Need to install power cord to terminals on 220 AC motor

Century / Magnetek motors are used on many compressors but usually is an upgrade to have the option to easily switch from 110 to 220. Dewalt, Rol Air, Jenny, Emglo and others are considered high end compressors and come with switch for selecting voltage. One still must change the cord if selecting 220v setting. One thing in common is that 115v motors are never more than 2-3 HP because the amp draw for anything over 2hp is likely higher than 20 amps and would trip most common outlet breakers. You noted that your motor sticker lists 6.5 hp at 15 amp 220v so it could not work with 110v because it would draw over 30 amps and just not be practical. Magnetek motors are very good quality and most always state on sticker 110/220v and show wiring diagram for proper connection. Your compressor was most likely built to be stationary and be hardwired into an outlet/switchbox with heavy duty wiring or special cord to run such a high hp motor. You made a great buy however, because the motor alone lists for several hundered dollars alone. You could replace the motor with a 110v but you would loose the fast performance / recovery of that 6.5 hp motor. Like replacing a v8 engine with a 4 cyl. but expect to pull same load, not likely. Good luck with your purchase, and post again if you have other question.

check that a cord around the coil hasnt come in contact with the crank

Make sure you are plugged direct. No extension cords

When looking at the switch it self, There will be 4 contacts. On the switch 2 will be labeled Line (Power in) and 2 will be labeled Motor (power out to motor) . Hook the black and white wires from the power cord to the line side (Either contact, it does not matter). Hook the 2 black and white wires from the motor to the contacts labeled Motor on the switch. The remaining 2 green wires (one from the motor and one from the cord) are to be grounded to the case on the switch.

Does the unit have a starter or just a pressure switch , if just a pressure switch it should be marked with line and motor , the wires on the motor should go to the motor terminal and the line terminals are the power supply , if the unit is 110 volts make sure you put the wires on by color , the white wire goes to the motors white wire and the black to the motors black wire , if this is 220 volts it does not matter which wire connects just put the two black wires on the line terminals. One wire per terminals please.

it should be in manual because that compressor run both ways. it really not going to make start up faster. how long is the cord and the gauge of wire.Compressor company only give you a cord that plug’s directly into wall, after that your on own see the manual for cord size.

I can't blame you for askig, but here's my response. 5 HP is 3750 running watts. or about 35 amps at 110 volts and it would take somewhere around 50 amps to start it provided the motor could even be wired for 110 which I don't believe it can and for that exact reason. I'm sorry, but it's just not practical.

I'm looking for a owners manual for a colman powermate air compeser modle cl0502710

you can try at mastertoolrepair.com they have parts just have to see if your model is in there system

your correct either the valves are worn or maybe just need cleaning as for the gaskets,idont know what part of the world your in but check out coleman on the internet or failing that ,i have maid these from gasket material suuplied from my local bearing supplier
