On/off switch just buzzes when I push start. I can't find a reset button on the JET XACTA SAW DELUXE 3HP,1PH, 50" RIP table saw. It's getting electricity- plugged in and continuity of electricity is present from switch to motor. Does the motor have a reset button or is there some problem with the on/off switch?

I am not sure what model you have but they have this saw in two models one is 230 volt only the other is 230/460 volt.
But that is not a 220 volt circuit. 220 volt is single phase where the 230/460 is a 3 phase circuit.
Look on your motor and see what the power requirement is.
if you have a different machine then the one I am looking at I would switch over to the auto function.

draw bar ...you can buy them from enco or msc for about $20-$30. Give them a call and tell them the machine you have...mention you have variable speed.

Usually the reset for table saw is on the motor itself
Crawl under the table and check it out & check your motor name plate (use a digital camera to photograph the name plate so you can see it large on your computer and have a record of that information)
Look for oil caps at the bearing ends of motor, to see if your motor can be oiled using 3-in-1 oil

If your saw is shutting down, you may not have enough electricity for the motor
Look at motor name plate for volts amps or watts.
Now figure how much electricity your saw need using the formula Volts x Amps = Watts

Next, look at the circuit breaker and size wire
15Amp breaker = 1440+watts
You can figure the breaker load using V X A = W

Next look at your wire going to table saw
14 gauge wire for 15 amp breaker
12 gauge wire for 20 amp breaker
10 gauge wire for 30 amp breaker

You might benefit by running bigger wire to the saw. And adding some oil in the oil caps.
I oiled my table saw and then ran a dedicated 30Amp wire to it, and it runs real good for a 25-year-old craftsman.

Jet's Manual site is here. There are a number of manuals for Jet table saws there. I believe the exact manual you want is here though.

If this helped, please vote. Thanks!

did it trip your outlet breaker? check breaker with volt ohm meter. hope the motor didn't go to ground.

Adjust the stop screw under the saw top plate.

I took the front cover off of the switch and noticed the portion of the switch the off button contacts was fully depressed and would not slide back to its proper position. I lubed (silicone) the slide portion of the off switch and cycled it manually to free it up and distribute the lubrication.

The contacts in the switch are burnt, replace them.

There are two common blades: Eight-Inch Table Saws are a good choice for crafts and other applications associated with thinner stock.Ten-Inch Table Saws provide the extra cutting depth needed for angled cuts in thicker stock.
