Thermal Overload Protector

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.

This compressor is equipped

with an automatic reset thermal

overload protector which will

shut off motor if it becomes

overheated.

!

CAUTION:

The motor must be allowed to

cool down before start-up is

possible. The motor will auto-

matically restart without warn-

ing if left plugged into electrical

outlet, and the motor is turned

on.

!

CAUTION:

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 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.

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.
