WARNING: Risk of Bursting
Air Tank: The following conditions could lead to a weakening of the tank, and result
in a violent tank e×plosion and could cause property damage or serious injury.
What Could Happen
Failure to properly drain condensed
water from tank, causing rust and
thinning of the steel tank.
Modifications or attempted repairs to
the tank.
Unauthorized modifications to the
unRoader valve, safety valve, or any
ether components which eontrom tank
pressure.
Excessive vibration can weaken the
air tank and cause rupture or
explosion
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.
Now To Prevent It
Drain tank daily or after each use. If tank
develops 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.
For essential control of air pressure, you
must install a pressure regulator and
pressure gauge to the air outBet (if not
equipped} of your compressor. Follow the
equipment manufacturers recommendation
and never exceed the maximum allowable
pressure rating of attachments. Never use
compressor to inflate small low
pressure objects such as children's
toys, footballs, basketballs, etc.
WARNING: Risk from Flying Objects
What Coumd Happen How To Prevent It
The compressed air stream can cause
soft tissue damage to exposed skin and
can propel dirt, chips, loose particles,
and small objects at high speed,
resulting in property damage or personal
injury.
Always wear ANSI Z87.1 approved
safety gmasses with side shields when
using the compressor.
Never point any nozzle or sprayer
toward any part of the body or at other
people or animals.
Always turn the compressor off and
bleed pressure from the air hose and tank
before attempting maintenance, attaching
tools or accessories.

WARNING: Risk of Electticam Shock
What CouBd Happen
Your air compressor is powered by
eRectricity, Like any other electrically
powered device, If it is not used
property it may cause eRectric shock.
Repairs attempted by unqualified
personneB can result in serious injury
or death by electrocution.
Electrical Grounding: Failure to provide
adequate grounding to this product
could result in serious injury or death
from electrocution.
See grounding instructions.
Now 3"o Prevent it
Never operate the compressor outdoors
when it is raining or in wet conditions.
Never operate compressor with
protective covers removed or damaged.
Any electricam wiring or repairs required
on this product should be performed by
authorized service center personnel in
accordance with national and local
electrical codes.
Make certain that the electrical circuit
to which the compressor is connected
provides proper eBectrical grounding,
correct voltage and adequate fuse
protection.
WARNING: Risk to Breathing
What Could
The compressed air directly from your
compressor is not safe for breathing.
The air stream may contain carbon
monoxide, toxic vapors, or solid
particles from the tank. Breathing these
contaminants can cause serious injury
or death.
Sprayed materials such as paint, paint
solvents, paint remover, insecticides,
weed killers, may contain harmful
vapors and poisons.
Now To Prevent It
Air obtained directly from the compressor
shouM never be used to supply air for
human consumption. In order to use air
produced by this compressor for
breathing, suitable filters and in-line
safety equipment must be property
installed. In-line filters and safety
equipment used in conjunction with the
compressor must be capabBe of treating
air to aH appBicable local and federam
codes prior to human consumption.
Work in an area with good cross
ventilation. Read and follow the safety
instructions provided on the label or
safety data sheets for the materiaBs
you are spraying. Use a NmOSH/MSHA
approved respirator designed for use
with your specific application.

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. inspect the plug and cord before
each use. Do not use if there are
signs of damage.

Extension Cords
Using extension cords is not
recommended. The use of extension
cords wiII 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.
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

14 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 12 AWG and 10 AVVG
may also be used. DO NOT USE
16 OR 18 AWG.)
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 suppIy to circuit must
comply with the National
Electrical Code.
2. Circuit is not used to supply any
other electdca! needs.
3. Extension cords compiy with
specifications.
4. Circuit is equipped with a 15 amp
circuit breaker or 15 amp time
deIay 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.

Know Your Air Compressor
READ THiS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the iIIustrations with your unit to familiarize yourself with
the !ocation of various controls and adjustments. Save this manual for future
reference.
Safety VaRve
Description of Operation
Become familiar with these controls
before operating the unit.
On(l)/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 Vamve: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.
A10282
OutNet 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.
Regumator: 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: I--
The drain valve /
is located at [
the base of the

used to drain
condensation at the end of each use.
Oheck Valve: When the air
compressor is operating, the check
vane 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.
