It might be one of the following: 1. Voltage changeover selector switch has blown - check if the power is still there before it enters the switch and still there after it leaves. 2. Breaker has failed on that leg - test before and after to see if working correctly 3. The plug socket has failed - Look for burn marks where wiring enters. 3. There is a fault in the alternator - see 2nd video down on this page for testing:https://www.generatorguru.com/help-me-fix-my-generator-repair-advice/ Hope this helps you.

You might want to check the other cap but also verify engine is up to speed. Output power SB ~ 60 hz.

DO not turn on your generator you generate over your rpm level 3000 and will have an too high output and will burn your electric field of the compressor. First is to control your pressure check-valve on the tank of the compressor and if there is on the compressor brand model ? a pressure relief valve most on the pressure (pressostatswitch) then that will in most cases with a little hose also on the check valve and should work smoot but the check valve if it will not good close the tankpressure then it will give a very high pressure load and sometimes you can hear it , the checkvalve inside will have a spring and a rubber piece control for rust flakes or any problem sometimes the rubber part can also be smoothed on sandpaper. in most cases the check-valve and pressure relief will have problems on metal pieces then the pressure relief will blocked and will not close , but sometimes not.

Choose your brand

Thank you for the useful information

Remove spark plug. Pour a small amount of a lubricant like Marvel Mystery Oil in and allow to soak for a day or two. Repeat this process at least two times. Then try to turn the engine over slowly by hand. Do not use the pull rope or starter. You need to use a wrench, pry bar, etc. You may have to remove the engines cover to access the flywheel to turn it.

Well it's gonna have to be the switch then. Just for kicks and giggles see if you have continuity on both sides of the switch with the trigger pressed

The same thing happens in cordless drills that they do not start and only the led light works. In cordless drills case this means it need a new switch to be replaced. If it is under the 3 year warranty policy it is changed free of charge from dewalt. If it is more than 3 years then you have to pay for the switch but it is not that expensive.

You might have a thermal issue with the ignition coil shutting down after it gets warm. Happens.

Ifyour carb is leaking fuel then I would suggest that the carb float needle has got stuck open. To fix this you need to:

1. Remove the carb bowl taking note which direction it faces (I usually mark a line from top of the carb and down the bowl with a marker to make this easy.)
2. Check the state of the fuel and residue left in the bowl.
3. Slide the pin out from the float hinge (be careful not to lose any springs that might be seating the float needle.
4. Inspect the float needle tip. It should be smooth with not scratches etc. (if yours has rubber on the tip, also be sure this has not perished.)
5. Clean the float needle and clean the jet hole it sits in.
6. If there was a "gunk" or dirt in the carb bowl when you took it off, remove and clean all the other removable components.
7. Re-assemble. Making sure the air screw (brass with a spring) is set a 1.5 turns un-done from lightly done up.

If you find that the carb is still leaking, this could be due to the ethanol in the fuel, eating away the components. We do sell both Carb Repair Kits and Carbs for your Generator.

there will be a oil level control unit on the engine sump that has a habit of failing on a regular basis test it or replace it.

If you go to google images for your model there are various exploded views available. If you work down them you'll see an armature with a small gear on one end. If you have no drive in any gear my guess is that gear has disintegrated. If you remove the 4 screws holding the gearcase to the motor body and carefully pull them apart, lay the parts out according to one of the exploded views. You will find that gear, just be ready for parts to fall out and take care where they came from. If the armature is available it may still not be an economical fix. You may be better searching a dealer who has a current one on offer.

Hi Dan: I'd be suspicious of a problem with the piston or connecting rod bearings. My first step would be to remove the head and look for damage like scored cylinder walls or broken piston, and also to see if the problem is gone with the head off.

On some chargers, when the light blinks rapidly, it means that the battery is bad. Try looking up charger information on-line.

It sounds like you have a defective battery. I would suggest contacting one of our Factory Service Center's to see if your battery is still within warranty. Please see the link provided. You can also give as a call at 1-800-4DEWALT. DEWALT com

Unless it is rated for 220-50/110-60, you will need the converter. Besides the 110V US plugs won't plug into the 200V UK outlets.
