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.
WHAT TO
LOOK FOR
Hot Parts
WHAT COULD HAPPEN
The metal compressorcomponents,such as mani-
fold, tubes, etc., become hotwhenthe aircompressor
isrunning. If you touch them, you may be seriously
burned.
IMPORTANT SAFETY INFORMATION -
A HAZARD THAT MIGHTCAUSE
SERIOUS INJURY OR LOSS OF LIFE.
NOTE
information that you should pay special
attention to.
HOW TO PREVENT IT
Avoid contact with metal components ofthe compres-
sor during or immediately after operation, Reaching
under or removing portions of the plastic enclosures
such as the filter cover and console cover exposes hot
surfaces. Attowcompressor to cool prior to servicing.
Flammable
Vapors
Air Tank
It is normal forthe motorandpressure switchto spark
when compressorstartsor stops.A spark can ignite
vapors from gasolineor 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.
Incompatability between tank and compressor will
cause the tank to rupture.
Modifications to the airtankwill cause ittc 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, freeofgasolineorothersolventvapors. 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 weld or in any way modify the air tank.
Thetankmay rupture or explode. Ifleaks deve op due
to corrosion or tank is damaged, return to Authorized
Service Center for replacement.

WHAT TO
LOOK FOR
SAFETY GUIDELINES
WHAT COULD HAPPEN
HOW TO PREVENT IT
Compressed
Air
Electricity
Compressed aircan propel dust, dirtor loose particles
it comes in contact with. These propelled particles
may cause serious injury or damage.
Too much air pressure appliedto air toolsor acces-
soriescan cause damage or riskofbursting.
Your air compressor is powered by electricity. Like
any other electrically powered device, if it is not used
properly it may cause electrical shock.
Neverpointany nozzleor sprayertowarda personor
any partof the body.
Alwayswear safetygogglesorglasseswhenusingthe
air compressor.
Always turnthe air compressoroffb_ore attachingor
removing accessories.
Check the manufacturer's pressure rating for air
tools and accessories. Regulator outl_ 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 compressorprior to mainte-
nance or repair.
Never use the air compressoroutdoorswhen 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 compressedair to contain toxic or
irritatingvapors. Suchvapors are harmfulif inhaled.
Certain materials you are spraying (like paint,weed
killer, sandor insecticide)canbe harmfulifyouinhale
them.
The solvents1,1,1 - Trichloroethaneand Methylene
Chloddecanchemicallyreectwithaluminumusedin
)aint spray guns, paint pumps, etc., and cause an
explosion.Thesesolventscan alsoreact withgalva-
nizedcomponentsand cause corrosionand weaken-
ingof parts. This doesnotaffectyourair compressor
- butit may affectthe equipmentbeing used.
Never directlyinhalethe compressedairproducedby
this unit.
Readlabels and safetydatafor allmaterialsyouspray.
Followall safety precautions.
Use a mask or respirator ifthera isa chance of inhaling
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 a safety expert orindustrial hygienist ifyou are not
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 parts.
You must either change the material you intend to
spray, or use only stainless steel spray equipment.

GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubicfeet per minute; a unit of measure
of air delivery.
PSIG: Pounds per square inchgauge; a unit ofmeasure
of pressure.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
U.L. Listed: This product is Listed by UndenNriters
Laboratories, Inc. (UL). Samples of this product have
been evaluated by UL and meet the applicable UL Stan-
dards for Safety.
Cut-In Pressure: While the motor isoff, air tank pressure
drops as you continue to use your accessory. When the
tank pressure drops to a certain low level the motor will
restart automatically. The low pressure at which the
motorautomatically re-starts is called =cut-in pressure."
Cut-Out Pressure: When you turn onyour air compres-
sorand itbegins to run, air pressure inthe airtank begins
to build. It builds to a certain high pressure before the
motor automatically shuts off - protecting your air tank
from pressure higherthan its capacity. The high pressure
at which the motor shuts off is called =cut-out pressure."
