PARTS DESCRIPTION
2
A. Electric Motor
The motor is used to power the pump.
B. Air Compressor Pump
The pump is used to compress the air and discharge it into the tank via
the piston moving up and down in the cylinder.
C. Safety Valve
This valve is used to prevent system failure by reducing pressure from the
system when it reaches a preset level if the ON/OFF switch has not shut
down the motor. It will pop open automatically, or it can be activated
manually by pulling the ring on the valve.
D. ON/OFF Switch
This switch turns on the compressor and is operated manually. When in
the ON position, it allows the compressor to start up or shut down
automatically, without warning, upon air demand. ALWAYS set this switch
to OFF when the compressor is not being used, and before unplugging
the compressor.
E. Air Pressure Regulator
The regulator is used to adjust the pressure inside the line to the tool that
is being used. Turn the knob clockwise to increase the pressure and
counterclock-wise to decrease the pressure.
F. Tank Pressure Gauge
The gauge is used to measure the stored air pressure level of the tank. It is
not adjustable by the operator and does not indicate line pressure.
G. Outlet Pressure Gauge
The gauge measures the regulated outlet pressure.
H. Quick Coupler
The quick coupler is connected to a quick connector and is used for
connecting an air hose.
I. Drain Valve
The drain valve is used to remove moisture from the air tank after
the unit is shut off.
J. Air Tank
The tank is used to store the compressed air.
K. Power Cord
This product is for use on a nominal 120-volt circuit and should be
grounded. A cord with a grounding plug must be used. Make sure the
product is connected to an outlet having the same configuration as the plug
(see Figure 1). No adapter should be used with this product.
Check with a licensed electrician if the grounding instructions are not
understood or there is doubt as to whether the product is properly
grounded. Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a licensed electrician.
Improper installation of the grounding plug will
result in a risk of electric shock.
If repair or replacement of the cord or plug is
necessary, do not connect the grounding wire to
either at blade terminal. The grounding wire is in
the green outer surface.

GENERAL SAFETY INFORMATION
The manufacturer cannot possibly anticipate every possible circumstance
that might involve a hazard. The warnings in this manual, and the tags and
decals affixed to the unit are, therefore, not all-inclusive. If you use a
procedure, work method, or operating technique that the manufacturer
does not specifically recommend, you must satisfy yourself that it is safe
for you and others. You must also make sure that the procedure, work
method, or operating technique that you choose does not render the
compressor unsafe.
The safety alert symbol indicates a potential hazard to personal injury. A signal
word (DANGER, WARNING, or CAUTION) is used with the alert symbol to
designate a degree or level of hazard seriousness. A safety symbol may be
used to represent the type of hazard. The signal word NOTICE is used to address
practices not related to personal injury.
