Slow speed sounds

STOP!!!!! Chris do not take out the brushes yet!!!! The problem could be the machine timing is off, and that requires a flat head and Philips head screw driver and a bit of patience. You will need to remove the back round cover and adjust one two or three screws that you will see in a triangle pattern (upside down pattern) the top right will be the place to start. The Phillips screw driver is used to loosen the screw that holds the rear round cover on, take the little screw all the way out . now grab the rear cover on the sides and while pulling back AND UP at the same time the cover will come off, it should not take a great deal of pressure to remove it , if you pull straight back you will break off two little clips on the inside bottom of the cover so remember that while you are pulling back to also pull up and maybe some gentle wiggling to remove the cover. Now you will see a very dusty dirty inside of the mixer , if it has never been cleaned before , no matter if you have a can of air (used for computers) you can use it to blow off some of the flour dust , you wil also see a Black and Copper plate with three screws in it, two at top and one at bottom center, the one at the top right is where you will start. These instructions are for very carefull directions, the three screws are the timing mechanism used by Hobart and Whirlpool to set the proper timing on the K5SS and going crazy will or could render the mixer inoperable so a little goes a long way, also you are now in the electrical contact area of the mixer and touching parts with a screwdriver can short out the speed control plate the motor or EVEN GIVE YOU A SUBSTANTIAL SHOCK, so proceed at your own risk, with that said lots of people have done this and have had no ill effects on body or machine , turn the machine on and turn the top right screw a little 1,8th turn either right or left the sound of the sputtering should increase or decrease if it increases turn it back to the original position and then back the other way an 1/8th turn, When I said you need to be patient it is becase the adjustments are made by ear unless you have some timing equipment the KA techs use. So be patient. Now if the sputtering does not stop or increase or decrease then return the top right screw to it's original position and move to the left screw and try that one, I assure you that you will notice a decernable differance in the sputtering from either one or both screws. Do not move the bottom screw as it is the adjuster for high speeds above six, Get back to me if this does not correct the problem, the brushes are not the problem here but cleaning them is not a bad idea as the K5SS was made between 1978 and 1986 if it is a Hobart and between 1986 and 2002 if it is a Whirlpool so cleaning them wouldn't hurt but as stated below the brushes must go back in a specific way or your machine will not work at all, There are four ways to insert the brushes and only one way will work.
