DANGER  
Gasoline vapor is highly flam-  
mable. Refill outdoors or only in  
well ventilated areas. Do not  
store, spill or use gasoline near  
an open flame or heat devices  
such as a stove, furnace, or  
water heater, which utilize a  
pilot light, or any device that  
can create a spark. If gasoline  
is accidentally spilled, move  
unit away from the spill area  
and avoid creating any source  
of ignition until gasoline vapors  
have dissipated.  
!
DANGER  
14. Do not tamper with governor setting  
on engine. Overspeeding the unit  
severely shortens engine life and may  
also be very hazardous.  
Breathable Air Warning  
This compressor/pump is not equipped and should not be used “as  
is” to supply breathing quality air. For any application of air for  
human consumption, the air compressor/pump will need to be fitted  
with suitable in-line safety and alarm equipment. This additional  
equipment is necessary to properly filter and purify the air to meet  
minimal specifications for Grade D breathing as described in  
Compressed Gas Association Commodity Specification G 7.1 - 1966,  
OSHA 29 CFR 1910. 134, and/or Canadian Standards Associations  
(CSA).  
!
DANGER  
Never attempt to  
repair or modify a  
tank! Welding, drilling  
or any other modification will  
weaken the tank resulting in  
damage from rupture or explo-  
sion. Always replace worn or  
damaged tanks.  
DISCLAIMER OF WARRANTIES  
In the event the compressor is used for the purpose of breathing air  
application and proper in-line safety and alarm equipment is not  
simultaneously used, existing warranties shall be voided, and  
Campbell Hausfeld disclaims any liability whatsoever for any loss,  
personal injury or damage.  
!
WARNING  
Motors, electrical  
equipment and con-  
trols can cause electrical arcs  
that will ignite a flammable gas  
or vapor. Never operate or  
15. Tanks rust from moisture build-up,  
which weakens the tank. Make sure to  
drain tank daily and inspect periodical-  
ly for unsafe conditions such as rust  
formation and corrosion

Glossary of Terms  
ASME Safety Valve  
Amps or Amperage  
Warning Labels  
A safety valve that automatically releases A measure of the electrical force minus  
the air if the air receiver (tank) pressure  
exceeds the preset maximum.  
Find and read all warning labels found on  
the air compressor shown below  
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.  
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.  
Regulator  
A control that adjusts the line pressure to  
the proper amount needed to operate  
spray guns and air tools.  
Air Delivery  
Tank Pressure Gauge  
Indicates tank pressure in psi.  
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.  
Line Pressure Gauge  
Displays the current line pressures. It is  
regulated by the regulator knob.  
Air Tank Capacity  
Cut-in/Cut-off Pressure  
The volume of air stored in the tank and  
Specific psi at which a compressor starts

When maximum tank pressure is  
reached, the compressor automatically  
unloads, bringing the engine to idle. The  
engine remains at idle until tank pressure  
falls to a preset level. The engine then  
accelerates and the compressor pumps  
additional air into the tank.  
With engine OFF, clean debris from  
engine, flywheel, tank, air lines and  
pump cooling fins.
