If your mixer is running too fast on the slowest speed setting and throwing flour out of the bowl then you need to adjust the minimum speed. This may be achieved as follows.
The motor tends to speed up over time and needs adjusting back down to 60rpm at the slowest speed control setting on the side.
Qué necesitas
-
-
Turn the power off at the wall socket and then invert the machine on a working surface allowing for flour and crumbs to fall out of the machine onto the surface.
-
-
-
Insert a long thin flat ended screwdriver (Health & Safety warning - with an insulated handle) through one of the slots in the plastic casing covering the motor assembly and locate one of the two slotted screws which govern the centrifugal switch.
-
Try a quarter turn clockwise each then turn the machine back over and try it on the slowest speed.
-
-
-
-
Put your hand on the mixing attachment holder and let your fingers gently catch the protruding bit each time it comes around while watching a second hand on a clock.
-
You are looking for about 60rpm and the movement at this minimum speed will be somewhat erratic.
-
There will also be a burning smell from the resistor but don't worry about this. The burning smell comes from flour deposited over time on the resistor.
-
-
-
If it still exceeds 60rpm on the slowest speed control setting then turn the machine over and turn the two screws in a bit more, but evenly on each side to keep the centrifugal switch bracket evenly balanced.
-
Continue until about 60rpm is achieved and ignore the burning smell from the thin layer of flour on the resistor.
Followed your clear instructions but still cannot slow speed down - any other ideas please?
Excellent simple instructions thank you for sharing your knowledge . It’s one of my wife’s favourite machines and she would be sad to lose it after so many years of faithful service

Great advice Thank you.
Purchased a 701a with original user manual, Liquidiser, Veg Shredder with all the shredding blades, Juicer and Mincer yesterday from a local Charity shop all for a measly £25.....Cleaned it all and adjusted the speed as per above, all to a very good used condition. Bargain of the year.
I recently bought an A701a. When mixing dough on setting two, it violently moves around on the bench. Is this normal?
Don’t mix on speed 2 - it’s too fast. You are trying to stretch the dough, not tear it. It may be that your dough is too dry and solid so that it won’t give when the dough hook tries to stretch it. I am assuming that you do have a dough hook and are not trying to mix dough with the K beater. If not - get one - solve your problem at a stroke. Happy Baking!
Also worked for my A902 which I replaced the capacitors on but could not see how moving the control board up and down on the sprung screws could adjust the speed or how to set it. Well I still can’t see how that up/down adjustment works but it does! Thanks very much!
In reply to Matthew Tribble by Paul Bird (the OP)
My understanding of the A701 is as follows. The rotating contacts form a centrifugal switch and the faster it rotates the flatter the assembly, i.e. it is spring loaded to make contact but on rotation flattens out to disconnect and break the circuit. Hence by undoing the two screws you are moving the contact point further from the assembly allowing it to disconnect sooner.
Perhaps the A902 has a different circuit I really don’t know. I only know the principle of operation and how to adjust it.
Got it down to 68 before it was really cronky. Cheers thanks for that. I had soldered a new set of components a couple of years back and was upset that it was going so much faster. It was fringing stuff out of the liquidiser! Now it runs sweet! Thanks,
I have done this till screws were right in but mixer still to fast, what next?
I messed up and adjusted one screw more than the other. I tried to guesstimate and balance it but obviously it won’t be as accurate. Is there a way to balance it again? It’s currently set at 60RPM but makes an occasional clicking noise ~ every 2 rotations near the motor (though it is pretty old and lots of things are ‘near the motor’). It’s not smoking or sparking. I know i was careless with the screws. I messed up.
I own a KM230. I have changed the 150nf and 100nf capacitors as well as the 56-ohm resistor. The motor runs at the max speed all the time now. I tried screwing the 2 screws clockwise but it doesn’t help. I screwed it in so much that a power cable was damaged by the motor. I might be connecting the ground wire to the wrong screw. I have no idea which screw the grounding wire should be connected to. Any ideas?
I don't know this device, maybe the adjustment is similar to the 901, described here. Look for step 11, second picture. Make sure that the pin on the support of the circuit board is engaged in the guide rail on the knob (marked by the red rectangle in the second picture). If you turn the knob, the circuit board needs to be able to move up and down a bit, otherwise the machine will not work! Learn in step 12 how to adjust the speed.

I love you whoever you are! Problem sorted with the turn of a screw. Your advice is very much appreciated, thank you so much.
60rpm seems too fast as a minimum speed. When I set my kenwood A901 up like that it hit the max speed at around 4-5 on the dial.
I found 30rpm much better, when set to the slower minimum I had a smooth progression across the entire 1-8 range of the speed dial.
Well, it´s what Kenwood says in the A701 Service Manual, on page six. 60 RpM +/- 5 RpM. I think the A901 needs the same frequency. But it´s no problem, if it is good for your machine.

Hello
I have just replaced my planet gear as the nylon one snapped ( too much dough, not enough water!). Thought the machine runs faster than 60rpm as well. Looking at this site your solution sounds just right but I cannot seeem to locate the screws. Is the entry point through the casing in between the bowl area and gear hub area or do you turn the mixer completely upside down?
Or alternatively, is there any chance you can post a photo?
Read this guide, especially the last steps:

Can someone pls help me out aswell. Hv the same problem and even after reading what to do I don’t know where to start. Can someone pls upload a video for better idea
Later models have posidrive machine screws
