Question about Makita 9553NB 4" Angle Grinder

1 Answer

Grinder only works when screws are loose on the head

My grinder stoped working. Tried to get inside to clean it up. Found that when I loosen the top screws and seperate the head from the body a little it works fine, but when I tighten the screws back it stops working. I cant seem to get inside to see what the problem is.

    How do I know if it's the bearing and where can I get parts? Thanks

    Thanks for your help. I think it's actually the carbon brush set. I've ordered new ones. I'll write back if that does'nt work.

I would suggest going to Makitatools.com and typing in your model number to look at a schematic. It could be numerous things that are wrong. I would think a bearing is going bad, but take a look and let me know and I will see what I can do.

    If this tool is in fact a Makita product I would go to Makitatools.com and look at a schematic. To find out if it a bearing if you are comfortable with the disassembly after looking at breakdown you can hold the bearing in one hand and spin the armature with the other it should roll freely. Also look for the outer race being loose.. Let me know if I can help further

How do I clean the inside of the coffee grinder kitchenaid model A-9


Instructions Things you need
  • Soapy water
  • Screwdriver
  • Burr cleaning brush
  • Damp cloth

1 Turn off your KitchenAid coffee grinder and unplug it from the socket.
This reduces the risk of injury while cleaning the appliance.

2 Turn the bean hopper, located at the top of the grinder, counter- clockwise and remove it from the appliance.

3 Slide the coffee bin toward you to remove it from the grinder.

4 Wash the hopper, hopper lid and the coffee bin in hot, soapy water. Rinse and dry these parts after cleaning.

5 Locate the grind control dial on the front of your KitchenAid coffee grinder. Screws are located to the left and right of this dial.

6 Turn the screws counter-clockwise with a flat head screwdriver to remove them from the grinder.

7 Pull the entire faceplate assembly gently toward you and out of the KitchenAid coffee grinder. The faceplate assembly is attached to the back of the grind control knob.

8 Pull out the burr shaft assembly, which is right behind the faceplate assembly.

9 Brush the burr shaft assembly with the burr-cleaning brush included with your KitchenAid coffee grinder to remove any debris or remaining grinds.

10 Reassemble the KitchenAid coffee grinder by returning the burr shaft assembly and faceplate assembly to the appliance. Tighten the screws with a screwdriver to hold the assemblies in place.

11 Wipe down the exterior of the coffee grinder with a damp cloth.

12 Return the clean coffee bin, hopper and hopper lid to your clean KitchenAid coffee grinder.

I have a bunn coffee grinder that keeps on jamming up everytime you put coffee beans in it. I took the front part off to clean it out every time it jams,but it keeps on doing the same thing. The model bunn...


It sounds as though your grind is out of adjustment. The grinder is probably set too fine. I have not worked on a G3 grinder but I would think it is like the Bunn G2. On the front knob you will find 2 small set screws and one larger adjustment screw (in the middle of the knob)
1. Set the selector knob to finest setting (Espresso or Turkish)
2. Loosen the 2 set screws about 2 turns.
3. Activate the start switch (you must activate the "bag switch" behind the chute)
4. With the grinder running, SLOWLY turn the center screw clockwise only until you hear a very slight whirring sound (this is the burrs touching).
5. Then, back off the center screw counter-clockwise about 1/8 of a turn, shut off grinder and re-tighten the set screws.
Check the grind in the "drip" setting by running a few beans through... the grounds should be about the consistency of sand. You should get a better flow through the machine with the grind adjusted properly. You may want to check the cleanliness of the hopper in the top... I have seen these dirty enough to impede the falling of the beans to the grinder.
Also, whenever you remove (for cleaning) the 2 larger screws that hold on the front "plate", be sure to put them back in evenly... kind of like one would with a wheel on a car- Finger-tight then slightly tighten each on a little at a time (back and forth) until tight.
Hope this helps.

I received a new lower burr grinder part from SAECO for my machine but no instructions on how to replace it. I know how to clean and replace the removable grinder part that fits into this. Do you have...


Hi
If you only got the lower burr it won't work. They should be matching burrs.
If you don't do it right, you will damage the grinder. You need a #10 Torex bit.

Insert the bit into the screw in the middle of a very clean grinder. Turn clockwise to loosen. Once the screw is out, pull the burr out, but be careful. There are ball bearings and springs under the burr. Make sure that everything is clean before reassembly. There are 3 holes in the bottom of the grinder. The springs go into the holes first. Then the ball bearings set on top of the springs. Place the new lower burr on top of the springs. A washer and the corkscrew go in next. Insert the screw in and with the bit in place turn (with a little down force) clockwise until the screw drops into place, then turn counterclockwise. It should turn fairly easy. Once you start putting pressure on the springs, try to turn the corkscrew. There is a notch that it slips into in the bottom of the grinder. Once it locks into place keep turning the screw until you start to turn the burr. That should be tight enough. Now reassemble the top burr and adjust.

Cuisinart coffee grinder keeps clogging


Unplug first. Unscrew the top. You need a long thin screw driver Phillips head is the best. Pock around the exit and entrance where the coffee beans are ground. Remember, the better the coffee and you will get more clumping of the beans. I works great. It is pain. The Chicago Clout man exits.

I suffered with a stuck grider unti for a long time and just solved the problem..... Remove the filter basket and through the front door look up twords the back left. You can see where the grinder unit sits. There is a slot area where you can stick a screw driver under the grinder unit and pry it up. Do this in a jiggling motion and make sure you are well under the grinding unit, doing so on the edge of the grinder unit underneath will not give you enough suface to work with, in fact you will just bend or crack the edge. Looking in from low on the front (kneeling on floor with unit on counter, worked for me) will let you locate where the screw driver or smal pry tool needs to go. Mine was stuck for a very long time and No amount of pulling or prying from the top would work, I made it pop out in a matter of seconds using this technique from the bottom! Good luck, I'm going to finish my cup of coffee now! :-) Steve

Take apart


My grinder went from bad to worse and finally stopped grinding (with the motor still buzzing but absolutely no grinding). Knowing I had to do something or throw it away, I pulled the clear plastic bean reservoir upward and separated it from the grinder body. I looked down the hole where beans go down to the grinder and found packed coffee ground blocking the hole. I cleaned the whole thing, put the reservoir back, and my grinder now works like new :-)
