sizes)
GLOSSARY
Become familiar with these terms
before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per
minute; a unit of measure of air
delivery.
PSIG: Pounds per square inch
gauge; a unit of measure of pressure.
Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by OSHA certified
independent safety laboratories and
meet the applicable Underwriters
Laboratories Standards for Safety.
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 the motor will restart
automatically. The low pressure
at which the motor automatically
restarts is called "cut-in" pressure.
Cut-Out Pressure: When an air
compressor is turned on and 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.
Branch Circuit: Circuit carrying
electricity from electrical panel to
outlet.
Refer to the selection chart located on the unit to select the tools this unit is
capable of powering.
• Air Pressure Regulators
• Oil Fog Lubricators
• Air Hose:1/4", 3/8" or 1/2" I.D. in
various lengths
DUTY CYCLE
Air compressors should be operated
on not more than a 50% duty cycle.
This means an air compressor that
pumps air more than 50% of one
hour is considered misuse, because
the air compressor is undersized for
the required air demand. Maximum
compressor pumping time per hour is
30 minutes.

of shock by providing an escape
wire for the electric current. This
air compressor must be properly
grounded.
The portable air compressor is
equipped with a cord having a
grounding wire with an appropriate
grounding plug (see following
illustrations). The plug must be used
with an outlet that has been installed
and grounded in accordance with all
local codes and ordinances.
1. The cord set and plug with this
unit contains a grounding pin.
This plug MUST be used with a
grounded outlet.
IMPORTANT: The outlet being used
must be installed and grounded in
accordance with all local codes and
ordinances.
2. Make sure the outlet being used
has the same configuration
as the grounded plug. DO
NOT USE AN ADAPTER. See
illustration.
3. Inspect the plug and cord before
each use. Do not use if there are
signs of damage.
4. If these grounding instructions
are not completely understood,
or if in doubt as to whether
the compressor is properly
grounded, have the installation
checked by a qualified
electrician.
IMPROPER
GROUNDING CAN
RESULT IN ELECTRICAL SHOCK.

Extension Cords
Use extra air hose instead of an
extension cord to avoid voltage drop
and power loss to the motor, and to
prevent overheating.
If an extension cord must be used,
be sure it is:
• a 3-wire extension cord that has
a 3-blade grounding plug, and a
3-slot receptacle that will accept
the plug on the product
• in good condition
• no longer than 50 feet
• 12 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 10 AWG and 8 AWG
may also be used. DO NOT USE
14 OR 16 AWG.)
Voltage and Circuit Protection
Refer to the Parts Manual for the
voltage and minimum branch circuit
requirements.
Certain air compressors can be
operated on a 15 amp circuit if the
following conditions are met.
1. Voltage supply through branch
circuit is 15 amps.
2. Circuit is not used to supply any
other electrical needs (lights,
appliances, etc.).
3. Extension cords comply with
specifications.
4. Circuit is equipped with a
15 amp circuit breaker or 15
amp time delay fuse. NOTE: If
compressor is connected to a
circuit protected by fuses, use
only time delay fuses. Time delay
fuses should be marked "D" in
Canada and "T" in the US.
If any of the above conditions
cannot be met, or if operation of
the compressor repeatedly causes
interruption of the power, it may be
necessary to operate it from a 20
amp circuit. It is not necessary to
change the cord set.

OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Switch: Turn this
switch "ON/AUTO" to provide
automatic power to the pressure
switch and "OFF" to remove power
at the end of each use.
Pressure Switch: The pressure
switch automatically starts the
motor when the air tank pressure
drops below the factory set "cut-in"
pressure. It stops the motor when
the air tank pressure reaches the
factory set "cut-out" pressure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure available at the outlet side
of the regulator. This pressure is
controlled by the regulator and is
always less than or equal to the tank
pressure.
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controls the air pressure
shown on the outlet pressure
gauge. Pull the knob out and turn
clockwise to increase pressure
and counterclockwise to decrease
pressure. When the desired pressure
is reached push knob in to lock in
place.
Drain Valve:
The drain valve
is located at
the base of the
air tank and is
used to drain
condensation
at the end of each use.

Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the
heart of this cooling system is an
engineered fan. It is perfectly normal
for this fan to blow air through the
vent holes in large amounts. You
know that the cooling system is
working when air is being expelled.
Air Compressor Pump (not
shown): Compresses air into the
air tank. Working air is not available
until the compressor has raised
the air tank pressure above that
required at the air outlet.
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 pressure to remain inside
the air tank.
Air Intake Filter (not shown): This
filter is designed to clean air coming
into the pump. This filter must
always be clean and ventilation
openings free from obstructions. See
"Maintenance".
Check Valve
Before Starting
Break-in Procedure
Serious damage
may result if the
following break-in instructions are
not closely followed.
This procedure is required before the
air compressor is put into service and
when the check valve or a complete
compressor pump has been replaced.
1. Make sure the "On/Auto/Off"
lever is in the "OFF" position.
NOTE: If quick connect is installed,
pull coupler back until it clicks to
prevent air from escaping through the
quick connect.

Air Filter - Inspection and
Replacement
Hot surfaces.
Risk of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
A dirty air filter will not allow the
compressor to operate at full
capacity. Keep the air filter clean at
all times.
1. Remove the air filter and make
sure it is clean.
IMPORTANT: Do not operate
the compressor with the air filter
removed.
Motor
The motor has an automatic reset
thermal overload protector. If the
motor overheats for any reason, the
overload protector will shut off the
motor. The motor must be allowed
to cool down before restarting. The
compressor will automatically restart
after the motor cools.
If the overload protector shuts the
motor off frequently, check for a
possible voltage problem. Low
voltage can also be suspected when:
1. The motor does not get up to full
power or speed.
2. Fuses blow out when starting
the motor; lights dim and remain
dim when motor is started and is
running.
Air Compressor Pump Intake
and Exhaust Valves
Once a year have a Trained Service
Technician check the air compressor
pump intake and exhaust valves.
2. If dirty, rinse air filter with warm
water and squeeze dry.
3. Replace air filter.
NOTE: If the air filter is extremely
dirty it will need to be replaced. Refer
to the Repair Parts for the correct
part number.

STORAGE
Before you store the air compressor,
make sure you do the following:
1. Review the Maintenance section
on the preceding pages and
perform scheduled maintenance
as necessary.
2. Set the "On/Auto/Off" lever to
"OFF".
3. Turn the regulator
counterclockwise and set the
outlet pressure to zero.
4. Remove the air tool or accessory.
5. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately
20 psi. Release safety valve ring.
6. Drain water from air tank by
opening drain valve on bottom of
tank.
Water will
condense in the
air tank. If not drained, water will
corrode and weaken the air tank
causing a risk of air tank rupture.
7. After the water has been drained,
close the drain or drain valve.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, then
reinstalled.
8. Protect the electrical cord and
air hose from damage (such as
being stepped on or run over).
Wind them loosely around the
compressor handle.
Store the air compressor in a clean
and dry location.
