Champion International Air Tools & Compressors - Recent Questions, Troubleshooting & Support

I would say you have a problem with your pressure switch, you may need to adjust it down. The pressure switch is normally located under plastic cover where your on off switch is on the compressor. There should be a screw with arrows next to it. Try that, otherwise you may need a new switch

That is made by Gardner Denver under the same model number. I could not find a manual for it but here is their site. I would contact them and see if they can furnish you one.Gardner Denver

I believe that m1820is actually the part number for the crankcase. I think it is the same unit as the Dayton brand. Look at this link for a parts list.

sounds like it..take a pencil and open it and see if it shuts off

Crankcase vent may be stopped up. Could have too much oil in the compressor.

Problem is in switch, could be from water in the diaphragm especially in cold weather....

loose wires would probably keep it from working
if you could view a working one at a store you could see how to reconnect the pressure switch.

by being disconnected the compressor probably thinks the pressure switch is open so as to show a fully pressurized tank

depends on what relief valve it is, if it is a 2 stage pump and it is the relief on the inner-stage that is lifting indicates the second stage is not pumping correctly! I would check for a broken valve. if it is the one on the discharge line to the tank, then something is restricting it, check for blockages in the line or in the check valve entering into the tank. Most important you isolate the compressor and drain all air pressure before you attempt any repairs

hi bud is it continuous oil blow off or is it a bit as if its to much then your piston rings have had it buddy

Hi

I suspect you may have either overfilled the sump or used the wrong viscosity oil, may have splashed up onto valves and patially jammed one open.

go the web and get the number to dixie sale

What bearing did you replace? Check belt tension. there should be less than 1 inch of deflection.

I CAN PROBABLY DRAW YOU A DIAGRAM BUT SEE IF YOU CAN UNDERSTAND THIS FIRST. ASSUMING YOUR STARTER COIL REQUIRES THE SAME VOLTAGE OF YOUR COMPRESSOR. 230V MOTOR = 230V COIL ON STARTER. YOU HAVE 2 OR 3 HOT WIRES ATTACHING TO THE TOP OF THE STARTER ( 1 PHASE OR 3 PHASE). TAKE A JUMPER WIRE INSERTED UNDER THE SAME LUG AS 1 HOT LEG AND GO STAIGHT TO 1 SIDE OF THE COIL. THEN TAKE ANOTHER JUMPER WIRE FROM ANOTHER HOT LUG - PASS THRU THE TRIP PACK AT THE BOTTOM OF THE STARTER ( IN AND OUT) THEN GO TO PRESSURE SWITCH. TAKE THE OTHER PRESSURE SWITCH WIRE TO THE LOW OIL SWITCH. TAKE THE OTHER LOW OIL WIRE TO THE OTHER SIDE OF THE STARTER COIL. THEREFORE YOU WILL HAVE ONE SIDE OF THE COIL HOT ALL THE TIME AND WAITING FOR THE OTHER SIDE TO GET HOT. AS LONG THE OTHER LONGER CIRCUIT IS A COMPLETE CIRCUIT IT WILL WORK - IN A SERIES THE TRIP PACK SAYS OK, THEN THE PRESSURE SWITCH SAYS OK, THEN THE LOW OIL SWITCH SAYS OK AND THEN VOLTAGE GOES TO COIL AND PULLS THE STARTER IN. IF THIS IS TOO CONFUSING SEND ME AN EMAIL AND HOPEFULLY A PIC OF YOUR NEW STARTER TO [email protected] AND I'LL TRY TO HELP YOU FURTHER. HOPE THIS HELPS.
