Emglo Airmate Compressor

I have an old (1980's) Emglo Airmate compressor. It is 1-1/2 HP with two side-by-side tanks and a wheel in between on one end and handles on the other end. The tag says Model AM77-8P and Serial # 060487718.
The problem is when I turn it on it is very sluggish and hardly turns over. If I leave the power on it will pop the fuse on the motor. The only way i can get it to work is by plugging and unplugging in short bursts without popping the fuse and eventually it will turn over and run. After that it will come back on okay everytime the pressure drops to the point it needs to pump up again. It's just the initial start that has a problem. Any suggestions on how or if it can be fixed?

Does it start OK when there is no pressure in the tanks? If so you might have a bad unloader valve.

Welcome to the forums.

In addition to Danes info.... it could be weak capacitors too. They're mounted to the motor.
I couldn't find any service info on your exact model so a picture would be helpful.
How to insert pictures.

Those used powerful motors that require a good supply to start.
It needs to be on a 20A circuit and extension cords are not recommended.

Representative picture.....

Emglo Airmate

It has trouble with the initial start if it has not been used for a day or more. Doesn't matter if it is pressurized or not. Once I get it started it will pump up to full pressure and turn on again no problem whenever the pressure drops below the pressure setting. It will run normally for as long as I need to use it. The problem only happens when it is "cold" and has not been used for a while.

I've had several emglo compressors, and you typically need to replace the pressure switch/unloader when it starts acting up. Not hard to do.

That's a direct drive compressor. could still have capacitor issues.

Since it has trouble starting even when the tank is empty I'm thinking capacitor. If it were a bad unloader it should start OK when the tank is empty and mainly have trouble when it's pressurized.
