Check the check valve, disconnect the tube between the pump and the tank and power it up and see if it still humms.

Sounds like you need a higher current circuit. When a motor starts up, there is a higher than normal current draw, usually 2x to 4x the running current. When it starts up against cut in pressure, there is even more resistance and hence more current draw than when starting up against no pressure in the tank. So, your circuit is capable of providing startup current with no presure, but with pressure it is drawing more current and tripping the beaker. Don't just put a higher rated circuit hreaker in unless you want to buern down your house. Get an electrician to measure the starting current of your compressor and wire up a circuit and outlet that will handle that current safely. That said, the advertising for the compressor says it can run on a standard (15 amp) household circuit, so your motor may be drawing excessive current. Either way, an electrician can help you. Another option is to add capacitive start to the compressor, but, again, a good electrician will have the solution.

If the compressor motor is dual voltage then yes, otherwise no.
Notice the current draw is twice at low voltage than that of high voltage in a dual voltage motor.

Pneumatic tools are rated in cfm (cubic feet per minute). Your 1 HP air compressor is rated at probably not more than 3 cfm while the 1/2 " impact driver needs at least 8 cfm, maybe 12 chm of air.
The compressor must provide more chm than tool rating needs.
It is a problem, by the time you look at five horse power air compressors and larger, a lot of electric power is needed. A circuit of 220 volts, 20, 30, or more amps would be required to run those large expensive compressors.
If you can, return the air tool and get a good electric tool instead.
Leave those high air volume air tools to shops that are so equipped to use, or invest if you must.

not completely familiar with that exact model but on other ones if there is a jam it wont fire or was jammed and not reset, meaning the driver( what drives the nail) has to be in the up most position. so use a long thin rod and push it back to the top and check that the magazine has nails or that the feed is good. if want to try with no nails you have to leave the magazine open. but should work with charged battery and make sure any adjustment switches are on or off cant be in a middle position. but know from the dewalt framer cordless the driver has to be up before it will fire.

try a little air oil in th inlet hose . they (seals) do dry out

Mine did that and i shot a bit of WD40 on all the moving parts. It works now. I think it was stored in a damp air place and corrosion set in.

This compressor has a 33 gallon tank and a 3 to 5 hp (rated)motor. Sears , however, rates their motor power rather differently. I would guess that the actual hp is more like one to one and a half horsepower, going by the amp draw. Usually, a 3 to 5 hp range compressor will only run on 220v and this unit is 110v.

depends where it is
If it is from the bottom it may be a rusted out tank ( don't fix)
if it from around the weld for the boss ( rusted out -don't fix
if it is around a plug thread just reseal
remember that compressor tanks contain oil and water and welding before completely evacuating with nitrogen gas will cause an explosion
