Hazard Potential Consequence Prevention
RIsK of buRns
Serious injury or death could
occur from inhaling gas engine
exhaust which contains carbon
monoxide- a poisonous gas that
can kill you. You CAN NOT smell
or see this gas.
Sprayed materials such as
paint, paint solvents, paint re-
mover, insecticides, weed kill-
ers, etc. contain harmful vapors
and poisons.
Serious injury or death could
occur from inhaling compressed
air. The air stream may contain
carbon monoxide, toxic vapors
or solid particles.
Serious injury could occur from
touching exposed metal parts.
These areas can remain hot for
some time after the air com-
pressor is shutdown.
.
Never us a Gasoline Air Com-
pressor in enclosed or partially-
enclosed spaces. Gasoline Air
Compressors can produce high
levels of carbon monoxide very
quickly. When you use a Gasoline
Air Compressor, remember that
you cannot smell or see carbon
monoxide. Even if you can't smell
exhhaust fumes, you may still be
exposed to carbon monoxide.
If you start to feel sick, dizzy or
weak while using this unit, get
to fresh air right away. Do not
delay. The carbon monoxide from
gasoline engine exhaust can
rapidly lead to full incapacitation
and death.
If you experience serious symp-
toms, get medical attention
immediately. Inform medical staff
that carbon monoxide poisoning
is suspected. If you experienced
symptoms while indoors, have
someone call the re department
to determine when it is safe to
re-enter the effected area.
Operate air compressor only in
a well ventilated area. Follow
all safety instructions provided
with the materials you are spray-
ing. Use of a respirator may be
required when working with some
materials.
Never inhale air from the air com-
pressor either directly or from a
breathing device connected to
the air compressor.
Never allow any part of your
body or other materials to make
contact with any exposed metal
parts on the air compressor.
Never allow any part of your body
to contact the engine mufer or
adjacent areas.

safety RelIef valve: This valve is designed to prevent system failures by reliev-
ing pressure from the system when the compressed air reaches a predetermined level.
The valve is preset by the manufacturer and must not be modied in any way. To verify
the valve is working properly, pull on the ring. Air pressure should escape. When the
ring is released, it will reseat.
PIlot valve: When the toggle is in the upright position, all air from the air com-
pressor is vented through the discharge mufer. This gives an easy start feature.
For normal operation, the toggle is in the 90° position.
aIR IntaKe fIlteR: This lter is designed to clean air coming into the pump. To en-
sure the pump continually receives a clean, cool, dry air supply this lter must always
be clean and ventilation opening free from obstructions. Replace lter element when
necessary.
oIl fIll PoRt/vent: Pour oil into the Oil Fill Port/Vent when required.
oIl sIGht Glass: The Oil Sight Glass displays the oil level in the pump. The oil
level should be at the center of the Oil Sight Glass. If low, add SAE 30W non-deter-
gent oil.
aIR coMPRessoR PuMP: A two stage compressor pump uses two different size cylinders with the intake
valve of the second smaller cylinder linked to the exhaust valve of the rst larger cylinder. On the down
stroke of the large cylinder, air is drawn through the intake valve while the exhaust valve remains closed.
On the upstroke, air is compressed, the intake valve closes and compressed air is forced out through the
exhaust valve, into the inter cooler and through the intake valve of the second smaller cylinder on its down
stroke. On the upstroke of the smaller cylinder, the intake valve closes and the compressed air is com-
pressed a second time and forced out the exhaust valve into the discharge line, through the tank check valve
and into the air tank.
aIR tanK PRessuRe GauGe: The air tank pressure gauge indicates the re-
serve air pressure in the air tank (s).
PRessuRe ReGulatoR: The air pressure coming from the air tank is con-
trolled by the regulator knob. Turn the pressure regulation knob clockwise to
increase discharge pressure, and counterclockwise to decrease discharge pres-
sure.
outlet PRessuRe GauGe: The outlet pressure gauge indicates the air pres-
sure available at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less or equal to the air tank pressure.
aIR tanK DRaIn valve: The drain valve is used to remove moisture from the
air tank(s) after the air compressor is shut off. NEVER attempt to open the drain
valve when more than 10 PSI of air pressure is in the air tank! To open the drain
valve, turn the knob counterclockwise.
