SAFETY GUIDELINES
This manual contains information that is important for you to know and understand. This information relates to
protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information,
we use the following symbols. Please read the manual and pay attention to these sections.
URGENT SAFETY INFORMATION - A
HAZARD THAT WILL CAUSE
SERIOUS INJURY OR LOSS OF LIFE.
Information for preventing damage to
equipment.
HAZARDS CAN OCCUR IF EQUIPMENT IS NOT USED PROPERLY.
PLEASE READ THE FOLLOWING CHART.

IMPORTANT SAFETY INFORMATION -
A HAZARD THAT MIGHT CAUSE
SERIOUS INJURY OR LOSS OF LIFE.
NOTE
Information that you should pay special
attention to.
HOW TO PREVENT IT
Avoid contact withmetal components ofthe compressor
during or immediately after operation. Reaching under or
removing portions of the plastic enclosures such as the
console cover exposes hot surfaces. Allowcompressorto
cool prior to servicing.
Flammable
Vapors
Air Tank
It isnormal for the motor and pressure switch to spark
when compressor starts or stops. A spark can ignite
vapors from gasoline or solvents, causing a fire or
explosion.
Modifications to air compressor components in an
attempt to reach higher air pressure can cause the air
tank to rupture or explode.
Incomparability between tank and compressor will
cause the tank to rupture.
Modifications to the airtank will cause it to weaken.
If spraying a flammable material, provide ample ven-
tilation. Never spray in a closed area. There must be
a flow of fresh air at all times.
Always operate the air compressor in well-ventilated
areas, free of gasoline or other solvent vapors. Do not
operate the compressor near the spray area.
Do not adjust, remove or tamper with the safety valve
or pressure switch. If safety valve or pressure switch
replacement is necessary, a part with the same ratings
must be used.
Never replace the air tank with a different model or a
larger tank. Return to Authorized Service Center if
replacement is required.
Never drill into weldor in anyway modify theairtank.
Thetank may rupture or explode. Ifleaks deveop due
tocorrosion or tank is damaged, return to Authorized
Service Center for replacement.
SAFETY GUIDELINES
WHAT TO
LOOK FOR WHAT COULD HAPPEN HOW TO PREVENT IT
Compressed
Air
Electricity
Compressed air can propel dust, dirt or loose particles
it comes in contact with. These propelled particles
may cause serious injury or damage.
Too much air pressure applied to air tools or acces-
sories can cause damage or risk of bursting.
Your air compressor is powered by electricity. Like
any other electrically powered device, ifit is not used
properly it may cause electrical shock,
Never point any nozzle or sprayer toward a personor
any part of the body.
Alwayswear safetygoggles or glasseswhen usingthe
air compressor.
Alwaysturn the aircompressoroffbefore attachingor
removing accessories.
Check the manufacturer's pressure rating for air
tools and accessories. Regulator outlet pressure
must never exceed the maximum pressure rating.
NOTE: IF A REGULATOR IS NOT SUPPLIED
WITH YOUR COMPRESSOR, YOU MUST
INSTALL ONE BEFORE USING AIR TOOLS AND
ACCESSORIES WITH PRESSURE RATINGS
LESS THAN 200 PSIG.
Always unplug the air compressor prior to mainte-
nance or repair.
Never use the air compressor outdoors when it is
raining.
Always plug the cord into an electrical outlet with the
specified voltage and adequate fuse protection.
Toxic Vapors
Unsuitable
Solvents
It is normal for compressed air to contain toxic or
irritating vapors, Such vapors are harmful if inhaled.
Certain materials you are spraying (like paint, weed
killer, sand or insecticide) can be harmful ifyou inhale
them.
The solvents 1,1,1 - Trichloroethane and Methylene
Chloride can chemically react with aluminum used in
paint spray guns, paint pumps, etc., and cause an
explosion. These solvents can also react with galva-
nized components and cause corrosion and weaken-
ing of parts. This does not affect your air compressor
- but it may affect the equipment being used.
Never directly inhale the compressed air produced by
this unit.
Readlabels and safety datafor allmaterialsyouspray.
Follow all safety precautions.
Use amask or respirator ifthere isachanceofinhaling
toxic sprayed materials. Masks and respirators have
limits and will only provide protection against some
kinds and limited amounts of toxic material. Read
mask and respirator instructions carefully. Consult
with asafety expert or industrial hygienist ifyou arenot
sure about the use of a certain mask or respirator.
Ifthe material you intend to spray contains the solvents
listed at left (read the label or data sheet), do not use
accessories that contain aluminum or galvanized pads.
You must either change the material you intend to
spray, or use only stainless steel spray equipment.
GLOSSARY
CFM: Cubicfeet per minute.
SCFM: Standard cubic feet per minute; a unit of measure
of air delivery.
PSlG: Pounds per square inch gauge; a unit of measure
of pressure.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
U.L. Listed: This productis Listed by Underwriters Labora-
tories, Inc. (UL). Samples of this product have been evalu-
ated by UL and meet applicable UL Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure
drops as you continue to use youraccessory.When thetank
pressure drops to a certain low level the motor will restart
automatically. The low pressure atwhich the motor automat-
ically re-starts is called "cut-in pressure."
Cut-Out Pressure: When you turn on your air compres-
sor and it begins to run, air pressure in the air tank begins
to build. It builds to a certain high pressure before the
motor automatically shuts off - protecting your air tank
from pressure higher than itscapacity. The high pressure
at which the motor shuts off is called "cut-out pressure."
