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.

Risk of Unsafe Operation. Serious damage may result if
the following break-in instructions are not closely
followed.
This procedure is required before the air compressor is put into service and
when the check valve or a complete compressor pump has been replaced.
1. Make sure the On/Auto/Off lever is in the "OFF" position.
2. Check oil level in pump. See "Oil" paragraph in the "Maintenance" section
for instructions.
NOTE: Pull coupler back until it clicks to prevent air from escaping through the
quick connect.
