IF SPRAYING FLAMMABLE MATERIALS, LOCATE COMPRES-
SOR AT LEAST 20 FEET AWAY FROM SPRAY AREA. AN
ADDITIONAL LENGTH OF HOSE MAY BE REQUIRED.
STORE FLAMMABLE MATERIALS IN A SECURE LOCATION
AWAY FROM COMPRESSOR.
NEVER PLACE OBJECTS AGAINST OR ON TOP OF COM-
PRESSOR. OPERATE COMPRESSOR IN AN OPEN AREA AT
LEAST 12 INCHES AWAY FROM ANY WALL OR OBSTRUC-
TION THAT WOULD RESTRICT THE FLOW OF FRESH AIR TO
THE VENTILATION OPENINGS.

HOW TO PREVENT IT
.s,o ou,s..o]
A/_: THE FOLLOWING CONDITIONS COULD LEAD TO A WEAKENING OF THE TANK, AND RESULT IN A
VIOLENT TANK EXPLOSION AND COULD CAUSE PROPERTY DAMAGE OR SERIOUS INJURY.
WHAT CAN HAPPEN
1. FAILURE TO PROPERLY DRAIN CONDENSED WATER
FROM THE TANK, CAUSING RUST AND THINNING OF THE
STEEL TANK.
2. MODIFICATIONS OR AI_EMPTED REPAIRS TO THE TANK.
3. UNAUTHORIZED MODIFICATIONS TO THE UNLOADER
VALVE, SAFETY VALVE, OR ANY OTHER COMPONENTS
WHICH CONTROL TANK PRESSURE.
4. EXCESSIVE VIBRATION CAN WEAKEN THE AIR TANK
AND CAUSE RUPTURE OR EXPLOSION.
DRAIN TANK DAILY OR AFTER EACH USE. IF TANK DEVEL-
OPS A LEAK, REPLACE IT IMMEDIATELY WITH A NEW TANK OR
REPLACE THE ENTIRE COMPRESSOR.
NEVER DRILL INTO, WELD, OR MAKE ANY MODIFICATIONS
TO THE TANK OR ITS ATTACHMENTS.
THE TANK IS DESIGNED TO WITHSTAND SPECIFIC OPERATING
PRESSURES. NEVER MAKE ADJUSTMENTS OR PARTS
SUBSTITUTIONS TO ALTER THE FACTORY SET OPERATING
PRESSURES.
HOW TO PREVENT IT
ATTACHMENTS &ACCESSORIES:
EXCEEDING THE PRESSURE RATING OF AIR TOOLS, SPRAY
GUNS, AIR OPERATED ACCESSORIES, TIRES AND OTHER
INFLATABLES CAN CAUSE THEM TO EXPLODE OR FLY
APART, AND COULD RESULT IN SERIOUS INJURY.
FOR ESSENTIAL CONTROL OF AIR PRESSURE, YOU MUST
INSTALL A PRESSURE REGULATOR AND PRESSURE GAUGE
TO THE AIR OUTLET OF YOUR COMPRESSOR. FOLLOW THE
EQUIPMENT MANUFACTURERS RECOMMENDATION AND
NEVER EXCEED THE MAXIMUM ALLOWABLE PRESSURE
RATING OF ATTACHMENTS. NEVER USE COMPRESSOR TO

Youhave purchasedan air compressorunitconsisting
of analuminum 2cylinder,single-stageair compressor
pump (with cast ironsleeves), an air tank, wheels,
handle,associated controls and instruments.
Your air compressor can be used for operating paint
spray guns, air tools, caulking guns, grease guns, air
brushes, sandblasters, inflating tires and plastic toys,
spraying weed killers, insecticides, etc. An air pres-
sure regulator is required for most of these applica-
tions.
An air line filter is usually required for removal of
moisture and oil vapor in compressed air when a paint
spray gun is used.
An in-line lubricator is usually required for air tools to
prolong tool life.
Separate air transformers which combine the functions
of air regulation and/or moisture and dirt removal
should be used where applicable.
CFM: Cubic Feet per Minute.
SCFM: Standard Cubic Feet per Minute; a unit of
measure of air delivery.
PSI: Pounds per Square Inch; a unit of measure of
pressure.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
Cut-In Pressure: While the motor is off, air tank
pressure drops as you continue to use your accessory.
When the tank pressure drops to a certain low level
and the pressure switch lever is in "Auto", the motor
willrestart automatically. The low pressure at which
the motor automatically restarts iscalled "cut-in
pressure."

Cut-Out Pressure: When you turn on your air com-
pressor 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 its capacity.
The high pressure at which the motor shuts off is
called "cut-out pressure."
CSA: Electrical products sold in Canada are required
to be certified to the applicable CSA standard (s).
Canadian Standards Association (CSA) is a standards
writing and safety testing organization. Products that
are CSA certified have been evaluated and tested and
found to meet or exceed the applicable CSA standard
(s) for safety and electrical performance.
021245 Rev. 0 6/29/00 6 -- ENG
Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke,
air is drawn in through the air intake valves. The exhaust
valves remain closed. On the upstroke of the piston, air
is compressed. The intake valves close and compressed
air is forced out through the exhaust valves, through the
outlet tube, through the check valve and into the air tank.
Check Valve: When the air compressor is operating, the
check valve is "open", allowing compressed air to enter
the air tank. When the air compressor reaches "cut-out"
pressure, the check valve "closes", allowing air pres-
sure to remain inside the air tank.
Pressure Switch; The pressure switch is fitted with a
small lever. It is labeled "Auto/O" for automatic run or
off. In the "O" position, the motor will not run. In the "Auto"
position, it automatically starts the motor when the air
tank pressure drops below the factory set "cut-in" pres-
sure. It stops the motor when the air tank pressure reaches
the factory set "cut-out" pressure.
Pressure Release Valve: The pressure release valve lo-
cated on the side of the pressure switch is designed to
automatically release compressed air trapped within the
compressor head and outlet tube. This short release of
air will occur when the air compressor reaches "cut-out"
pressure or the unit is shut off. If the air is not released,
the motor will not be able to start when next required.
Flow Valve: The flow valve allows air to flow from the
head as the motor is getting "up to speed". Once the
motor reaches normal operating speed, the flow valve
closes and the pump begins to compress air, thus re-
quiring less amp draw on initial start.
Regulator: The air pressure coming from the air tank is
controlled by the regulator. The regulator control knob is
a vibration proof design. Lift the regulator knob to en-
gage and depress the knob to lock. Turn the regulator
knob clockwise to increase pressure and counter-clock-
wise to decrease pressure. To avoid minor readjustment
after making a change in pressure setting, always ap-
proach the desired pressure from a lower pressure. When
reducing from a higher to a lower setting, first reduce to
some pressure less than that desired, then bring up to
the desired pressure. Depending on the air requirements
of each particular accessory, the outlet regulated air pres-
sure may have to be adjusted while operating the acces-
sory.
Regulator Gauge: The outlet pressure gauge indicates
the air pressure available at the outlet side of the regula-
tor. This pressure is controlled by the regulator and is
always less than or equal to the tank pressure. See "Op-
erating Procedures".
Tank Pressure Gauge: The tank pressure gauge indi-
cates the reserve air pressure in the tank.
Air Intake Filter: This filtei is designed to clean air coming
into the pump. This filter must always be clean and ventila-
tion openings free from obstructions. See "Maintenance".
Drain Valve: This valve is located at the bottom of the
tank. To drain accumulated moisture from the tank, pull
on the safety valve until tank pressure is 15 PSI. Un-
screw the drain valve and allow the water to drain.
Safety Valve: If the pressure switch does not shut off the
air compressor at its cut-out pressure setting, the safety
valve will protect the tank against high pressure by "pop-
ping out" at its factory set pressure (slightly higher than
the pressure switch cut-out setting).
