If you have a multi meter check the box caps and resistors for KM 2XX series then replace it whenever required. Some may differ in values like 0.15uF 275x2, 0.33uF 275X2 or 0.47uF 275X2 then resistors may also differ with different models but common to have 1.1k ohms 2watts. Also if caps are open it is good to check the 600V triac and replace it when giving out lower output. I also advise to clean the commutator esp when is is sparking a lot, you may use light sanding and clean it after. Check also if the tachometer is good, there is a resistor-like-coil hidden under a plastic tab with 2 wires. This gives feedback and via a magnet attached to the shaft. Check the motor brush if it is good or worn out. Lastly check all the switches because if one of them is not working properly you wont be able to let the motor run.

A white or clear lithium grease. Do not cake it on but enough to get into all of the cogs/worm gears.

I use white food safe grease. Here is an example; https://www.ebay.co.uk/itm/391996333570?epid=25018211366&hash=item5b44cd5e02:g:NlUAAOSwoeVdxAPv

it possibly stripped the coupler

We are FIXYA dot com, we aren't Kenwood Chef, we aren't who you think we are. There can be two reasons for a Kenwood Chef to run but not turn the beaters. The most likely one is that the Drive belt has broken. Or You have strained the beaters and you have sheared the shear pin in the drive shaft. It is there to save you damaging the motor and gearbox.

Hi, I can help you also and send you a complete pdf file of the original service manual. Please send me your email.

Sounds to be dirty. There is a thing called tuner cleaner you can use to clean it. You will need to remove the control knob and try spraying into the control,but you may have to get inside to clean it up good by breaking down the unit.

Kitchen Aid suggests putting a dime in the bowl and turning the mixer on low. If the beater attachment pushes the dime around the bowl, the attachment is too low. If dime doesn't move, the attachment height is too high. When the attachment height is just right, the dime will only move a little.

there is one here...http://web.archive.org/web/200707171...tions-A701.pdfbut the pages are in the wrong order and i think some are missing.

Need to take a 2x4 balance it between the outlet for the grass and maybe a pair of vise scrips and then try to take it off.

Sounds as if the amplifier is overheating? Does it do this at all volume levels or only when turned up to higher levels- if so it's likely the amplifier inside of the receiver.

Any idea how many operational hours? I suspect motor brushes but can be other.

sounds like the brushes need replacing see link for them https://www.partmaster.co.uk/chef-food-mixers/chef-range/km001/catalogue.pl?shop=kenwood&path=590704,71679&model_ref=440446&page=3

If you do not know what you are doing it is better to throw it away and get a new one. You could get electrocuted if you try yourself. Probably cost more than a new one to get someone to repair it.

Possible similar model manual for sale on Ebay, but I cannot be certain that is a service manual for yours.
