It sounds like some oil has gotten onto the armature of the motor where the brushes are. That will cause the symptoms of what is happening.
Get some Electric Motor and Brake Parts Cleaner at an auto supply house. Note: It is not flammable.
If you cannot find it. Get the Regular Brake parts cleaner.
1 Allow the saw to cool to room temperature.


3 Spray the cleaner it into the vent holes
4 Carefully remove the brush caps (Small Black things that look like buttons) There are two of them.
5 Spray inside where the brushes are.
6 Let it dry out for a day.
7 Re-assemble
8 Plug it in and see how it works.

If it is still running roughly after you do the above steps. Get it serviced. There is damage to the armature and brushes.

Hope this helps.
Best, Mark

Blue smoke usually indicates burning oil. There may be some residual oil in the cylinder that burns off when the engine is started. Do you use much oil when the engine runs? Keep an eye on the oil; level.

Smoke come from motor and now drill hardly moves .is new motor required or brushes

You will rarely get smoke from the brushes on electric tools. Smoke is usually a result of either the armature or field coils getting hot enough to melt or burn the varnish insulation off the wire which results in a loss of or no power because of shorting in the windings. You'll have to replace whichever part burned the windings and find out what caused the problem or you'll burn the new part the same way the original burned.

I have a DeWalt D55168 type 3 air compressor that the motor brushes keep sparking and smoking.

If the compressor is relatively new and performs well, it is probably not an issue. Brushes always spark on the commutator but without seeing the extent of the sparks it is hard to tell for certain if it is "too much" or not. I wouldn't expect any significant smoke from the brushes and commutator or the armature unless it is brand new and the oils from manufacturing are being burned off. If it is a very old machine, it is possible the armature is shorted out and needs to be replaced.

If, on the other hand, it is not brand new, but a couple years old, has had use, but not heavy and continuous and you just see small sparks coming from the brushes, then it is probably ok. If the sparks seem larger than what you are accustomed to and you are seeing smoke coming from the motor at all (presuming it is not the brand new situation noted above) then the armature may be starting to short out and/or the windings in the motor may be starting to burn out. Electric motors that are used within their design constraints (not overloaded, not run on low voltage, not run continuously if not designed for that use, not overheated) do not tend to burn out. However, if the windings get covered with sawdust (which insulates them), you run the compressor continuously for hours on end, day after day, especially in a hot environment and/or with low voltage, then you have probably overheated the windings and the motor is burning out. For a compressor of this size and quality, it would likely cost more to have the motor rewound than it cost to replace the compressor. Also, if it has failed from overly hard use, rewinding the motor will not prevent another burn-out, you need a larger, more durable compressor.

Smoke from Motor

If oil got on the brushes, this can happen, and it will clear. It can also happen when windings have shorted out from being run too hot with subsequent failure of varnish. The brushes will tend to arc and the commutator contact bars begin to erode and melt. The motor may continue to run albeit slowly and without power.

Also too, sometimes the speed control circuit flames out and appears as smoke from the motor. in which case the motor becomes nonfunctional.

The same can happen when wires get shorted out.

The motor running slower was the motor starting to burn out. The "almost start" is the brushes making intermittent contact with the armature in the motor.
Your machine needs a new motor Pam.

I have a dewalt dw364 circular saw. the motor is running slower and sparking internally. The motor also starts smoking while using. A suggestion was to replace the brushes.

I agree with replacing the brushes, and don't use it until you do, so no damage is done to the motor. If it is smoking there is some overheating. Best regards and good luck.

When running it smells like something is burning


If it smells like burning rubber, then your belt is probably slipping due to having lost tension and needs to be replaced. If it's another smell, it could be the motor burning out, but that is often accompanied by smoke. There could also be something caught around the revolving brushes in the cleaning head. Lie the vacuum on it's side and make sure you can spin the brushbar freely by hand. Also check for any debris entangled in or obstructing the brushes. This would also cause the belt to slip resulting in a smell of burning rubber. It could also damage the motor so I suggest not using the vacuum until the source of the fault has been determined.

Instructions on replacing the belt can be found in your user manual. If you don't have one or need further instruction on how to do this, please post back for further assistance.

Water comes in but will not begin to wash

hi there......this problem is usually related to badly worn brushes in the motor...a quick way to check this is.....(1) remove the machine from its position...bringing it foward enough to tilt it back sufficiently allowing you access to the botom of the machine...(2) insect the motor for signs of black carbon dust...indicating brush ware....gently tap the motor with a small hammer...or suitable object....stand the machine uright machine....if all is ok machine will run indicating a set of replacement carbon brushes are required....failure to run indicates brushes very badly worn and possibility of damaged motor...remove the rear panel of the machine...remove the belt...remove the motor for inspection..of armature and brushes...any burn or discolouring marks on the copper brush track...indicates a failed motor..which will require replacing....
