3 important reasons for that:
Kirby is designed to have much higher RPM (Revolutions Per Minute) with the hose or safety cup so it will push more air than with the nozzle.
If you use kirby as a blower with the nozzle - dust and dirt that is in the nozzle from vacuuming carpets and/or rugs will be blown into the air.
If there is nothing (no nozzle no safety cup) Kirby vacuum simply will not turn on.
