WARNING:

ASME Safety Valve

A safety valve that automatically releases the air if the
tanks’ 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 tanks and available for
immediate use. Large tanks allow 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 electrical 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.

Tanks Pressure Gauge

Indicates pressure of the air tanks in psi.

Regulated Outlet 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 tanks.

universal-style quick connect fittings and allow rapid
tool changes.

2. Regulated Outlet Gauge. This gauge shows

at-a-glance, air pressure at outlet. Air pressure is
measured in pounds per square inch (PSI). Most
tools have maximum pressure ratings. Never exceed
the maximum pressure rating of the tool you are
using. Be sure this gauge reads ZERO before
changing air tools or disconnecting hose from outlet.

3. Handle. Used to move the compressor.

4. Regulator Knob. This knob controls air pressure to

an air operated tool or paint spray gun. Turning the
knob clockwise increases air pressure at the outlet.
Turning counterclockwise will lower air pressure at
the outlet. Fully counterclockwise will shut off the
flow of air completely.

OPENCLOSE

5. Tank Pressure Gauge. Gauge shows pressure in

tank indicating compressor is building pressure
properly.

6. Pump. The pump takes in air and generates the
pressurized air in the air storage tanks.

7. ASME Safety Valve. This valve automatically
releases air if the tank pressure exceeds the preset
maximum.

8. On/Off Switch. This switch allows manual control of
the compressor. Note that when the switch is turned
on, the compressor will automatically start and stop
depending on tank pressure.

9. Tank Drain Valve. The tank drain valve allows
moisture to be removed from the tanks.

10. Air Storage Tanks. The tanks store air for later use.

Operating Your Air Compressor

WARNING:

Moisture in Compressed Air

Moisture in compressed air will form into droplets as it
comes from an air compressor pump. When humidity is
high or when a compressor is in continuous use for an
extended period of time, this moisture will collect in the
tanks. When using a paint spray or sandblast gun, this
water will be carried from the tanks through the hose,
and out of the gun as droplets mixed with the spray
material.

Operating Your Air Compressor

Make sure the tank drain valve is closed, the regulator
knob is turned fully counterclockwise, and the On/Off
switch is in the Off position.

Plug compressor into a dedicated 15 Amp (minimum)
circuit.

Turn On/Off switch to the On position. The compressor
will now start building pressure.

After compressor reaches cut-off pressure, install a hose
(with the desired air tool attached) into the outlet fitting.

IMPORTANT: This condensation will cause water spots
in a paint job, especially when spraying other than water
based paints. If sandblasting, it will cause the sand to
cake and clog the gun, rendering it ineffective.

A filter in the air line, located as near to the gun as
possible, will help eliminate this moisture.

Adjust the regulator knob to the desired pressure.
The compressor is now ready to operate.

!

Do not over-pressurize any air tool. Consult air
tool instructions for proper air tool pressure.

For Trouble-Free Operation

1. Read instructions: Carefully read through this
operator’s manual BEFORE OPERATING the new air
compressor. It contains information about operation
and maintenance of the unit.

2. Drain tanks daily: Depressurize system prior to
draining tanks by manually releasing air from the
safety valve. Open tank drain valve and drain
moisture from tank. This helps keep oil and moisture
out of the compressed air system. Be sure to close
tank drain valve tightly before operating compressor.

10

Maintenance

WARNING:

DANGER:

WARNING:

!

Release all pressure and disconnect power before
making any repair.
