My kitchenaid ksm150 has problems with the speed. how do i fine tune the speed. At 1 its as fast at 4 or 6 now. I noticed 3 screws at the back. What is the default setting

SOURCE: Kitchenaid K5A mixer 10 speed only runs on fast, no slow speed

Pull the back off and there will be two screws at the top of the Speed Control Plate and a 3rd screw at the bottom. Tighten the top two screws down. [email protected]. Let me know if it works.

You can try adjusting the speed control as shown in section 6 of the service manual:

Also remove and clean the brushes as shown in the same manual pg 8 fig. #30.

You are not adjusting the screws correctly. All three screws (2 top left and right, and 1 bottom)
must all be adjusted. Here is how:

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:

Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280
