symbol. It is used to alert
you to potential personal
injury hazards. Obey all
safety messages that follow
this symbol to avoid possible
injury or death.
DANGER indicates a
hazardous situation
which, if not avoided, will result
in death or serious injury.
WARNING indicates a
hazardous situation
which, if not avoided, could
result in death or serious injury.
CAUTION, used with
the safety alert
symbol, indicates a hazardous
situation which, if not avoided,
could result in minor or moderate
injury.

General Safety Warnings
WARNING Read all safety warnings
and instructions. Failure to follow the
warnings and instructions may result
in electric shock, re and/or serious
injury.
Save all warnings and instructions
for future reference.
Work area safety1.
Keep work area clean and well lit.a.
Cluttered or dark areas invite accidents.
Do not operate the Compressor inb.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Compressor motors
produce sparks which may ignite the
dust or fumes.
Keep children and bystanders awayc.
from an operating compressor.
Electrical safety2.
Compressor plugs must match thea.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded compressors.
Standard plugs and matching outlets
will reduce risk of electric shock.
Do not expose compressor to rainb.
or wet conditions. Water entering
a compressor will increase the risk of
electric shock.
Do not abuse the cord. Neverc.
use the cord for unplugging the
compressor. Keep cord away from

doing and use common sense when
operating this compressor. Do
not use this compressor while you
are tired or under the inuence of
drugs, alcohol or medication. A
moment of inattention while operating
a compressor may result in serious
personal injury.
Use personal protective equipment.b.
Always wear ANSI-approved eye
protection during setup and use.
Prevent unintentional starting.c.
Ensure the Power Switch (133) is in
the off-position before connecting
to power source or moving the
compressor.
Compressor use and care4.
Do not use the compressor if thea.
Power Switch (133) does not turn
it on and off. Any compressor that
cannot be controlled with the Power
Switch is dangerous and must be
repaired.
Disconnect the plug from theb.
power source before making any
adjustments, changing accessories,
or storing the compressor. Such
preventive safety measures reduce
the risk of starting the compressor
accidentally.
Store an idle compressor out ofc.
the reach of children and do not
allow persons unfamiliar with the
compressor or these instructions to
operate it. A compressor is dangerous
in the hands of untrained users.
Maintain the compressor. Keepd.
the compressor clean for better
and safer performance. Follow
instructions for lubricating and
changing accessories. Keep dry,
clean and free from oil and grease.
Check for misalignment or binding
of moving parts, breakage of parts
and any other condition that may
affect the compressor’s operation.
If damaged, have the compressor
repaired before use. Many accidents
are caused by a poorly maintained
compressor.
Use the compressor in accordancee.
with these instructions, taking into
account the working conditions and
the work to be performed. Use of
the compressor for operations different
from those intended could result in a
hazardous situation.
Service5.
Have your compressor serviced bya.
a qualied repair person using only
identical replacement parts. This will
ensure that the safety of the compressor
is maintained.

Check with a qualied electrician
if you are in doubt as to whether
the outlet is properly grounded.
Do not modify the power cord
plug provided with the
compressor. Never remove the
grounding prong from the plug.
Do not use the compressor if the
power cord or plug is damaged.
If damaged, have it repaired by a
service facility before use. If the

TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Turn the Power Switch “OFF”,
unplug the Compressor from its
electrical outlet, and release all
air pressure from the air tank
before assembling or making any
adjustments to the compressor.
Note: For additional information regarding the

2. Connect a regulator valve, an inline shut
off valve and a 1/4” NPT air hose to the
Quick Coupler (all sold separately). The
air hose must be long enough to reach
the work area with enough extra length
to allow free movement while working.
Note: Adding an in-line shutoff valve, such
as the female quick disconnect at the
compressor outlet, is an important
safety device because it controls
the air supply even if the air hose is
ruptured.
Depending on the tool which you will3.
be using with this compressor, you
may need to incorporate additional
components, such as an in-line oiler,
a lter, or a dryer (all sold separately).
Consult your air tool’s manual for needed
accessories.

6. AFTER the Compressor builds up

the Regulator Knob so that the air output
is enough to properly power the tool,
but the output will not exceed the tool’s
maximum air pressure at any time.
Turn the knob clockwise to increase
the pressure and counter-clockwise to
decrease pressure. Adjust the pressure
gradually, while checking the air output
gauge to set the pressure.
Note: At the beginning of the day’s rst use of
the Air Compressor, check for air leaks
by applying soapy water to connections
while the Air Compressor is pumping
and after pressure cut-out. Look for air
bubbles. If air bubbles are present at
connections, tighten connections. Do
not use the air compressor unless all
connections are air tight, the extra air
leaking out will cause the compressor to
operate too often, increasing wear on the
compressor.
Note: As long as the Power Switch (133) is
ON, the operation of the Air Compressor
is automatic, controlled by an internal
pressure switch. The Compressor will
turn on automatically when the air
pressure drops to 120 PSI, and will turn
off automatically when the air pressure
reaches 150 PSI. IMPORTANT: The
internal pressure switch is not user
adjustable. Do not make changes
to the air pressure settings of the
internal pressure switch. Any change
to the automatic pressure levels may
cause excess pressure to accumulate,
causing a hazardous situation and
voiding the warranty.

MAINTENANCE AND
SERVICING
Procedures not specically
explained in this manual must
be performed only by a qualied

TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION:
Turn the Switch “OFF”, unplug
the Compressor from its

air pressure from the air tank
before performing any
inspection, maintenance, or
cleaning procedures.
TO PREVENT SERIOUS INJURY
FROM COMPRESSOR FAILURE:
Do not use damaged equipment.
If abnormal noise or vibration
occurs, have the problem
corrected before further use.
Cleaning, Maintenance, and
Lubrication
BEFORE EACH USE,1. inspect the
general condition of the Air Compressor.
Check for loose hardware, misalignment
or binding of moving parts, cracked or
broken parts, damaged electrical wiring,
and any other condition that may affect
its safe operation.
AFTER USE,2. wipe external surfaces of
the compressor with a clean cloth.
3. WARNING! If the supply cord
of this compressor is damaged, it

Monthly:
Inspect Safety Valve.a.
1 To check for air leaks, apply soapy water
to joints while the Air Compressor is
