Re: Drill causes my Battary to smoke & Burn out
Do you have more than one battery and if so do they both do this? It sounds like the batery has shorted out or possibly the switch is malfunctioning and creating the short either way I would not try and recharge a battery that has these symptoms. I actually had a NiCad battery catch on fire when I charged it not knowing the history of battery. There are repair centers that usually won't charge you to check batterys/drill or maybe a minimal fee but it is cheaper than replacing batterys constantly. Good luck. Dave

Bad valve stem seals will cause smoke under these circumstances. It will get worse. The reason this happens is because the higher engine vacuum present in traffic will pull oil past the worn valve stem seals into the cylinder. When you accelerate again, the engine burns this small amount of oil causing the smoke.
Because its hot. Not only will fire burn you but any material or object that is hot can burn you or cause scorching or smoke. An electrical charge can burn you. Leaning against a hot car in the heat of the sun can burn you. Very hot water can burn you. A iron left on can burn you. A stove top burner or oven can burn you. If it's hot, IT BURNS! !
It sounds like the governor on the generator is not working or something is holding the throttle wide open. That would cause the generator to produce too much voltage for the drill. The armature in the drill has likely been toasted. That's what caused the smoke. The drill may have a short in the windings and some of the plates may even have been melted off the commutator.
It sounds to me like the drill may need its armature rebuilt or the drill may need a new armature. The outer windings may be affected as well. Just before the drill started smoking, I would guess the drill was running faster than normal.
sounds like the battery is kaput you can only charge a certain number of times or the battery has developed a memory which causes it to fail, usually caused by not fully discharging it in use and putting it back on charge when the battery still has plenty of power left. the cycle is fully discharge then recharge or check your user manual on battery
If gasoline is left sitting for a while (2-3 months) it attracts water, which could cause the "smoke" and rough running engine.
Unless it is a 2 stroke engine, no oil should be coming out the exhaust. Hold a clean rag or a bunch of paper towels at the exhaust opening BE CAREFUL NOT TO BURN YOURSELF and than check if, whatever the rag or paper towels catch is oily. If it is a 4 stroke engine, and oil is the exhaust fumes, a seal inside the engine is gone and has to be replaced.
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.
Something within the machine is discharging the battary, it does not sound like the engine is not charging, there is a tool called a negative shunt, it connects to the negative pole on the battary and enables you to connect a multi meter, this will tell you if there is a charge going out of the battary when the machine is switched off, you can then disconnect components to see which one is causeing the problem, a good mower shop should have such a tool .
disconnect battary and see what happens ,if battary holds charge put an ammeter on the earth side of the battary to see if there is any current draw if there is a draw remove each fuse individually to see which circuit it is
