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 pres-
sure 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 com-
pressor head and the outlet tube when the air com-
pressor reaches "cut-out" pressure
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".
