How do i fine a scewdiver to fix my margaritavill, its has a scew in the bottem, that i have not seen befor..how i need to take the bottem off?

Sounds like your switch is going bad if it's an older machine that would be my guess and I usually guess right

Keep turning it counter clockwise, that's the way to raise the head.

Get a round file and gently rasp it out, you are trying to remove the build up in the hole not rasp the metal away. Flour dust gets in the hole and embeds itself into the soft metal of the dough hook. Also clean the shaft if you can see any dark patches on it. The shaft is good quality steel so you can use fine sandpaper on it without really removing any metal. It's not uncommon for a paddle or a hook to become frozen onto the shaft from flour dust getting in there while mixing. The first time I encountered it I had trouble convincing myself the flour was the problem, I've seen enough of them now to know that's what it is.

What model number is your machine? Try turning it on it's side and shake a little, take a very small screwdriver and grind away to crack the brush and shake it out. Otherwise it is a full tear down to take the brush holder out. Hope this helps if not get back to us for help

I read thru the owners manual for this unit and there is no recommendations for internal service. no reference to lubrication except for keeping the outside free from flour caking up on the moving parts. I have one of these and have seen the inside, they are built like tanks, you should be fine. i would recommend letting it run for a while on low speed to speed the lube around the internal parts, nothing more should be needed. Just make sure it doesnt sound as if the motor is laboring on low speed, this would indicate that internal lube is necessary. I think it will be fine...Worm1855

It seems that the mixer is overheating and tripping the thermostat thus preventing further use. I would recommend a thorough overhaul. You will need to carefully inspect all the components, particularly Items the brush assemblies, and the commutator portion of the armature (where the brushes touch the armature), and everywhere else in the motor compartment. Any parts exposed to oil will need to be degreased and dried before reassembly. When you reassemble your mixer, the brushes can only be installed one way. Make sure the brush's concave contact face is resting completely on the armature. If it is turned it 90 degrees too much, it wont' seat properly and the motor will not get any juice.
While your mixer's apart you should check for any other unseemly wear and tear on the gears, etc. You may find more things that need fixing, adjustment or replacement.You may find it easier to replace the brushes than degreasing them. I recommend using a food-grade grease that you can order online (although I've seen automotive bearing grease used too - your call). If you feel this is beyond your capabilities and will be too difficult to do by yourself you can take your mixer to a local small appliance repair shop and have them troubleshoot and fix your mixer.

You could always buy her a new model and have it painted Martha Stewart Green before you present it to her. To fix the old one you need to identify which parts are slipping and require replacement before we can help you out with a repair solution. It may be gears, it may be driving pins, it may be bushes or bearings or housings or a combination of all of them.

Adjust scew inside back of the mixer.

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.

If you remove the bowl guard you will see a magnet that attaches on iy in a white housing.The scews come loose and prevent it from closing the switch.Also the switch which comes out of the top pedestal can be adjusted.Let me know.
