The tilt part of my mixer moves when mixing, more so as the speed increases. Is this normal? At first I thought it was because the beater was hitting the bottom of the bowl, but I have corrected for this and it still happens. I just want to know if this is supposed to happen.

Make sure your Beater can slip in and out of the Beater Shaft
easily. Do not force the beater onto the Shaft if the shaft is bent.
If it cannot be removed easily by hand, use a soft rubber mallet
(not a steel hammer) to slightly tap the beater so it can be moved
up and down the shaft or from side to side. Then you can easily
turn the beater left and remove it from the shaft.

From Kitchenaid Manual:
To Attach Flat Beater, Wire Whip, or Dough Hook
1. Turn speed control to OFF.
2. Unplug stand mixer or disconnect power.
3. Tilt motor head back.
4. Slip beater onto beater shaft and press upward
as far as possible.
5. Turn beater to right, hooking beater over pin on shaft.
6. Plug into a grounded 3 prong outlet.

I am sure you are locking the tilt head in the down position when your using it right? If so then check to see if the beaters are hitting the bottom of the bowl. If they are then there is an adustment screw that sets the height of the head in the down position.

If that is the bowl that came with the machine it is not wrong. What happens from time to time is that the head on the mixer automatically adjusts causing the beater to not operate as it should. To adjust the head on the mixer place a dime at the bottom of the bowl, attatch the beater to the mixer and make as if you are going to start mixing. The beater should JUST touch the dime. If it doesn't touch it at all or is pressing it against the bowl, tilt the head of the mixer up to locate the adjustment screw located inside the shaft. Take a flat head screw driver, turn the screw clockwise (to lower the head) or counter clockwise (to raise the head). Place the beater back on the mixer, turn the machine on and see if it moves the dime moves. Once it is properly adjusted the dime should move ever so slightly.

JOE:You don’t say if you have a ‘tilt-head’or a ‘bowl-lift' mixer, but you can easily download a PDF version of your Owners Manual from the KA website (http://www.kitchenaid.com/flash.cmd?/#/page/home).Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number (in your case, use KSM90P)and select the last file listed that appear under Owners Manuals:KSM90PSWW0.pdf (2930.74 KB)and save that file to your PC.You’ll need to have Adobe Reader to be able to open it. Turn to Page 11 and you will find the instructions for adjusting the mixer head height.I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beaterjust clears the bottom of the bowl. If for any reason, the flat beater hits thebottom of the bowl or is too far away from the bowl, clearance

Tilt-Head models
• Unplug mixer.
• Lift motor head.

• Turn screw (A) SLIGHTLY counter clockwise (left) to raise flat beater or clockwise (right) to lower flat beater.
• Make adjustment with flat beater, so it just clears surface of bowl.
If you over adjust the screw, the bowl lock lever may not lock into place.


Bowl-Lift models
• Unplug mixer.
• Place bowl lift handle in down position.

• Turn screw (B) SLIGHTLY counter clockwise (left) to raise flat beater and clockwise (right) to lower flat beater.
•Make adjustments with flat beater, so it just clears surface of bowl.

I hope this helps! –Howard, Burke, VA

Your beater to bowl clearance has come out of alignment. This can happen naturally over time and with normal use of the appliance. This is something you may correct from home using a flathead screwdriver.

Unplug the mixer, with the bowl and flat beater removed. Tilt the mixing head back as far as the machine will allow. In the exposed hinge, behind where the bowl would normally sit, you will see a 3/8 screw exposed. Turn this screw half a turn counterclockwise (to your left) in order to raise the flat beater from the bottom of the bowl.

This may take a few attempts until the beater is clearing the bottom of the bowl again. If the adjustment screw will no longer turn, do not force it. It is only designed to move so far to make the appropriate adjustment.

Be cautious. Raising the flat beater too high may leave dry ingredients at the bottom of the bowl.

If further information is needed, I would advise you to contact Kitchenaid Customer Service. They may walk through this adjustment through you over the phone and can look into ordering replacement beaters for you also.

Their toll-free telephone number is 1-800-541-6390.

The height of the beater is easy to adjust on the tilt-head model.  Tilt the head back, and look into the pivot from the front of the mixer.  You should see a screw on the hinge.  With a flat blade screwdriver, rotate this screw half a turn counter-clockwise to raise the beater height.  Lower the head and check that the beater does not touch the bowl.  Repeat until the adjustment is satisfactory.  To lower the beater closer to the bowl, turn the screw clockwise instead.

The "wobbling" sounds like an issue of beater to bowl adjustment, which can come out of alignment naturally over time and with use of the machine.

If the flat beater is striking the bottom of your bowl, this may cause the locking mechanism to loosen and may cause the mixing head to "bounce" during use.

Your Use and Care Guide will cover the "beater to bowl adjustment," which you can do at home in a few minutes with a flathead screwdriver.

Also, leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.
