How To Use Your Unit; How To Stop; Before Starting - Porter-Cable C3101 Instruction Manual

Cooling System (not shown): This compressor contains an advanced design
cooling system. At the heart of this cooling system is an engineered fan.
It is perfectly normal for this fan to blow air through
the vent holes in large amounts. You know that the
cooling system is working when air is being expelled.
Air Compressor Pump: Compresses air into the air
tank. Working air is not available until the compressor
has raised the air tank pressure above that required at
the air outlet.
Drain Valve: The drain valve is located at the base of
the air tank and is used to drain condensation at the
end of each use.
Check Valve: When the air compressor is operating,
the check valve is "open", allowing compressed air to
enter the air tank. When the air compressor reaches
"cut-out" pressure, the check valve "closes", allowing
air pressure to remain inside the air tank.
Pressure Release Valve: The pressure release valve
located on the side of the pressure switch, is designed
to automatically release compressed air from the compressor head and the
outlet tube when the air compressor reaches "cut-out" pressure or is shut off.
The pressure release valve allows the motor to restart freely. When the motor
stops running, air will be heard escaping from this valve for a few seconds. No
air should be heard leaking when the motor is running, or continuous leaking
after unit reaches "cut-out" pressure.

How to Use Your Unit

How to Stop:

1. Set the On/Auto/Off lever to "OFF".

Before Starting

Break-in instructions
This procedure is required before the air compressor is put into service and
when the check valve or a complete compressor pump has been replaced.
1. Make sure the On/Auto/Off lever is in the "OFF" position.
NOTE: If quick connect is installed, pull coupler back until it clicks to prevent air
from escaping through the quick connect.
2. Plug the power cord into the correct branch circuit receptacle. (Refer to
Voltage and Circuit Protection paragraph in the Installation section of this
manual.)
3. Open the drain valve fully (counterclockwise) to permit air to escape and
prevent air pressure build up in the air tank during the break-in period.

Serious damage may result if the following break-in
instructions are not closely followed.
