Check Valve: When the air compres-
sor is operating, the check valve is
"open", allowing compressed air to
enter the air tank. When the air com-
pressor reaches "cut-out"
pressure,
the check valve "closes", allowing air
pressure to remain inside the air tank.
Check Valve
Pressure Release Valve: The pres-
sure 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 sec-
onds.
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
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.
To restart:
1.
Place the On/
Auto/Off
lever in the
"Off" posi-
tion.
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 com-
ing into the pump. This filter must
always be clean and ventilation
openings free from obstructions.
See
"Maintenance".

Recheck all wiring. Make sure
wires are secure at all terminals
connections. Make sure all con-
