The toro electric leaf blower smokes at the connection with the extension cord. I have used two different 100 foot extension cords & had the same problem with each.

It appears that for some reason, the connection at the extension cord, overheated. Could be caused by: 1. a problem with the vacuum unit (bearings, jamming up, something like that)
2. The extension cord itself was defective. Could have been abused, moisture could have broken down the "contact" or the point of contact or blades of the extension were loose and caused excessive current draw at that point, overheating the device.
Or, it could have been a factory fault with the extension.

Plug your blower into a good receptacle, and see how it runs. If it is
sluggish or not coming up to speed, the problem could be in the unit.
Check manufacturer's recommendation for extension cord size and length.

Obviously, that power cord is now shot. But, if you are pretty handy and very confident, simply splice the cord. Make sure you hook up the wires to the correct ones and plug it in make sure it is all electrical tape back together so the wires have absolutely no chance of touching each other, and if that does not work, I would say that there is a defect with the Toro

Don't add an extention cord to an extention cord! Buy a 100' 14/4 extension cord and tie the end to the fence so it won't come un plugged.
If the plug keeps popping out of the short cord at the blower,wrap the cord around the handle to prevent disconnection.

Sounds like the brushes are worn out and in need of replacement, if available.

I could be a variety of things. Did you have a very long cord on it? did the cord loosen the plug? are you sure the outlet is still good, Also you may need to wait a few hours for a thermal reset to reset.

If it has not run for awhile, check the brushes. they might need to be replaced. The plug is usually moulded right on power cord. That might have to be replaced because if there is a problem with a broken or disconnected wire right at plug there is no way to see it. Hope this helps.

You must use at least a 12 guage extention cord . Your current cord mostlikely can not handle those amount of amps for long duration of time.

If it is getting hot enough to melt the electric cord and the extension cord, get rid of it. The over-heating is most likely from the brushes in the motor, which means, unless you are a licensed electrician or know one, the unit should be scrapped. Replacement parts for these electric blowers are priced such that it is cheaper to buy a enw one than to fix the old one.

If an electric motor is smoking, most likely it is in the process of burning out the windings in the motor. This usually starts from using an extension cord that has too small a wire or a cord that is too long. when you do thid you are forcing the motor to pull more amps than it should to make up for the voltage loss in the cord.
The fuel for the electric motor is a term called watts. Watts equals volts times amps. If the voltage drops then more amps are needed to feed the motor enough watts. This caused the motor to over heat and this melts or breaks down the insulation on the windings. When this happens the motor starts to short out and once this happens then you can not save the motor.

Electric lawn equipment should be used with #14 or #12 (never use #16 or #18 gauge ) guage extension cords and should not be used with cords longer than 50 feet. Also you should not run the equipment more than 10 minutes with out a 30 minute rest.

sounds like your blower is drawing to many amp`s for the cords your using for this
