Question about Vacuums
Will other D4 water bowls fit a D4A and where can I get an instruction book
Yes, but just the D4 variety, not D2,D3, or E
The main thing to remember about this great vacuum you have is to always dry out the bowl or at the very least keep the bowl separate from the vacuum (top). The D4 motor was and still is the biggest and best motor EVER put in a vacuum, but if you let the moisture sit on this motor by not drying the bowl then what will happen is the spring loaded carbon brushes that make contact with the motors armature will ever so slightly 'stick to the armature. Then when you go to turn the vacuum on the motor will not even have the needed chance to begin it's rotation.Electricity in a motor has to move it's counterparts or it will instantly short circuit. Now believe it or not, as powerful as this motor is, if it can't move it will short. Ironically, you can do one thing ritualistically each and every time you use you Rainbow so that what I just described will never happen:
Under the top part f the vacuum you will see a pot pie shaped thing with a nut in the center. This is the heart of the Rainbow and it is called the separator. Very simply grab it and give it a spin. That's it! Now you have done the one and only thing to be sure the motor is not going to stick. Yep it was that simple, but if I didn't explain it's importance you would never know why they quit making this great vacuum and instead make the latest and supposedly greatest 'brushless' model E2. Stupid in my opinion. All they had to do was put a message on the top somewhere saying, " Before operating, unplug 110V plug, flip top and spin separator by hand to be sure it is free"
