Glossary of Terms

ASME Safety Valve
A safety valve that automatically releases
the air if the air receiver (tank) pressure
exceeds the preset maximum.
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.
Unpacking and Checking Contents
1. Remove the air compressor from the
carton.
2. Place the compressor on a secure,
stationary work surface and look it
over carefully.
Do not operate unit if damaged
during shipping, handling or
use. Damage may result in
bursting and cause injury or
property damage.
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.
Regulator
A control that adjusts the line pressure to
the proper amount needed to operate
spray guns and air tools.
Tank Pressure Gauge
Indicates tank pressure in psi.
Line Pressure Gauge
Displays the current line pressures. It is
regulated by the regulator knob.
Cut-in/Cut-off Pressure
Specific psi at which a compressor starts
and stops while refilling the air tank.
For your own safety, never
operate unit until all assembly
steps are complete and until
you have read and understood
the entire operator's manual.
To reduce the risk of injury, if
any parts are missing, do not
attempt to assemble the air
compressor until the missing
parts are obtained and installed
correctly.
