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

I've been working on air compressors for a while now and so far haven't found any that give a specific amount of oil to put in the air pump crank case. They all have one of two methods to get the oil to the proper level. First, and my favorite, is a sight glass at the bottom of the crank case. About the size of a quarter, it lets you see how much oil is in the pump as you add it. Usually they have a red center dot which is where you want the oil level. A little over or under is OK but the sight glass should not be completely full or completely empty, both are hard on the pump and drive motor. Another method is a dip stick usually on the end of the fill hole cap. Only bad thing about these is you have to put in some oil, check the oil level with the dip stick, then add more oil and check it with the dip stick until you get to the full mark. Again, not over and only a little under is where you want the oil level.

if it no on the motor ,it will not have one

indicates reed/ poppet valve problem possibly a broken spring in a head

Check all wring. Remove cove and see if you can turn over by hand.If you can't unit is broken/frozen.it should run on 120. look at the plug if prongs are vertical the unit 120vac. Look on motor wire box if it can be rewired it will be there. I doubt this unit is designed to operate on 120vax. The mots/pump assembly is not available for purchase. there are a few repair parts available. do you want to spend the time and money for rewind.? good luck

M40F30, 40uf +- 10 %, -40/70 C , 370 VAC 50/60 HZ. Mallory 400-480 MFD ,165 VAC I show two, one is a start and one is a run. The best bet is amazon.com they are showing them for about 10 to 15 dollars

Could be piston O rings, worn cylinder line, worn reed valve-plate assembly, worn discharge check valve, leaking unloader valve. Need info if unloader is leaking or unloader tubing is leaking. The Cheapest and quickest is to remove valve plate assembly and inspect valve plate. Suction side should hold water and discharge valve should hold water placed on bottom of plate.

it is possible that it is not the compressor but the breaker has reached it's end of life. I'd change it to eliminate that before throwing any more parts at the compressor. My suggestion anyway.

if you are using quick connects it is likely that you need to wrap with PTFE thread tape to ensure seal... If you aren't that would indicate a leak in the tool meaning the tool should be replaced...

Only the motor needs its feed connections changed from one voltage to the other. Someone knowledgeable about motors should do this. But, not all motors have multiple voltage capabilities. I have a Craftsman 2 HP compressor myself that only will run on 220. Check your manual on this. If you can't change the motor, it will probably be cost-effective to run a 220 line over buying a new motor.

Jam, low pressure

Does it start when the tank is pressurized?

I have worked on compressors from 15 PSI all the way up to 5000 PSI and everyone of the regulators I have seen bleed the pressure of when you dial it down and you can hear it.

You can download the manual in the following link. I think they charge a few dollars for it. https://www.searspartsdirect.com/partsdirect/user-manuals/900684253-CRAFTSMAN-ELECTRIC%20BRAD%20NAILER-manual
