OPERATION
Applications
Air compressors are utilized in a variety of air system
applications. Match hoses, connectors, air tools, and
accessories to the capabilities of the air compressor.
You may use this compressor for purposes listed below:
● Operating air powered compressor and tools requiring less
than 5 SCFM @ 90 PSI.
● Powering pneumatic nail guns, inflating tires, cleaning /
blowing with pressurized air.

WARNING: Do not allow familiarity with
compressor and tools to make you careless.
Remember that a careless fraction of a second is
sufficient to inflict serious injury.

WARNING: Always wear safety goggles or
safety glasses with side shields when operating
compressor. Failure to do so could result in
objects being thrown into your eyes resulting in
possible serious injury.
CAUTION: Do not use in an environment that is dusty
or otherwise contaminated. Using the air compressor
in this type of environment may cause damage to the
unit.
Using the Air Compressor

WARNING: Always ensure the switch is in the
OFF (O) position and the regulator pressure
gauge reads zero before changing air tools
or disconnecting the hose from the air outlet.
Failure to do so could result in possible serious
personal injury.
● Ensure the tank drain valve  is closed (see Fig. I).
● Ensure the ON/OFF switch  is in the OFF (O) position
and the air compressor is unplugged (see Fig. I).
● Ensure the pressure regulator knob  is turned fully
counterclockwise (see Fig. I).
● If not already installed, attach the hose to the compressor.

● Connect the power cord to the power supply.
● Turn the ON/OFF switch  to the ON (I) position.
● Rotate the pressure regulator knob  to the desired line
pressure. Turning the knob clockwise increases air pressure
at the outlet; turning the knob counterclockwise reduces
air pressure at the outlet.
f NOTE: Before connecting or disconnecting air tools, turn
the regulator knob counterclockwise to stop the flow of air.
● Following all safety precautions in this manual and the
manufacturer's instructions in the air tool manual, you may
now use your air-powered tool.
● If using an inflation accessory with a quick-connect
fitting, control the amount of air flow with the pressure
regulator knob. Turning the knob fully counterclockwise
will completely stop the flow of air.
f NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure
than needed will drain air from the tank more rapidly and
cause the unit to cycle on more frequently.
● When finished, always drain the tank and unplug the unit.
Never leave the unit plugged in and/or running unattended.

WARNING: Check the air tool manual to ensure
the correct air pressure regulator setting for
optimum operation of your air tools. If you
are using an air tool not originally included
in the package contents list (not necessarily
supplied with the air compressor model you
have purchased), your tool may require more
air consumption than this air compressor is
designed to supply. Always read your air tool
owner's manual to match the correct air supply
to your air tool to avoid damage to the tool or
risk of personal injury.
Duty cycle:
To avoid overheating of the electric motor, this compressor
is designed for intermittent operation as indicated on the
dataplate: 5 minutes ON / 5 minutes OFF. This indication is
equivalent to a S3 50% duty cycle: if the compressor run
time exceeds 5 minutes in any 10 minute period, then the
application requires more air than the compressor is capable
to deliver.
