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.
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 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" 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".
