Porter-Cable C7550 Instruction Manual page 13

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" pres-
sure 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: This motor has a manual thermal overload protec-
tor. 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. To restart:
1. Place the On/Auto/Off lever in the "Off" position.
2. Allow the motor to cool.
3. Depress the red reset button on the motor.
4. Place the On/Auto/Off lever in the "On/Auto" postion to
restart the motor.
Air Intake Filter (not shown): This filter is designed to
clean air coming into the pump. This filter must always be
clean and ventilation openings free from obstructions. See
"Maintenance".
