Q:

I have a "permanently lubricated" Sears compressor. It's 20 years old. Do I need to lubricate it?

A:

You do not need to lubricate anything on your compressor. Over time the o-ring on the piston and the sleeve it runs in will wear and the compressor will not be as efficient, then you will need to replace those parts and the gasket on the head.

As long as the compressor is working I wouldn't recommend doing anything to it.

Q:

I have a craftsman air compressor (horizontal 33gal). It starts fine when it turns off and you use it , it will try to start then blow the breaker. Any ideas?

A:

The check valve is attached to the tank and the discharge line from the compressor attaches to the check valve.

When the pressure switch is satisfied and turns the motor off, the check valve stops the pressure inside the tank from going into the discharge line. Pressure is bled off the discharge line through the small line that goes into the pressure switch. This enables the motor to restart without pressure.

When the compressor trips a circuit breaker when trying to restart, the check valve is usually leaking pressure into the discharge line.
