Code Certification: Products that
bear one or more of the following
marks: UL, CUL, ETL, CETL, have
been evaluated by ©SHA 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 auto-
matically. The low pressure at which
the motor automatically restarts is
called "cut-in" pressure.
Cut-Out Pressure: When an air com-
pressor 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 automati-
cally 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.

GROUNDING INSTRUCTIONS
_Risk of Electrical
Shock. In the event
of a short circuit, grounding reduces
the risk 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).
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.
4.
Inspect the plug and cord before
each use. Do not use if there are
signs of damage.
If these grounding instructions are
not completely understood, or if in
doubt as to whether the compres-
sor is properly grounded, have the
installation checked by a qualified
electrician.
Risk of Electrical
Shock. iMPROPER
GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.
Do not modify the plug provided, if
it does not fit the available outlet, a
correct outlet should be installed by
a qualified electrician.
Repairs to the cord set or plug
MUST be made by a qualified elec-
trician.
N014212 10-ENG

Extension Cords
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
14 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 12 AWG and 10 AWG
may also be used. DO NOT USE
16 OR 18 AWG.)
The use of an
-- undersized
extension cord will cause voltage to
drop resulting in power loss to the
motor and overheating. Instead of
using an extension cord, increase
the working reach of the air hose by
attaching another length of hose to its
end. Attach additional lengths of hose
as needed.
Voltage and Circuit Protection
Refer to the specification chart for the
voltage and minimum branch circuit
requirements.
Risk of Opertion.
-- Certain air
compressors can be operated on
a 15 amp circuit if the following
conditions are met.
1. Voltage supply to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electrical needs.
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 compres-
sor 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.

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.
Safety Valve
Description of Operation
Become familiar with these controls
before operating the unit.
On(I)/Off(O) Switch: Place this switch
in the On (I) position to provide
automatic power to the pressure
switch and Off (O) to remove power at
the end of each use.
Pressure Switch (not shown): 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).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
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.
Regulator: Controls the air pressure
shown on the outlet pressure
gauge. Turn regulator knob
clockwise to increase pressure
and counterclockwise to decrease
pressure.
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.
Drain Valve:
The drain valve
is located at Drain
the base of the Valve
air tank and is
used to drain
condensation at the end of each use.
N014212 12-ENG

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.
Motor Overload Protector (not
shown): 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.
