Dipstick: Indicates the amount of oil in the pump, the +

mark indicates full and the - mark indicates oil needs to

be added. See Oil paragraphs in the Maintenance section

for instructions.

Motor Thermal Overload Protector (not shown): 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.

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".

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 continuous leaking after

unit reaches "cut-out" pressure.
