KNOW YOUR AIR COMPRESSOR
Before attempting to use this product, familiarize yourself with all
operating features and safety rules.
Oil-free universal motor
Your air compressor features permanently lubricated bearings.
Air compressor pump
To compress air, the piston moves up and down in the cylinder.
On the down stroke, air is drawn in through the air intake valve
while the exhaust valve remains closed. On the upstroke, air is
compressed, the intake valve closes and compressed air is forced
out through the exhaust valve, into the discharge line, through the
check valve and into the air tank.
On/Off power switch
This switch is used to start or stop the air compressor. Moving the
switch to the (ON) position will provide automatic power to the
pressure switch which will allow the motor to start when the air
tank pressure is below the factory set cut-in pressure. When in
the (ON) position, the pressure switch stops the motor when the

air tank pressure reaches the factory set cut-out pressure. Moving
the switch to the (OFF) position will remove power from the motor
and stop the air compressor.
Pressure regulator knob
Use the pressure regulator knob to adjust the amount of air being
delivered through the hose.
The air pressure coming from the air tank is controlled by the
regulator knob. Turn the pressure regulation knob clockwise to
increase discharge pressure, and counterclockwise to decrease
discharge pressure. Follow tool operating instructions for
recommended pressure range.
Regulator pressure gauge
The current line pressure is displayed on the regulator pressure
gauge. This pressure can be adjusted by rotating the pressure
regulator knob.
Safety valve
This valve is designed to prevent system failures by relieving
pressure from the system when the compressed air reaches a
predetermined level. The valve is preset by the manufacturer and
