Therma Overload Switch

replace motor have motor rewound. The overload is a safety device to prevent motor damage, you may have made things worse by holding reset in.

I would return it to the store, or have it fixed under warranty. You obviously have a defective saw. Dewalt is a reputable company, and they make high quality tools, but defects do op up once in a while from all manufacturers.
It sounds like your saw has a defective heat sensor, and it is sensing the temperature incorrectly and shutting the saw off to protect it.

If the motor isn't HOT when it kicks out you need to replace the thermal sensor is all. If it IS, then the motor needs replacing.

Why this is in sewing machines I will never know.

But this is an example of pushing a saw beyond it's limits. At best you should have cut one post, shut the machine off and let it cool... then go for the next. (Better yet get a friend with a saw mill saw the thing down for you)

I believe you have burned out your motor. Off the store you go....for a new one.

Locate where the choke lever is for your generator (under the petrol tank), you ought to notice a star headed shaped screw connected to the governor shaft (if you bend and look closely further beyond the choke lever; still under the petrol tank) which is linked to the carburettor housing/assembly. You need to increase/turn clockwise (using a star screwdriver) on this screw.

Your generator engine sound will change/high a bit because the engine speed will increase.

Reconnect your 1800w chop saw (load) and see if your generator can "effortlessly" accommodate it without shutting down otherwise, increae the turns on this adjustment screw attached to the governor shaft till your generator operates/stabilizes with the load (1800w) connected

Hi,
You did not say what fuel you running the motor on??? It sounds like it may be LPG or Propane.... is so then it seems as though you do not have enough surface for evaporation...

Hi,
The first thing that I would check is the wiring to the saw. My guess is that the wire to the saw or the cord is not heavy enough.
As saw like that can pull a lot of amps. Probably 15 or more when working hard. What happens is that when the amp draw goes up and the cord is too light, the voltage drops which increases the amps. and starts a vicious cycle...
The one thing that finally gives is the internal overload in your motor.

Try running heavier wire or a heavier extension cord if you are using one.
#12 wire or a 12 wire cord would be minimum, if running over say 50 feet then you should be looking at #10 wire.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Your carb may be the issue but your ignition coil could be the culprit. Once they start going bad, they can act up intermittently or give various symptoms from day to day. The fact that your saw dies at full load or under load, probably means that when your saw gets hot or requires more spark, your coil is not able to provide it. Your carb is easy enough to clean out, you can take it all apart and clean all screens, etc....

I just replaced my coil due to the exact same symptoms and now my saw runs great. $60 off ebay and you can put it on in 15 minutes yourself. Check your carb first though

What are you cutting? What type of blade, power supply, etc are you using. It sounds like the thermal overload is cutting out.
Try looking for a little (red) button on the motor itself that pops out slightly when the motor cuts off.(due to overheating). If you push that in, will the saw start running again?

Probably the motor is getting too hot and the thermal overload switch is shutting it down.Usually means bad motor or dirty motor. You'll have to take it apart to see. Model # and Brand would help.
