Wacker generator surges

No way to tell for certain... Could be a burned out motor or the bearings could have ceased. Often, cutting debris gets sucked inside the motor housing which collects over time. Blowing out your power tools with an air line helps them last longer and the motor breath easier so it doesn't overheat. There are a lot of tool repair shops that can usually fix power tools for half the price of a new tool. Angle grinders usually burn out on me within 120 days of purchase; they don't make them like they use to. My tool repair shop can fix it for me in a day or two, and it ends up lasting years after I paid to have it fixed. It's definitely cheaper than buy another grinder that is just going to burn out in a couple months anyways. The repair shop does such a great job that the rebuilt tool is better than the factory new tool.

Sounds like it got too hot and burned the motor up. Had this with a making grinder. They are a piece of junk anymore. Hope it's still unber warranty.

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.

Sounds like the generator unit (sometimes called the generator head) has overheated and melted the insulation in the windings. This is the same as an electric motor "burning out", and if this is the case, then the generator is toast. If you happened to notice that the lights or fans were getting dim or slowing down before the breaker tripped (without the gas engine slowing down) then this is most likely the case and you generator is toast. But if the output just suddenly quit, then it is possible that some smaller electrical component has failed. In any case, it's not something external that you can easily reset or replace. Sorry for the bad news.

Well burning and smoke is either a switch or motor. Disconnect the motor and run it with battery voltage and no switch. If it's still slow and smokes it's the motor if not it's the switch. The other one sounds more like the switch but could be the motor. Testing would be the same as the other. On the 18 volt open it up and see if the reversing lever got hung up. It may be that you can line it back up and be ok. More likely it's a bad switch and needs to be replaced.
All these tools have static sensitive switches and need to be worked on at a static free work station.
Hope that helped..

Hello, ushicks/me hillybilly. One question how old is the fuel in then generator tank,Hey. If it has a fuel filter replace it. Modern gasoline is junk fuel and after a few months it looses some chemical proprieties. GB...stewbison

Most common problems with small grinders in general (all brands) fall into two main catagories. Low power situation and lack of lubrication /debris or maintainance. Electric power tools are used with an extension cord. If too long of cord or improper gauge wire is used, the tool will heat up and burn the brushes, switch or copper winding (lower life of tool). If you feel the tool getting hot either let it cool or check power supply. Tools such as grinders generate lots of dust/debris that enters the tool. Abrasive dust entering tool prevents proper cooling and eats varnish off winding / wears carbon brushs and commutator. Grinders/polishers get packed inside with fluff coming off bonnets preventing cooling. All this overheating prevents grease from properly lubricating gears. Check gearcase for good lubrication and keep inside of the grinder clean. Good luck

1. disassemble the plastic parts(container and cover of doser)
2. search for rewinding workshop near your place
3. during disassembling the grinder the lower burr plate should be disassembled, do it carefuly
4. since motor is burned out grease of bearings went out from the heat, you will need to change them also.
5. require from workshop during winding to integrate resettable termo protector at wires(if sometime heats up again to prevent burning)

just remove the controller, unplug the thin red wire from switch, unplug white plug for leds, cut both black wires and both red wires from controller unit.remove controller unit. then connect red wire from switch to red wire from were battery connects, do the same for the black wire. overload protection now removed, be careful if switch is in the on position when you connect battery grinder starts!!!

It is possible that you overloaded it in high range and maybe stalled it out. Usually when the motor burns it is from overloading/overheating. If this is a newer tool I would try and take it back for warranty repair and not say anything about the smell. Its worth a try, some of the motors for the cordless tools are around 50-60 dollars
