PSI (Pounds per Square Inch)
-
Measurement of the pressure exerted by the force of the air. The actual
PSI output is measured by a pressure gauge on the compressor.
SCFM (Standard Cubic Feet per Minute) - Sometimes called CFM (Cubic Feet per Minute). Measurement
of air volume delivered by the compressor.
Air Delivery - A combination of PSI and SCFM. The air delivery required by a tool is stated as (number)
SCFM at (number) PSI. The combination of these figures determines what size unit is needed.
Air Tank Capacity - The volume of air stored in the tank and available for immediate use. A large tank
allows the intermittent use of an air tool with an air requirement higher than the compressor’s rated
delivery.
Amps or Amperage - A measure of the electrical force minus the resistance on an electrical line. This air
compressor requires 15 amps for operation. Be sure the compressor will operate on an electrical line with
the proper amps. If other appliances operate on the same line, they will reduce the available amps. If the
amperage is not adequate, the result will be blown fuses or tripped circuits.
Volts or Voltage - A measurement of the force of an electrical current.
Cut-in / Cut-off Pressure - Specific PSI at which a compressor starts and stops while refilling the air tank.
Regulator - The regulator controls the amount of air pressure at the hose outlet. Turning regulator knob
clockwise (to the right) will increase air pressure at the outlet. Turning knob counterclockwise (to the
left) will lower air pressure to the outlet. Turning knob fully counterclockwise will shut off flow of air
completely.
Handle - Designed to move the compressor.
ASME Safety Valve - This valve automatically releases air if the tank pressure exceeds the preset
maximum.
Exhaust Tube - This tube carries compressed air from the pump to the check valve. This tube becomes very
hot during use. To avoid the risk of severe burns, never touch the exhaust tube.
Check Valve - One-way valve that allows air to enter the tank, but prevents air in the tank from flowing
back into the compressor pump.
Air Outlet - A quick connect coupler designed to work in combination with a quick connect plug to quickly
and easily join the compressor to an air hose.

MOTOR SPECIFICATIONS AND ELECTRICAL REQUIREMENTS
Power Supply and Motor Specifications
To reduce the risk of electrical hazards, fire hazards or damage to the tool, use proper circuit
protection.
INSTALLATION
Your tool is wired at the factory for operation using the voltage shown. Connect tool to a
power line with the appropriate voltage and a 15-amp branch circuit. Use a 15-amp time delay
type fuse or circuit breaker.
To reduce the risk of shock or fire, if power cord is worn or cut, or damaged in any way, have it
replaced immediately.
The A-C motor used on this compressor is a permanent split capacitor non-reversible induction type, having
the following specifications. It is wired at the factory for operation on 120V AC, 60 Hz service.
WARNING: Risk of electric shock. Use GFCI. Use indoors only. Disconnect all connections before
servicing. Use identical replacement parts. Servicing must be performed by a licensed, qualified
electrician.
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical
current to reduce the risk of electric shock. This compressor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug, as shown. The plug must be plugged into a
matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.
If the grounding instructions are not completely understood, or if you are in doubt as to whether the
compressor is properly grounded check with a qualified electrician or service personnel.
Grounding Instructions
1. This product is for use on a nominal 120 v circuit.
It must be grounded. In the event of an electric
short circuit, grounding reduces the risk of
electrical shock by providing an escape wire for
the electric current. Unit is equipped with a cord
that has a grounding prong. It will fit one of the
common outlet types shown in Figure 2. If plug
will not fit in the desired outlet, have the plug
or the outlet replaced by a qualified electrician.
WARNING: Risk of electric shock.
Improper use of grounding
plug can result in a risk of electrical shock. Plug must
be plugged into an outlet that is properly installed and
grounded in accordance with local codes and ordinances

2. Always check with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in 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 qualified electrician.
3. Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that
accepts the plug on the product. Make sure your extension cord is not damaged. When using an
extension cord, be sure to use one heavy enough to carry the current your product draws. For lengths
less than 25ft. 16-3 AWG extension cords shall be used. An undersized cord results in a drop in the
voltage and loss of power and overheating. (NOTICE: Table 1 shows the correct size to use depending
on cord length. When in doubt, use the next heavier gauge. The smaller the gauge number, the
heavier the cord.)
4. Use of an extension cord may cause excess heat to motor. This could lead to tripped breaker (at
electrical panel) or tripped thermal overload (on compressor motor). If this occurs, eliminate extension
cord and plug compressor directly into electrical outlet. Avoid using extension cords; use longer air
hose(s) instead.
If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal.
The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.
