How To Stop; Before First Start-Up - Porter-Cable CPF6020 Instruction Manual

Air Compressor Pump (not shown): 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.
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
after the unit reaches "cut-out" pressure.
Motor Overload Protector: The motor has an
automatic reset thermal overload protector. If the motor
overheats for any reason, the overload protector will
shut off the motor. The motor must be allowed to cool down before restarting.
The compressor will automatically restart after the motor cools.
If the overload protector shuts the motor off frequently, check for a possible
voltage problem. Low voltage can also be suspected when:
1. The motor does not get up to full power or speed.
2. Fuses blow out when starting the motor; lights dim and remain dim when
motor is started and is running.

How To Stop

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

Before First Start-up

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.
NOTE: Always drain tank on a washable surface or in a suitable container to
prevent damaging or staining surfaces.
Serious damage may result if the following break-in
instructions are not closely followed.
