Motor Specifications and
Electrical Requirements (continued)
Thermal Overload Protector
!CAUTION:
This compressor is equipped with an automatic reset thermal overload protector which will shut off motor if it becomes overheated.
If thermal overload protector shuts motor OFF frequently look for the following causes.
1.Low voltage.
2.Wrong gauge wire.
3.Clogged air filter.
4.Lack of proper ventilation.
5.Unit is being used with an extension cord.
See Troubleshooting Chart for corrective action.
!CAUTION:
The motor must be allowed to cool down before
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.
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.
Volts or Voltage
A measurement of the force of an electri- cal current.
Amps or Amperage
A measure of the electrical force minus the resistance on an electrical line. RIDGID air compressors require 15 amps for operation. Be sure the com- pressor 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 amper- age is not adequate, the result will be blown fuses or tripped circuits.
