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.

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 protec-
tor. 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 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 Auto/Off lever in the "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".
HOW TO USE YOUR UNIT

Before Starting
Do not operate this unit until you read and understand this
instruction manual for safety, operation and maintenance instructions.
Break-in Procedure
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 Auto/Off lever is in the "Off" position.
2. Check oil level in pump. See Oil paragraph in the Maintenance section for
instructions.
3. Recheck all wiring. Make sure wires are secure at all terminals connections.
Make sure all contacts move freely and are not obstructed.
4. Open the globe valve fully to permit air to escape and prevent air pressure
build up in the air tank during the break-in period.
5. Move the Auto/Off lever to "Auto" position. The compressor will start.
6. Run the compressor for 20 minutes. Make sure the globe valve is open and
there is minimal air pressure build-up in tank.
